Detailed Description

A. Embodiment 1:

(A-1) overall Structure of System:

fig. 1 is an explanatory diagram showing a schematic configuration of an energy generation system 10 according to embodiment 1 of the present invention. The energy generation system 10 of the present embodiment is a system for generating energy using biomass. The energy generation system 10 includes a practitioner 20, an energy generation device 30, a1 st control unit 22, a2 nd control unit 32, a3 rd control unit 40, and a display unit 50.

The practitioner 20 is a practitioner who processes food and produces food waste. The practitioner 20 may be, for example, a food retailer such as a convenience store or a supermarket, a restaurant, a hotel, a hospital, or a complex facility in which a plurality of practitioners are grouped together.

The energy generation device 30 is a device that generates energy or an energy source (hereinafter, the energy and the energy source are also collectively referred to as energy or the like) using biomass such as food waste collected from the practitioner 20. The energy generation device 30 may be, for example, a device that generates methane as an energy source from biomass by methane fermentation using microorganisms, or a device that generates hydrogen as an energy source by reforming the obtained methane. The energy generation device 30 may be a device that generates hydrogen as an energy source from biomass by hydrogen fermentation using a microorganism, or a device that supplies organic acid as a by-product of hydrogen fermentation to methane fermentation to further generate methane as an energy source. Further, the energy generation device 30 may be configured as follows: the fuel cell system further includes a fuel cell for generating electricity using hydrogen, and generates electric energy by generating electricity using the hydrogen generated as described above.

The 1 st control unit 22, the 2 nd control unit 32, and the 3 rd control unit 40 are each configured as a logic circuit centered on a microcomputer, and specifically include a CPU that performs operations and the like according to a preset control program, a ROM that stores in advance a control program, control data and the like necessary for the CPU to perform various types of arithmetic processing, and a RAM that temporarily reads and writes various types of data necessary for the CPU to perform various types of arithmetic processing; and input/output ports for inputting/outputting various signals.

The 1 st control unit 22 is a control device installed in facilities such as a convenience store as the worker 20 and performs control related to distribution management of food as a product of the worker 20. The 1 st control unit 22 includes at least a1 st information generating unit 25 as a functional block. The 1 st information generating unit 25 performs control related to the disposal and collection of the commodity, such as expiration, and generates 1 st information indicating that the practitioner 20 has discarded the biomass, which is food waste. In the present embodiment, the 1 st information includes 1 st identification information for associating with the 2 nd information generated by the 2 nd control unit 32 described later. The 1 st identification information can be formed as, for example, the following information: the information for identifying which of the practitioners 20 has collected the biomass related to the 1 st information is collected in the operation of collecting the biomass. The generation of the 1 st information will be described in detail later.

The 2 nd control unit 32 is a control device provided in the energy generation device 30 and performs control related to an operation of receiving the biomass collected from the practitioner 20 and an operation of supplying the collected biomass to a process for generating energy or the like. The 2 nd control unit 32 includes at least a2 nd information generating unit 35 as a functional block. The 2 nd information generating unit 35 generates the 2 nd information indicating that energy or the like has been generated using the biomass collected from the practitioner 20. In the present embodiment, the 2 nd information includes the 2 nd identification information for associating with the 1 st information generated by the 1 st control unit 22 described above. The 2 nd identification information can be formed as, for example, the following information: for identifying which practitioner discarded the biomass related to the 2 nd information and which biomass was collected in which collection operation. The generation of the 2 nd information will be described in detail later.

The 3 rd control unit 40 is connected to the 1 st control unit 22 and the 2 nd control unit 32 by wire or wireless, and receives the 1 st information from the 1 st control unit 22 and the 2 nd information from the 2 nd control unit 32. In the present embodiment, the 3 rd control unit 40 is connected to the 1 st control unit 22 and the 2 nd control unit 32 via the internet. When the 1 st information is generated, the 1 st information is automatically transmitted from the 1 st control unit 22 to the 3 rd control unit 40, and when the 2 nd information is generated, the 2 nd information is automatically transmitted from the 2 nd control unit 32 to the 3 rd control unit 40. The 3 rd control unit 40 may be installed in facilities such as a convenience store as the practitioner 20.

The 3 rd control unit 40 includes at least a3 rd information generating unit 42 as a functional block. The 3 rd information generating unit 42 acquires the 1 st information and the 2 nd information, and generates the 3 rd information indicating that the biomass discarded by the worker 20 is collected and energy or the like is generated. In the present embodiment, as described above, the 1 st information includes the 1 st identification information, and the 2 nd information includes the 2 nd identification information. Therefore, the 3 rd information generating unit 42 determines whether or not the acquired 1 st information and 2 nd information relate to the same biomass after a series of operations related to discarding and collecting by using the correspondence relationship between the 1 st identification information and the 2 nd identification information, and generates the 3 rd information by using the 1 st information and the 2 nd information relating to the same biomass. The generation of the 3 rd information will be described in detail later.

The display unit 50 is a device that displays the 3 rd information generated by the 3 rd information generating unit 42. The display unit 50 is not particularly limited as long as it can display the 3 rd information, and may be formed as a display device installed in a facility such as a convenience store as the practitioner 20, for example. Alternatively, the display portion 50 may be formed as a display device that is provided in a vehicle owned by the practitioner 20 so as to be visually recognizable from the outside of the vehicle. The display unit 50 may be an information terminal for displaying the disclosed 3 rd information on the homepage of the practitioner 20, or an information terminal for displaying the 3 rd information as, for example, a banner advertisement on a video distribution site on the internet or the like. Examples of such an information terminal include a personal computer, a tablet, and a mobile phone. In addition, the display section 50 may be formed as a television receiver for displaying the 3 rd information as the television CM. The display unit 50 preferably displays the 3 rd information so that the 3 rd information can be provided to a large unspecified number of people.

(A-2) control method of System:

fig. 2 is a process diagram of a control method of the energy generation system 10 according to the present embodiment. First, the CPU of the 1 st control unit 22 acquires food waste information (step T100). The food waste information includes information indicating the type of food waste. For example, the operator of the apparatus including the 1 st control unit 22 among the practitioners 20 can perform the step T100 by reading the barcode of the discarded commodity. The CPU of the 1 st control unit 22 can recognize the type of the commodity to be discarded by an input from the barcode reader connected to the above-described apparatus including the 1 st control unit 22. In addition, the storage unit in the 1 st control unit 22 may store an estimated value of the amount of energy or the like obtained when each product is supplied as biomass to the generation of energy or the like. Thus, the CPU of the 1 st control unit 22, to which the barcode read signal is input, can derive the amount of energy and the like obtained from the commodity to be discarded by referring to the storage unit. Therefore, the food waste information acquired in the step T100 may include the fact that the product from which the barcode has been read is discarded and information indicating the amount of energy or the like obtained from the product.

The practitioner 20 accumulates biomass to be discarded until the next arrival of a vehicle for transporting the biomass, for example. Meanwhile, the CPU of the 1 st control unit 22 repeats the acquisition of the food waste information in the step T100 and accumulates the food waste information. When the shipment of the biomass transportation vehicle is detected, the CPU of the 1 st control unit 22 generates the 1 st information using the food waste information stored up to this point, and transmits the generated 1 st information to the 3 rd control unit 40 (step T110). In the present embodiment, a sensor for detecting a vehicle for transporting out biomass is provided in facilities such as a convenience store as the practitioner 20, and the transport is detected by transmitting a detection signal of the sensor to the 1 st control unit 22.

As described above, the 1 st information includes at least information indicating that the practitioner 20 discarded the biomass, and also includes 1 st identification information for associating with the 2 nd information generated by the 2 nd control unit 32. The 1 st identification information may be, for example, the date and time of collection of the biomass by the practitioner 20, specifically, the date and time of detection of shipment by the biomass shipment vehicle. In addition, when the energy generation device 30 collects biomass discarded by a plurality of practitioners 20 and generates energy or the like, the 1 st information may include information indicating a practitioner who discards the biomass related to the 1 st information. The information indicating the practitioner who discards the biomass is also referred to as 3 rd identification information. As described above, the 1 st information may further include information indicating the amount of energy or the like obtained from the biomass to be discarded.

After the biomass is carried out from the worker 20, when the carrying-in of the biomass by the biomass carrying-out vehicle is detected in the energy generation device 30, the CPU of the 2 nd control unit 32 generates the 2 nd information and transmits the 2 nd information to the 3 rd control unit 40 (step T120). In the present embodiment, the energy generation device 30 is provided with a sensor for detecting the vehicle for transporting biomass, and the transport is detected by transmitting a detection signal of the sensor to the 2 nd control unit 32.

As described above, the 2 nd information includes at least information indicating that energy or the like is generated using biomass recovered from the practitioner 20, and also includes the 2 nd identification information for associating with the 1 st information generated by the 1 st control unit 22. The 2 nd identification information may be, for example, the date and time of biomass reception in the energy generation device 30, specifically, the date and time of detection of the approach by the biomass transport-out vehicle. In addition, when the energy generation device 30 collects biomass discarded by a plurality of practitioners 20 and generates energy or the like, the 2 nd identification information may include information indicating a practitioner who discards the biomass related to the 2 nd information. The information indicating the practitioner who discards the biomass is also referred to as 4 th identification information. In this case, for example, the biomass transportation vehicle may be configured to transmit a signal for identifying the practitioner 20 who has discarded the biomass, and the receiving device provided in the energy generation device 30 may receive the signal and transmit the signal to the 2 nd control unit 32.

When the 1 st control unit 22 transmits the 1 st information and the 2 nd control unit 32 transmits the 2 nd information, the 3 rd control unit 40 receives the 1 st information and the 2 nd information (step T130). Then, the CPU of the 3 rd control unit 40 generates the 3 rd information using the 1 st information and the 2 nd information (step T140). As described above, the 1 st information includes the 1 st identification information, and the 2 nd information includes the 2 nd identification information. Therefore, the 3 rd information generating unit 42 can generate the 3 rd information by recognizing that the acquired 1 st information and the acquired 2 nd information are information on the same biomass after a series of operations related to discarding and collecting, using the correspondence relationship between the 1 st identification information and the 2 nd identification information.

As described above, the 3 rd information includes at least information indicating that the biomass discarded by the practitioner 20 is collected and energy or the like is generated. In addition, when the 1 st information includes information indicating the amount of energy or the like obtained from the biomass discarded by the practitioner 20, the 3 rd information may include information indicating the amount of energy or the like generated using the biomass collected from the practitioner 20.

When the CPU of the 3 rd control unit 40 generates the 3 rd information, the 3 rd control unit 40 transmits the generated 3 rd information to the display unit 50, and displays the 3 rd information on the display unit 50 (step T150). For example, when the display unit 50 is a display device provided in the aforementioned practitioner 20, the 3 rd control unit 40 may transmit an instruction signal for displaying the generated 3 rd information to the display device by wire or wireless. Alternatively, the 3 rd control unit 40 may transmit the 3 rd information to a server holding information to be published as a banner advertisement or a television CM by accessing the server holding information to be published on the homepage of the practitioner 20, or the server holding information to be published as a banner advertisement or a television CM, for example, via the internet.

The specific content displayed on the display unit 50 is not particularly limited as long as the 3 rd information can be displayed. For example, the case where the biomass discarded by the practitioner 20 is collected and the energy or the like is generated may be displayed, or the case where whether the energy or the like is currently generated may be displayed. When the 3 rd information generated by the 3 rd information generating unit 42 includes the amount of generated energy or the like as described above, the amount of generated energy or the like may be displayed in addition to the generation of the energy or the like. The content displayed on the display unit 50 may be updated every time the 3 rd information generating unit 42 newly generates the 3 rd information, for example. Alternatively, the update is performed every predetermined time, for example, every day at a predetermined time. From the viewpoint of displaying information indicating that the biomass discarded by the practitioner 20 is being collected and the energy or the like is being generated, the display of the 3 rd information by the display unit 50 or the update of the 3 rd information displayed on the display unit 50 may be continuously performed. Here, continuous means not always required, nor at equal time intervals, but means repeated execution.

According to the energy generation system 10 of the present embodiment configured as described above, since the 3 rd information indicating that the biomass discarded by the practitioner 20 is collected and the energy or the like is generated is displayed, the biomass can be effectively used and the use of the biomass can be further advanced. For example, in the case of generating energy or the like using biomass, although the cost is higher than the case of merely discarding as food waste without utilizing biomass, the social evaluation by the practitioner 20 is improved, and the use of biomass can be promoted. In particular, when the 3 rd information includes information indicating the amount of energy or the amount of energy source generated by using the biomass collected from the practitioner 20, it is possible to more specifically display a mode of utilizing the biomass discarded by the practitioner 20.

In fig. 1, a single facility such as a convenience store is shown as the practitioner 20, but the facility may be configured differently. For example, the practitioner 20 may be an aggregate of facilities such as a plurality of convenience stores belonging to the same group in a chain affiliation or the like, or an aggregate of facilities such as a plurality of retail stores operated by the same business entity. In this case, the 3 rd information may be generated and displayed as the whole of the practitioner 20 having a plurality of facilities. For example, the 3 rd information indicating the total amount of energy and the like generated by collecting biomass discarded by each of a plurality of facilities owned by the practitioner 20 may be displayed. In this case, the energy generation device 30 does not need to be single for the plurality of facilities, and a plurality of energy generation devices 30 may be used for each facility, using different energy generation devices 30, and the like. In this case, the 2 nd information may be transmitted from each energy generation device 30 to the 3 rd control unit 40. In this case, the 3 rd information may be displayed for each facility, may be displayed separately for each facility as the whole of the practitioner 20, or may be displayed as a result of concentration on the whole of the practitioner 20.

B. Embodiment 2:

fig. 3 is an explanatory diagram showing a schematic configuration of an energy generation system 110 according to embodiment 2 of the present invention. In the energy generation system 110 of the present embodiment, the same reference numerals are given to the portions common to the energy generation system 10 of embodiment 1, and detailed description thereof is omitted.

In the energy generation system 110 of the present embodiment, the practitioner 120 uses energy or the like generated by the energy generation device 30 using biomass discarded by the practitioner 120. Specifically, the practitioner 120 includes a fuel cell 127 as a power generation device that generates power using hydrogen and oxygen. The practitioner 120 receives a supply of hydrogen as an energy source as energy or the like generated by the energy generation device 30, and uses the hydrogen to generate electricity in the fuel cell 127, thereby supplying at least a part of the electric power consumed by the practitioner 120.

In such a case, the 3 rd information may further include information indicating that the practitioner 120 uses energy or an energy source generated using biomass. In the present embodiment, the practitioner 20 includes the 1 st control unit 122 instead of the 1 st control unit 22. The 1 st control unit 122 includes a 4 th information generating unit 27 in addition to the 1 st information generating unit 25. The 4 th information generating unit 27 generates information indicating the energy and the like generated by the practitioner 120 using the biomass as the 4 th information. For example, when the fuel cell 127 generates electricity using hydrogen supplied from the energy generation device 30, the 4 th information generation unit 27 can generate the 4 th information by inputting a signal indicating that the electricity generation of the fuel cell 127 is detected to the 4 th information generation unit 27. As described above, when the 1 st information and the 4 th information are generated, the 1 st control unit 122 transmits the 4 th information to the 3 rd control unit 40 together with the 1 st information. As a result, the 3 rd information generating unit 42 generates the 3 rd information including the 4 th information, and the 3 rd information including the 4 th information is displayed on the display unit 50.

Even with such a configuration, the same effects as those of embodiment 1 are obtained. Further, by using energy or the like generated by the biomass discarded by the practitioner 120, it is possible to contribute to a reduction in the amount of carbon dioxide generated by the activity of the practitioner 120 itself. Further, by displaying the 3 rd information including information indicating the energy and the like generated by the practitioner 120 using the biomass, the social evaluation of the practitioner 120 can be further improved, and the power of biomass utilization can be further improved.

In fig. 3, the practitioner 120 includes the fuel cell 127 and receives the supply of hydrogen as the energy or the like generated by the energy generation device 30, but may have a different configuration. For example, when the energy generation device 30 generates electric power as energy, the practitioner 120 may receive supply of electric power from the energy generation device 30 and use the electric power.

In fig. 3, the practitioner 120 uses hydrogen supplied from the energy generation device 30 in order to obtain the electric power consumed by the practitioner 120 itself, but the supplied hydrogen may be provided for a fee or a fee. For example, the practitioner 120 may have facilities for processing foods and a hydrogen station for supplying hydrogen to a fuel cell vehicle or the like. In this case, the hydrogen supplied from the energy generation device 30 may be sold at the hydrogen station.

C. Embodiment 3:

fig. 4 is an explanatory diagram showing a schematic configuration of an energy generation system 210 according to embodiment 3 of the present invention. In the energy generation system 210 of the present embodiment, the same reference numerals are given to the portions common to the energy generation system 10 of embodiment 1, and detailed description thereof is omitted.

In the energy generation system 210 of the present embodiment, there are a plurality of practitioners 220a, 220b, 220 c. In fig. 4, the number of practitioners is set to 3, but may be any number of 2 or more. Practitioners 220a, 220b, and 220c may each have a plurality of facilities for discarding biomass. For example, each of the practitioners 220a, 220b, and 220c may be an aggregate of facilities such as a plurality of convenience stores belonging to the same group, or an aggregate of facilities such as a plurality of retail stores operated by the same business entity.

In this embodiment, at least one of the practitioners 220a, 220b, 220c uses the energy or energy source generated by the energy generating device 30. The 3 rd information generated by the 3 rd information generating unit 42 includes information indicating that the at least one practitioner uses energy generated using biomass or the like. Hereinafter, a configuration in which each practitioner uses the electric power generated by the energy generation device 30 will be described as an example.

In the present embodiment, the practitioners 220a, 220b, and 220c each include the 1 st information generating unit 25. In fig. 4, a single energy generation device 30 for generating energy or the like from biomass discarded by practitioners 220a, 220b, and 220c is shown, but a plurality of energy generation devices 30 may be provided and the energy generation devices 30 used by the practitioners may be different. The energy generation system 210 of the present embodiment includes a3 rd control unit 240 instead of the 3 rd control unit 40 of embodiment 1. The 3 rd control unit 240 includes at least the 3 rd information generating unit 42 as a functional block. The 3 rd control unit 240 may be provided, for example, by a third party different from any of the practitioners 220a, 220b, and 220 c.

The 3 rd control unit 240 acquires the 1 st information from the 1 st information generating unit 25 provided in each of the practitioners 220a, 220b, and 220c in step T130 of fig. 2. In the present embodiment, the 1 st information acquired by the 3 rd control unit 240 from the 1 st information generating unit 25 of each of the practitioners 220a, 220b, and 220c includes the 3 rd identification information indicating the practitioner who discarded the biomass and is related to the 1 st information. In step T130 of fig. 2, the 3 rd control unit 240 acquires the 2 nd information about the biomass discarded by the practitioners 220a, 220b, and 220c from the 2 nd information generating unit 35 of the energy generating apparatus 30. In the present embodiment, the 2 nd information generated by the 2 nd information generating unit 35 of the energy generation device 30 includes the 4 th identification information indicating the practitioner who discards the biomass, which is related to the 2 nd information. The 3 rd control unit 240 uses the 1 st information and the 2 nd information described above in step T140 of fig. 2 to associate the 3 rd identification information with the 4 th identification information, and generates the 3 rd information for each of the practitioners 220a, 220b, and 220 c. In step T150, the display unit 50 that acquires the 3 rd information from the 3 rd control unit 240 collectively displays the 3 rd information generated by the 3 rd control unit 240 for each of the practitioners 220a, 220b, and 220 c.

In the present embodiment, the 3 rd information further includes the amount a of waste biomass, the amount b of consumed electric power, the amount c of consumed electric power from biomass (hereinafter referred to as the amount c of consumed electric power from biomass) among the amounts of electric power consumed by the respective practitioners, and the ratio (c/b) of the amount c of consumed electric power from biomass to the amount b of consumed electric power. For example, the amount a of waste biomass for each practitioner can be determined in the following manner. That is, in the step T100, the food waste information acquired by the 1 st control unit 22 of each practitioner may include information indicating the weight of the waste. In the case where the 3 rd information is generated by the 3 rd control unit 240 in the step T140, the 3 rd information generating unit 42 may sum the amounts of biomass discarded by the respective practitioners for a predetermined period of time, and may calculate the amounts a1, a2, and a3 of the discarded biomass for the respective practitioners 220a, 220b, and 220c as the amount a of the discarded biomass included in the 3 rd information. In order to obtain the information indicating the weight of the waste in the step T100, for example, the weight of each product may be stored in a storage unit in the 1 st control unit 22 in advance, and when the barcode of the product to be discarded is read by each practitioner, the 1 st control unit 22 of each practitioner may refer to the storage unit to derive the information indicating the weight of the product.

By including information indicating the amount of electric power consumed by the practitioners 220a, 220b, and 220c for a predetermined period of time in the 1 st information, the 3 rd information generation unit 42 can acquire the amount of electric power consumption b. The power consumption c from biomass may be any power amount obtained from the energy generation device 30 by each practitioner within a predetermined period, and can be acquired by the 3 rd information generation unit 42 by including information indicating the power amount in the 1 st information. The 3 rd information generating unit 42 of the present embodiment calculates (c/b) by using the above-described amount of consumed electric power b and the amount of consumed electric power c derived from biomass, and includes this in the 3 rd information.

Fig. 5 is an explanatory diagram showing an example of the 3 rd information displayed on the display unit 50 according to embodiment 3. Fig. 5 shows a list of the amount a of waste biomass, the amount b of power consumption, the amount c of power consumption from biomass, and (c/b) for each practitioner. Fig. 5 is an example, and the 3 rd information to be displayed may include information of a different kind from that in fig. 5.

With such a configuration, the same effects as those of embodiment 1 and embodiment 2 are obtained. Further, by displaying the 3 rd information on a plurality of practitioners collectively, comparison with other practitioners is performed, and as a result, the motivation of each practitioner for utilizing biomass can be improved, and social evaluation of the practitioner who actively utilizes biomass can be further improved, and utilization of biomass can be further advanced.

In embodiment 3, the energy generation device 30 generates electric power as energy, and each practitioner uses the electric power generated by the energy generation device 30, but may have a different configuration. For example, the energy generator 30 may generate hydrogen as an energy source, and each practitioner may use the hydrogen generated by the energy generator 30 to generate power for the fuel cell, as in embodiment 2. In this case, the amount of power consumption c from the biomass shown in fig. 5 may be any amount of power that can be generated by each practitioner using the hydrogen from the biomass supplied from the energy generation device 30.

D. Other embodiments:

(D1) in each of the above embodiments, the practitioner and the energy generation device 30 are disposed at separate locations, and in embodiment 3, the energy generation device 30 uses biomass collected from a plurality of practitioners, but may be configured differently. For example, the energy generation device 30 may be provided for each practitioner in the vicinity of each practitioner.

(D2) In each of the above embodiments, the 1 st information is generated using the food waste information obtained by reading the barcode of the commodity to be discarded in the step T100, but a different configuration may be adopted. For example, the 1 st control unit 22 may generate the 1 st information indicating that the biomass has been discarded when acquiring a signal indicating that the transport by the biomass transport vehicle is detected. In this case, if a sensor for automatically detecting the weight of the transported biomass is provided for each practitioner, the 1 st control unit 22 can include information indicating the weight of the biomass in the 1 st information to be generated by acquiring the detection value of the sensor. Further, if the 1 st control part 22 stores an estimated value of the amount of energy or the like generated per unit weight of biomass in advance, it is possible to obtain an estimated value of the amount of energy or the like generated from the discarded biomass using the estimated value. This allows information indicating the amount of energy or the like generated from the waste biomass to be included in the 1 st information and the 3 rd information.

Instead of transporting the biomass from each practitioner, the weight of the biomass used for energy generation may be detected when the biomass is transported into the energy generation device 30. In this case, for example, if an estimated value of the amount of energy or the like generated per unit weight of biomass is stored in advance in the 2 nd control unit 32, the 2 nd control unit 32 can obtain an estimated value of the amount of energy or the like generated from the waste biomass. In this case, information indicating the amount of energy or the like generated from the waste biomass can be included in the 2 nd information and the 3 rd information.

(D3) In the above embodiments, the 1 st information includes the 1 st identification information, and the 2 nd information includes the 2 nd identification information, but may be configured differently. For example, as in the case where the energy generation device 30 is provided for a practitioner, if the correspondence between the biomass discarded by the practitioner and the biomass collected by the energy generation device 30 and used for generation of energy or the like is clear, the 1 st identification information and the 2 nd identification information for associating the 1 st information and the 2 nd information may not be used.

The present invention is not limited to the above-described embodiments, and can be realized in various configurations without departing from the spirit and scope thereof. For example, the technical features of the embodiments corresponding to the technical features of the respective aspects described in the summary of the invention can be appropriately replaced or combined so as to solve a part or all of the above-described problems or a part or all of the above-described effects. In addition, as long as the technical features are not described as essential technical features in the present specification, the technical features can be appropriately deleted.
