Description

Technology Field

[0001] The present invention relates to a rental service provision system and method, and more specifically, to a rental service provision system and method for internal combustion engine cleaning equipment of an automobile that can rapidly recover investment funds and stably obtain profits from the operation of the rental service, and furthermore, can conveniently check the schedule for maintenance work on the rental equipment, such as replacement of consumables and after-sales service. Background Technology

[0002] Generally, a rental service is a service that allows consumers to use a product by paying a fixed amount each month. Such rental services are being developed in the direction of renting household goods such as water purifiers, food waste disposers, cars, and bicycles, as well as heavy equipment and personnel.

[0003] Existing rental services are prepaid methods in which the consumer pays the rental fee in advance. In reality, whether the consumer uses the rental equipment during the rental period or leaves it unused, the rental contract is terminated when the rental equipment is returned at the end of the rental period. However, this is unreasonable, and to address this, Korean Registered Patent Publication No. 10-2341974 (hereinafter referred to as 'Prior Art 1') discloses a method of providing a rental service that links an app with a terminal device to allow payment for the amount of time used.

[0004] However, prior art 1 also describes a method where consumers prepay for the usage time and use the equipment, and also provides motivation and alarms to encourage consumers to use the rental equipment consistently after rental. Consequently, equipment rental businesses inevitably take a long time to recover the expensive initial business capital paid to prepare a large amount of rental equipment.

[0005] Korean Patent Publication No. 10-2645725 (hereinafter referred to as 'Prior Art 2') discloses a rental service system utilizing a deposit for after-sales service. Prior Art 2 allows for the early recovery of investment funds through a deposit for after-sales service processing. Prior art literature

[0007] Recently, amidst growing social interest in reducing greenhouse gas emissions, the production of vehicles that generate large amounts of greenhouse gases is being reduced. Studies have shown that these vehicles emit greenhouse gases because they fail to completely burn fuel in their engines. In particular, older vehicles emit more greenhouse gases due to performance degradation caused by impurities accumulated in the engines; therefore, vehicle inspection stations conduct annual performance tests on internal combustion engines and take measures to prohibit the operation of vehicles that fail the test. Under these circumstances, electric vehicles are expanding their market share. However, electric vehicles cannot yet replace vehicles used for transporting 20-foot or 40-foot containers, or so-called dump trucks used at construction sites.

[0008] Accordingly, we are preparing a rental service for automotive internal combustion engine cleaning equipment that can reduce greenhouse gas emissions and improve fuel efficiency by completely cleaning impurities accumulated in the engine. However, since the manufacturing cost per unit of internal combustion engine cleaning equipment is high, the initial investment cost for the rental service is inevitably substantial.

[0031] FIG. 1 illustrates a rental service system for internal combustion engine cleaning equipment for an automobile according to an embodiment of the present invention, FIG. 2 is an example diagram of a screen of a user interface and a display device of internal combustion engine cleaning equipment for an automobile used in the present invention, FIG. 3 is an example diagram for explaining the operating state of internal combustion engine cleaning equipment for an automobile used in the present invention, and FIG. 4 and FIG. 5 are measurement results of inspecting the performance of an automobile after cleaning the internal combustion engine using internal combustion engine cleaning equipment for an automobile used in the present invention.

[0032] First, referring to FIG. 1, the entire rental service system according to the present invention comprises a headquarters (110), an equipment rental business operator (120), and an equipment lessee (130). The headquarters (110) is the entity that performs acts including production, use, import, sale, or rental of internal combustion engine cleaning equipment (200) for automobiles. The headquarters (110) directs and supervises the entire rental service business. The headquarters (110) manages, supervises, repairs, and replacements not only for rental equipment but also for consumables such as filters and after-sales service for repairing aging equipment.

[0033] For a rental service, it is inevitably necessary to secure rental equipment by investing a large amount of capital in the initial stages. In order to recover the massive initial investment early, the company (110) enters into an agreement regarding the rental period and deposit while renting internal combustion engine cleaning equipment (200) for automobiles. Furthermore, in order for the equipment lessee (130) to actively use the rental equipment during the rental period so that both the equipment lessee (130) and the equipment rental business operator (120) can earn profit, the company (110) returns the deposit on the end date of the rental contract only when the total cumulative working time using the rental equipment during the rental period is fully satisfied according to the terms of the agreement, and even if the rental period ends, if the total cumulative working time is not satisfied, the contract is automatically renewed.

[0034] The equipment rental business operator (120) may, for example, be a business unit affiliated with the headquarters (110) and may be a business location within the same address. As another example, the equipment rental business operator (120) may be a dealership of the headquarters (110) distributed nationwide, such as a department store, a mart, or a home shopping business operator. According to this embodiment, the equipment rental business operator (120) may be operated under the direction and supervision of the headquarters (110) or may be operated independently. That is, the equipment rental business operator (120) may directly purchase the internal combustion engine cleaning equipment (200) for automobiles from the headquarters (110) and directly handle after-sales service, including replacing consumables such as filters and repairing aging equipment.

[0035] The equipment lessee (130) rents the internal combustion engine cleaning equipment (200) for automobiles, injects hydrogen through the intake port of the vehicle (e.g., SUV, truck, van, etc.) to remove impurities accumulated in the internal combustion engine, such as carbon / soot, and receives a fee from the vehicle owner for one cleaning work time (WORK TIMES) of the equipment (200) in return. The equipment lessee (130) may be, for example, a car repair shop operator, a parking lot manager, a gas station operator, a steam car wash business owner, etc.

[0036] Here, with reference to FIGS. 2 and FIG. 3, the internal combustion engine cleaning equipment (200) of a vehicle used in the present invention will be briefly described. The internal combustion engine cleaning equipment (200) of a vehicle is a device that generates hydrogen from water and cleans the internal combustion engine of a vehicle with the generated hydrogen. The display unit of the internal combustion engine cleaning equipment (200) of a vehicle includes a user interface that receives user operation commands and a display device that displays the cleaning time (WORK TIMES) (82) and cumulative working time (RUN TIMES) (83) of the equipment. Reference numeral 81 is a display area that displays the hydrogen gas emission amount of the internal combustion engine cleaning equipment (200) of a vehicle. The cleaning time (WORK TIMES) (82) refers to the operating time of the equipment and is displayed in a down-counting manner starting from a preset time. For example, it can be set to 45 minutes for small vehicles and 1 hour for large vehicles, respectively. After setting the cleaning work time and operating the equipment, the cleaning work time (WORK TIMES) (82) is displayed in a down-counting manner starting from 45 minutes in the case of a small size, for example.

[0037] In fact, a vehicle from which impurities have been removed through the internal combustion engine cleaning equipment (200) of the vehicle shows results of not only passing the smoke test at the vehicle inspection station but also improved engine output. FIG. 4 is a Hyundai Mighty 2.5-ton 2014 model with a mileage of 201,000 km, FIG. 5 is a Hyundai extra-long wheelbase Cargo 2002 model with a mileage of 1,500,000 km, and the results of measuring the performance of the vehicle before and after internal combustion engine cleaning using the internal combustion engine cleaning equipment (200) of the vehicle used in the present invention.

[0038] As can be seen in FIGS. 4 and 5, the Hyundai Mighty 2.5-ton 2014 model with a mileage of 201,000 km and the Hyundai Extra Long Wheelbase Cargo 2002 model with a mileage of 1,500,000 km failed the smoke test before cleaning, but passed the smoke test after cleaning the internal combustion engine using the internal combustion engine cleaning equipment (200) of the present invention. Such cases were also confirmed in test results for overseas vehicles such as Toyota and Nissan.

[0039] Hereinafter, with reference to FIG. 1, the operation of the entire rental service system according to the present invention will be described.

[0040] ① The headquarters (110) can handle all agreements regarding the implementation, operation, and after-sales management of rental services with equipment rental business operators (120), such as department stores, supermarkets, and home shopping business operators. ② The equipment rental business operator (120) can enter into a rental service contract with an equipment lessee (130), such as a car repair shop operator, a parking lot manager, a gas station operator, or a steam car wash individual business operator. ③ After receiving a deposit from the equipment lessee (130) who entered into the rental service contract, the headquarters (110) delivers and installs the internal combustion engine cleaning equipment (200) for automobiles.

[0041] ④ The equipment lessee (130) cleans the vehicle (300) requested by the customer using the internal combustion engine cleaning equipment (200) for the vehicle. ⑤ The equipment lessee (130) receives a fee from the customer for the use of the equipment (200) corresponding to one cleaning work time (WORK TIMES).

[0042] ⑥ On the payment date, the equipment lessee (130) provides the equipment rental business operator (120) with a screen image including the cumulative work time (RUN TIMES) displayed on the display device of the internal combustion engine cleaning equipment (200) of the vehicle. The equipment rental business operator (120) calculates the rental fee using the cumulative work time (RUN TIMES) and charges the calculated rental fee to the equipment lessee (130).

[0043] FIG. 6 is an exemplary diagram illustrating the configuration of a headquarters server (810) that performs a rental service for an internal combustion engine cleaning equipment of a vehicle according to the present invention.

[0044] The main server (810) is a device that performs a rental service for internal combustion engine cleaning equipment for automobiles, and the main server (810) can be controlled through an operator terminal. Multiple equipment renter terminals (131, 132, 133) are connected to the main server (810) via a commercial network (e.g., LTE 3 / 4 / 5G repeater) and can transmit rental equipment usage information to the main server (810).

[0045] As described above, the automobile internal combustion engine cleaning equipment (reference numeral 200 in FIG. 1) is a device that generates hydrogen from water and cleans the internal combustion engine of an automobile with the generated hydrogen, and may include a user interface and a display device that displays the cleaning time per run (WORK TIMES) and cumulative working time (RUN TIMES) of the equipment.

[0046] As illustrated in FIG. 6, the headquarters server (810) may be implemented to include a rental contract information processing unit (811) that stores rental contract information in a storage unit (814) and a rental fee processing unit (812).

[0047] The rental contract information processing unit (811) receives rental contract information from the operator terminal, including rental equipment model, rental period and contract termination / renewal and deposit agreement, fee and payment date agreement, equipment management agreement, and equipment lessee information.

[0048] For example, the agreement regarding the rental period, contract termination / renewal, and security deposit may include provisions stating that the security deposit will be returned on the end date of the rental contract only if the total cumulative working hours using the rented equipment during the rental period (e.g., 2 years) are fully met, and that even if the rental period ends, the contract will be automatically renewed if the total cumulative working hours are not met. Based on such an agreement regarding the rental period, contract termination / renewal, and security deposit, the equipment lessee will make efforts to acquire customers through more active sales activities, and the rental service operator will be able to obtain stable revenue.

[0049] The rental contract information processing unit (811) can extract cumulative working time (RUN TIMES) from a screen image containing equipment lessee information and cumulative working time (RUN TIMES) input from an operator terminal, and then determine whether all rental termination conditions are satisfied using the extracted cumulative working time (RUN TIMES) and the rental period, and process the termination of the rental contract or automatic renewal according to the result of the determination.

[0050] The operator terminal can receive a screen image containing cumulative run times displayed on the display device of the internal combustion engine cleaning equipment (200) of the vehicle on the payment date for each equipment lessee from the equipment lessee terminal (131, 132, 133). The operator can calculate the rental fee using the screen image information containing the cumulative run times and then send a rental fee cost invoice to the equipment lessee terminal (131, 132, 133).

[0051] The rental fee processing unit (812) can receive screen images including equipment lessee information and cumulative work time (RUN TIMES) and rental fee deposit information from the operator terminal and store them in the storage unit (814) in order to collect proof of payment for rental fees of each equipment lessee required for quarterly tax reporting.

[0052] The rental fee processing unit (812) can, for example, automatically calculate the rental fee for each equipment lessee. The rental fee processing unit (812) can calculate the rental equipment usage fee by extracting each accumulated work time (RUN TIMES) from the N+1th screen image containing equipment lessee information and accumulated work time (RUN TIMES) input from the operator terminal and the Nth screen image containing the previously stored equipment lessee's accumulated work time (RUN TIMES), and then calculating each extracted accumulated work time (RUN TIMES). Here, N is an integer starting from 1 and is the payment cycle.

[0053] Meanwhile, as the number of equipment lessees to be managed increases, the operator must manage tasks such as billing for fee payments, replacing consumables, extending or terminating contracts, as well as other tasks. As illustrated in FIG. 6, the headquarters server (810) of the present invention may be implemented to further include a rental equipment information processing unit (813) for the convenience of the operator in managing rental services.

[0054] The rental equipment information processing unit (812) can generate alarm information regarding fee payment, consumable replacement, and contract termination for each equipment lessee using the rental contract information for each equipment lessee stored in the storage unit (814), and transmit this to the operator terminal and the equipment lessee terminal.

[0055] FIG. 7 is a flowchart of a method for providing a rental service for equipment for cleaning an internal combustion engine of a vehicle according to an embodiment of the present invention. This embodiment describes a method for providing a rental service for equipment for cleaning an internal combustion engine of a vehicle, which is executed at an equipment rental business operator terminal (120) connected to an equipment lessee terminal (130) via a commercial network (e.g., an LTE 3 / 4 / 5G repeater).

[0056] The equipment rental business operator and the equipment lessee enter into a rental contract that includes the rental equipment model, the rental period, the contract termination / renewal and the deposit, the commission and the payment date, the equipment management agreement, and the equipment lessee information, and enter into the contract by mutual agreement. The equipment rental business operator terminal (120) stores the equipment rental contract entered into with the equipment lessee in the storage unit (911). When the deposit is received from the equipment lessee, the equipment rental business operator delivers and installs the internal combustion engine cleaning equipment for the vehicle.

[0057] The equipment rental business operator terminal (120) stores rental equipment usage information, including equipment lessee information input from the equipment lessee terminal (130) and the N+1th screen image including accumulated work time (RUN TIMES), in the storage unit (912).

[0058] The equipment rental business operator terminal (120) extracts each accumulated work time (RUN TIMES) from the N+1th screen image containing equipment lessee information and accumulated work time (RUN TIMES) and the Nth screen image containing the previously stored accumulated work time (RUN TIMES) of the equipment lessee, and then calculates the rental equipment usage fee by calculating each extracted accumulated work time (RUN TIMES) (913). The equipment rental business operator terminal (120) transmits a payment request message containing the calculated rental equipment usage fee to the equipment lessee terminal (130). Accordingly, the rental service operator can quickly recover the investment and stably obtain profits from the operation of the rental service.

[0059] Although not illustrated in FIG. 7, the equipment rental business operator terminal (120) can extract cumulative working time (RUN TIMES) from a screen image containing equipment lessee information and cumulative working time (RUN TIMES) input from the equipment lessee terminal (130), and then determine whether all rental termination conditions are satisfied using the extracted cumulative working time (RUN TIMES) and the rental period, and process the termination of the rental contract or automatic renewal according to the result of the determination.
