Working Machine Rental Control via Wireless Expiration Commands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing management systems for working machines lack efficient mechanisms for monitoring and controlling the operation of working machines, particularly in rental scenarios, where expiration dates and rental periods need to be managed effectively.
Innovation Solution
The proposed operation system for working machines includes a first control device and a first command device that can wirelessly output commands. This system obtains the expiration date of the working machine, calculates the current time, and judges whether the time meets the expiration date, restricting or allowing control accordingly. Additionally, a customer terminal, management servers, and a commander are integrated to manage rental periods and permissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional rental system uses physical engine start keys deposited to users, then the rental management is simple, but the control and monitoring of machine operation is insufficient and security is compromised
Solution Approach 1:
The patent replaces the mechanical system of physical engine start keys with an electronic control system. The control device receives operation commands wirelessly, verifies rental period information, and electronically controls engine startup. This substitution eliminates physical key management while providing enhanced security through automated verification and remote monitoring capabilities.
Solution Approach 2:
The patent introduces a command device as an intermediary between the rental management system and the control device. This intermediary verifies rental period information, determines whether operation permission should be granted, and transmits appropriate commands to the control device. This mediator layer enhances security by adding a verification step while maintaining system manageability.
2Loss of time
If the system automatically restricts operation after expiration date, then rental period control is precise, but the system complexity increases due to multiple control devices and communication protocols
Solution Approach 1:
The patent implements preliminary action by having the control device obtain rental period information in advance and continuously monitor the current time against the expiration date. The system automatically determines and executes operation restriction before the rental period expires, eliminating manual intervention and ensuring precise time-based control without requiring complex real-time decision-making infrastructure.
3Ease of operation
If wireless command transmission is used for operation control, then the ease of operation is improved, but the reliability of command transmission and security may be compromised
Solution Approach 1:
The patent implements feedback mechanisms where the control device receives wireless commands, verifies them against stored rental period information, and only executes authorized commands. The system provides feedback by comparing received commands with permission status, ensuring that wireless transmission maintains security through verification while preserving operational convenience through contactless control.

AI summary
An operation system of a working machine mounted on the working machine, including a first control device to control the working machine, and a first command device to output a command to the first control device wirelessly, the command relating to control of the first control device. The first command device includes a first obtaining part to obtain an expiration date of the working machine from outside, a first time calculating part to obtain time, a third processing part to judge whether the time obtained by the first time calculating part meets the expiration date, and a sixth communication part to output a first command when the time meets the expiration date, the first command restricting control of the first control device, and to output a second command when the time does not meet the expiration date, the second command allowing the first control device to be controlled without restriction.
