Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for checking the operation and connection state of wirelessly connected switches and operation units in vehicles are inefficient, requiring physical connections and lengthy operation current checks, which hinder thorough electrical equipment quality assessment before vehicle release.
Innovation Solution
A wireless checking system comprising a switch, an operation unit, and diagnosis equipment that wirelessly communicate to detect and diagnose the operation state and connection status of the switch and operation unit, using switch and operation controllers to generate and transmit current detection signals, enabling remote and efficient evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an operation current check is performed by connecting a current measurement device to a battery by wiring and mounting check equipment to a diagnosis connector, then the current value can be determined, but the checking time becomes excessively long and the entire electrical equipment cannot be checked
Solution Approach 1:
The patent replaces the mechanical wiring connection system with a wireless communication system. The diagnosis equipment communicates with the switch and operation unit through wireless signals, eliminating the need for physical connection of current measurement devices and check equipment, thereby dramatically reducing checking time while maintaining diagnostic capability
Solution Approach 2:
The patent uses wireless signal transmission to copy the function of physical current measurement. Instead of directly measuring current through wired connections, the system uses wireless communication to transmit operational data from the switch and operation unit to the diagnosis equipment, achieving the same diagnostic purpose more efficiently
2Loss of information
If a wire or wireless connector is installed inside the vehicle for engagement check, then data can be transmitted to check equipment, but the device complexity increases
Solution Approach 1:
The patent extracts the data transmission function from the physical connector system and implements it through wireless communication. By removing the need for internal wire or wireless connectors, the system eliminates the associated complexity while maintaining the ability to transmit operational data from the switch and operation unit to external check equipment
Solution Approach 2:
The patent introduces wireless communication as an intermediary between the switch/operation unit and the check equipment. This intermediary enables data transmission without requiring physical connectors inside the vehicle, simplifying the overall system architecture while ensuring reliable information transfer for engagement checks
