Wireless Signal Transceiver for Vehicle Sliding Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing signal transmitter-receiver apparatus for vehicle sliding seats faces complexity in structure and assembly due to extra wiring requirements for sliding motion and has reduced receiving sensitivity from foreign objects, with increased costs and complexity from separate components to mitigate these issues.
Innovation Solution
A signal transmitter-receiver apparatus with a signal transmitter and receiver disposed in a rail below the sliding seat, fixed to the upper rail, and protected by a synthetic resin protector, using existing components to simplify structure and prevent sensitivity reduction, with optional photovoltaic elements for self-activation and reduced battery needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat signal wiring is extended to accommodate sliding motion, then the sliding seat can move freely, but the wiring structure becomes complex and assembly becomes complicated
Solution Approach 1:
The patent replaces the mechanical wiring connection system with a wireless communication system. The infrared transmitter and receiver eliminate the need for extended physical wiring, allowing the seat to slide freely without complex wiring arrangements while maintaining electrical connectivity for signal transmission.
Solution Approach 2:
The patent extracts the signal transmission function from the physical wiring system and separates it into an independent wireless communication subsystem. This removes the constraint of wiring length and complexity while preserving the essential function of signal transmission between the sliding seat and vehicle body.
2Reliability
If separate cover members are added to protect the infrared transmitter and receiver, then receiving sensitivity is maintained, but manufacturing cost and assembly complexity increase
Solution Approach 1:
The patent merges the protective cover function with the existing rail structure. Instead of adding separate cover members, the rail itself is designed to provide protection for the infrared transmitter and receiver, thereby maintaining receiving sensitivity without increasing component count or assembly complexity.
Solution Approach 2:
The rail structure is given multiple functions: it provides mechanical support for the sliding seat, guides the sliding motion, and simultaneously serves as a protective enclosure for the infrared transmitter and receiver. This multi-functionality eliminates the need for dedicated protective covers while maintaining system reliability.
