Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trunk lid switches in vehicles are prone to erroneous operations and durability issues due to moisture or foreign substances, and have complex assembly processes with soldered signal lines, leading to decreased assemblability and reliability.
Innovation Solution
A tailgate switching device with a compact and flexible housing, a substrate unit, and a cable connection system that includes a substrate pin and cable connector, enhancing watertightness and assembly convenience through a hermetically sealed structure and improved signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional trunk lid switch uses soldered connecting signal lines, then signal transmission can be achieved, but assemblability decreases and manufacturing complexity increases
Solution Approach 1:
The patent replaces the traditional soldered electrical connection system with a mechanical connector system. The cable connector and substrate pin provide a mechanical interface that eliminates the need for soldering, allowing for easy assembly and disassembly while maintaining reliable signal transmission between the switching unit and external systems.
2Reliability
If a conventional switch structure is used, then basic switching function is provided, but durability deteriorates due to moisture and foreign substances
Solution Approach 1:
The patent addresses the harmful effects of moisture and foreign substances by implementing a hermetically sealed housing structure. The housing completely encloses the switching unit, substrate, and cable connections, transforming the vulnerable internal components into a protected system that can withstand environmental exposure without degradation.
Solution Approach 2:
The cable connector and substrate pin assembly serves as an intermediary interface that maintains electrical connectivity while being protected within the sealed housing. This intermediate connection system allows signal transmission without creating openings that would permit moisture or foreign substance infiltration.
3Volume of moving object
If a compact structure is implemented, then space efficiency improves, but assembly convenience decreases
Solution Approach 1:
The patent divides the switch assembly into distinct modular segments: the housing, the substrate unit, and the cable connector assembly. This segmentation allows each component to be manufactured and prepared separately, then quickly assembled together through simple mechanical interfaces, maintaining ease of assembly despite the compact overall structure.
