Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional switch elements suffer from malfunction and failure in high-voltage tests due to the accumulation of carbon residue, which forms a conductive layer connecting normally closed and normally open pins, leading to electrical shorts and safety certification issues.
Innovation Solution
A multi-instruction switch design featuring a housing with a conductive elastic plate and a support rack containing insulation plates and an insulation space within the limiting track, preventing carbon residue deposition between contact and trigger sections, thereby enhancing electrical insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional switch structure with a single insulation block is used, then the device complexity is low, but carbon residue accumulates on the insulation block forming a conductive layer that causes electrical shorts
Solution Approach 1:
The single insulation block is divided into multiple insulation blocks (first insulation block, second insulation block, third insulation block) positioned at different locations within the limiting track. Each insulation block addresses specific contamination zones, preventing carbon residue from forming continuous conductive paths between contacts.
Solution Approach 2:
Multiple insulation blocks are strategically placed as intermediary elements between conductive components (contact section, trigger section, normally closed pin, normally open pin). These insulation blocks act as mediators that block electrical conduction through carbon residue deposits, enhancing insulation reliability without requiring complete structural redesign.
2Ease of operation
If the elastic plate moves freely in the limiting track, then the ease of operation is good, but carbon residue scatters to the surroundings and deposits on the insulation block
Solution Approach 1:
The harmful function of carbon residue deposition is extracted and isolated by positioning multiple insulation blocks at specific locations within the limiting track. The insulation blocks capture and contain carbon residue deposits at designated zones, preventing them from forming continuous conductive paths while allowing the elastic plate to move freely for smooth operation.
Solution Approach 2:
Different regions within the limiting track are assigned different functional qualities through strategic placement of insulation blocks. The first insulation block addresses the contact section area, the second insulation block addresses the trigger section area, and the third insulation block provides additional insulation. This local differentiation prevents carbon residue from creating harmful conductive paths while maintaining operational smoothness.
