Vehicle Push Switch Assembly With Integral Damper for Noise Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional push switches in vehicles face issues with noise and vibration due to inaccurate damper standards during assembly, leading to contact errors and operational inconsistencies.
Innovation Solution
A push switch unit with an integral damper in a compact, double-shot injection-molded structure, featuring a unit stopper section that is at least partially injection-molded, to ensure precise manufacturing and minimize noise and vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional push switch with a separately assembled damper is used, then the damper can be installed as a constituent element, but the moving block and damper are manufactured separately and assembled manually, making it difficult to precisely implement damper standards during actual push and return operations, resulting in contact errors, noises, shocks, or tilt operations
Solution Approach 1:
The damper is integrated directly into the moving block as a single molded part, eliminating the need for separate manufacturing and manual assembly of the damper and moving block. This integration ensures precise implementation of damper standards while simplifying the overall assembly structure.
Solution Approach 2:
The damper is pre-formed as an integral part of the moving block during the molding process, rather than being assembled separately afterward. This preliminary formation ensures precise positioning and eliminates assembly-related contact errors, noises, and shocks.
2Adaptability or versatility
If multiple switch devices are installed around the driver's seat, then various vehicle amenities can be provided, but the switch devices require compact design to prevent interference between them
Solution Approach 1:
Multiple switch devices are integrated into a single compact switch unit with a unified housing and shared internal components. This merging approach provides multiple vehicle amenities functions while maintaining a compact overall volume that prevents interference between switches.
Solution Approach 2:
The switch unit is designed as a multi-functional device that can accommodate various types of switches (push switches, rotary switches, sliding switches) within a single compact housing, enabling diverse vehicle amenities while maintaining space efficiency.
