Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stop-lamp switch mounting mechanisms are complex and costly, requiring precise positioning and stable maintenance to ensure proper operation, which complicates vehicle assembly and increases manufacturing costs.
Innovation Solution
A one-touch stop-lamp switch system featuring a mounting bracket, switch cover, cover locker, and rotation-restraining locker that allows quick and simple mounting by adjusting the switch cover's position through rotational engagement and locking mechanisms, preventing direct contact with the brake pedal and ensuring stable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a complex mounting mechanism is used to ensure precise positioning of the stop-lamp switch, then positioning accuracy is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The stop-lamp switch is designed with self-positioning features including positioning protrusions that fit into corresponding positioning grooves on the brake pedal assembly. The switch body automatically aligns and secures itself during installation without requiring complex external positioning mechanisms, thereby achieving precise positioning while simplifying the overall mounting structure.
Solution Approach 2:
The mounting structure is divided into distinct modular components: the stop-lamp switch body with integrated positioning protrusions, the brake pedal assembly with positioning grooves, and separate locking mechanisms. This segmentation allows each component to be manufactured independently with standard tolerances and assembled through simple engagement, reducing both complexity and manufacturing cost while maintaining positioning accuracy.
2Ease of manufacture
If a simple mounting mechanism is used to reduce manufacturing cost, then ease of manufacture is improved, but positioning stability and precision deteriorate
Solution Approach 1:
The stop-lamp switch is pre-equipped with positioning protrusions and the brake pedal assembly is pre-formed with corresponding positioning grooves during manufacturing. This preliminary preparation of positioning features allows for rapid and accurate assembly without requiring complex adjustment mechanisms or precision machining during the mounting process, thereby maintaining positioning stability while simplifying installation.
3Stability of the object's composition
If multiple locking mechanisms are added to ensure stable positioning, then positioning stability is improved, but device complexity increases
Solution Approach 1:
The positioning and locking functions are merged into a single integrated mechanism. The positioning protrusions on the switch body engage with the positioning grooves on the brake pedal assembly to simultaneously provide both positioning and locking functionality. This consolidation eliminates the need for separate locking mechanisms, achieving stable positioning while maintaining simplicity.
4Manufacturing precision
If precise positioning mechanisms are implemented, then manufacturing precision is improved, but assembly time and complexity increase
Solution Approach 1:
The stop-lamp switch automatically positions itself during assembly through its self-positioning protrusions that fit into the brake pedal assembly's grooves. This self-positioning capability eliminates the need for complex alignment procedures or specialized tooling during assembly, thereby achieving precise mounting while maintaining fast assembly speed and high productivity.
