Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional switches face challenges in preventing light leakage and foreign matter ingress due to separate manufacturing of light leak prevention structures and protective members, leading to increased production costs and inefficiencies in protecting internal components.
Innovation Solution
A switch design featuring a flexible cover plate made of rubber with a rubber dome, a transparent light emitting member cover, and a light leak prevention protrusion, which forms a sealed space and integrates these components for efficient light containment and protection against external forces and liquids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If separate light leak prevention structures and protective members are provided in conventional switches, then light leakage is prevented, but device complexity increases and manufacturing cost increases
Solution Approach 1:
The patent combines the light leak prevention structure and protective member into a single integrated component. The cover includes both the light leak prevention protrusion that blocks light and the protective function, eliminating the need for separate components and reducing overall device complexity while maintaining both light containment and protection capabilities.
Solution Approach 2:
The cover structure is designed to perform multiple functions simultaneously: it serves as both a light leak prevention mechanism through its protrusion design and a protective member for internal components. This multi-functional design reduces the number of parts needed and simplifies the overall switch structure.
2Ease of manufacture
If separate light leak prevention structures and protective members are manufactured separately and then integrated, then manufacturing flexibility is maintained, but productivity decreases and production cost increases
Solution Approach 1:
The light leak prevention structure and protective member are designed as a single integrated cover that can be manufactured in one piece. This eliminates the need for separate manufacturing and assembly steps, thereby increasing production efficiency and reducing labor costs while maintaining manufacturing flexibility through standard molding processes.
3Object-affected harmful factors
If separate light leak prevention structure and protective member are provided, then light containment is achieved, but reliability of protection against liquid and foreign matter decreases
Solution Approach 1:
The integrated cover design ensures that the light leak prevention protrusion and protective member form a unified barrier against liquids and foreign matter. This seamless integration eliminates gaps or interfaces between separate components that could serve as entry points for contaminants, thereby improving protection reliability while maintaining light containment effectiveness.
