Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple reflector cups are used to meet multiple light source requirements, then the illumination device can meet various light source requirements, but the device becomes larger in size and inconvenient to carry
Solution Approach 1:
The patent applies universality by designing a single light guiding part that can serve multiple light source emitting parts. The light guiding part is configured to be selectively matched with different light source emitting parts through a switching mechanism, allowing one component to perform multiple functions rather than requiring separate reflector cups for each light source.
Solution Approach 2:
The patent merges multiple light source emitting parts and a single light guiding part into an integrated system. Instead of having separate reflector cups for each light source, the design combines them into one unified illumination device where the light guiding part can be selectively connected to different light sources through the switching mechanism.
2Adaptability or versatility
If multiple reflector cups are used for multiple light sources, then various light source combinations can be achieved, but the device complexity increases
Solution Approach 1:
The light guiding part is designed as a universal component that can work with multiple light source emitting parts. This multi-functional design reduces the overall number of components needed compared to having dedicated reflector cups for each light source, thereby simplifying the device structure while maintaining the ability to create various light source combinations.
Solution Approach 2:
The patent introduces a dynamic switching mechanism that allows the light guiding part to be selectively connected to different light source emitting parts. This dynamic configuration enables various light source combinations without requiring multiple static reflector cups, reducing structural complexity while maintaining versatility.
