Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a diffusing portion or reflecting portion is coupled with the LED array to adjust light brightness and distribution angle, then the light output characteristics are improved, but the structural complexity and coupling difficulty increase
Solution Approach 1:
The patent divides the lighting module into separable components: the LED array and the diffusing/reflecting portions are independent modules that can be coupled or separated. The coupling structure includes protrusions on one component and corresponding insertion members on the other, enabling modular assembly and disassembly while maintaining simple individual component designs
Solution Approach 2:
The coupling structure is designed to be universal, allowing the same protrusion-insertion member mechanism to accommodate both diffusing portions and reflecting portions. This multi-functional coupling design enables the LED array to work with different optical components using a standardized interface, reducing overall system complexity
2Illumination intensity
If a diffusing portion or reflecting portion is coupled with the LED array to adjust light distribution angle, then the light distribution characteristics are improved, but the assembly and replacement difficulty increase
Solution Approach 1:
The module is segmented into independently coupleable parts with simple coupling interfaces. The protrusions and insertion members create a snap-fit or slide-fit connection that requires minimal assembly steps, allowing users to easily assemble or replace the diffusing/reflecting portions without complex tools or procedures
Solution Approach 2:
The coupling structure incorporates dynamic elements such as elastic deformation of the insertion members or movable protrusions that facilitate easy insertion and removal. The design allows for tolerant alignment during assembly and secure locking once coupled, making the operation simple and quick
