Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional assembly process is used, then assembly is possible, but assembly process is complex and time-consuming
Solution Approach 1:
The optical portion is divided into modular components with separate first and second snap-fit elements, allowing independent assembly of circuit board and light source board. This segmentation enables parallel assembly operations and simplifies the overall assembly process while maintaining structural integrity.
Solution Approach 2:
The snap-fit elements integrate multiple functions: mechanical connection, positioning, and heat dissipation guidance. The first snap-fit element simultaneously connects the circuit board to the optical portion and provides a mounting structure for the light source board, reducing the number of separate assembly steps.
2Temperature
If traditional assembly process is used, then assembly is possible, but heat dissipation is poor
Solution Approach 1:
Heat dissipation holes are strategically positioned at specific locations on the circuit board and optical portion to maximize thermal transfer efficiency. The snap-fit elements are designed with specific geometric features that create thermal pathways, concentrating heat dissipation capabilities at critical locations rather than distributing them uniformly.
Solution Approach 2:
The light source board is nested between the optical portion and circuit board, with the first snap-fit element passing through the light source board. This nested structure creates multiple thermal contact interfaces and pathways, enhancing heat dissipation through layered thermal conduction while maintaining a compact overall structure.
