Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If separate fixing members such as bolts are used to assemble the circuit board and frame, then the structural strength is improved, but the assembly difficulty increases and manufacturing cost increases
Solution Approach 1:
The fixing means is integrated into the frame structure itself, merging the frame and fixing components into a single unified structure. This eliminates the need for separate bolts or fasteners, thereby reducing assembly steps while maintaining structural strength through the integrated design.
Solution Approach 2:
The frame's own structure provides the fixing function through integrated fixing means. The frame serves dual purposes: structural support and circuit board fixation, eliminating the need for external fixing members and simplifying the assembly process.

3Adaptability or versatility
If manual handling is used during assembly, then the flexibility is improved, but the risk of component damage increases
Solution Approach 1:
The expansion pin actuation mechanism serves as an intermediary tool that facilitates the assembly process. It applies controlled force to deform and restore the fixing means, enabling assembly while minimizing direct manual handling and reducing the risk of component damage.
Solution Approach 2:
The fixing means utilizes elastic deformation as a parameter change mechanism. By temporarily deforming the elastic fixing means during assembly and then restoring it, the system achieves secure fixation while controlling forces to prevent component damage.
