Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional fixing device with separate components (fixing component and compression spring) is used, then the heat dissipating component can be fixed on the main board, but the assembly process becomes complicated and difficult to achieve preferred yield rate
Solution Approach 1:
The patent combines the fixing component and compression spring into a single integrated unit. The fixing component includes an engaging portion with external threads that can be screwed into the supporter, while the compression spring is pre-installed within the fixing component's hollow structure. This merging eliminates the need for separate assembly of multiple components, simplifying the overall structure and improving assembly reliability.
Solution Approach 2:
The fixing component is segmented into functional portions: a body portion housing the compression spring, an engaging portion with external threads for securing to the supporter, and a pressing portion that contacts the heat dissipating component. This segmentation allows each portion to perform its specific function efficiently while maintaining an integrated structure that is easier to manufacture and assemble.
2Strength
If multiple separate components (fixing component, compression spring, bridging component) are used, then the heat dissipating component can be securely fixed, but the assembly operation becomes inconvenient and time-consuming
Solution Approach 1:
The fixing component integrates the compression spring, engaging portion, and pressing portion into a single unit. The compression spring is pre-installed within the hollow body of the fixing component, and the engaging portion with external threads is formed as an integral part. This reduces the number of assembly steps from assembling multiple separate components to simply screwing the integrated fixing component into the supporter.
3Reliability
If a conventional fixing device with multiple components is used, then the heat dissipating component can be fixed against the heat generating component, but the disassembly process becomes complicated
Solution Approach 1:
The fixing component is designed as an integrated unit with the compression spring and engaging portion formed as one piece. This integration simplifies disassembly because the entire fixing component can be removed as a single unit by unscrewing the engaging portion from the supporter, eliminating the need to disassemble and reassemble multiple separate components.
