Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fasteners (screw with tapered ring and sealing ring) are used to secure heatsink to load frame, then the heatsink can be attached, but the structure becomes complex and may damage the fastener or load frame structure
Solution Approach 1:
The fastener is divided into separate functional components: a reusable holding component with pins for positioning and attachment, and a separate fastener element. This segmentation simplifies the overall structure while maintaining secure attachment, as each component performs its specific function without requiring complex integration of multiple elements into a single fastener assembly
Solution Approach 2:
The tapered ring and sealing ring are extracted from the conventional fastener design and replaced with a simplified pin-based holding component. This extraction removes unnecessary structural complexity while preserving the essential attachment function, allowing the heatsink to be securely mounted without the cumbersome multi-element fastener structure
2Ease of operation
If conventional fasteners are used to secure heatsink, then attachment is achieved, but multiple steps are required and structural damage may occur
Solution Approach 1:
The holding component with pins is pre-installed on the heatsink before mounting to the load frame. This preliminary action positions the heatsink correctly and prepares the attachment points in advance, so that when the fastener element is inserted, the attachment is completed in a single straightforward operation without requiring multiple adjustment steps
Solution Approach 2:
The pin-based holding component automatically positions and secures the heatsink through its own structural design, without requiring external alignment tools or multiple fastening operations. The pins engage with corresponding features on the load frame, creating a self-aligning, self-securing mechanism that reduces both operational complexity and time
3Strength
If conventional fasteners are used, then heatsink can be secured, but the fastener or load frame structure may be destroyed
Solution Approach 1:
The holding component uses flexible pins that can elastically deform during insertion and engagement. This flexibility allows the pins to accommodate minor misalignments and variations in the load frame structure without generating excessive stress that could damage either the fastener or the frame, while still maintaining strong attachment when engaged
Solution Approach 2:
The pin design incorporates inherent cushioning through its structural geometry and material properties, which absorb and distribute attachment forces evenly. This beforehand cushioning prevents stress concentration that could lead to structural damage, protecting both the fastener component and the load frame from harmful forces during the attachment process
