Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high manufacturing precision is required for connecting heat dissipation elements with hash boards, then contact tightness is improved, but manufacturing complexity and difficulty increase
Solution Approach 1:
The heat dissipation assembly is segmented into a plate body and multiple protruding ribs, where the ribs are distributed across the plate surface to contact different regions of the hash board. This segmentation allows each rib to independently ensure contact tightness without requiring the entire assembly to be manufactured with high precision, thereby reducing manufacturing complexity while maintaining contact quality.
Solution Approach 2:
The ribs are strategically positioned to contact specific local regions of the hash board where heat dissipation is most critical. By concentrating contact functionality at these local points rather than requiring uniform contact across the entire surface, the design achieves effective heat dissipation with relaxed overall manufacturing precision requirements.
2Manufacturing precision
If high manufacturing precision is required for connecting heat dissipation elements with hash boards, then contact uniformity is improved, but ease of manufacture deteriorates
Solution Approach 1:
The contact interface is segmented into multiple discrete rib-hash board contact points rather than requiring a single large-scale precise interface. Each rib can be manufactured and positioned independently, making it easier to achieve uniform contact distribution across the hash board surface without requiring extremely high overall manufacturing precision.
Solution Approach 2:
The ribs are pre-formed as integral protrusions from the plate body during manufacturing, establishing the contact geometry in advance. This preliminary formation of contact structures simplifies the assembly process and ensures consistent contact uniformity without requiring complex post-manufacturing adjustments or high-precision fitting operations.
3Ease of manufacture
If traditional connection methods are used, then manufacturing simplicity is maintained, but heat dissipation efficiency deteriorates due to low contact quality
Solution Approach 1:
The ribs are designed with curved or rounded contact surfaces rather than flat planes, allowing them to conform to the hash board surface topology. This curvature enables better contact adaptation and tighter thermal coupling without requiring high manufacturing precision, thereby maintaining manufacturing simplicity while significantly improving heat dissipation efficiency.
Solution Approach 2:
The design transitions from a two-dimensional planar contact interface to a three-dimensional structure with vertically protruding ribs. This dimensional change creates multiple contact points at different heights and positions, enhancing thermal contact quality and heat dissipation efficiency while keeping the overall manufacturing process relatively simple.
