Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If plate-like heat sinks without heat dissipation fins are used, then the device structure is simplified, but the heat sinks cannot be neatly stacked due to projecting peripheries and stepped configurations
Solution Approach 1:
The heat sink periphery is segmented into multiple sections, with each section having a different height to form stepped portions. This segmentation allows the heat sink to be neatly stacked with other identical heat sinks while maintaining the simplified plate-like structure without heat dissipation fins.
2Volume of moving object
If heat sinks are stacked in a stepped fashion for storage, then storage space is saved, but the heat sinks become inclined and cannot be correctly stacked
Solution Approach 1:
The heat sink employs asymmetric design with stepped portions at specific locations on the periphery. This asymmetric configuration creates a unique stacking orientation that prevents heat sinks from being stacked in incorrect orientations, ensuring proper alignment while maintaining compact storage.
3Reliability
If engaging projections are provided on the circuit board, then the rectifying device is securely fixed to the case, but the device complexity increases
Solution Approach 1:
The engaging projections are integrated directly into the circuit board structure, merging the fixation function with the existing circuit board components. This eliminates the need for separate fixation mechanisms, reducing overall device complexity while maintaining secure attachment of the rectifying device to the case.
