Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If components are densely arranged to reduce size, then miniaturization is achieved, but heat dissipation efficiency deteriorates
Solution Approach 1:
The internal space is partitioned into multiple distinct regions using partition walls, with each region dedicated to specific components (inductor, capacitor, semiconductor). This segmentation allows each component to be positioned optimally for heat dissipation while maintaining compact overall dimensions, resolving the contradiction between miniaturization and heat dissipation efficiency.
2Temperature
If separate flow paths are provided for heat dissipation, then cooling efficiency is improved, but device complexity increases
Solution Approach 1:
The cooling plate serves multiple functions simultaneously: it acts as a thermal management component with embedded flow paths for heat dissipation, a structural support element, and a space partitioning component. This multi-functionality improves cooling efficiency while avoiding the complexity increase that would result from adding separate, dedicated cooling structures.
Solution Approach 2:
The flow path is integrated directly into the cooling plate structure, merging the cooling function with the structural support function. This integration eliminates the need for separate cooling channels or additional components, thereby improving heat dissipation efficiency without increasing device complexity.
3Temperature
If components are located adjacent to flow paths for effective heat dissipation, then cooling efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
Partition walls are installed during assembly to pre-establish dedicated spaces for each component. This preliminary action guides component placement and ensures that inductors, capacitors, and semiconductors are positioned in thermally optimal locations adjacent to cooling flow paths, thereby achieving effective heat dissipation while reducing the stringency of manufacturing precision requirements.
4Volume of moving object
If dead space is eliminated for miniaturization, then size is reduced, but design freedom deteriorates
Solution Approach 1:
The partition walls extend in the vertical dimension to create stacked arrangements of components, allowing efficient use of three-dimensional space. This vertical dimension utilization enables compact miniaturization while maintaining design freedom, as components can be arranged in multiple layers rather than being constrained to a single horizontal plane.
