Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the main body part is bent to form multiple connecting regions to increase heat exchange area, then heat exchange efficiency is improved, but the corner region experiences significant tension that may cause breaking or collapsing
Solution Approach 1:
The main body part is segmented into multiple connecting regions that are bent to form corner regions, allowing the structure to adapt to battery cell arrangements while maintaining heat exchange efficiency. The segmentation enables flexible positioning of medium channels at corners to maximize contact with battery cells.
Solution Approach 2:
A shielding member is pre-installed at the corner region to compensate for the tension and stress concentration that occurs during bending. This shielding member reinforces the corner region before it undergoes operational stresses, preventing breaking or collapsing and ensuring structural integrity.
2Reliability
If a shielding member is added to seal the opening and relieve tension at the corner region, then structural reliability is improved, but device complexity increases
Solution Approach 1:
The shielding member is integrated with the main body part through connection structures, merging the reinforcement function with the existing thermal management structure. This combination approach adds minimal complexity while providing essential structural support at the corner region.
3Reliability
If medium channel passes through corner region to maximize heat exchange area, then heat exchange efficiency is improved, but manufacturing precision requirements increase due to bending tensions
Solution Approach 1:
The medium channel is pre-formed within the main body part before the bending process. This preliminary formation ensures that the channel maintains its structural integrity and precise positioning throughout the bending operation, reducing manufacturing defects and ensuring accurate placement at corner regions for optimal heat exchange.
