Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the heat-dissipating plate is bent to dissipate heat for multiple surfaces, then the heat dissipation coverage is improved, but the structural strength deteriorates causing local deformation and fracture
Solution Approach 1:
The harmonica-shaped tube is nested within the transition section of the heat-dissipating plate, with the tube's walls forming reinforcing ribs that are integrated into the plate structure. This nested arrangement allows the tube to provide internal reinforcement without adding external bulk, strengthening the bend area while maintaining the plate's ability to conform to multiple surfaces for enhanced heat dissipation coverage
Solution Approach 2:
The transition section combines the heat-dissipating plate material with the harmonica-shaped tube material to create a composite structure. The tube's rigid walls provide structural reinforcement at the vulnerable bend area, while the plate material maintains thermal conductivity, creating a composite that simultaneously improves strength and preserves heat dissipation functionality
2Adaptability or versatility
If the heat-dissipating plate is bent, then the adaptability to multiple surfaces is improved, but the manufacturing precision deteriorates due to stress concentration
Solution Approach 1:
The harmonica-shaped tube is pre-installed within the transition section before the bending process. The tube's rigid structure serves as a preliminary reinforcement that prevents deformation during bending, ensuring that the final geometry maintains precise dimensions and proper channel alignment even after the plate is formed to match multiple surfaces
Solution Approach 2:
The harmonica-shaped tube acts as an intermediary element between the conflicting requirements of plate flexibility and dimensional precision. The tube mediates the bending process by providing internal support that allows the plate to adapt to multiple surfaces while maintaining precise dimensional control of the cooling channels and transition section geometry
3Strength
If the transition section is reinforced, then the structural strength is improved, but the device complexity increases
Solution Approach 1:
The harmonica-shaped tube serves multiple functions simultaneously: it reinforces the transition section structurally, defines the cooling channel geometry, and provides flow guidance. This multi-functionality allows the structure to achieve enhanced strength without adding separate reinforcement components, thereby avoiding increased device complexity while still improving structural integrity

Function Achieved in This Case
The solution strengthens the heat-dissipating member's structural integrity at bends, preventing local deformation or fracture, and maintains effective heat dissipation by ensuring smooth flow through the liquid inlet and outlet channels, even under stress.
Implementation Method 1
Each of the two harmonica-shaped tubes defines a flow channel cavity. The flow channel cavity of one of the two harmonica-shaped tubes positioned in the liquid inlet channel is in communication with the liquid inlet channel, and the flow channel cavity of the other one of the two harmonica-shaped tubes positioned in the liquid outlet channel is in communication with the liquid outlet channel.
Implementation Method 2
The heat-dissipating plate is attached to an outer surface of the cell module and is configured to dissipate heat for the cell module
