Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the number of connections between tube system and temperature-control elements is increased to improve temperature control coverage, then temperature control effectiveness is improved, but the number of leakage points increases and system reliability deteriorates
Solution Approach 1:
The patent combines multiple temperature control functions into a single integrated temperature control element that contacts multiple battery cells simultaneously. This merging approach reduces the total number of separate connections needed while maintaining comprehensive temperature control coverage, thereby reducing leakage points and improving system reliability.
Solution Approach 2:
The temperature control element is designed to serve multiple battery cells at once, performing universal temperature control across different cells through a single connection interface. This multi-functional design reduces the number of dedicated connections required while ensuring effective thermal management across the battery pack.
2Reliability
If complex connection technologies with multiple components (rapid-action connectors, supporting sleeves, clips) are used to ensure connection reliability, then connection reliability is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent extracts and eliminates unnecessary intermediate components from the connection system. By using a simplified direct connection approach between the temperature control element and battery cells, it removes rapid-action connectors, supporting sleeves, and clips while maintaining adequate connection reliability through proper structural design.
Solution Approach 2:
Instead of using multiple separate components to achieve connection (the conventional approach), the patent inverts the approach by using a single integrated structure that inherently provides both mechanical support and thermal contact, thereby simplifying the connection system while maintaining reliability.
3Reliability
If multiple separate connection components are used to ensure proper alignment and connection, then connection reliability is improved, but fitting time and manufacturing costs increase
Solution Approach 1:
The patent merges alignment and connection functions into a single integrated structure. The temperature control element is designed with built-in alignment features that guide proper positioning during installation, eliminating the need for separate alignment components and reducing fitting time while maintaining connection reliability.
4Reliability
If validated connection technologies with proven track records are used to reduce development risks, then system reliability is improved, but adaptability to different battery configurations is reduced
Solution Approach 1:
The temperature control element is designed with universal characteristics that allow it to adapt to different battery cell configurations and arrangements. The integrated design maintains proven reliability through validated thermal contact surfaces while accommodating variations in battery pack layouts through flexible mounting options and standardized connection interfaces.
