Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods are used to stack and connect lithium rechargeable batteries, then the structure is simpler, but the connection becomes insecure and unstable
Solution Approach 1:
The battery stack is divided into multiple independent battery units, each with its own supporting structure and connecting mechanism. This segmentation allows for individual stabilization of each battery while maintaining overall system reliability through modular design.
Solution Approach 2:
The patent implements pre-positioned supporting structures and connecting mechanisms that are prepared in advance within the stack frame. These preliminary structures ensure that batteries are securely held and properly connected before operation begins, preventing instability during charge/discharge cycles.
2Temperature
If conventional connection methods are used, then fewer components are needed, but heat management becomes ineffective leading to overheating
Solution Approach 1:
The patent incorporates localized ventilation paths and heat dissipation structures at specific locations within the battery stack where heat generation is most intense. This targeted approach improves thermal management effectiveness without requiring a complete redesign of the entire stack structure.
Solution Approach 2:
The patent introduces ventilation paths and cooling structures as intermediary elements between the battery units and the external environment. These intermediaries facilitate heat transfer and dissipation, acting as a bridge between the heat-generating batteries and the cooling system.
3Adaptability or versatility
If batteries are connected without external devices, then the device complexity is reduced, but the ease of operation for voltage and capacity adjustment is limited
Solution Approach 1:
The patent implements a dynamic connection structure that allows batteries to be reconfigured between series and parallel connections. This dynamic design enables voltage and capacity adjustments by changing the electrical configuration of the battery stack without requiring external connection devices, maintaining adaptability while simplifying the overall system.
