Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cell frames are used to secure battery cells, then the battery cells are well-supported, but the manufacturing cost and device complexity increase
Solution Approach 1:
The patent combines multiple cell frames into a single integrated cell frame structure that can securely hold multiple battery cells. This unified frame eliminates the need for separate frames for each cell while maintaining adequate support and spacing for all cells, thereby reducing component count and manufacturing complexity while preserving structural reliability.
2Reliability
If multiple cell frames are used to secure battery cells, then the battery cells are well-supported, but manufacturing cost increases
Solution Approach 1:
By merging multiple cell frames into one integrated structure, the patent reduces the total number of components that need to be manufactured, procured, and assembled. This consolidation directly lowers material costs, manufacturing overhead, and assembly labor while maintaining the necessary support functionality for all battery cells.
3Ease of operation
If conventional cell frames are used, then battery cells can be received, but cell movement occurs leading to shorts and reduced durability
Solution Approach 1:
The single cell frame is segmented into multiple compartments or sections, each designed to receive and securely position individual battery cells. These segmented sections include positioning features such as ribs, grooves, or protrusions that prevent cell movement in various directions, thereby maintaining cell stability while enabling efficient cell reception.
4Device complexity
If a single cell frame is used, then manufacturing cost and complexity are reduced, but cell movement prevention must be ensured
Solution Approach 1:
The single cell frame is designed with multi-functional features that simultaneously achieve cell reception, positioning, and movement prevention. The frame incorporates integrated spacing elements, securing mechanisms, and alignment features that perform multiple functions within a single structure, eliminating the need for additional components while ensuring reliable cell stabilization.
