Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires are exposed for electrical connection, then electrical connectivity is achieved, but safety deteriorates due to power leakage risk
Solution Approach 1:
The patent introduces an insulation plate as an intermediary component between the exposed wires and the external environment. This insulation plate covers the end surface of the rigid frame where wires are exposed, providing electrical isolation and preventing power leakage while maintaining electrical connectivity through proper wire routing and connection points.
2Strength
If rigid frame structure is used to protect cells, then mechanical strength is improved, but device complexity increases
Solution Approach 1:
The rigid frame is segmented into modular components with standardized connection interfaces. The frame consists of multiple bars connected through detachable joints, allowing the structure to be assembled from simple standardized parts rather than requiring a complex monolithic design. This segmentation maintains mechanical strength while reducing overall structural complexity.
Solution Approach 2:
The rigid frame structure serves multiple functions simultaneously: it provides mechanical support and protection for cells, acts as a mounting structure for insulation plates, and offers a standardized framework for wire routing. This multi-functionality reduces the need for additional separate components, thereby reducing device complexity while maintaining protective capabilities.
3Ease of manufacture
If detachable connection between frame bars is used, then ease of manufacture is improved, but reliability deteriorates due to connection stability
Solution Approach 1:
The detachable connection mechanism incorporates self-aligning and self-locking features that allow the frame bars to automatically position and secure themselves during assembly. The connection structure includes built-in positioning elements and locking mechanisms that ensure stable connections without requiring complex external tools or procedures, thereby maintaining both ease of manufacture and connection reliability.
