Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the chip is fixed through a wiring harness in a battery, then the chip can monitor internal status changes, but the chip becomes easily loosened and separated
Solution Approach 1:
The insulating plate is segmented to include a dedicated chip embedding hole, separating the chip mounting function from the wiring harness connection. This segmentation allows the chip to be embedded in a fixed position on the insulating plate, eliminating the loosening issue while maintaining monitoring functionality.
Solution Approach 2:
The chip is nested within the chip embedding hole of the insulating plate, creating a nested structure where the chip is housed inside a dedicated cavity. This nesting provides secure positioning and prevents loosening, while the insulating plate itself is nested in the battery assembly.
2Reliability
If the chip is embedded in the insulating plate with a chip fixing buckle, then the connection becomes tighter and more stable, but the structure becomes more complex
Solution Approach 1:
The chip fixing buckle is merged with the insulating plate as an integrated component rather than a separate part. The buckle is formed directly on the insulating plate to engage with the chip, combining two functions (insulation and chip fixing) into one component, thereby reducing overall assembly complexity while improving reliability.
3Stability of the object's composition
If the chip embedding hole is provided on the insulating plate, then the structure compactness is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The chip embedding hole is designed with optimized dimensional parameters (depth, diameter, position) that balance structural integration needs with manufacturing capabilities. By carefully selecting these parameters, the design achieves good structural compactness while remaining feasible for standard manufacturing processes.
