Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sampling part is directly installed on the battery cell surface, then the installation process is simple, but the sampling part cannot be securely fastened on non-planar or inclined surfaces, leading to instability and potential falling off
Solution Approach 1:
The patent introduces a support part as an intermediary component between the battery cell and the sampling part. The support part includes a support body with a first contact surface that contacts the battery cell and a second contact surface that supports the sampling part. This intermediary structure enables secure mounting of the sampling part on non-planar or inclined battery cell surfaces, resolving the contradiction between installation simplicity and sampling stability.
2Reliability
If the support part is made taller to improve sampling stability, then the sampling stability improves, but the support part protrudes from the battery cell and affects assembling of other components
Solution Approach 1:
The patent optimizes the height parameter of the support part to balance sampling stability and assembly compatibility. The support part's height is controlled to ensure the sampling part remains stable while preventing excessive protrusion that would interfere with other battery components. This parameter optimization resolves the contradiction between sampling stability and assembling complexity.
3Reliability
If the support part is attached to the battery cell, then the sampling part is securely fastened, but the contact area on non-planar surfaces is reduced, decreasing attachment strength
Solution Approach 1:
The patent designs the first contact surface of the support part with a curved or adaptive geometry that conforms to the non-planar or inclined surface of the battery cell. This curved surface design increases the effective contact area between the support part and the battery cell, thereby enhancing attachment strength despite the uneven surface, and resolving the contradiction between attachment strength and contact area.
