Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed imaging angle is used for battery inspection, then the device structure is simple, but internal structures such as tabs are occluded and imaging is unclear
Solution Approach 1:
The patent applies the dynamics principle by making the supporting component rotatable around the battery, allowing the imaging angle to be dynamically adjusted. The rotation mechanism enables the supporting component to move from a fixed position to multiple angular positions, transforming the static imaging system into a dynamic one that can adapt different angles to reduce occlusion of internal structures like tabs and achieve clearer imaging.
2Measurement precision
If the supporting component is rotated to adjust imaging angle, then occlusion of internal structures is reduced, but the device complexity increases
Solution Approach 1:
The supporting component serves multiple functions: it not only supports the battery but also acts as the rotating element to adjust the imaging angle. By integrating the rotation function into the supporting component itself, the patent reduces the need for separate adjustment mechanisms, thereby managing device complexity while achieving improved defect detection accuracy through angle adjustment.
3Productivity
If automated defect inspection is implemented, then inspection efficiency is improved, but the system complexity increases
Solution Approach 1:
The defect inspection unit is configured to automatically perform defect inspection based on images obtained from the detector. The system implements self-service by having the inspection unit autonomously analyze the captured images without requiring manual intervention, thereby improving inspection efficiency while managing system complexity through automation of the inspection process.

Data Source
AI summary
A battery defect inspection device, method, and apparatus are disclosed. The battery defect inspection device includes a ray source, a detector, and a supporting component between the ray source and the detector. A battery under inspection is configured to be located on a supporting surface of the supporting component. The battery defect inspection device further includes a rotation mechanism. The rotation mechanism is configured to rotate the supporting component along a preset rotation axis, or is configured to rotate the ray source and the detector about a preset rotation axis, such that the optical axis of the rays emitted from the ray source is projected obliquely onto a surface of the battery under inspection. At least an included angle between an end surface of the battery under inspection and a plane on which the detector is located can be flexibly adjusted according to the needs of different inspection scenarios.
