Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standard electrode plates are used for calibration, then calibration accuracy is ensured, but calibration time is excessively long due to production requirements
Solution Approach 1:
The standard electrode plate is segmented into a reusable support plate and multiple detachable standard zones. Each standard zone can be independently replaced, allowing calibration to be performed using only the standard zones rather than producing entire electrode plates. This segmentation enables rapid calibration while maintaining accuracy.
Solution Approach 2:
Instead of using actual electrode plates for calibration, the patent creates simplified copies in the form of standard zones mounted on support plates. These standard zones replicate the essential measurement characteristics without requiring the full production process of electrode plates, thus reducing calibration time while preserving measurement accuracy.
2Reliability
If standard electrode plates are produced for calibration, then accurate calibration standards are obtained, but production complexity and time consumption increase
Solution Approach 1:
The calibration standard is segmented into a support plate and separate standard zones. This allows the complex electrode plate production process to be replaced by simply mounting pre-made standard zones onto the support plate, significantly reducing calibration process complexity while maintaining standard accuracy.
Solution Approach 2:
Standard zones are prepared in advance and stored for reuse. During calibration, these pre-prepared standard zones are simply mounted onto the support plate without requiring any production processes, thereby eliminating the complexity of producing calibration standards while ensuring their accuracy is maintained.
3Measurement precision
If conventional calibration methods are used, then calibration standards are established, but calibration efficiency remains low due to repeated production requirements
Solution Approach 1:
The patent enables the support plate to be recovered and reused across multiple calibration operations. Only the standard zones need to be replaced when changing calibration standards, not the entire electrode plate. This recovery and reuse mechanism dramatically improves calibration efficiency while maintaining the ability to establish accurate calibration standards.
Solution Approach 2:
The support plate serves as a universal base that can accommodate different standard zones for various calibration requirements. This multi-functionality allows a single support plate to be used repeatedly for different calibration tasks, improving overall calibration efficiency while ensuring accurate standard establishment for each specific calibration need.

AI summary
Embodiments of this application provide a surface density device calibration apparatus and a surface density device calibration method, and relate to the field of battery testing devices. The surface density device calibration apparatus is configured to calibrate a surface density measurement device. The surface density device calibration apparatus includes a mounting bracket, a standard member, and an adjusting member. The mounting bracket is configured for mounting a surface density device. The standard member includes multiple standard zones with different densities. The adjusting member connects the standard member and the mounting bracket, and the adjusting member is configured to adjust positions of the multiple standard zones such that the multiple standard zones move one by one to a testing position of the surface density device. The standard member is used instead of an electrode plate for calibrating the surface density device, which reduces the production time of the electrode plate, and improves the calibration efficiency of the surface density device.
