Solution Approach 1:

The patent applies the dynamics principle by transitioning from a stationary detection system to a dynamic moving detection system. The detection device is mounted on a moving carriage that travels along the battery cell, allowing the detector to move synchronously with the conveyor belt. This enables the battery cell to remain stationary during detection while the detector moves, thereby maintaining detection accuracy while improving scanning efficiency through continuous motion-based detection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies segmentation by dividing the detection process into multiple detection regions along the battery cell length. Multiple detectors are arranged at different positions, and the detection process is divided into sequential segments as the carriage moves along the cell. This allows parallel detection of different sections while maintaining the stationary state of the battery cell, thus improving overall scanning efficiency without compromising detection accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 1:

The patent implements continuity of useful action by enabling continuous detection throughout the entire battery cell length. The moving carriage with multiple detectors continuously scans the battery cell as it passes through the detection zone, eliminating idle time between detection segments. This continuous detection process maintains high detection quality while significantly improving production efficiency by reducing detection time and enabling faster throughput.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The dynamic moving detection system allows the detection process to adapt to the production line speed. The carriage can move at variable speeds synchronized with the conveyor belt, enabling the system to maintain optimal detection quality while adjusting to different production rates. This dynamic capability resolves the contradiction between detection quality and production efficiency by allowing flexible operation at different speeds.

Principle #15Dynamics
