Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera moves to capture terminal posts without predetermined distance, then the addressing system can adapt to different battery packs, but the positioning accuracy and addressing efficiency deteriorate due to inability to determine movement distance
Solution Approach 1:
The system performs preliminary action by obtaining product information including initial addressing coordinates of terminal posts before the camera movement. This allows the system to pre-calculate the movement distance and direction needed to capture each terminal post, ensuring accurate positioning without repeated adjustments.
Solution Approach 2:
The system uses feedback by comparing the initial addressing coordinates with the actual captured images. The addressing coordinates guide the camera movement, and the captured images provide feedback to verify successful capture, allowing for precise positioning adjustments if needed.
2Reliability
If the camera moves repeatedly to capture terminal posts, then the system can ensure terminal posts are captured, but the addressing efficiency deteriorates due to multiple movements and adjustments
Solution Approach 1:
The system calculates the movement distance and direction in advance based on the initial addressing coordinates obtained from product information. This preliminary calculation allows the camera to move directly to the correct position in a single action, ensuring reliable capture while maintaining high addressing efficiency.
Solution Approach 2:
The system uses the product information and initial addressing coordinates as self-service data that automatically guides the camera positioning. The system serves itself by using its own obtained data to determine the movement parameters, eliminating the need for repeated trial-and-error movements.
3Productivity
If the system uses initial addressing coordinates from product information, then the addressing efficiency improves, but the device complexity increases due to information retrieval and processing requirements
Solution Approach 1:
The system introduces an intermediary element - the product information database containing initial addressing coordinates. This intermediary stores the necessary positioning data, allowing the camera system to efficiently retrieve and use coordinates without complex real-time calculations or additional hardware components.

AI summary
Embodiments of the present disclosure provide a pre-welding addressing method and system. The pre-welding addressing method includes: obtaining product information of a to-be-addressed battery pack, in response to the battery pack getting in position, where the battery pack includes a plurality of cells, and the product information includes initial addressing coordinates of a plurality of cell terminal posts; obtaining positioning deviation values of the plurality of cell terminal posts based respectively on the initial addressing coordinates of the plurality of cell terminal posts, where the positioning deviation values of the cell terminal posts are determined based on addressing images of the cell terminal posts that are acquired by an addressing camera module; and determining target addressing coordinates of the plurality of cell terminal posts based respectively on the initial addressing coordinates of the plurality of cell terminal posts and the positioning deviation values of the plurality of cell terminal posts. As such, positions of the cell terminal posts in the battery pack can be addressed quickly and accurately based on the product information of the battery pack, increasing the addressing efficiency for the cell terminal posts.
