Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If laser marking is performed on the electrode plate during battery manufacturing, then the electrode plate can be identified for subsequent operations, but the position control of the laser mark is difficult leading to low precision
Solution Approach 1:
The patent applies the dynamics principle by making the laser assembly rotate synchronously with the electrode plate instead of keeping it stationary. The laser assembly is mounted on the rotating roller and rotates together with the electrode plate, allowing the laser beam to dynamically track the electrode plate's motion. This dynamic configuration enables precise position control of the laser mark by synchronizing the laser assembly's rotation with the electrode plate's rotation, directly resolving the position control difficulty while maintaining high marking precision.
2Productivity
If static laser marking is used on the electrode plate, then the marking can be performed, but the process is slow and requires frequent start-ups reducing production efficiency
Solution Approach 1:
The patent implements continuity of useful action by enabling continuous laser marking throughout the electrode plate's rotation. The laser assembly rotates synchronously with the electrode plate, allowing the laser beam to continuously mark the electrode plate surface without stopping or frequent start-ups. This continuous marking process eliminates the idle time and frequent start-stop operations characteristic of static marking methods, significantly improving both marking speed and production efficiency while maintaining marking quality.
