Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional mechanical die cutting process is used for electrode plate cutting, then the cutting process is simple, but the waste edge guiding is unsmooth causing shaking and bulging at laser-cutting point
Solution Approach 1:
A guiding mechanism with V-shaped guiding blocks is introduced as an intermediary between the mechanical die cutting and laser cutting processes. The V-shaped blocks smoothly guide the waste edge through the cutting area, preventing shaking and bulging that would otherwise occur at the laser-cutting point, thereby maintaining laser-cutting precision while keeping the overall process simple
Solution Approach 2:
The waste edge is pre-guided and stabilized by the guiding mechanism before reaching the laser-cutting point. This preliminary action of smooth guiding prevents shaking and bulging from occurring during laser cutting, ensuring the laser remains focused and cutting precision is maintained
2Manufacturing precision
If laser cutting process is used for electrode plate die cutting, then the cutting precision is improved, but shaking and bulging of waste edge causes laser defocus
Solution Approach 1:
The guiding mechanism acts as a mediator that stabilizes the waste edge before it reaches the laser-cutting zone. The V-shaped guiding blocks ensure smooth passage of the waste edge, preventing shaking and bulging that would cause laser defocus, thereby maintaining both cutting precision and laser focus stability
Solution Approach 2:
The guiding mechanism applies preliminary anti-action by counteracting any potential shaking or bulging of the waste edge before it can affect the laser-cutting process. This preventive measure ensures the waste edge remains stable and the laser maintains consistent focus throughout cutting
3Productivity
If waste edge is not properly guided, then the processing speed is fast, but shaking and bulging degrades power battery quality and performance
Solution Approach 1:
The guiding mechanism with V-shaped blocks is introduced as a minimal-interference intermediary that maintains fast processing speed while ensuring smooth waste edge guidance. The guiding structure prevents shaking and bulging without significantly slowing down the cutting process, thereby maintaining both productivity and power battery quality
