Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual installation of current breaking member is performed by skilled worker, then installation quality can be maintained, but product uniformity deteriorates and manufacturing cost increases
Solution Approach 1:
The patent replaces the manual mechanical installation process with an automated bending apparatus that uses a rotation driving unit and bending guide unit to precisely position and bend the current breaking member. This automation eliminates human variability while maintaining installation quality through consistent mechanical positioning and bending forces.
Solution Approach 2:
The patent changes the installation process from manual operation to automated control by adjusting parameters such as rotation angle, bending force, and positioning coordinates. The rotation driving unit controls the bending angle precisely, and the bending guide unit ensures consistent positioning, thereby improving product uniformity while maintaining installation quality.
2Ease of operation
If manual installation process is used, then flexibility in handling complex installations is maintained, but manufacturing cost increases and productivity decreases
Solution Approach 1:
The patent replaces manual installation operations with an automated system comprising a bending jig, rotation driving unit, and bending guide unit. This substitution increases productivity by eliminating manual labor bottlenecks while maintaining operational flexibility through programmable control of the bending process parameters.
Solution Approach 2:
The patent transforms the installation process from skill-dependent manual operation to parameter-controlled automation. By adjusting rotation angles, bending forces, and positioning parameters, the system maintains handling flexibility for different installation scenarios while significantly increasing manufacturing efficiency and reducing costs.
3Adaptability or versatility
If current breaking member is installed manually, then adaptation to different battery configurations is possible, but safety risks increase due to potential short circuits
Solution Approach 1:
The patent replaces manual installation with an automated bending apparatus that precisely positions the current breaking member relative to the electrode lead. This substitution eliminates safety risks associated with manual handling and short circuit creation while maintaining adaptability through programmable positioning and bending parameters that can accommodate different battery configurations.
Solution Approach 2:
The patent uses parameter control to achieve both safety and adaptability. By precisely controlling rotation angles, bending forces, and positioning coordinates, the system ensures safe installation that prevents short circuits while maintaining the ability to adapt to different battery pack configurations through parameter adjustment.
4Manufacturing precision
If automated bending apparatus is implemented, then product uniformity and safety are improved, but device complexity increases
Solution Approach 1:
The patent divides the automated bending apparatus into distinct functional modules: a bending jig for holding the current breaking member, a rotation driving unit for controlled rotation, and a bending guide unit for precise positioning. This segmentation manages device complexity by creating modular, independently controllable components while achieving high product uniformity through their coordinated operation.
Solution Approach 2:
The patent designs the bending apparatus with multi-functional components that perform multiple operations. The rotation driving unit simultaneously controls rotation and positioning, while the bending guide unit integrates positioning and bending guidance functions. This universality reduces overall device complexity while maintaining manufacturing precision and product uniformity.
