Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single cutter assembly moving along one direction is used, then the device complexity is reduced, but the cutting precision and adaptability to different battery orientations deteriorate
Solution Approach 1:
The cutting device is divided into multiple independent cutter assemblies (first cutter assembly and second cutter assembly), each capable of moving along different directions (first direction and second direction perpendicular to the first). This segmentation allows precise positioning and cutting from multiple angles, thereby improving cutting precision without requiring a single complex multi-functional assembly.
Solution Approach 2:
The patent introduces movement in a second direction that is perpendicular to the first direction of movement. This dimensional expansion allows the cutter assemblies to approach and cut the battery from different spatial orientations, enhancing adaptability to various battery positions and orientations while maintaining manageable device complexity through modular design.
2Productivity
If traditional cutting methods are used, then the device structure is simple, but the cutting speed and efficiency deteriorate
Solution Approach 1:
The pressing and cutting cutter assembly is configured to press and break the housing of the battery before the cutter blade makes contact with the battery components. This preliminary action of breaking the housing opens access to internal components and facilitates faster cutting operations, thereby improving cutting speed without requiring overly complex device structures.
Solution Approach 2:
The patent employs a pressing and cutting cutter assembly that changes the operational parameters by applying mechanical pressure to break the housing, transitioning from a simple cutting action to a two-stage process involving pressing/breaking followed by cutting. This parameter change enables faster access and cutting of battery components, enhancing productivity while maintaining reasonable device complexity.
3Productivity
If pressing and cutting cutter assembly is used to break the housing, then the cutting efficiency is improved, but the risk of harmful factors (battery leakage, short circuit) increases
Solution Approach 1:
The pressing and cutting cutter assembly is designed to control and utilize the breaking of the battery housing in a controlled manner. By applying pressure to break the housing systematically, the system converts the potentially harmful uncontrolled breaking into a beneficial process that facilitates efficient access to battery components for cutting, while the structured approach minimizes risks of leakage and short circuits.
4Adaptability or versatility
If multiple cutter assemblies moving in different directions are used, then the adaptability to different battery positions is improved, but the device complexity increases
Solution Approach 1:
Each cutter assembly is designed with multi-functionality, capable of moving along different directions (first and second perpendicular directions) and performing both pressing/breaking and cutting operations. This universal design allows a single cutter assembly to adapt to various battery positions and orientations, reducing the need for multiple specialized assemblies and thereby managing device complexity while maintaining high adaptability.
