Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If standardized devices are used for manufacturing battery cells, then device complexity is reduced, but adaptability to various battery shapes and sizes deteriorates
Solution Approach 1:
The die assembly incorporates adjustable mold assemblies that can be repositioned along the base plate to change the dimensions of the inward recess. This dynamic adjustment capability allows a single standardized device to adapt to various battery cell shapes and sizes without requiring multiple specialized devices, thus maintaining low device complexity while achieving high adaptability.
Solution Approach 2:
The jig device is designed as a universal manufacturing device that can process multiple types of battery cells through the adjustable die assembly. The base plate with movable mold assemblies enables one device to perform multiple functions for different battery configurations, eliminating the need for separate standardized devices for each battery type.
2Adaptability or versatility
If separate manufacturing devices are created for various battery shapes, then adaptability improves, but device complexity and space requirements worsen
Solution Approach 1:
Instead of creating multiple static devices for different battery shapes, the invention employs a single dynamic device with adjustable mold assemblies that can be repositioned to match various battery configurations. This reduces device complexity while maintaining adaptability to diverse battery shapes and sizes.
Solution Approach 2:
The invention merges the functionality of multiple separate manufacturing devices into a single integrated jig device. The base plate combines multiple mold assemblies that can be arranged in different configurations, effectively combining what would otherwise require multiple separate devices into one unified system.
3Adaptability or versatility
If separate manufacturing devices are created for various battery shapes, then adaptability improves, but space requirements worsen
Solution Approach 1:
The invention consolidates multiple device functions into a single jig device with a base plate that accommodates adjustable mold assemblies. This merging approach significantly reduces the total space required compared to having separate manufacturing devices for each battery type, while still providing adaptability to various battery shapes and sizes.
Solution Approach 2:
The universal jig device performs multiple manufacturing functions for different battery configurations within a single compact unit. The base plate with repositionable mold assemblies enables one device to replace multiple specialized devices, thereby reducing the overall space footprint while maintaining full adaptability.
4Adaptability or versatility
If additional jig devices are manufactured for various battery shapes, then adaptability improves, but manufacturing time and cost worsen
Solution Approach 1:
The universal jig device with adjustable mold assemblies eliminates the need to manufacture separate jig devices for different battery shapes. A single device can be reconfigured for various battery types, saving the time and resources that would otherwise be required to produce multiple specialized jig devices while maintaining full adaptability.
Solution Approach 2:
The dynamic adjustability of the mold assemblies allows rapid reconfiguration for different battery shapes without requiring new device manufacturing. This eliminates the time loss associated with producing additional jig devices while preserving adaptability to various battery configurations.
