Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the partial region of the separator is cut according to the related art, then the separator shape corresponds to the electrode shape, but the number of separators that can be properly cut is limited and excessive equipment and manufacturing time are required
Solution Approach 1:
The invention forms a pre-sealing part by attaching partial regions of the plurality of separators to each other before cutting. This preliminary attachment action enables multiple separators to be cut simultaneously while maintaining proper cutting quality, thereby resolving the contradiction between cutting precision and manufacturing efficiency
Solution Approach 2:
The invention merges multiple separators by attaching their partial regions together to form a pre-sealing part. This merging allows the separators to be handled and cut as a unified structure, enabling simultaneous cutting of multiple separators and significantly improving productivity while maintaining cutting quality
2Quantity of substance
If a large number of electrode units are manufactured using the related art method, then the electrode assembly can be produced, but excessive equipment and manufacturing time are required
Solution Approach 1:
By merging multiple separators into a pre-sealing part structure, the invention enables batch processing of multiple electrode units. This reduces the need for excessive equipment and manufacturing time when producing large quantities of electrode assemblies
Solution Approach 2:
The preliminary formation of pre-sealing parts before cutting enables subsequent batch cutting operations. This preliminary action simplifies the manufacturing process for large quantities of electrode units, reducing both equipment complexity and manufacturing time
3Shape
If the partial region of the separator is cut according to the related art, then the separator shape corresponds to the electrode shape, but the manufacturing process becomes complex and time-consuming
Solution Approach 1:
The invention performs the attachment of partial regions of separators as a preliminary action before cutting. This sequence enables the separators to maintain proper shape correspondence while being cut more efficiently, reducing manufacturing time without compromising shape accuracy
Solution Approach 2:
By merging multiple separators into a pre-sealing part, the invention enables simultaneous cutting operations that maintain shape correspondence. This approach significantly reduces the time required compared to cutting separators individually while ensuring proper shape matching with electrodes
