Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gas is removed after disposing a battery cell in a separately manufactured chamber, then gas removal can be performed, but productivity becomes significantly low
Solution Approach 1:
The patent merges the gas removal function with the battery cell manufacturing process by integrating a gas suction portion directly into the manufacturing apparatus. The suction ports are formed within the manufacturing equipment itself, allowing gas removal to occur concurrently with manufacturing operations, thereby eliminating the need for separate degassing chambers and significantly improving productivity.
Solution Approach 2:
The patent extracts the gas removal function from the separate chamber approach and integrates it directly into the manufacturing process through suction ports positioned within the manufacturing apparatus. This extraction of the gas removal step from a separate process allows it to be performed inline during manufacturing, improving efficiency without requiring additional standalone equipment.
2Object-affected harmful factors
If a separate chamber is used for gas removal, then gas can be removed from battery cells, but facility size increases
Solution Approach 1:
The patent combines the gas removal function with the existing manufacturing facility by integrating suction ports into the manufacturing apparatus. This merging eliminates the need for separate degassing chambers, thereby removing the harmful gas accumulation issue while avoiding any increase in facility size.
3Object-affected harmful factors
If a separate chamber is used for gas removal, then gas removal can be performed, but process time increases
Solution Approach 1:
The patent implements preliminary gas removal action by positioning suction ports within the manufacturing apparatus to extract gas during the manufacturing process itself, before the battery cells would otherwise require separate post-processing. This preliminary action eliminates the need for subsequent dedicated degassing steps, significantly reducing total process time.
Solution Approach 2:
The patent enables continuous gas removal during the manufacturing process through integrated suction ports, maintaining continuous useful action throughout production. Gas is removed continuously as cells are manufactured rather than requiring interruption for separate batch processing, thereby minimizing loss of time and improving overall process efficiency.
