Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single electrochemical cell is reused for multiple tests with different electrode catalysts and conditions, then device complexity is reduced, but contamination occurs between tests and search range is limited
Solution Approach 1:
The patent divides the cell chamber into multiple independent regions (first chamber region and second chamber region) separated by a partition. Each region can accommodate different electrode catalysts and perform different electrochemical reactions simultaneously, preventing contamination between tests while maintaining a single cell structure.
Solution Approach 2:
The single electrochemical cell is designed to perform multiple functions by accommodating different types of electrode catalysts (first electrode catalyst and second electrode catalyst) in different chamber regions. This multi-functional design allows the cell to screen various electrode catalysts and reaction conditions without requiring multiple separate cells.
2Device complexity
If multiple electrode catalysts are tested sequentially in a single cell, then device complexity is reduced, but productivity decreases due to time-consuming tests
Solution Approach 1:
The chamber is segmented into multiple independent regions that can operate simultaneously. This allows parallel testing of different electrode catalysts in different regions, dramatically increasing productivity while maintaining a single cell structure.
Solution Approach 2:
The patent enables continuous parallel operation of multiple electrochemical reactions in different chamber regions simultaneously. This continuous parallel action eliminates the need for sequential testing, thereby increasing productivity without requiring multiple separate cells.
3Manufacturing precision
If the search range for electrode catalysts and reaction conditions is expanded, then optimization quality improves, but the time required for testing increases
Solution Approach 1:
By dividing the chamber into multiple independent regions, the patent enables simultaneous testing of multiple electrode catalysts and reaction conditions. This parallel segmentation allows comprehensive optimization across a wide search range without proportionally increasing total testing time.
Solution Approach 2:
The patent implements periodic parallel testing cycles where multiple electrode catalysts are evaluated simultaneously in different chamber regions. This periodic parallel action accelerates the optimization process while maintaining comprehensive search coverage.
