Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional structure with individual end plates and cell stacks is used, then each cell stack can be independently assembled, but the overall device complexity and number of components increases
Solution Approach 1:
The patent combines multiple end plates and attachment zones into a single integrated attachment device that can simultaneously support multiple cell stacks. This merging reduces the total number of separate components while maintaining the ability to independently assemble and disassemble cell stacks, thereby resolving the contradiction between ease of manufacture and device complexity.
Solution Approach 2:
The attachment device is designed with multiple attachment zones that can accommodate different cell stack configurations. This universal design allows the same attachment device to support various numbers and types of cell stacks, providing multi-functionality that reduces component variety while maintaining assembly flexibility.
2Stability of the object's composition
If multiple separate attachment devices are used for each cell stack, then each stack can be independently supported, but the overall device weight and component quantity increases
Solution Approach 1:
The patent merges multiple separate attachment devices into a single integrated attachment device with multiple attachment zones. This combined structure provides independent support for multiple cell stacks simultaneously, reducing the total weight and component quantity while maintaining the stability and independent configurability of each cell stack.
3Productivity
If conventional electrolysis systems are used, then hydrogen can be generated, but operational safety and economic production are compromised
Solution Approach 1:
The patent segments the electrolysis system into modular cell stacks that can be independently assembled, operated, and maintained. This segmentation allows for better control of individual cells, improving operational safety by isolating potential failure points while maintaining overall productivity through scalable configuration of multiple stacks.
