Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If cells are arranged in a compact configuration to reduce module volume, then space efficiency is improved, but gas circulation to gas electrodes deteriorates
Solution Approach 1:
The module is divided into multiple cell assemblies, each with dedicated gas distribution channels. The gas distribution plate is segmented to provide individual flow paths to each cell's gas electrodes, ensuring adequate gas supply even in compact configurations.
Solution Approach 2:
Gas distribution is achieved by transitioning from a planar arrangement to a three-dimensional structure with vertical gas channels and horizontal distribution paths. This multi-dimensional approach allows efficient gas circulation within a compact volume by utilizing space in multiple directions.
2Reliability
If connection elements are made robust to resist vibrations, then connection reliability is improved, but module mass increases
Solution Approach 1:
The connection elements incorporate elastic or flexible components that can dynamically adapt to vibration forces. This dynamic design allows the connections to maintain reliability under vibrational stress without requiring excessive mass, as the elements can flex and return to their original position.
Solution Approach 2:
Connection elements are constructed using composite materials that provide high strength-to-weight ratio. These composite structures deliver the necessary mechanical strength and vibration resistance while minimizing the added mass compared to traditional solid metal connections.
3Volume of moving object
If cell terminals are closely spaced to reduce module size, then space efficiency is improved, but electrical connection reliability deteriorates
Solution Approach 1:
Connection plates serve as intermediary elements between closely spaced cell terminals. These plates provide a stable mounting surface and reliable electrical pathway, allowing terminals to be positioned close together while maintaining connection integrity through the mediating connection structure.
Solution Approach 2:
The connection plates perform multiple functions simultaneously: they provide electrical connection, mechanical support, and thermal management. This multi-functionality allows for compact terminal spacing while maintaining reliability, as a single element addresses multiple requirements rather than requiring separate components for each function.
