Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate air supply apparatus and water vapor supply apparatus are used, then each component can be optimized independently, but the assembly complexity and installation space increase
Solution Approach 1:
The patent combines the air supply apparatus and water vapor supply apparatus into a single integrated air distribution plate. The plate contains both air supply holes and water vapor supply holes, allowing both functions to be performed by one component rather than requiring separate apparatus, thereby reducing assembly complexity while maintaining functional optimization
Solution Approach 2:
The air distribution plate serves multiple functions simultaneously: it distributes air to the air electrode, distributes water vapor to the storage electrode, and provides structural support. This multi-functionality eliminates the need for separate dedicated components for each function, simplifying the overall device structure
2Adaptability or versatility
If separate air supply apparatus and water vapor supply apparatus are used, then each system can be independently designed, but the installation space required increases
Solution Approach 1:
By merging the air supply and water vapor supply functions into a single air distribution plate with integrated hole patterns, the patent significantly reduces the space required for these supply systems compared to having separate apparatus, while still allowing independent design of the hole configurations for each function
Solution Approach 2:
The water vapor supply holes and air supply holes are nested within the same air distribution plate structure, with both types of holes arranged in specific patterns on the plate surface. This nesting approach allows both supply systems to occupy the same spatial envelope without interfering with each other
3Temperature
If complex material selection is made for high temperature operation, then temperature resistance is improved, but manufacturing cost and assembly complexity increase
Solution Approach 1:
The air distribution plate is made from a single homogeneous material that is resistant to the high operating temperatures of the rechargeable oxide battery. This uniform material selection simplifies manufacturing compared to using composite structures or multiple different materials, while still providing the necessary temperature resistance
Solution Approach 2:
The patent selects materials and designs the air distribution plate with parameters optimized for high-temperature operation, such as appropriate hole sizes, wall thicknesses, and material thermal properties, allowing the component to withstand operating temperatures of 600-800°C while maintaining manufacturing feasibility
