Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a media module is applied to connect several fuel cell stacks, then the connection and assembly are achieved, but the cycle time and production costs increase
Solution Approach 1:
The patent removes the separate media module component from the assembly and integrates its functions directly into the housing structure. The housing now incorporates the media seal and connection features, eliminating the need for a distinct media module that would increase assembly complexity and cycle time.
Solution Approach 2:
The patent combines multiple functions into the housing structure: the housing serves as both the structural enclosure and the media separation component. By integrating the media seal and stack connection features directly into the housing, the design eliminates separate components and simplifies the assembly process.
2Ease of manufacture
If a media module is applied to connect several fuel cell stacks, then the connection and assembly are achieved, but the material costs and production costs increase
Solution Approach 1:
The patent eliminates the separate media module component, thereby removing the associated material costs. The housing structure assumes the media separation function, reducing the total quantity of materials required for assembly.
Solution Approach 2:
The housing is designed to perform multiple functions: structural enclosure, media separation, and stack connection. This multi-functionality eliminates the need for separate dedicated components, reducing material quantity and production costs.
3Strength
If the plastic base uses glass fiber reinforcement for structural strength, then the mechanical strength is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent employs glass fiber-reinforced plastic for the base structure, combining the strength benefits of glass fiber with the formability and corrosion resistance of plastic. This composite material approach achieves high structural strength while maintaining manufacturing feasibility through established composite molding techniques.
