Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electrolyte tanks and stacks are transported and installed separately, then the transportation flexibility is improved, but the installation time and complexity increase significantly
Solution Approach 1:
The patent combines the electrolyte tanks and stacks into a single integrated module that can be transported as one unit. This merging eliminates the need for separate transportation and on-site assembly of tanks and stacks, thereby reducing installation time and complexity while maintaining transportation flexibility through modular container designs.
Solution Approach 2:
The tanks and stacks are pre-assembled and pre-connected in a factory setting before transportation. This preliminary action ensures that all connections and configurations are completed under controlled conditions, eliminating the need for complex on-site assembly and reducing installation time at the deployment location.
2Ease of manufacture
If the electrolyte tanks and stacks are transported separately, then the transportation logistics are simplified, but the pipe work and assembly complexity on site increase
Solution Approach 1:
By merging the tanks and stacks into an integrated module with pre-installed piping and connections, the patent simplifies transportation logistics while simultaneously reducing assembly complexity on-site. The integrated design ensures that all components are already configured and connected, eliminating the need for complex field assembly operations.
Solution Approach 2:
The patent segments the entire battery system into standardized modular units that can be easily handled and transported. Each module is self-contained with all necessary components integrated, allowing for simple logistics while maintaining low assembly complexity through standardized interfaces and pre-configuration.
3Adaptability or versatility
If the system is assembled on site in modules, then the installation flexibility is improved, but the testing and assembly difficulty increase
Solution Approach 1:
The patent performs preliminary assembly, testing, and validation of all module components in the factory before shipment. This ensures that each module arrives at the site as a fully tested, ready-to-operate unit, maintaining installation flexibility while eliminating the difficulty of on-site testing and assembly operations.
