Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct access to electrical power grid is required for charging road segments, then reliable power supply is achieved, but location flexibility and ease of deployment are worsened
Solution Approach 1:
The patent extracts the power generation capability from the centralized electrical grid and places it directly at the charging road segment location using standalone hydrogen fuel cells. This allows the charging infrastructure to be deployed independently of grid access, improving location flexibility while maintaining power supply reliability through on-site generation.
Solution Approach 2:
The charging road segments become self-sufficient by generating their own electricity through hydrogen fuel cells. The system produces and stores hydrogen locally, converting it to electricity when needed, thereby serving its own power needs without external grid dependency.
2Adaptability or versatility
If solar or wind power is used as alternative power sources, then grid independence is improved, but reliability and consistency of power supply are worsened due to weather dependence
Solution Approach 1:
The patent changes the operational parameters of hydrogen fuel cells to match varying electrical demands. By adjusting the hydrogen generation rate, particle size, and surface area of aluminum particles in the reaction vessel, the system can reliably meet different power requirements regardless of weather conditions, providing consistent power supply while maintaining grid independence.
Solution Approach 2:
The system dynamically adjusts hydrogen production and fuel cell operation based on real-time electrical demand. The control system modifies reaction conditions and power output to match varying loads, ensuring reliable and consistent power supply unlike static weather-dependent sources.
3Adaptability or versatility
If hydrogen fuel cell system is used for remote charging roads, then location flexibility and grid independence are improved, but system complexity and difficulty of setup are worsened
Solution Approach 1:
The patent combines hydrogen generation, storage, and fuel cell power generation into an integrated standalone system. By merging these functions and controlling key parameters like aluminum particle characteristics and reaction pressure, the system achieves deployment flexibility in remote locations while managing overall system complexity through unified design.
