Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hydrogen cooking system uses a fixed fuel supply system, then fuel supply reliability is improved, but portability deteriorates
Solution Approach 1:
The fuel supply system is divided into separate modular components: a hydrogen storage tank module, a fuel cell module, and a cooking device module. Each module can be independently handled, connected, or disconnected, enabling the system to be transported in parts and assembled at the destination while maintaining reliable fuel supply through standardized connection interfaces.
Solution Approach 2:
The system transitions from a fixed, static fuel supply configuration to a dynamic, movable modular architecture. The modules are designed to be easily connected and disconnected, allowing the system to adapt between portable transport state and stable operation state, thus resolving the contradiction between portability and reliability.
2Ease of operation
If the hydrogen cooking system is made portable, then ease of operation is improved, but system complexity increases
Solution Approach 1:
The modular modules are designed with universal connection interfaces that can be repeatedly connected and disconnected without special tools or procedures. The standardized mechanical and electrical connections allow the same module design to serve multiple functions (storage, power generation, cooking) while simplifying the overall system assembly and reducing operational complexity despite portability requirements.
3Ease of operation
If modular modules are easily connected and disconnected, then portability is improved, but connection reliability may deteriorate
Solution Approach 1:
The mechanical connection structure and electrical connection structure are merged into an integrated connector assembly. When the mechanical interfaces are engaged, the electrical contacts are simultaneously connected, ensuring that both mechanical stability and electrical reliability are achieved in a single connection action. This combined design prevents partial connections and ensures reliable operation while maintaining ease of connection.
