Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If hydrogen is stored at high pressures near 700 bar, then adequate quantities of hydrogen can be stored for extended energy consumption, but more robust components are required which increases system weight and complexity
Solution Approach 1:
The patent changes the pressure parameter from high pressure (700 bar) to low pressure storage, and changes the hydrogen state from gaseous to solid form through chemical reactions. This allows adequate hydrogen storage quantity without requiring robust high-pressure components, thereby reducing system weight
Solution Approach 2:
The patent utilizes phase transitions by converting gaseous hydrogen to solid form through chemical reactions with metals or metal hydrides. The solid hydrogen storage material can be controllably converted back to gaseous hydrogen when needed, enabling adequate storage quantity at low pressures without heavy containment systems
2Quantity of substance
If hydrogen is stored at high pressures near 700 bar, then adequate quantities of hydrogen can be stored for extended energy consumption, but the system requires more robust components designed to handle high pressures
Solution Approach 1:
The patent changes the pressure parameter from high pressure (700 bar) to low pressure storage, and changes the hydrogen state from gaseous to solid form. This simplifies the system by eliminating the need for robust high-pressure components, valves, and safety systems, thereby reducing device complexity
Solution Approach 2:
The patent utilizes phase transitions to store hydrogen in solid form at low pressures and convert it to gaseous form on demand. This approach eliminates the need for complex high-pressure containment and delivery systems, significantly reducing overall system complexity
3Productivity
If gaseous hydrogen is stored and delivered, then immediate energy consumption is possible, but safety risks increase due to potential leaks and handling requirements
Solution Approach 1:
The patent stores hydrogen in solid form and uses controlled phase transitions to gaseous form only when energy is needed. The solid hydrogen storage material can be controllably converted to gaseous hydrogen through chemical reactions, providing immediate energy delivery while minimizing safety risks during storage and transport
Solution Approach 2:
The patent introduces metal or metal hydride as an intermediary substance that chemically binds with hydrogen to form solid hydrogen storage material. This intermediary enables safe storage and controlled release of hydrogen, reducing safety risks while maintaining the ability to deliver hydrogen gas rapidly when needed
