Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If complex regeneration methods and large-scale reaction vessels are used, then continuous hydrogen production is achieved, but device complexity and size increase making them unsuitable for vehicle applications
Solution Approach 1:
The patent changes the chemical parameters of the hydrogen generating material by using a two-dimensional hydrogen boride sheet with negatively charged boron atoms. This material parameter change enables the system to achieve continuous hydrogen production through simple temperature cycling and water supply, eliminating the need for complex regeneration systems while maintaining high productivity
Solution Approach 2:
The patent implements periodic action by alternating between hydrogen generating mode (heating at first predetermined temperature) and regenerating mode (cooling to second predetermined temperature and supplying water). This periodic cycling of temperature and water supply enables continuous hydrogen production without requiring complex continuous regeneration equipment, thus resolving the contradiction between productivity and device complexity
2Reliability
If complex regeneration methods are used, then hydrogen generating ability is restored, but the system requires large-scale reaction vessels and external supplementation
Solution Approach 1:
The patent enables self-service by allowing the hydrogen generating material to automatically regenerate through simple water supply during cooling. The two-dimensional hydrogen boride sheet inherently recovers its hydrogen generating ability when cooled and exposed to water, eliminating the need for external supplementation or complex regeneration operations, thus improving ease of operation for frequent refueling while maintaining reliability
Solution Approach 2:
The patent applies preliminary action by pre-cooling the hydrogen generating material to a second predetermined temperature before water supply in the regenerating mode. This preliminary temperature reduction prepares the material to efficiently absorb water and regenerate hydrogen generating ability, ensuring reliable recovery without complex operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The hydrogen generator effectively recovers the hydrogen generating ability of the two-dimensional hydrogen boride sheet through alternating temperature control and water supply, enabling continuous hydrogen production without the need for external supplementation.
Implementation Method 1
the controller controls the temperature adjustor to heat the hydrogen generating material at a first predetermined temperature so as to generate hydrogen from the hydrogen generating material
Implementation Method 2
the controller controls the temperature adjustor to adjust the temperature of the hydrogen generating material to a second predetermined temperature, which is lower than the first predetermined temperature
Implementation Method 3
the controller controls the water supply to supply water to the hydrogen generating material
