Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hydrogen gas is used as fuel in internal combustion engines, then emissions are reduced and efficiency is increased, but consistent fuel supply at low speeds and prevention of premature combustion at high speeds become difficult to maintain
Solution Approach 1:
The patent changes the physical state of hydrogen from compressed gas to liquid form, and controls its vaporization rate to maintain consistent fuel supply across different engine speeds. This parameter change resolves the contradiction by enabling reliable low-speed operation while preventing premature combustion at high speeds through controlled vaporization.
Solution Approach 2:
The system pre-cools hydrogen gas to liquid form and pre-regulates its storage temperature before injection. This preliminary action ensures that hydrogen is ready for immediate controlled vaporization, maintaining consistent fuel supply reliability while enabling the efficiency gains of hydrogen combustion.
2Quantity of substance
If hydrogen is stored in compressed gas form, then storage density is improved, but safety risks and premature combustion increase
Solution Approach 1:
The patent utilizes the phase transition of hydrogen from gas to liquid form for storage, achieving high storage density similar to compressed gas. However, by controlling the phase transition through regulated vaporization, it eliminates premature combustion risks while maintaining safety. The liquid hydrogen is vaporized at controlled rates matching engine demand.
Solution Approach 2:
The system introduces a vaporization chamber as an intermediary between liquid hydrogen storage and the combustion chamber. This intermediary allows controlled phase transition and regulates hydrogen delivery, preventing premature combustion while maintaining high storage density in liquid form.
3Adaptability or versatility
If electrolysis is used to generate hydrogen on-board, then fuel independence is improved, but water consumption and battery usage increase
Solution Approach 1:
The patent recovers and reuses water from the electrolysis process and combustion byproducts. The system condenses water vapor from exhaust and combustion chamber, purifies it, and feeds it back to the electrolysis cell. This recovery process minimizes water consumption while maintaining fuel independence through on-board hydrogen generation.
