Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If combustible ice is decomposed to generate high-pressure gas for electricity generation, then electricity can be produced, but great energy consumption occurs during the decomposition process
Solution Approach 1:
The patent changes the pressure parameter of the high-pressure gas from combustible ice decomposition. By utilizing the gas at different pressure levels (high-pressure portion and low-pressure portion), the system optimizes energy utilization and reduces waste, thereby addressing the high energy consumption issue during decomposition
Solution Approach 2:
The patent recovers and utilizes the low-pressure gas portion that would otherwise be discarded. The low-pressure gas is directed to a combustion device to generate heat, which is then used to preheat combustion air and support further combustion. This recovery process reduces the overall energy consumption of the decomposition process
2Power
If high-pressure gas from combustible ice decomposition is used for electricity generation, then electricity is produced, but heat energy generated by combustion is not fully used, resulting in energy waste
Solution Approach 1:
The patent implements a multi-functional system where the high-pressure gas serves dual purposes: (1) driving the gas turbine for electricity generation, and (2) providing fuel for combustion to generate heat. The heat generated is then utilized to preheat combustion air and support continuous combustion, creating a multi-functional energy utilization system that minimizes energy loss
Solution Approach 2:
The patent establishes a continuous energy utilization cycle where combustion heat preheats air that feeds into the combustion device, which in turn processes more gas. This continuous cycle ensures that heat energy is fully utilized rather than being wasted, maintaining continuous useful action throughout the system
