Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If energy resources are procured from resource-rich locations, then energy supply is ensured, but transportation costs increase and energy loss occurs
Solution Approach 1:
The system divides the energy production function into multiple distributed generation units (wind turbines, tidal generators, solar panels) located at different positions around the offshore platform, enabling local energy production close to consumption points and reducing transportation needs
Solution Approach 2:
The offshore platform becomes self-sufficient by producing its own energy through multiple natural energy sources, generating hydrogen through electrolysis for fuel, and producing oxygen for various processes, thereby eliminating dependence on external energy imports and reducing transportation-related energy losses
2Object-affected harmful factors
If natural energy power generation is used, then environmental friendliness is improved, but output is limited by meteorological conditions and location
Solution Approach 1:
The system combines multiple complementary natural energy sources (wind power, tidal power, solar power, wave power, temperature difference power) into a single integrated energy generation system, where each source compensates for the limitations of others, ensuring stable energy output regardless of meteorological conditions or location
Solution Approach 2:
The offshore platform serves multiple functions simultaneously: energy generation, hydrogen production, oxygen production, desalination, and agricultural cultivation, making the system adaptable to various environmental conditions and locations while maintaining high productivity through diversified operations
3Adaptability or versatility
If ocean resources are utilized for energy production, then energy self-sufficiency is improved, but ocean oxygen deficiency causes red tides
Solution Approach 1:
The system converts the harmful effect of ocean oxygen deficiency into a beneficial outcome by using electrolysis to generate oxygen from seawater, which is then released back into the ocean environment, transforming the original problem into an environmental solution that prevents red tides while maintaining energy self-sufficiency
Solution Approach 2:
The system recovers oxygen from the electrolysis process of seawater decomposition, capturing and releasing it into the ocean to replenish oxygen levels, thereby converting a waste product of energy generation into a beneficial substance that prevents environmental harm

AI summary
Using electric power obtained by marine wind force and a tide, sea water is electrolyzed to produce fresh water, sodium, magnesium, calcium, potassium, caustic soda, chlorine, hydrochloric acid, sulfuric acid, hydrogen, oxygen or the like, at the same time, unloaded malts, saw dust and the like are fermented to brew ethanol, carbon dioxide generated here is used for photosynthesis to culture vegetables and oxygen generated here is supplied to a fish preserve and an under reef where fish live to culture fishes and also returned to sea water dropped in the concentration of oxygen to suppress the generation of a red tide.
