Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional transmission towers and lines are used for power supply, then power can be transmitted over long distances, but environmental impact increases and vulnerability to natural disasters occurs
Solution Approach 1:
The patent extracts and eliminates transmission towers and overhead lines from the power supply system, replacing them with underground cables. This removes the harmful visual and environmental impact of towers while also eliminating their vulnerability to natural disasters like typhoons and earthquakes.
Solution Approach 2:
The patent introduces hydrogen as an intermediary energy carrier. Instead of directly transmitting electricity over long distances through vulnerable infrastructure, electricity is converted to hydrogen for storage and transport, then converted back to electricity locally. This intermediary approach enables resilient local power generation without requiring vulnerable transmission infrastructure.
2Ease of manufacture
If hydrogen is produced and transported centrally, then power supply can be established, but production and transportation costs increase
Solution Approach 1:
The patent segments the centralized hydrogen production and transport system into distributed local production units. Each region produces its own hydrogen locally using water electrolysis powered by renewable energy, eliminating the need for expensive long-distance hydrogen transportation infrastructure.
Solution Approach 2:
Each region becomes self-sufficient by producing its own hydrogen and electricity locally. The system uses local renewable energy resources (sun, wind, water) to generate electricity for water electrolysis, creating a self-service model that eliminates dependence on external hydrogen supply chains and reduces transportation costs.
3Object-generated harmful factors
If hydrogen energy system is implemented, then clean energy supply is achieved, but conversion inefficiencies occur
Solution Approach 1:
The patent implements continuous operation of water electrolysis plants and hydrogen-powered generators. By keeping the hydrogen production and conversion systems running continuously rather than intermittently, the system maintains optimal conversion efficiency and minimizes energy losses associated with repeated startup and shutdown cycles.
