Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If renewable energy sources (wind, tide, sunlight) are used to generate electrical energy, then environmental pollution is eliminated, but the electrical energy stream becomes variable and cannot maintain constant output
Solution Approach 1:
The system performs preliminary action by storing excess renewable energy in the temperature-pressure tank when energy is abundant, preparing it for later use when energy demand exceeds supply. This advance storage of thermal energy in the tank enables the system to maintain constant electrical output despite the variable nature of renewable sources.
Solution Approach 2:
The system utilizes parameter changes by converting electrical energy to thermal energy (changing energy form and temperature parameter) for storage in the tank. The stored thermal energy is then converted back to electrical energy through the turbine system, effectively changing parameters to resolve the contradiction between variable input and constant output requirements.
2Stability of the object's composition
If fossil fuels or biomass are burned to produce constant electrical energy stream, then stable power output is achieved, but exhaust gases and dusts are produced causing environmental devastation
Solution Approach 1:
The system replaces the chemical combustion process (mechanical-chemical system) with a thermal storage and conversion system. Instead of burning fossil fuels to generate heat and drive turbines continuously, the system uses electrical heating elements to heat a transmission agent in the tank, storing thermal energy without combustion, thus eliminating exhaust gases and dusts while maintaining constant power output.
3Use of energy by moving object
If thermal energy is transmitted through solid heat storage medium, then energy can be stored, but significant energy losses occur
Solution Approach 1:
The system applies pneumatic and hydraulic principles by using a fluid transmission agent (gas or liquid) instead of solid heat storage medium. The transmission agent circulates through the system, absorbing heat from heating elements and delivering it to the turbine. This fluid-based approach reduces thermal resistance and improves heat transfer efficiency, minimizing energy losses compared to solid medium storage.
Solution Approach 2:
The transmission agent acts as an intermediary between the heating elements and the turbine. This mediator substance efficiently transfers thermal energy through circulation, reducing direct thermal losses and improving overall energy transmission efficiency compared to conducting heat through solid media.

AI summary
The subject of the invention is a method and system for renewable energy store in temperature-pressure tank of energy and conversion to electrical energy. It makes possible conversion of variable stream of renewable energy, especially of wind, tide and the sun, to constant stream of electrical energy. Considerable part of renewable energy stream is accumulated in substance in artificial or natural tank (6). The heat collected in tank (6) is transferred to transmission agent, which as the gas with pressure drives turbine (11) and electrical generator (12). Renewable energy stream sensor (15) gives the information about actual renewable energy stream power to control system (3). Proper steering of: converter (4) /or mirror and heater in the sun energy system version/ and control modules (8, 10, 14, 13), additionally using of energy accumulated in rotating mass of turbine rotor (1) /in wind and tides energy system version/ gives possibility of receiving constant stream of electrical energy. While renewable energy stream is present, it is possible the simultaneous work of generator (2) with converter (4) /or mirror and heater in the sun energy system version/ and generator (12) what gives even two times bigger output power of the system. If conversion of voltage produced by converter (4) and/or generator (12) to voltage of electrical grid is needed transformer (16) can be used. Moreover transformer (16) power is lower than power of generator (2) /or mirror and heater in the sun energy system version/. It is worth of mentioning that in heat exchanger (14) additional stream of heat is received, which can be used for other purposes.
