Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If traditional pressurization and expansion method is used to generate high-speed gas flow, then gas flow speed can be increased, but energy consumption increases and energy source waste occurs

Engineering Contradiction:

Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The patent replaces the traditional mechanical pressurization system with a thermal energy conversion system. Instead of using mechanical compressors to pressurize gas and then expand it through nozzles, the invention uses a working medium that absorbs heat from the natural environment to directly generate high-speed gas flow through thermal-to-mechanical energy conversion, eliminating the need for mechanical pressurization equipment and reducing energy consumption

Inventive Principle:

Solution Approach 2:

The patent utilizes phase transitions of the working medium as the core mechanism for energy conversion. The working medium absorbs heat from the environment, undergoes phase change (evaporation/boiling), and converts thermal energy directly into kinetic energy of gas flow, achieving high-speed gas generation without mechanical pressurization and fossil fuel combustion

Inventive Principle:
Principle #36Phase transitions
