Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional power-generating systems are used, then energy production is achieved, but cost and environmental harm increase
Solution Approach 1:
The patent changes the fundamental parameter of working fluid from gas to liquid, utilizing liquid expansion rather than combustion. This parameter change eliminates harmful emissions while maintaining energy production efficiency through heat-driven volumetric expansion of the liquid working fluid.
Solution Approach 2:
The patent replaces conventional mechanical combustion systems with a thermal expansion system. Instead of using combustion engines or turbines, the invention uses heat-driven liquid expansion to directly drive a piston, substituting a simpler thermal-mechanical system for complex combustion machinery.
2Object-affected harmful factors
If liquid working fluid is used, then environmental impact is reduced, but conversion of heat expansion to mechanical work becomes complex
Solution Approach 1:
The patent extracts the working fluid from the cylinder through a valve when expansion is complete, separating the power stroke from the intake and exhaust processes. This extraction mechanism simplifies the overall system by allowing the fluid to be reused in the next cycle without requiring complex multi-valve timing mechanisms.
Solution Approach 2:
The system employs periodic action through cyclic heating and cooling of the liquid working fluid. The fluid is heated to expand, then cooled to contract, creating a repeating cycle that drives the piston back and forth. This periodic thermal action converts continuous heat input into discrete mechanical work cycles.
