Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If LPG is used as fuel, then combustion cleanliness is improved, but energy value decreases
Solution Approach 1:
The patent changes the physical state parameter of LPG from liquid to gas phase by heating it to approximately 40-60°C, which improves vaporization and combustion efficiency, thereby maintaining the clean combustion characteristic while improving energy utilization
Solution Approach 2:
The patent performs preliminary heating of the LPG fuel in a heating circuit before it enters the engine, ensuring the fuel is in the optimal state for combustion. This preliminary action improves combustion efficiency and maintains the clean exhaust characteristic without sacrificing energy value
2Productivity
If fuel temperature is increased to improve combustion, then combustion efficiency is improved, but fuel vaporization control becomes difficult
Solution Approach 1:
The patent incorporates a temperature sensor that continuously monitors the fuel temperature and feeds this information back to the control unit. The control unit adjusts the heating power accordingly to maintain the optimal temperature range (40-60°C), ensuring both combustion efficiency and precise vaporization control
Solution Approach 2:
The patent optimizes the fuel temperature parameter to a specific range (40-60°C) rather than simply increasing it, which balances combustion efficiency with controlled vaporization. This parameter optimization allows efficient combustion while preventing excessive vaporization that would be difficult to control
3Object-generated harmful factors
If air is added to the fuel mixture to improve combustion, then exhaust pollutants are reduced, but mixture homogeneity decreases
Solution Approach 1:
The patent uses a pneumatic system where pressurized air is injected through a nozzle into the fuel tank. This pneumatic injection creates a fine aerosol of air and fuel, ensuring homogeneous mixing while allowing excess air to be vented, thus reducing pollutants without compromising mixture homogeneity
Solution Approach 2:
The patent applies air injection locally at the fuel storage point rather than uniformly throughout the entire system. The air is injected at a specific location (through the nozzle in the fuel tank) where it creates localized turbulence and mixing, improving homogeneity at the critical mixing point while allowing overall air-fuel ratio control
