Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If methanol and gasoline are mixed in a fuel tank, then fuel storage is simplified, but uniform mixing is difficult to maintain due to physical and chemical property differences
Solution Approach 1:
The patent applies preliminary action by pre-mixing methanol and gasoline in a mixing chamber before the fuel enters the fuel injection system. This pre-mixing ensures uniform composition is achieved before combustion, preventing stratification issues that would occur if mixing relied solely on tank conditions.
Solution Approach 2:
The patent replaces traditional mechanical mixing methods with microwave heating. The microwave heating device uses electromagnetic radiation to heat the fuel mixture, which promotes uniform mixing and prevents stratification without requiring complex mechanical stirrers or pumps.
2Productivity
If ECU adjusts fuel injection volume to achieve full combustion, then fuel combustion efficiency improves, but information feedback lag occurs resulting in insufficient cylinder combustion
Solution Approach 1:
The patent applies preliminary action by pre-mixing the fuel in the mixing chamber before injection. This ensures that the fuel mixture is already uniform and optimized for combustion when it enters the cylinder, eliminating the need for ECU adjustments that suffer from feedback lag.
Solution Approach 2:
The patent incorporates a feedback mechanism where the control unit monitors the working state of the microwave heating device and adjusts its operation accordingly. This feedback ensures optimal heating and mixing conditions are maintained throughout the fuel delivery process.
3Temperature
If traditional heating methods are used to warm fuel, then fuel temperature increases, but heat is wasted and heating is uneven
Solution Approach 1:
The patent replaces traditional conductive or convective heating methods with microwave heating. The microwave heating device uses electromagnetic radiation to directly heat the fuel molecules, achieving uniform and efficient heating without heat loss to surrounding components.
Solution Approach 2:
The patent changes the heating parameter from thermal conduction/ convection to electromagnetic radiation. This parameter change enables direct molecular excitation and heating, resulting in uniform temperature distribution and high heating efficiency across the fuel mixture.
