Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single fuel type is used in the injection system, then the system structure is simple, but the combustion efficiency is suboptimal and fuel consumption is increased
Solution Approach 1:
The patent combines multiple fuel types (liquid fuel and gaseous fuel) into a single injection system, allowing them to be co-injected together. The gaseous fuel acts as an enhancer that improves the combustion characteristics of the liquid fuel, thereby reducing fuel consumption while maintaining system integration rather than requiring completely separate systems for different fuels.
Solution Approach 2:
The invention creates a composite fuel system where gaseous fuel and liquid fuel work together in combination. The gaseous fuel serves as a combustion enhancer that complements the liquid fuel, creating a synergistic effect that improves overall combustion efficiency and reduces the amount of primary fuel needed.
2Loss of energy
If less expensive fuel sources are used, then fuel costs are reduced, but combustion efficiency deteriorates
Solution Approach 1:
The patent changes the combustion parameters by introducing gaseous fuel as an additive to liquid fuel. This parameter change (adding gaseous component) improves the combustion characteristics of less expensive fuel sources, allowing them to burn more efficiently and effectively, thereby maintaining productivity while reducing costs.
Solution Approach 2:
The gaseous fuel acts as an intermediary or enhancer that mediates between the less expensive liquid fuel and the combustion process. It improves the combustion characteristics of the liquid fuel, enabling cheaper fuel sources to achieve better combustion efficiency without requiring expensive fuel replacements.
3Loss of energy
If multiple fuel types are combined, then combustion efficiency is improved, but the device complexity increases
Solution Approach 1:
The injection system is designed with multi-functionality to handle both liquid fuel and gaseous fuel through the same injection apparatus. The system can switch between different fuel modes and combinations, making it universal rather than requiring separate dedicated systems for each fuel type, thereby managing complexity while enabling multiple fuel types.
4Temperature
If gaseous fuel is added to liquid fuel, then the thermal response is enhanced, but the system requires real-time control mechanisms
Solution Approach 1:
The system incorporates real-time control mechanisms that monitor and adjust the mixture of gaseous and liquid fuels based on engine conditions. This feedback control ensures optimal thermal response by dynamically adjusting fuel delivery, managing the complexity of handling multiple fuel types with different combustion characteristics.
