Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a surfactant is used to promote mixing of main fuel and combustion improver, then macroscopic mixing is improved, but molecular-level mixing is not achieved and combustion stability deteriorates
Solution Approach 1:
The patent introduces a compatibilizer as an intermediary substance between the main fuel (ammonia) and combustion improver (hydrocarbon-based liquid fuel). The compatibilizer has molecular structure characteristics that enable it to interact with both components, facilitating molecular-level mixing. This mediator approach resolves the contradiction by achieving both good macroscopic mixing and molecular-level compatibility, thereby improving combustion stability without relying solely on surfactants.
Solution Approach 2:
The patent creates a composite fuel system consisting of three components: main fuel, combustion improver, and compatibilizer. This composite approach combines substances with complementary properties where the compatibilizer's molecular structure bridges the gap between the polar main fuel and non-polar combustion improver, achieving molecular-level mixing that enhances combustion stability beyond what surfactants alone can provide.
2Stability of the object's composition
If temperature adjustment mechanism is used to maintain fuel properties, then fuel stability is maintained, but device complexity and cost increase
Solution Approach 1:
The patent employs a self-service approach where the compatibilizer inherently maintains fuel stability through its molecular compatibility with both main fuel and combustion improver. The compatibilizer prevents phase separation and maintains mixing stability without requiring external temperature adjustment mechanisms. This eliminates the need for complex heating or cooling systems while maintaining fuel stability throughout storage and supply.
Solution Approach 2:
The patent changes the chemical composition parameter by introducing the compatibilizer with specific molecular structure characteristics. This compositional change fundamentally alters the mixing behavior and stability characteristics of the fuel system, replacing the need for temperature control with inherent chemical stability. The compatibilizer's molecular properties enable stable mixing across a range of temperatures without requiring active temperature management.

AI summary
A fuel supply device, which is applied to an engine system including an engine that operates with a mixed fuel composed of a main fuel such as ammonia or an alcohol and a combustion improver made from a hydrocarbon-based liquid fuel such as light oil, kerosene, or heavy oil and supplies the mixed fuel to the engine, mixes a compatibilizer, the main fuel, and the combustion improver to produce the mixed fuel.
