Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a small amount of fuel is filled in the fuel supply box, then the fuel supply becomes unstable, but adding more fuel may cause excessive fuel supply and large flame generation
Solution Approach 1:
The patent applies parameter changes by introducing a fuel supply control valve that dynamically adjusts the fuel supply rate based on the actual fuel level in the fuel supply box. The control system monitors fuel quantity and modifies the supply parameters to maintain stable combustion, preventing both red flame (incomplete combustion) and excessive flame generation.
Solution Approach 2:
The patent implements feedback control through a control unit that continuously monitors the fuel supply state and adjusts the fuel supply control valve accordingly. When fuel level is low, the system reduces supply to prevent instability; when fuel level is adequate, it maintains optimal supply rate, creating a closed-loop control system that prevents harmful flame conditions.
2Reliability
If fuel is supplied without precise control, then the burner structure remains simple, but flame combustion becomes unstable and unsafe
Solution Approach 1:
The patent segments the fuel supply control into distinct functional components: a fuel supply control valve for flow regulation, a control unit for decision-making, and sensors for monitoring. This segmentation allows each component to perform its specific function efficiently, achieving stable combustion control while keeping the overall system design modular and manageable.
Solution Approach 2:
The patent introduces a fuel supply control valve as an intermediary device between the fuel source and the combustion chamber. This mediator component precisely regulates fuel flow based on control signals, enabling stable combustion without requiring complex direct control mechanisms, thus balancing reliability with acceptable system complexity.
