Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional gas burners use multiple gas valves and complex gas supply lines to enable different power levels, then operational versatility is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple gas valve functions into a single automatic gas valve that can control gas flow to multiple burners simultaneously. The single valve replaces what would traditionally require multiple individual valves, simplifying the gas supply system while maintaining the ability to independently control each burner's power level through electronic actuation.
Solution Approach 2:
The single automatic gas valve is designed with multi-functionality to serve multiple burners. It can selectively supply gas to different burners and regulate flow rates independently for each burner, making one component perform the work of multiple specialized components, thereby reducing overall system complexity.
2Productivity
If gas burners operate at maximum power levels continuously, then cooking speed is improved, but thermal overload and safety risks increase
Solution Approach 1:
The control unit continuously monitors the operational state of the gas burner and automatically adjusts the gas valve opening status to prevent thermal overload. When the burner reaches maximum power or shows signs of overheating, the system provides feedback to the control unit, which then reduces gas flow accordingly, creating a closed-loop safety mechanism.
Solution Approach 2:
The gas valve operates dynamically by adjusting its opening status based on real-time cooking conditions. Rather than maintaining a fixed maximum opening, the valve can modulate between partially opened and fully opened states, allowing the system to optimize cooking speed while preventing thermal overload through continuous adaptation to changing conditions.
3Device complexity
If a single automatic gas valve is used to control gas supply to the gas injector, then device complexity is reduced, but control precision for multiple power levels may be compromised
Solution Approach 1:
The patent replaces traditional mechanical multi-valve control systems with an electronically actuated single valve controlled by a microprocessor-based control unit. The electronic control system can precisely modulate the valve opening status to any position between fully closed and fully opened, providing fine-grained control over gas flow rates to achieve multiple power levels with high precision.
Solution Approach 2:
The single gas valve is capable of varying its opening status across a continuous range of parameters from 0% (fully closed) to 100% (fully opened). This continuous parameter adjustment allows precise control of gas flow rates, enabling the system to achieve multiple discrete power levels with accurate flow modulation rather than relying on fixed mechanical valve positions.
