Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a gas combustor provides only igniting function, then the structure is simple, but the combustion assisting function is missing requiring manual fanning or blowing
Solution Approach 1:
The patent merges the igniting device and combustion assisting device into a single integrated gas combustor system. The igniting device includes a fuel gas supplying mechanism and piezoelectric ignition device, while the combustion assisting device includes a fan switch and impeller. Both devices share common components such as the main body, control part, and safety buttons, achieving functional integration without proportionally increasing complexity.
Solution Approach 2:
The gas combustor is designed to perform multiple functions: igniting combustibles through the piezoelectric ignition device and assisting combustion through the impeller-driven airflow generation. The double pipe design allows simultaneous ejection of flame and airflow, enabling the device to serve both ignition and combustion enhancement purposes in a single unit.
2Ease of operation
If separate ignition and fan switches are provided, then the operation control is improved, but the risk of simultaneous operation causing safety issues increases
Solution Approach 1:
The patent implements preliminary anti-action through the interlocking mechanism between the ignition switch and fan switch. When the ignition switch is activated, the fan switch is automatically blocked from operation, and vice versa. This preventive mechanism stops the harmful simultaneous operation before it can occur, ensuring safety while maintaining separate control options.
Solution Approach 2:
The control part acts as an intermediary mechanism between the ignition switch and fan switch. It contains the interlocking logic that mediates the interaction between the two switches, preventing simultaneous activation while allowing independent operation under appropriate conditions. The control part translates user input into safe operational sequences.
3Reliability
If safety buttons are added to prevent unintentional operation, then the operation safety is improved, but the device complexity increases
Solution Approach 1:
The safety buttons are designed to automatically engage and disengage based on the operational state of the igniting and combustion assisting devices. The system self-regulates safety protection without requiring additional complex control logic or external monitoring. The safety mechanism serves itself by responding inherently to the device state.
