Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single electrode is used for both ignition and flame ionization, then cost is reduced, but measurement precision deteriorates
Solution Approach 1:
The system employs periodic action by alternating the single electrode between ignition mode and flame ionization measurement mode. During ignition phases, the electrode generates sparks to ignite the gas/air mixture. During measurement phases, the electrode functions as a flame ionization sensor. This time-division multiplexing allows one electrode to perform both functions sequentially, resolving the contradiction between cost reduction and measurement precision.
Solution Approach 2:
The system implements dynamics by making the electrode's function changeable over time. The control device dynamically switches the electrode between two operational states: ignition state (generating high-voltage sparks) and measurement state (detecting flame ionization signals). This dynamic functionality allows a single electrode to replace what would traditionally require two separate electrodes, reducing cost while maintaining measurement capability.
2Device complexity
If a single electrode is used for both ignition and flame ionization, then device complexity is reduced, but reliability deteriorates
Solution Approach 1:
The control device uses periodic action to alternately switch the single electrode between ignition function and flame ionization measurement function. During ignition phases, the electrode operates as an igniter; during measurement phases, it operates as a sensor. This temporal separation ensures that the electrode's dual role does not compromise reliability, as each function is performed during its designated time window with appropriate control signals.
Solution Approach 2:
The control device acts as an intermediary that manages the single electrode's dual functionality. It receives signals from the electrode, determines whether the electrode should function as an igniter or a sensor based on operational phase, and processes the appropriate signals accordingly. This intermediary control mechanism ensures reliable operation despite the electrode's multifunctional role.
