Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multiple electrode pairs are arranged in series inside the case, then the ionic wind can be generated and emitted as a jet stream, but the electric field is reversed in between the electrode pairs which disturbs the acceleration of ions
Solution Approach 1:
The device segments the ionic wind generation process into two distinct functional zones: a corona discharge generation zone (first discharge electrode and reference electrode) and an acceleration zone (second discharge electrode and control electrode). This segmentation allows independent optimization of ion generation and ion acceleration, resolving the contradiction by separating the functions that were previously coupled in a single electrode pair arrangement.
Solution Approach 2:
The control electrode acts as an intermediary element between the reference electrode and the second discharge electrode. It receives accelerated ions from the first discharge zone and facilitates further acceleration in the second zone, mediating the transition between different electric field configurations and enabling continuous ion acceleration without the reversal problem of traditional series arrangements.
2Speed
If the electric field is reversed between electrode pairs to maintain alternating polarity, then electrode balance is maintained, but acceleration of ions is disturbed and ionic wind acceleration is reduced
Solution Approach 1:
The invention introduces dynamic control of electric fields through separate power supply circuits for different electrode zones. The first power supply circuit generates corona discharge between the first discharge electrode and reference electrode, while the second power supply circuit creates an accelerating field between the second discharge electrode and control electrode. This dynamic, independently controllable electric field configuration allows optimization of ion acceleration while maintaining overall system reliability.
3Speed
If a single electrode pair is used, then the device structure is simple, but the ionic wind acceleration is insufficient
Solution Approach 1:
The electrode system is designed with multi-functionality where different electrode pairs serve different purposes within the same device. The first discharge electrode and reference electrode pair primarily generates corona discharge and ions, while the second discharge electrode and control electrode pair primarily accelerates the ions. This universal design allows the device to achieve both ion generation and strong acceleration functions without requiring completely separate systems.
