Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a smaller liquid intake hole is used to prevent oil leakage when liquid level pressure is high, then oil leakage is prevented, but insufficient oil supply occurs when liquid level and pressure drop
Solution Approach 1:
The patent introduces a movable piston that can shift position within the liquid intake channel based on liquid level pressure. When liquid level pressure is high, the piston moves to block the liquid intake hole to prevent leakage. When liquid level and pressure drop, the piston moves back to allow sufficient oil supply. This dynamic adjustment mechanism resolves the contradiction between preventing leakage and ensuring adequate supply.
Solution Approach 2:
The patent changes the effective opening size of the liquid intake hole dynamically through the piston movement. The opening parameter is adjusted based on liquid level pressure conditions, transitioning from a blocked state (preventing leakage) to an open state (ensuring supply). This parameter change approach allows the system to adapt to varying pressure conditions.
2Quantity of substance
If a larger liquid intake hole is used to ensure sufficient oil supply when liquid level and pressure drop, then oil supply is sufficient, but oil leakage occurs when liquid level pressure is high
Solution Approach 1:
The movable piston provides dynamic control over the liquid intake hole opening. When liquid level and pressure are low, the piston retracts to maximize the opening for sufficient supply. When liquid level pressure rises, the piston advances to reduce or block the opening to prevent leakage. This dynamic mechanism allows the system to achieve both sufficient supply and leakage prevention under different operating conditions.
Solution Approach 2:
The piston is designed to move automatically in response to liquid level pressure changes without external control. The pressure differential itself drives the piston movement, creating a self-regulating system that adjusts the opening size according to the current liquid level conditions, thereby preventing leakage while ensuring supply.
3Ease of manufacture
If the size of the liquid intake hole is kept constant, then manufacturing is simple, but liquid pressure changes cause atomization problems and core burning
Solution Approach 1:
While maintaining a constant physical hole size for manufacturing simplicity, the patent introduces a movable piston that dynamically adjusts the effective opening. This allows the system to maintain manufacturing simplicity while achieving variable flow characteristics to ensure reliable atomization under different liquid pressure conditions, preventing core burning.
Solution Approach 2:
The piston acts as an intermediary element between the constant-size liquid intake hole and the variable liquid pressure conditions. It mediates the flow through the hole by adjusting its position, thereby maintaining manufacturing simplicity while ensuring atomization stability across different operating conditions.

Implementation Method 2
the capillary force generated by the gap between the pressure stabilizing tube and the support prevents the atomizable liquid from leaking through the air vent hole
