Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional coalescence separation devices are used, then separation function is provided, but device volume and weight are excessive for offshore applications
Solution Approach 1:
The device segments the fluid flow into multiple radial flow paths between alternating polarity plates, creating numerous small-scale separation zones within a compact structure. This segmentation allows efficient separation without requiring large device volume.
Solution Approach 2:
The invention transitions from conventional horizontal/vertical flow arrangements to a radial flow configuration between parallel plates. This dimensional change enables compact stacking of separation stages while maintaining effective separation distance, reducing overall device volume.
2Duration of action of stationary object
If conventional coalescence devices are used, then separation occurs, but maintenance frequency is high and lifespan is limited
Solution Approach 1:
The alternating polarity plates automatically reverse electric field directions in a rotating sequence, creating self-regenerating separation zones that prevent permanent contamination buildup. This self-service mechanism reduces maintenance frequency and extends device lifespan without requiring manual intervention.
Solution Approach 2:
The device dynamically changes the electric field polarity parameters through sequential activation of plates with alternating polarity. This parameter variation prevents fouling and maintains separation efficiency over extended operational periods, reducing maintenance needs.
3Volume of moving object
If compact coalescence devices are used, then device dimensions are reduced, but flow constancy and separation efficiency deteriorate
Solution Approach 1:
The sequential activation of plates with alternating polarity creates continuous separation action throughout the device volume. As fluid moves radially between plates, multiple active separation zones operate in sequence, ensuring continuous and constant separation efficiency despite compact dimensions.
Solution Approach 2:
The device employs dynamic sequential activation of electric fields between alternating polarity plates, creating moving separation zones that track with fluid flow. This dynamic operation maintains high separation efficiency in a compact configuration by continuously renewing active separation areas.
4Weight of moving object
If conventional separation systems are used, then separation function is achieved, but device weight is excessive for offshore installations
Solution Approach 1:
The invention replaces heavy mechanical coalescence mechanisms with an electric field-based separation system using alternating polarity plates. This substitution eliminates complex mechanical components, significantly reducing device weight while maintaining or improving separation performance through electrostatic forces.
