Solution Overview
Problem
Existing oil cleanup systems face challenges in high seas, where oil becomes emulsified and spreads thinly, making separation difficult, and require significant space and technological effort for height-adjustable solutions to manage changing ship drafts.
Innovation Solution
An apparatus with a particle separation space and a collection space connected by a separation mechanism, utilizing hydrodynamic separation and an adjustment mechanism to regulate water levels, minimizing water content in the collection space and optimizing particle uptake, which includes a pressure-regulating device for internal pressure control and eddy-stabilizing elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If height-adjustable embankments or ballast systems are used to compensate for changing ship draft, then the device can adapt to dynamically changing low position of the ship, but the technological effort and space requirement increase significantly
Solution Approach 1:
The device uses the natural buoyancy and floating characteristics of the carrier ship to automatically compensate for draft changes. The embankment structure is designed to self-adjust with the ship's motion, eliminating the need for active ballast systems or complex height-adjustable mechanisms. The system serves itself by utilizing the physical properties of floating bodies rather than requiring additional technological interventions.
Solution Approach 2:
The invention extracts and eliminates the complex ballast systems and height-adjustable mechanisms from the design. By removing these unnecessary components, the solution achieves draft compensation through the inherent floating behavior of the ship, significantly reducing technological effort and space requirements while maintaining adaptability.
2Adaptability or versatility
If height-adjustable embankments or ballast systems are used to compensate for changing ship draft, then the device can adapt to dynamically changing low position of the ship, but the storage volume for particles is reduced
Solution Approach 1:
The invention removes the space-consuming ballast tanks and height-adjustable mechanism components that would otherwise occupy valuable storage volume. By using the ship's natural floating characteristics, the design maximizes the available space for particle storage while maintaining the ability to adapt to draft changes.
Solution Approach 2:
The embankment structure is designed to self-adjust with ship motion without requiring additional space for active adjustment mechanisms. This passive adaptation approach preserves maximum storage volume for particles while still compensating for changing ship draft conditions.
3Productivity
If the carrier ship continuously takes up oil, then the ship position changes dynamically, but this requires complex measures to compensate
Solution Approach 1:
The embankment structure is designed to be dynamic and flexible, accommodating the continuously changing ship position as oil is taken up. Rather than trying to maintain a fixed ship position, the system adapts to the dynamic conditions, allowing the separation blade and embankment to function effectively throughout the uptake process.
Solution Approach 2:
The system uses the natural dynamic behavior of the floating ship during oil uptake to drive the separation process. The changing ship position creates natural flow patterns that enhance oil-water separation, turning the dynamic condition into a beneficial self-regulating mechanism rather than requiring active stabilization.

Function Achieved in This Case
Enhances efficiency in particle separation and storage by optimizing water level adjustments based on sea conditions, reducing the need for extensive storage volume and technological effort, while maintaining effective particle collection.
Implementation Method 1
In skimming an oil film from a water system, it flows along the underside of the bow of the oil-collecting device up to a separation blade, which separates the oil film from the main flow and introduces it into a particle separation chamber
Implementation Method 2
An eddy is formed at a breakaway edge of the separation blade which accelerates the oil being picked up toward the free water surface in the particle separation space
Implementation Method 3
an adjustment mechanism which is configured to regulate the filling level of the water that contains particles in the particle separation space
