Solution Overview

Problem

Existing systems for applying fluids to anchor chains and cables in marine environments fail to effectively prevent corrosion, leading to rust and potential breaking, creating hazardous conditions.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple washing system is used for the anchor chain, then the device complexity is reduced, but the corrosion protection effectiveness deteriorates

Engineering Contradiction:
Improvedevice complexityVSAvoidcorrosion protection effectiveness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The conduit is divided into multiple sections with nozzles positioned at different locations along its length. Each nozzle applies fluid to a specific segment of the chain, ensuring complete coverage without requiring a complex multi-component system. The segmentation of the fluid application process into multiple localized points achieves effective corrosion protection while maintaining relatively simple device structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces flaps as a third dimensional element that actively engages with the chain surface. These flaps extend from the conduit walls and create a three-dimensional fluid distribution pattern, allowing the fluid to be applied not just from the center but also from multiple angular directions. This dimensional approach ensures comprehensive coverage and effective corrosion protection without significantly increasing device complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Manufacturing precision

If multiple nozzles are added to the conduit, then the fluid distribution uniformity is improved, but the device complexity increases

Engineering Contradiction:
Improvefluid distribution uniformityVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The conduit serves multiple functions simultaneously: it acts as the fluid delivery channel, provides structural support, and houses the nozzle system. The flaps also perform dual functions by directing fluid flow and maintaining chain alignment. This multi-functionality allows multiple nozzles to be integrated into a single unified structure, achieving uniform fluid distribution without proportionally increasing device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The flaps are designed to be movable rather than fixed, allowing them to dynamically adjust to the chain's position and movement. This dynamic element compensates for variations in chain tension and position, ensuring that the fluid from multiple nozzles is distributed uniformly across the chain surface regardless of operational conditions, while the flexible nature of the flaps simplifies the overall structure compared to rigid multi-component systems.

Inventive Principle:
Principle #15Dynamics

3Reliability

If flaps are added to aid in fluid catchment and smearing, then the corrosion protection effectiveness is improved, but the device complexity increases

Engineering Contradiction:
Improvecorrosion protection effectivenessVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The flaps are integrated directly into the conduit structure rather than being separate components. They are formed as extensions or attachments to the conduit walls, merging the fluid distribution function with the existing structural element. This integration achieves effective fluid catchment and smearing for superior corrosion protection while minimizing the increase in device complexity by combining functions into a unified structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The flaps utilize the kinetic energy of the flowing chain and the pumped fluid to perform their function automatically. As the chain moves through the conduit, the flaps naturally position themselves to catch and direct the fluid onto the chain surface without requiring additional actuators or control mechanisms. This self-service approach achieves effective corrosion protection while maintaining simple device structure.

Inventive Principle:
Principle #25Self-service
