Solution Overview

Problem

Current methods for transferring goods to and from unmanned platforms, especially in adverse weather conditions, are hazardous due to reliance on manual handling via small boats, which increases risk during wave and weather-related challenges.

Innovation Solution

A transfer system utilizing a single cable winch system with a tensioning winch and transfer winch, featuring a retractable and rotatable foundation element, cable tension controller, position controller, emergency overload release, and integrated power supply, allowing for safe and efficient transfer of goods up to 500 kg between a floating ship and shore or platform.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If manual handling via small boats is used to transfer goods to unmanned platforms, then installation complexity is reduced, but safety deteriorates in adverse weather conditions

Engineering Contradiction:
Improveinstallation complexityVSAvoidsafety
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent replaces the manual mechanical handling system with an automated cable winch system. The winch system mechanically transfers goods from the ship to the platform without requiring manual handling by workers in small boats, thereby eliminating safety risks while maintaining simple installation through standardized mounting components.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If multiple cables are used in the transfer system, then reliability improves, but device complexity increases

Engineering Contradiction:
Improvesystem reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple cable functions into a single integrated cable system. The single cable performs both guiding and load-bearing functions simultaneously, eliminating the need for separate guiding cables and pulling cables. This merging reduces the number of system parts to a minimum while maintaining system reliability through proper cable routing and tensioning mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If a retractable foundation element is provided, then adaptability improves, but device complexity increases

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidfoundation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a retractable foundation element that can extend and retract to adapt to different positioning requirements. The foundation element includes a retractable beam structure that can be extended during transfer operations and retracted when not in use, providing positioning flexibility while minimizing impact on device complexity through standardized mechanical extension mechanisms.

Inventive Principle:
Principle #15Dynamics
