Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for connecting flotation devices are unpredictable and insecure, often resulting in unintended movement or drifting due to the length of the securing line, and may not be applicable to all types of flotation devices without handholds.

Innovation Solution

A connection system comprising a clamp, a line length adjuster, and a connector that allows for adjustable line length between 1 and 7 feet, enabling secure and predictable attachment of flotation devices to vessels or other flotation devices, using components like single bolt or spring clamps, retractable pulley devices, and various materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a line is used to secure the flotation device, then the flotation device is connected to another vessel or flotation device, but the flotation device behaves in unpredictable ways and may float closer or farther than desired

Engineering Contradiction:

Improveconnection simplicityVSAvoidconnection predictability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies a retractable line mechanism that allows the line length to be dynamically adjusted between extended and retracted states. This dynamic adjustment capability enables predictable control over the flotation device's position relative to the vessel, resolving the unpredictability issue while maintaining ease of connection.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of line length from fixed to variable through the retractable mechanism. By allowing the line length parameter to be adjusted, the system achieves predictable positioning of the flotation device at desired distances, eliminating the unpredictable behavior associated with fixed-length lines.

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If a fixed-length line is used to secure the flotation device, then the connection is simple, but the flotation device cannot be positioned at a desired distance

Engineering Contradiction:

Improveconnection system simplicityVSAvoiddistance adjustment capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The retractable line mechanism provides dynamic length adjustment while maintaining a relatively simple overall system structure. The line can be extended or retracted as needed, offering adaptability for different positioning requirements without significantly increasing system complexity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The retractable line mechanism serves multiple functions: it provides secure attachment, enables distance adjustment, and accommodates various flotation device positions. This multi-functionality increases adaptability while keeping the connection system relatively simple through a single integrated mechanism.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If a line is used to connect the flotation device, then the flotation device is secured, but the line may result in tangling and unpredictable movement

Engineering Contradiction:

Improvesecuring effectivenessVSAvoidtangling and unpredictable movement

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the traditional free-moving line mechanism with a controlled retractable line system. This substitution eliminates tangling by providing structured line management through the retractable mechanism, while maintaining secure attachment effectiveness.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The retractable line mechanism provides controlled line deployment and retraction, preventing the line from becoming loose and tangled. The mechanism ensures the line remains taut and organized, eliminating unpredictable movement caused by loose lines while maintaining secure securing effectiveness.

Inventive Principle:

Principle #23Feedback

4Adaptability or versatility

If existing connection methods are used, then the flotation device can be connected, but the method is not applicable to all types of flotation devices without handholds

Engineering Contradiction:

Improveconnection applicabilityVSAvoidconnection system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connection system is designed with universal applicability to work with various flotation device types, including those without handholds. The retractable line mechanism can accommodate different attachment points and configurations, increasing versatility without significantly complicating the system through standardized connection interfaces.

Inventive Principle:

Principle #6Universality (Multi-functionality)
