Solution Overview

Problem

The underslung anchor windlass system on pontoon boats is obstructive when lifting the boat with a fork-lift, requiring removal due to potential damage or unsafe lifting, and is inconvenient for storage, especially when fasteners corrode or are difficult to access.

Innovation Solution

An anchor windlass system with a base mount permanently attached to the deck and a slidably received windlass mount, allowing the windlass assembly and bow roller to be conveniently removed as a unit, facilitating safe lifting and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the anchor windlass system is permanently fixed to the deck structure, then the installation is stable and secure, but the system cannot be removed when needed for lifting or storage

Engineering Contradiction:
Improveinstallation stabilityVSAvoidremovability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The anchor windlass system is divided into two main segments: a base mount that is permanently fixed to the deck structure, and a windlass mount that can be removed. This segmentation allows the system to maintain stable installation through the fixed base while enabling removal of the operational components when needed for lifting or storage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection between the base mount and windlass mount transitions from a static permanent connection to a dynamic removable connection. The windlass mount can be slidably received onto the base mount and then securely fastened when needed, or removed when not needed, providing adaptability while maintaining stability during use.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the windlass assembly is permanently attached to the deck, then it provides stable anchoring operation, but it obstructs fork-lift insertion and creates safety hazards during lifting

Engineering Contradiction:
Improveanchoring operation stabilityVSAvoidlifting operation safety
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The windlass assembly is extracted from the permanently fixed portion and placed on a removable windlass mount. This allows the operational components to be removed from the deck area before lifting operations, eliminating obstructions and safety hazards, while the base mount remains securely attached to provide stable reinstallation capability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If the anchor windlass system remains installed during storage, then no reinstallation is needed, but it is vulnerable to damage and requires complex removal procedures when lifting is needed

Engineering Contradiction:
Improvesystem protectionVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The windlass mount is designed with preliminary alignment features that guide it onto the base mount during installation. The sliding reception mechanism and fastener alignment are pre-configured to simplify the attachment process, making reinstallation after lifting operations straightforward rather than complex.

Inventive Principle:
Principle #10Preliminary action
