Retractable Boat Cleat Assembly Corrosion Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retractable boat cleats made of metal are prone to corrosion and wear, leading to premature failure, water leakage, and operational issues due to contact with saltwater and size changes.
Innovation Solution
The use of a movable cleat assembly with corrosion-proof materials, such as nylon, for the tubes and bushings, along with a separate face plate and support base, and a drain system to direct water away from the assembly, minimizing corrosion and wear, and providing a secure, water-tight seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal materials are used for the cleat assembly, then strength and durability are improved, but corrosion and wear resistance deteriorate
Solution Approach 1:
The patent applies composite materials by combining metal components (for strength) with corrosion-resistant materials such as plastic or nylon (for corrosion protection). Specifically, the tubes are made of corrosion-resistant material while the cleat assembly incorporates metal face plates and support structures, creating a composite construction that achieves both strength and corrosion resistance simultaneously.
2Strength
If metal tubes are used to guide the legs, then structural integrity is improved, but water leakage and corrosion increase
Solution Approach 1:
The tubes are specifically made of corrosion-resistant material such as plastic or nylon instead of metal, creating a composite structure where the non-metallic tubes provide both structural integrity and resistance to water leakage and corrosion. This material substitution resolves the contradiction between needing strong structural support and avoiding water-related deterioration.
3Ease of operation
If the cleat is made retractable, then safety and appearance are improved, but complexity of the assembly increases
Solution Approach 1:
The retractable cleat assembly is divided into separate functional components: a stationary support base with tubes, a movable cleat body with legs, and connecting elements. This segmentation allows the cleat to retract into the support base while keeping the overall structure relatively simple. The separation of functions (support vs. movable gripping elements) reduces complexity compared to a fully integrated design.
4Ease of repair
If separate face plate and support base are used, then ease of assembly and repair are improved, but device complexity increases
Solution Approach 1:
The face plate and support base are designed as separate, modular components that can be independently manufactured, assembled, and repaired. The support base contains the tubes and mounting structure, while the face plate holds the cleat mechanism. This modular segmentation enables easier repair and replacement of individual components without replacing the entire assembly, offsetting the increased device complexity through improved maintainability.

AI summary
A movable cleat assembly is provided. The movable cleat includes a support base, a face plate positioned adjacent the support base and a retractable cleat. The retractable cleat includes a handle portion and at least one leg extending through the support base and the face plate. The face plate further includes an edge that is adapted to deform or otherwise embed a portion of itself into a boat when installed. At least one of the support base and face plate includes at least one tube to receive the leg therein. The at least one tube is composed of a corrosion-proof material.
