Boat Dock Mooring Spring Mechanism for Tide Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boat mooring systems fail to automatically adjust to wind and water conditions, leading to potential dock or pier collisions and inadequate protection against stress-induced damage.
Innovation Solution
A boat mooring system featuring a spring-like mechanism with a solid rubber bungee and dock line housed in a tube, allowing for automatic lengthening or shortening to maintain a safe distance from the dock, utilizing stainless-steel fasteners and customizable pipe dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If elastic synthetic mooring lines are used to secure boats, then the lines are easy to work with, but they are highly elastic and could break under high stress causing property damage or bodily injury
Solution Approach 1:
The patent changes the physical parameters of the mooring line by incorporating a spiral wire rope construction with embedded elastic elements, transforming it from a purely elastic synthetic line to a composite structure that maintains flexibility while dramatically increasing tensile strength and break resistance
Solution Approach 2:
The mooring line combines synthetic elastic materials with steel wire rope in a composite construction, where the spiral wire rope provides structural integrity and break resistance while the embedded elastic elements maintain ease of handling and shock absorption capabilities
2Reliability
If Mooring Whip systems with flexible poles are used to protect boats against dockside damage, then they can prevent boats from hitting the dock, but they require constant tension and become less effective when tides rise
Solution Approach 1:
The patent replaces the rigid flexible pole system with a dynamic spring mechanism that automatically adjusts its length and tension based on water level changes. The spring expands and contracts with tide variations, maintaining constant protective tension without requiring manual adjustment or losing effectiveness
Solution Approach 2:
The spring mechanism is self-regulating and automatically adapts to changing conditions. It maintains the boat at a safe distance from the dock through its inherent elastic properties, requiring no external control system or manual intervention to adjust for tide changes
3Reliability
If Mooring Whip systems are used to maintain safe distance from dock, then they can protect against dockside damage, but they do not sufficiently prevent boat from hitting dock under high winds or large wakes
Solution Approach 1:
The patent uses a composite construction combining the flexibility of synthetic materials with the high strength of spiral wire rope, creating a mooring line that can withstand high winds and large wakes while maintaining its protective function. The embedded elastic elements provide shock absorption during severe weather conditions
4Reliability
If thick ropes or mooring lines are used to secure boats to piers, then they can prevent free movement of the boat, but they require adjustment to compensate for rising and lowering sea levels due to tides
Solution Approach 1:
The patent replaces static mooring lines with a dynamic spring mechanism that automatically adjusts to tide levels. The spring expands when tides rise and contracts when tides fall, maintaining constant boat securing without requiring manual adjustment by the operator
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents boat collisions with docks or piers during adverse conditions by maintaining a consistent safe distance, reducing stress on the boat and adjusting for tides and winds.
Implementation Method 1
a spring-like mechanism that expands and contracts with the tide, wake, and wind. The spring-like mechanism comprises a solid rubber bungee
