Elastic Anchor Rope Cord Segment Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor ropes for small watercraft can damage the elastic core over time due to embedment of rope strands, and they often require a metal ring that can mar plastic surfaces.
Innovation Solution
A braided anchor rope with a tubular elastic core and cord segments that transfer tensile loads from the core to the rope, eliminating the need for an external metal ring and preventing direct engagement between the core and rope strands, which reduces damage and surface irregularities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the elastic core is directly engaged with the braided rope strands, then the rope structure is simple, but the core is damaged by embedment of rope strands over time
Solution Approach 1:
A cord segment is introduced as an intermediary element between the elastic core and the braided rope strands. The cord segment transfers tensile loads from the core to the rope, preventing direct engagement and embedment damage while maintaining structural integrity over time.
2Strength
If a metal ring is used to attach the elastic core to the rope, then the attachment is secure, but the metal ring can mar plastic surfaces
Solution Approach 1:
The invention replaces the durable but harmful metal ring with a cord segment that achieves secure attachment without causing surface damage. The cord segment is designed to be sufficiently strong for the application while being soft enough not to mar plastic surfaces.
3Reliability
If the elastic core is isolated from the braided rope strands using cord segments, then damage to the core is reduced, but the device complexity increases
Solution Approach 1:
The cord segments are integrated within the existing braided rope structure, with the elastic core nested within the braided rope and the cord segments connecting them. This nested arrangement provides protection without significantly increasing external complexity.
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
The solution effectively isolates the elastic core from rope strands, reducing damage and eliminating surface markings, while maintaining the rope's functionality for temporary mooring and retrieval of small watercraft.
Implementation Method 1
The elastic anchor rope comprises an elastomeric core, which stretches during mooring to permit discharge of persons and items such as on a beach with subsequent retraction of the craft to an offshore location
Implementation Method 2
cords for transferring tensile loads from the core to the rope

AI summary
An elastic anchor rope has an elastomeric core over most of its length. The core stretches during mooring to permit discharge of persons and items such as on a beach with subsequent retraction of the craft to an offshore location. A bow line permits retraction of the craft to the beach for loading purposes. Tensile loads are transferred from the elastomeric core to an intermediate cord and from the cord to end portions of the rope that do not have the core.
