Detachable Reinforcement Part for Rope Eye Stress Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The direct contact between a rope eye and a bolt in existing cable connections leads to localized stress and friction, reducing the service life of the rope, especially when a stop element is passed through the cable eye, causing power transmission over a small area and potential relative movement.
Innovation Solution
A reinforcement part is inserted into the cable eye, with a holding element detachably connected to the reinforcement part, allowing power transmission over a larger section and enabling the cable eye to be protected from excessive loads, and allowing the reinforcement part to be easily detached for passing through narrow openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reinforcement piece is inserted into the rope eye to distribute force transmission over a larger section, then the service life of the rope is improved and stress is reduced, but the rope eye cannot be passed through narrow openings without removing the reinforcement
Solution Approach 1:
The solution divides the reinforcement structure into two separable components: the reinforcement piece (which distributes stress) and the retaining element (which holds the reinforcement in place). This segmentation allows the reinforcement to be removed from the rope eye when needed, enabling passage through narrow openings while maintaining stress distribution benefits during operation
Solution Approach 2:
The retaining element is designed to be detachable, transforming the reinforcement structure from a static permanent installation to a dynamic configurable system. This allows the system to switch between two states: assembled (for stress distribution and reliability) and disassembled (for passage through narrow openings)
2Device complexity
If the rope eye rests directly on a bolt of the anchor element, then the structure is simple, but the force transmission is limited to a small area creating high localized friction and strain on the rope
Solution Approach 1:
The reinforcement piece acts as an intermediary element between the rope eye and the bolt. Instead of direct contact, the reinforcement piece receives the force from the bolt and distributes it across a larger surface area of the rope eye, reducing localized stress and friction while maintaining structural simplicity
3Ease of operation
If the retaining element is detachably connected to the reinforcement member to allow easy assembly and disassembly, then the ease of operation is improved, but the device complexity increases due to the additional connection mechanism
Solution Approach 1:
The retaining element is designed as a separate, extractable component that can be easily removed from the reinforcement piece. This extraction design simplifies the connection mechanism by using a simple insertion/removal interface rather than complex fastening systems, allowing tool-free assembly and disassembly while minimizing added 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 distributes stress evenly across a larger section of the cable eye, reducing friction and extending the service life of the rope while allowing easy passage through narrow openings without tools, ensuring reliable guidance and reduced operational stress.
Implementation Method 1
The detachment can involve elastic deformation of the retaining element. The deformation force can be dimensioned such that it can be applied manually or using a simple lever.
