Fall-Protection Rope Holder for Easy Retrofit Cable Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rope systems for fall protection require the rope to be threaded through tubular components, making installation and replacement cumbersome and potentially damaging to the system.
Innovation Solution
A holder design featuring half-tubes that surround the rope and are inserted into guide grooves, allowing easy attachment and detachment without threading the rope through the holder, enabling secure and efficient installation and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rope is threaded through tubular components of the holder, then the holder can be securely attached to the rope, but the installation becomes cumbersome and potentially damaging to the rope system
Solution Approach 1:
The holder is divided into separate components: a body portion that attaches to the substrate and a distinct securing portion that interacts with the rope. This segmentation allows the holder to be installed by first attaching the body to the substrate, then separately securing the rope through guide grooves, eliminating the need to thread the rope through tubular components and simplifying the installation process while maintaining secure attachment.
2Reliability
If the rope is threaded through tubular components, then the holder can be firmly secured, but the rope may be damaged during installation and replacement
Solution Approach 1:
The tubular component that was previously used to secure the rope is extracted and replaced with guide grooves formed directly in the holder body. The rope is guided through these grooves rather than being threaded through a separate tubular component, eliminating the potential for damage during installation and replacement while maintaining firm securing of the holder to the substrate.
3Stability of the object's composition
If the holder is rigidly attached to the substrate, then stable fall protection is achieved, but the holder cannot be easily detached or replaced
Solution Approach 1:
The attachment mechanism to the substrate is designed to provide stable attachment during normal use while allowing for controlled detachment. The holder can be securely fastened to the substrate through appropriate mounting methods, yet can be easily detached and replaced when maintenance or replacement is needed, balancing stability with ease of repair.

AI summary
The invention relates to a holder (10) for a rope (12) of a rope system (14) for securing persons against falls, comprising a base (16); a first guide channel (18) for the rope (12) having a first longitudinal slot (20); a second guide channel (22) for the rope (12) having a second longitudinal slot (24); wherein the first and the second guide channels (18, 22) are aligned with respect to a longitudinal axis (A) on the base (16) such that a gap (32) is formed between the first and the second guide channels (18, 20); the first longitudinal slot (20) is rotated relative to the second longitudinal slot (26) with respect to the longitudinal axis (A) by an angle which is at least about 90° and at most about 270°. The invention also relates to a rope system for securing persons against falls, a method for inserting a rope into such a holder and a securing element (34) for such a holder.The invention enables the rope to be inserted into the holder easily and, in particular, subsequently.
