Rope Organizers for Round Sling Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rope round slings are limited in their ability to lift increased loads for a given weight per length unit of load-bearing material, necessitating an improvement in their design to enhance load transfer efficiency between attachment points.
Innovation Solution
A rope assembly with a line forming multiple loops and organizers that maintain specific relationships between line segments, facilitating effective load transfer by maintaining parallel and non-crossing configurations under tension, thereby optimizing the distribution of load-bearing segments between attachment points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional rope structures are used, then the sling can be manufactured with simple construction, but the load bearing capacity per unit weight is limited
Solution Approach 1:
The rope is divided into multiple segments or loops, each contributing to load bearing. The organizers further segment the rope into functional sections (load-bearing segments vs. non-load-bearing segments), allowing optimized load distribution across multiple rope segments simultaneously, thereby increasing overall load capacity without proportional increase in total weight.
Solution Approach 2:
The invention transitions from a simple linear rope configuration to a multi-dimensional loop structure with organizers positioned at specific intervals. This creates spatial arrangement where rope segments operate in parallel load-bearing paths, effectively utilizing three-dimensional space to multiply load capacity beyond what a simple linear arrangement could achieve.
2Strength
If more load bearing material is added, then the lifting capacity increases, but the weight per length unit increases proportionally
Solution Approach 1:
By segmenting the rope into multiple loops with organizers, the system creates multiple load-bearing pathways. Each segment contributes to the overall lifting capacity, but the segmented architecture allows more efficient utilization of the total material weight, as load is distributed across segments rather than requiring a single heavier rope.
Solution Approach 2:
The organizers serve multiple functions: they maintain loop geometry, position load-bearing segments, and facilitate load transfer between segments. This multi-functionality means additional components (organizers) add structural efficiency and load capacity without requiring proportional increases in rope material weight.
3Ease of manufacture
If the rope structure is simplified, then manufacturing is easier, but load transfer efficiency between attachment points decreases
Solution Approach 1:
The segmented loop structure with organizers creates distinct functional zones that naturally guide load transfer. Each segment between organizers is designed to bear load in a specific manner, and the organizers themselves become standardized components that simplify the manufacturing process while ensuring consistent load transfer efficiency across all segments.

AI summary
A rope assembly that is adapted to extend between first and second attachment points comprises a line arranged to define a plurality of loops and at least one pair of organizers. The at least one pair of organizers is configured to engage the line such that line segments of the line between the at least one pair of organizers are maintained in a desired relationship with each other and such that the desired relationship facilitates transfer of loads through the rope assembly between the first and second attachment points.
