Pole Climbing Fall Restriction Assembly with Loop Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pole climbing fall restriction assemblies often lack a comfortable grip due to insufficient strap length or interference from connection hardware, making it difficult for users to securely hold the assembly while ascending or descending.
Innovation Solution
A pole fall restriction assembly featuring an elongated outer strap with a looped handle attached to one end, providing a comfortable grip and improved ergonomics, along with an adjustable inner strap and connector assembly for secure attachment to a body harness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection hardware (D-ring) is placed in the vicinity of where a grab would be located, then the assembly structure is compact and secure, but it interferes with a comfortable grip
Solution Approach 1:
The assembly is divided into distinct functional segments: the connection hardware (D-ring) is separated from the grip area by positioning it at one end of the outer strap, while the grab handle is positioned at the opposite end. This segmentation eliminates interference between the attachment mechanism and the user's hand, allowing both secure connection and comfortable gripping to occur simultaneously without spatial conflict.
2Device complexity
If strap length is reduced to provide compact assembly, then device complexity is reduced, but sufficient material for grabbing is lost
Solution Approach 1:
A looped handle is introduced as an intermediary element between the outer strap and the user's hand. This handle serves as a dedicated gripping interface that requires minimal strap length while providing excellent grab capability. The handle acts as a mediator that translates the structural constraints of the compact assembly into an ergonomic solution, allowing users to grip securely without needing extensive strap material.
3Ease of operation
If strap length is increased to provide sufficient material for grabbing, then comfortable grip is enabled, but device complexity and material usage increase
Solution Approach 1:
The looped handle serves as a material-efficient intermediary that provides superior grip capability without requiring increased strap length. By concentrating the gripping function into this dedicated handle element, the design achieves excellent ease of operation while minimizing the quantity of strap material needed, thereby resolving the contradiction between operational comfort and material usage.

AI summary
A fall restriction assembly for use by a pole climber/the assembly includes an elongated outer strap having first and second opposite ends, an inner strap/lanyard adjustably connected to the outer strap and that includes a connector for interconnecting it to a body belt worn by the pole climber; an adjustable connector assembly interconnecting the inner strap/lanyard to the outer strap; and a looped handle connected to the first end of the outer strap.
