Climbing Screen Support System with Sliding Mounting Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing climbing screen support systems pose risks of injury and damage due to the weight and alignment issues of climbing shoes, particularly during attachment and reattachment at heights, and manufacturing tolerances that lead to misalignment of edges between construction floors, hindering the free linear movement of rails.
Innovation Solution
A climbing screen support system comprising a support rail fixed to the construction surface with a mounting arm that is slidably secured to confine movement in a linear direction, allowing the climbing shoe to protrude from the edge by a predetermined distance, ensuring secure attachment and alignment with additional safety features like dual brackets and optional tethering for redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If climbing shoes are attached directly to attachment points embedded in the edge of a floor, then the climbing shoe can be securely mounted, but the climbing shoes become out of line due to manufacturing tolerances and edge misalignment, preventing free linear movement of the rail
Solution Approach 1:
The system divides the mounting function into two separate components: the support rail fixed to the construction and the mounting arm that attaches to the rail. This segmentation allows the rail to provide stable support while the mounting arm accommodates alignment variations through its connection mechanism, enabling both secure mounting and free linear movement.
Solution Approach 2:
The mounting arm acts as an intermediary between the support rail and the climbing shoe. It transfers the climbing shoe to the support rail, providing a buffer that absorbs misalignment caused by manufacturing tolerances and edge variations, thus enabling both secure attachment and linear movement capability.
2Strength
If climbing shoes are made substantial to withstand wind loading and screen weight, then the climbing screen can be securely supported, but the weight of the climbing shoe creates risk of serious injury or death if dropped onto workers or public below
Solution Approach 1:
The system separates the climbing shoe from the main support structure by introducing the mounting arm as an intermediate component. This allows the climbing shoe to be lighter since it only needs to attach to the mounting arm, while the substantial support rail fixed to the construction bears the main load of wind pressure and screen weight, reducing the hazard of falling heavy components.
Solution Approach 2:
The mounting arm serves as a mediator that connects the lighter climbing shoe to the substantial support rail. This intermediary arrangement allows the system to achieve the required strength to withstand wind loading and screen weight through the robust support rail, while the climbing shoe itself can be lighter, reducing the severity of potential falling object hazards.
3Reliability
If the mounting arm is secured remote from the edge of the construction, then safety is improved by reducing fall risk, but the climbing shoe cannot protrude sufficiently to engage the climbing screen rail
Solution Approach 1:
The mounting arm is designed with dynamic positioning capability, allowing it to be adjusted along the support rail to achieve the optimal protrusion distance. This dynamic adjustment enables the system to maintain safety by keeping the mounting mechanism secured remote from the edge while simultaneously achieving sufficient protrusion for the climbing shoe to engage the climbing screen rail effectively.

AI summary
A climbing screen support system comprising a support rail (2) fixable to a surface adjacent an edge of a structure; a mounting arm (6) slidably securable to the rail so as to confine movement of the mounting arm in a linear direction along the support rail; and a climbing shoe (7) attachable to an end of the mounting arm, wherein the support system is configured such that the mounting arm may be securely mounted to the support rail remote from the edge of the structure and subsequently slideable along the support rail such that the climbing shoe protrudes from the edge of the structure by a predetermined distance.
