Removable Wall Barrier with Moveable Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barriers for construction workers on elevated positions fail to balance safety and accessibility, as they either allow falls or hinder the placement of precast wall sections due to fine mesh requirements, making it difficult to conduct necessary work.
Innovation Solution
A moveable barrier system with fixing means, including hinged or slidable portions, and telescopic extendibility, allowing secure access to the upper wall edge while preventing falls and loose object loss, featuring a perimeter frame with infill mesh for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fine mesh is installed on the barrier from top to bottom to prevent loose objects from falling, then safety is improved, but accessibility for conducting work on the upper edge of the wall deteriorates
Solution Approach 1:
The barrier is designed with moveable panels that can be shifted horizontally along the wall. This dynamic configuration allows workers to open sections of the barrier to access the upper edge of the wall for installing precast sections, while maintaining the fine mesh safety coverage in the closed positions. The barrier transitions between closed (safe) and open (accessible) states as needed.
Solution Approach 2:
The barrier is divided into multiple separate panels or sections that can be independently moved or opened. This segmentation allows specific portions of the barrier to be opened for work access while other portions remain closed to maintain safety and prevent object drops. Each panel can be independently positioned to balance safety and accessibility requirements.
2Reliability
If a barrier is installed on the upper edge of the wall to prevent falls, then worker safety is improved, but access to the upper portion of the wall for positioning precast sections deteriorates
Solution Approach 1:
The barrier incorporates moveable panels that can be horizontally shifted along the wall structure. When workers need to access the upper portion of the wall for positioning precast concrete sections, they can open or retract specific barrier panels to create clear access paths. When not in use, the panels return to their protective closed positions, maintaining fall prevention capabilities.
3Ease of operation
If spaced horizontal bars are used in the barrier to allow worker access, then ease of operation is improved, but the ability to prevent loose objects from falling deteriorates
Solution Approach 1:
The barrier system uses moveable panels that can be opened horizontally to provide worker access to the wall edge. When the panels are closed in their normal protective position, they form a solid continuous surface with integrated fine mesh, effectively preventing loose objects from falling while maintaining structural strength. The dynamic opening/closing action provides access without compromising object retention when closed.

AI summary
Aspects of this invention relate to a barrier for fixing to an portion of a wall. The barrier includes at least one plate that is securable to the wall. For each plate, there is a vertical upright attached to and extending upwardly from the plate to which the barrier is secured. The barrier is held by the vertical upright above the upper portion of the wall as required. removable from the vertical upright to allow access to the upper portion of the wall as required. In one aspect, at least a portion of the barrier is moveable relative to a remainder of the barrier and between a first portion, where it is located above an upper edge of the wall, and a second portion, where access is then provided to the upper wall edge above which the movable barrier portion was positioned.
