Wall Bracket with Adjustable Platform and Integrated Fall Arrest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scaffolds resting on the ground are slow to assemble and disassemble, require large ground contact for stability, and separate J-hooks for fall arrest often interfere with work, limiting versatility for different construction tasks.
Innovation Solution
A wall bracket system with a support structure fastened to a wall, allowing a working platform frame to adjust in height and include integrated fall arrest features, eliminating the need for separate ground-based fall arrest systems and enhancing versatility for various construction tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional scaffolds rest on the ground, then stability is achieved through large ground contact area, but assembly and disassembly become slow and require ground leveling
Solution Approach 1:
The invention extracts the scaffold support from the ground and relocates it to the wall structure. The bracket system fastens to wall elements, removing the need for ground contact and ground leveling operations, thereby reducing assembly time while maintaining stability through wall attachment
Solution Approach 2:
The wall bracket serves as an intermediary structure between the wall and the working platform. This mediator transfers the load from the platform to the wall, eliminating the need for ground contact while providing stable support through the bracket-wall connection
2Reliability
If separate J-hooks are used for fall arrest, then safety compliance is achieved, but the J-hooks interfere with working operations
Solution Approach 1:
The invention merges the fall arrest function with the bracket structure itself. The horizontal beam and support structure integrate fall arrest capabilities into the primary working platform, eliminating separate J-hooks and preventing interference with working operations while maintaining safety compliance
Solution Approach 2:
The bracket structure serves multiple functions simultaneously: it provides the working platform support, enables height adjustment for different work phases, and incorporates fall arrest capabilities. This multi-functionality eliminates the need for separate fall arrest devices and maximizes working space accessibility
3Adaptability or versatility
If the bracket structure is designed for different heights and work phases, then versatility is improved, but structural complexity increases
Solution Approach 1:
The bracket structure is segmented into modular components including the vertical support, horizontal beam, and adjustable platform elements. This segmentation allows different parts to be independently configured for various heights and work phases while maintaining overall structural simplicity through standardized connection mechanisms

AI summary
The invention relates to a wall bracket for facilitating construction work. The wall bracket comprises a support structure (110) to be fastened to a wall (12), and a bracket structure (120) to be placed to rest on the support structure as a working surface and fall arrest for a person (30) or another load. The bracket structure to be placed to rest on the support structure (110) to be fastened to a wall comprises a working platform frame (150) which forms at least two different height positions and is provided with an upper support (152) and a lower support (154) for at least partly non-superimposed working platforms (152a, 154a).
