Modular Roof Fall Protection Using Existing Building Substructures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fall protection systems for buildings, particularly on roofs, are complex, costly, and require significant effort to install and dismantle, while also restricting the use of the building and often necessitate additional substructures.
Innovation Solution
A modular fall protection system utilizing vertical struts and crossbars attached to existing substructures like profile rails, allowing for easy installation and dismantling without additional substructures, leveraging existing infrastructure such as solar system profiles for stability and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional scaffolding systems are installed for fall protection, then reliable fall protection is achieved, but the system becomes complex, costly, and requires significant effort to install and dismantle
Solution Approach 1:
The fall protection system is divided into modular components: vertical braces that attach to existing substructure, horizontal braces that connect vertical braces, and optional safety net support. This segmentation allows easy assembly and disassembly while maintaining reliability, directly resolving the contradiction between reliable protection and system complexity
Solution Approach 2:
The system is designed to attach to various existing building substructures (roof trusses, walls, solar panel mounting structures) making it universally applicable across different building types. This multi-functionality reduces the need for specialized complex structures while maintaining fall protection reliability
2Reliability
If traditional scaffolding systems are installed for fall protection, then fall protection is provided, but significant material and effort are required for installation and dismantling
Solution Approach 1:
The system leverages existing building substructures that have already been installed as part of the building construction or solar panel mounting. By utilizing these pre-existing structures as attachment points, the invention eliminates the need to install additional heavy substructure, significantly reducing material usage while maintaining fall protection reliability
Solution Approach 2:
The modular braces and connectors can be easily disassembled and reused for other fall protection installations. This recoverability reduces overall material consumption across multiple installations while maintaining reliable protection
3Reliability
If complex fall protection systems are installed, then safety is improved, but the building functionality is restricted
Solution Approach 1:
The system is designed to be temporary and removable, allowing the building to dynamically switch between protected construction phases and full operational use. The modular components can be quickly installed when needed and removed when construction is complete, maintaining both safety and building adaptability
