Mobile Fall Protection Net System for High-Rise Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the construction industry, there is a need for a comprehensive fall protection system that can safeguard workers from falls of greater than 6 feet in all directions, particularly during high-rise building construction, as existing solutions often fail to provide complete protection against both inward and outward falls.
Innovation Solution
A fall protection system comprising an interior net slidably attached to column structures using clamps and hoisting blocks, allowing for horizontal and vertical mobility, with optional perimeter nets to catch falls away from the structure, and interior nets to catch falls within the structure, ensuring complete protection by absorbing falls without sagging excessively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed fall protection system is installed, then workers are protected from falls, but the system cannot be easily moved as construction progresses
Solution Approach 1:
The fall protection system employs dynamic attachment mechanisms including slideable clamps that can move along column flanges and hoisting blocks with cables that enable vertical repositioning. This allows the net system to maintain protective function while adapting to different construction stages and locations.
2Reliability
If the net is tightly attached to columns, then fall protection effectiveness is improved, but the net cannot be easily repositioned
Solution Approach 1:
The system uses dynamic attachment mechanisms including slideable clamps that can move along column flanges and hoisting blocks with cables that enable vertical repositioning. This allows the net system to maintain protective function while adapting to different construction stages and locations.
Solution Approach 2:
The fall protection system is divided into modular components including separate clamps, hoisting blocks, and net sections. This segmentation allows individual components to be independently adjusted, moved, or reconfigured without affecting the entire system, facilitating easy repositioning while maintaining protection effectiveness.
3Reliability
If a complete fall protection system covering all areas is installed, then worker safety is improved, but the system complexity increases
Solution Approach 1:
The clamp and hoisting block components serve multiple functions: they provide secure attachment to columns, enable easy repositioning along the structure, and support the fall protection net. This multi-functionality reduces the need for separate specialized components, simplifying the overall system while maintaining comprehensive safety coverage.
Solution Approach 2:
The fall protection system is divided into modular components including separate clamps, hoisting blocks, and net sections. This segmentation allows individual components to be independently adjusted, moved, or reconfigured without affecting the entire system, facilitating easy repositioning while maintaining protection effectiveness.

AI summary
A fall protection system is provided providing all protection for all workers in building erection. The system involves an interior net, and a perimeter net if needed. The net system may be both horizontally and vertically mobile, allowing it to be easily moved as building erection continues.
