Flexible Textile Belt Side Protection System for Construction Sites
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing side protection systems for construction sites are complex to install, pose safety risks due to frictional engagement, and require drilling or doweling into walls and ceilings, which is time-consuming and leaves cosmetic damage.
Innovation Solution
The use of flexible supports made of material like textile belts or ropes, which can be tensioned between wall or support elements without the need for screws or dowels, allowing for stepless length adjustment and secure attachment without drilling holes, enabling easy installation before ceiling concreting and reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid posts are used and fastened with screws and dowels, then the side protection system can be securely attached, but the installation becomes complex and time-consuming
Solution Approach 1:
The patent replaces rigid posts with flexible textile belts that wrap around support elements. These flexible carriers can be easily attached and adjusted without complex fastening mechanisms, significantly simplifying installation while maintaining secure attachment through friction and tension.
Solution Approach 2:
The patent substitutes the mechanical fastening system (screws, dowels, and their associated holes) with a friction-based tension system. The textile belts are tensioned around support elements to create secure attachment without penetrating fasteners, eliminating the need for drilling and complex assembly procedures.
2Ease of operation
If vertical posts are clamped between floor and ceiling using friction, then installation is simplified, but safety is compromised
Solution Approach 1:
The patent uses flexible textile belts that wrap around horizontal support elements (formwork beams, scaffolding pipes) to create secure attachment points. The flexibility allows the belts to conform to various support element shapes and sizes, ensuring reliable attachment without compromising safety.
Solution Approach 2:
The side protection system is installed on the ceiling side of the formwork before concrete pouring. The textile belts are attached to the formwork beams in advance, creating secure anchor points for the safety net system before the construction workers need to work at height.
3Reliability
If dowels and screws are used to attach safety elements to walls, then secure attachment is achieved, but cosmetic damage occurs and additional time is required
Solution Approach 1:
The patent replaces the penetration-based mechanical fastening system (dowels and screws requiring hole drilling and subsequent sealing) with a non-penetrating friction-based system. The textile belts wrap around support elements and are tensioned to create secure attachment without creating holes that require cosmetic repair.
4Adaptability or versatility
If flexible supports are used for length adjustment, then adaptability is improved, but attachment security may be reduced
Solution Approach 1:
The patent uses textile belts of various lengths that can be selected and tensioned around support elements. The flexibility of the belts allows them to accommodate different support element diameters and spacing, providing adaptability while the tensioning mechanism ensures secure attachment.
Solution Approach 2:
The patent employs textile belts with different lengths to accommodate various distances between support elements. By selecting the appropriate belt length and applying tension, the system adapts to different geometric configurations while maintaining secure attachment through the tensioning mechanism.
