Scaffolding Tie Loop Fastening for Quick Secure Tarpaulin Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scaffolding ties are costly due to the need for long elastic cords, inconvenient to use as they require multiple windings for tensioning, and often lead to loose connections and time-consuming disengagement, posing safety risks and increasing waste.
Innovation Solution
A scaffolding tie with a ligament biased towards a connected configuration, featuring complementary interconnection structures with sliding rails and registration formations for tactile feedback, allowing quick and secure attachment to scaffolding poles and tarpaulins, and enabling easy decoupling via a separate fastening means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a long elastic cord is used to enable the hook to loop around the scaffolding pole, then the tie can securely connect the tarpaulin to the pole, but the cost of the tie increases and the operation becomes more time-consuming
Solution Approach 1:
The elastic cord is segmented into multiple loops of decreasing size, with each loop designed to fit around the scaffolding pole. This eliminates the need for multiple windings while maintaining secure connection, as the segmented structure provides multiple attachment points along the pole circumference.
Solution Approach 2:
The cord is pre-configured with loops at specific intervals before use. This preliminary arrangement of the cord structure allows the scaffolder to simply attach the hook to the appropriate loop rather than winding the cord during installation, saving time while ensuring proper tension and security.
2Reliability
If the cord is wound multiple times around the scaffolding pole to achieve sufficient tension, then secure retention is achieved, but the operation becomes inconvenient and compromises safety
Solution Approach 1:
The cord is divided into discrete loops rather than a continuous long cord. Each loop is pre-sized to provide the necessary tension when attached to the pole, eliminating the need for multiple windings and constant force application by the scaffolder.
Solution Approach 2:
The patent describes a disposable tie where the cord is pre-configured with loops and the entire assembly is discarded after use. This eliminates the need for complex tensioning operations and allows simple attachment to any loop, prioritizing ease of operation over reusability.
3Adaptability or versatility
If the hook is allowed to slip along the cord to achieve proper positioning, then the tie can accommodate different pole positions, but the connection becomes loose and may disengage
Solution Approach 1:
The cord is segmented into fixed-size loops at predetermined intervals. The hook can be attached to different loops to accommodate varying pole positions, but once attached, the loop structure prevents slipping that would lead to loosening or disengagement.
Solution Approach 2:
The loops are designed with sufficient length and elasticity to provide adaptability for position adjustment, while the segmented structure ensures that the hook remains securely positioned once attached, preventing excessive movement that would compromise connection stability.
4Loss of time
If the cord is cut to achieve quick release of the tarpaulin, then disengagement time is reduced, but material waste increases and cost increases
Solution Approach 1:
The cord is segmented into loops with a detachable connection mechanism. This allows the hook to be quickly released from the cord without cutting it, enabling reuse of the cord while maintaining fast disengagement capability.
Solution Approach 2:
Instead of cutting and discarding the entire cord, the patent enables selective detachment of the hook from the cord. The cord can be recovered and reused on subsequent tarpaulins, reducing material waste while maintaining quick release functionality.
