Polymeric Barrier Material for Scaffolding Graphic Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional containment barrier materials used in scaffolding, such as shade cloth and wire mesh, are prone to ink fading due to the open weave structure allowing strands to move and rub against each other, causing printed graphics to lose definition and fade over time.
Innovation Solution
A barrier material comprising three layers of polymeric material with a diagonal lattice structure encapsulated in PVC, providing a static display surface that retains printed images, combined with a reinforcing grid structure to maintain structural integrity and reduce wind loading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If an open weave structure is used to allow wind penetration and reduce wind loading, then wind resistance is reduced, but the printed graphic fades and loses definition over time
Solution Approach 1:
The barrier material is divided into two distinct portions: a first portion with an open weave structure for wind penetration and a second portion with a tighter weave for graphic retention. This segmentation allows each portion to optimize its specific function while working together as a unified material system.
Solution Approach 2:
Different portions of the barrier material have different weave densities tailored to their specific functions. The first portion has a more open structure optimized for wind resistance, while the second portion has a tighter structure optimized for retaining printed graphics, creating local quality variations within the same material.
2Reliability
If a tighter weave structure is used to retain printed graphics, then graphic retention is improved, but wind loading increases
Solution Approach 1:
The barrier material is divided into two distinct portions: a first portion with an open weave structure for wind penetration and a second portion with a tighter weave for graphic retention. This segmentation allows each portion to optimize its specific function while working together as a unified material system.
Solution Approach 2:
Different portions of the barrier material have different weave densities tailored to their specific functions. The first portion has a more open structure optimized for wind resistance, while the second portion has a tighter structure optimized for retaining printed graphics, creating local quality variations within the same material.
3Ease of operation
If individual strands are allowed to move freely to provide flexibility, then material flexibility is improved, but printed ink is brushed away and fades
