Protective Flaps for Surface Covering Strips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface covering devices face accelerated degradation of longitudinal strips and their beads due to severe abrasion and exposure to UV radiation and corrosive vapors, leading to short lifespan and frequent replacements.
Innovation Solution
The device incorporates flaps along its longitudinal edges that isolate the beads from the atmosphere and sun's rays, combined with a continuous locking system and high-strength materials like ultra-high molecular weight polyethylene fibers, to protect the strips from degradation and ensure secure anchoring during deployment and retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the longitudinal strips and bead are exposed to the atmosphere during deployment, then the covering device can be easily installed and operated, but the strips and bead degrade rapidly due to abrasion, UV radiation, and corrosive vapors
Solution Approach 1:
The patent employs a flexible protective flap made of durable material that extends along the longitudinal edges of the cover. This flap acts as a protective shell that can be positioned to shield the bead and longitudinal strip from environmental degradation while allowing the cover to remain flexible and easy to deploy. The flap is integrated into the cover structure, maintaining ease of operation while extending the lifespan of the longitudinal strips by protecting them from abrasion, UV radiation, and corrosive vapors.
2Strength
If high-strength materials like ultra-high molecular weight polyethylene fibers are used for the longitudinal strips, then the strips resist abrasion better, but the device complexity increases
Solution Approach 1:
The patent utilizes composite material construction for the protective flap, combining durable, abrasion-resistant materials with UV and chemical corrosion resistance. By integrating these specialized materials into a single protective component rather than requiring the entire longitudinal strip system to be made of high-strength materials, the solution achieves enhanced protection while managing device complexity. The flap acts as a sacrificial protective layer that shields the underlying longitudinal strip.
3Reliability
If the bead is continuously locked in the rail opening during deployment, then the cover remains securely anchored, but the bead is subjected to constant stress that accelerates degradation
Solution Approach 1:
The protective flap is positioned to provide beforehand cushioning and protection for the bead and longitudinal strip before they are subjected to operational stresses. By shielding these components from environmental degradation mechanisms (UV radiation, corrosive vapors, abrasion) during both deployed and retracted states, the flap reduces cumulative stress and degradation, thereby extending the lifespan of the bead while maintaining secure anchoring when the cover is deployed.

Function Achieved in This Case
The solution significantly extends the lifespan of the covering device by protecting the longitudinal strips from abrasion, UV radiation, and corrosive vapors, maintaining structural integrity and operational efficiency while reducing maintenance needs.
Implementation Method 1
to lock it by wedging it under the adjacent wing of the corresponding rail as the cover unwinds during the drum's translation in the first direction
Implementation Method 2
capable, when a portion of each bead is wedged under the adjacent wing of the corresponding rail, of isolating the portion of the longitudinal band corresponding to the wedged bead portion, either from the atmosphere prevailing between the inner face of the deployed portion of cover and the covered surface portion, or from solar rays

AI summary
The present invention relates to a device for covering a surface, which comprises: (a) a covering of which each longitudinal edge is provided with a longitudinal strip ending in a flap; (b) a rotatably mounted drum capable of winding or unwinding the covering, and movable on rails placed on either side of said surface; (c) a system for continuous locking / unlocking of the flap in the rails during the translation of the drum, in which the covering comprises at least one flap which makes it possible to isolate the portion of the longitudinal strip corresponding to the stuck flap portion, either from the atmosphere contained between the inner surface of the deployed covering portion and the covered surface portion, or from solar radiation.
