Protective Cloth with Integrated Anchoring Tapes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective cloths for multi-purpose use, such as in building and vehicle repairs, often fail to adhere effectively to surfaces due to their lightweight electrostatically charged materials, leading to movement during use and potential damage from adhesive tapes which can leave residues on delicate surfaces.
Innovation Solution
A protective cloth with integrated flexible tapes that extend inside sleeves formed by folding and fixing opposite flaps of the sheet, using methods like heat-welding, sewing, gluing, or stapling, to ensure quick and secure anchoring to objects without damaging them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive tape is applied to fix the cloth to objects, then the cloth can be anchored to objects, but the adhesive tape can leave residual glue on the underlying object which cannot always be removed and is potentially harmful on delicate surfaces
Solution Approach 1:
The harmful adhesive function is extracted from the fixing mechanism. Instead of using adhesive tape that leaves residual glue, the patent uses mechanical fixing means (staples, clips, or tying) that attach to the cloth's integrated tapes without contacting the protected surface, thereby eliminating the harmful effect of residual glue while maintaining anchoring reliability
Solution Approach 2:
The patent introduces an intermediary fixing mechanism that mediates between the cloth and the object. The integrated tapes serve as intermediaries that can be mechanically fastened (with staples, clips, or knots) to hold the cloth in place without requiring adhesive contact with the protected surface, thus preventing glue residue damage while ensuring reliable anchoring
2Adaptability or versatility
If the cloth is made of lightweight electrostatically charged material, then the cloth is suitable for protective purposes, but the adhesion to objects is not guaranteed because of the lightness of the material
Solution Approach 1:
The cloth is segmented with integrated tapes attached at multiple strategic locations (opposite edges). This segmentation allows the lightweight electrostatically charged material to maintain its protective function while the distributed tape anchors provide cumulative mechanical attachment strength that compensates for the material's lightness, ensuring reliable adhesion without compromising versatility
Solution Approach 2:
The patent creates a composite structure combining the lightweight electrostatically charged protective material with integrated tapes made of different materials (fabric, plastic, or metal). This composite design leverages the electrostatic properties of the main cloth for protection while the tape materials provide enhanced mechanical anchoring capability, resolving the contradiction between lightness and adhesion reliability
3Reliability
If adhesive tape is used to fix the cloth, then the cloth can be anchored to objects, but the user takes some minutes to fix the cloth in the critical points
Solution Approach 1:
The tapes are integrated into the cloth during manufacturing rather than being applied separately during use. This preliminary action of pre-attaching tapes at critical locations eliminates the time-consuming process of selecting, positioning, and applying adhesive tapes during deployment, while ensuring reliable anchoring capability is built into the cloth structure from the start
