Adhesive Patch Hangtag for Outdoor Gear Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional patches for repairing fabric tears or cuts can weaken the material, and existing self-adhesive patches may lose adhesive properties over time, while also lacking decorative and informational functionalities.
Innovation Solution
A system comprising a patch hangtag with a removable adhesive patch made from the same material as the outerwear garment, allowing for easy repair and customization, and incorporating QR codes or branding for additional functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional patches are sewn or stitched onto fabric to repair tears or cuts, then the patch can be securely attached, but the item is weakened or degraded
Solution Approach 1:
The patent replaces the mechanical sewing/stitching system with a chemical adhesive bonding system. The patch includes an adhesive layer that bonds directly to the fabric, eliminating the need for needles, threads, and stitching holes that weaken the material. This substitution maintains secure attachment while preserving the integrity and strength of the original fabric.
Solution Approach 2:
The patent changes the bonding mechanism parameter from mechanical interlocking (stitches) to chemical bonding (adhesive). This parameter change allows the patch to be attached without creating physical holes or stress concentration points in the fabric, thereby maintaining the fabric's structural strength while achieving reliable patch attachment.
2Strength
If self-adhesive patches are used to mend fabric, then the item strength is maintained, but the adhesive properties are lost over time
Solution Approach 1:
The patent uses a composite material structure for the patch, combining a fabric layer with an adhesive layer. This composite construction provides both the structural integrity needed for strength and the adhesive properties needed for attachment. The combination of materials works synergistically to maintain both strength and reliable adhesive bonding over time, overcoming the limitation of single-material self-adhesive patches.
3Ease of repair
If patches are made from different materials than the garment, then the repair is functional, but the aesthetic is compromised
Solution Approach 1:
The patent applies homogeneity by making the patch material match the garment fabric material. Both the patch and the garment are constructed from the same fabric type, weight, and color, creating a visually seamless appearance. This material homogeneity maintains the aesthetic quality of the garment while providing full repair functionality, as the matching materials ensure proper texture, drape, and visual continuity.
