Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current adhesive tapes used in athletic wear and clothing lose structural integrity and functionality due to their inability to maintain elasticity, as they do not revert to their original position after stretching, compromising the effectiveness of stretchable fabrics.
Innovation Solution
A multi-layered composite garment material incorporating a functionalized adhesive sheet with 3D embossed structures that can exert stretching forces and integrate with fabric layers, maintaining or enhancing the elasticity and structural integrity of the fabrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive tapes are used to bind fabric layers, then the fabric layers are bound together, but the adhesive tapes lose structural integrity and elasticity after stretching
Solution Approach 1:
The adhesive sheet is segmented into multiple discrete 3D adhesive structures (protrusions) distributed across the sheet surface. Each protrusion acts as an independent bonding unit that can deform and recover elastically, allowing the adhesive sheet to maintain overall structural integrity while accommodating fabric stretch and recovery movements.
Solution Approach 2:
The adhesive structures transition from a 2D flat adhesive layer to 3D protruding structures with height dimension. This dimensional change allows the adhesive to engage fabrics in both planar contact and vertical compression, providing multi-directional bonding that maintains effectiveness during fabric deformation and recovery cycles.
2Strength
If adhesive tapes are used to bind fabric layers, then the fabric layers are bound together, but the adhesive tapes do not revert to original position after stretching
Solution Approach 1:
The adhesive structures are designed with dynamic mechanical properties that allow them to deform elastically during fabric stretching and automatically revert to their original configuration when the fabric returns to its initial state. This dynamic response ensures continuous binding effectiveness through multiple stretch-recovery cycles.
Solution Approach 2:
The adhesive structures utilize changes in physical parameters (deformation, compression, elasticity modulus) to adapt to fabric movement. The material properties are selected to enable reversible deformation within a specific range, allowing the adhesive to accommodate stretching while maintaining position stability and returning to original position after each cycle.
3Reliability
If 3D embossed structures are added to adhesive sheet, then elasticity and structural integrity are maintained, but the device complexity increases
Solution Approach 1:
The 3D embossed structures are integrated into a thin adhesive film substrate, creating a lightweight and flexible composite structure. The thin film base provides flexibility and conformability to fabric surfaces, while the embossed protrusions add the necessary elastic recovery capability without significantly increasing overall thickness or complexity.
Solution Approach 2:
The adhesive sheet combines different material properties by integrating embossed 3D structures (providing elastic recovery) with an adhesive matrix (providing bonding). This composite approach allows each component to contribute its specific function, achieving both elasticity retention and binding strength while managing overall structural complexity through material integration rather than separate components.
