Elastic Strap Angled Hook and Loop Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elastic attachment straps face challenges with inflexible connection means, such as Velcro, which restrict adjustability and durability when the strap stretches, leading to weak connections that can easily separate during use.
Innovation Solution
The solution involves integrating elastic regions with inelastic connective regions, featuring spaced Velcro-type hook and loop fasteners angled along the strap's length, allowing for stretchability while maintaining connection strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Velcro-type loop and hook connection is used to connect the ends of the elastic strap, then the strap can be adjusted for tightness, but the connection becomes weak and pulls apart easily when the elastic stretches
Solution Approach 1:
The strap is divided into multiple segments: elastic regions that can stretch and inelastic connective regions with Velcro fasteners that remain stable. This segmentation allows the elastic portions to provide adjustability while the inelastic connective portions maintain strong, reliable connections that resist pulling apart during use.
Solution Approach 2:
Different regions of the strap are given different properties: the elastic regions are designed to be flexible and stretchable for adjustability, while the connective regions are made inelastic to provide stable, strong connections. This local differentiation resolves the contradiction by ensuring each region performs its specific function optimally.
2Ease of operation
If minimal amount of Velcro is used for connection, then the elastic strap can stretch with bending, but the adjustability of the strap is limited
Solution Approach 1:
The strap is divided into multiple segments: elastic regions that can stretch and inelastic connective regions with Velcro fasteners that remain stable. This segmentation allows the elastic portions to provide adjustability while the inelastic connective portions maintain strong, reliable connections that resist pulling apart during use.
Solution Approach 2:
The Velcro fasteners are arranged in a pattern that extends along the length of the strap rather than being concentrated at a single point. This dimensional distribution allows the strap to stretch and bend while maintaining multiple connection points for adequate tension adjustment.
3Adaptability or versatility
If short strips of Velcro are spaced out along the elastic strap, then more adjustability is provided, but the Velcro connections become weak and pull apart easily
Solution Approach 1:
The strap is divided into multiple segments: elastic regions that can stretch and inelastic connective regions with Velcro fasteners that remain stable. This segmentation allows the elastic portions to provide adjustability while the inelastic connective portions maintain strong, reliable connections that resist pulling apart during use.
Solution Approach 2:
Different regions of the strap are given different properties: the elastic regions are designed to be flexible and stretchable for adjustability, while the connective regions are made inelastic to provide stable, strong connections. This local differentiation resolves the contradiction by ensuring each region performs its specific function optimally.
4Adaptability or versatility
If Velcro-type fastener is used to connect the ends of the strap, then the strap can be adjusted, but the fastener inhibits the stretch of the elastic during use
Solution Approach 1:
The strap is divided into multiple segments: elastic regions that can stretch and inelastic connective regions with Velcro fasteners that remain stable. This segmentation allows the elastic portions to provide adjustability while the inelastic connective portions maintain strong, reliable connections that resist pulling apart during use.
Solution Approach 2:
The strap design allows dynamic behavior: the elastic regions can stretch and flex during use while the inelastic connective regions with Velcro fasteners remain stable. This dynamic differentiation enables the strap to be both adjustable and flexible during movement.

AI summary
An attachment strap created from an elastic strap capable of being stretched. The elastic strap is a continuous substrate forming a base of the attachment strap. A plurality of fastener sections attached to said strap, such that the fastener sections are spaced along the lengthwise direction of said strap and cross substantially the entire width of said strap. The fastener sections cross the width of the elastic strap at angles to the width of said strap. Also discussed is a method of manufacturing a flexible attachment strap which results in forming an elastic strap capable of being stretched. Per the method, a strap forms from a plurality of fastener sections having a fastener outer surface and a mounting inner surface and attaching said inner surfaces of fastener sections on said elastic strap. The mounted fastener sections form discrete fastening regions on the surface of the flexible attachment strap.
