Adjustable Strap System With Dual Stretch And Sliding Coupler
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional garment straps have adjustable length but lack the ability to adjust stretch properties, leading to discomfort in certain applications.
Innovation Solution
A strap system with two straps in a face-sharing relationship, where one strap has higher stretch properties than the other, and a coupling mechanism that slides along the straps to adjust the overall stretch and length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional garment strap is used with fixed stretch properties, then the strap structure is simple, but the comfort and fit cannot be adjusted for varying tension forces
Solution Approach 1:
The strap system is divided into two separate straps (first strap and second strap) with different stretch properties. The first strap has higher stretch properties while the second strap has lower stretch properties. This segmentation allows each strap to perform its specific function optimally while together they provide adjustable overall stretch characteristics through the coupling mechanism.
Solution Approach 2:
The coupling mechanism is designed to be slidable along the length of the straps, allowing dynamic adjustment of the stretch properties. By moving the coupling mechanism to different positions, the user can change the effective stretch distance and adjust the tension distribution between the two straps, making the system adaptable to varying comfort requirements.
2Adaptability or versatility
If a single strap with fixed stretch is used, then the device complexity is low, but the ability to accommodate varying tension forces is limited
Solution Approach 1:
The system uses two separate straps instead of one, allowing independent optimization of stretch properties for each strap. The first strap is designed with higher stretch properties to accommodate high tension forces, while the second strap with lower stretch properties provides stability and support, together enabling comprehensive tension accommodation.
Solution Approach 2:
The coupling mechanism allows changing the effective parameters of the strap system by sliding along the straps. This adjusts the stretch distance and tension distribution, enabling the system to adapt to varying tension forces by modifying the active stretch parameters of the first and second straps in different configurations.
3Adaptability or versatility
If the coupling mechanism is positioned at different locations, then the stretch amount can be adjusted, but the device complexity increases
Solution Approach 1:
The coupling mechanism is designed as a simple slidable component that can be dynamically repositioned along the straps. This dynamic positioning allows users to adjust the stretch amount by moving the coupling mechanism to different locations, creating different effective stretch distances between the attachment points on the garment.
Solution Approach 2:
The coupling mechanism is designed to be easily adjusted by the user without requiring complex tools or procedures. The slidable design allows self-service adjustment of the stretch properties by simply moving the coupling mechanism along the straps to the desired position, making the adjustment process intuitive and user-friendly.

AI summary
Aspects herein are directed to a strap system having an adjustable stretch that is suitable for upper body garments, lower body garment, and articles such as bags, and articles of footwear. The strap system includes a pair of straps that are coupled together in a face sharing relationship by a coupling mechanism. One of the straps in the pair of straps has greater stretch properties than the other strap. A total stretch of the strap system is adjustable by moving the coupling mechanism along a length of the strap system.
