Clothing Clasp for Sleeveless Garment Strap Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sleeveless tops often have arm openings that are too large, making them unsightly for wear, and temporary adjustments are difficult for the average user to achieve without professional expertise or costly alterations.
Innovation Solution
A clothing clasp system comprising a rectangular frame member and insert member that can be attached to the shoulder strap of a sleeveless top, allowing the strap to be shortened by looping it through the frame and inserting the raised area of the insert member, which fixes the strap beneath the frame, thereby reducing the arm hole size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If permanent alterations are made to reduce arm opening size, then the fit is improved, but the cost and complexity increase due to requiring professional expertise
Solution Approach 1:
The clasp is divided into separate components (frame member, insert member, and strap) that can be independently manufactured and assembled. This allows the adjustment mechanism to be produced as a modular unit without requiring complex permanent alterations to the garment itself.
Solution Approach 2:
The clasp acts as an intermediary device between the user and the garment, providing the adjustment function without modifying the garment permanently. The strap loops through the frame member and is secured by the insert member, creating a temporary but effective adjustment mechanism.
2Ease of operation
If temporary adjustments are made to reduce arm opening size, then the ease of operation is improved, but the appearance deteriorates due to unsightly adjustments
Solution Approach 1:
The clasp is designed to be visually unobtrusive with a compact rectangular profile that blends with the strap. The frame member and insert member are sized to minimize visual impact while still providing effective adjustment, allowing the temporary nature of the adjustment to be aesthetically acceptable.
Solution Approach 2:
The insert member fits within the opening defined by the frame member, creating a nested structure that minimizes the overall profile. The strap loops through the frame and is secured by the insert, with all components contained within a compact space that does not protrude significantly from the strap.
3Area of stationary object
If the strap length is reduced using the clasp, then the arm hole size is reduced, but the strap length decreases
Solution Approach 1:
The clasp provides a dynamic adjustment mechanism where the strap can be looped through the frame member and secured at different positions using the insert member. This allows the user to adjust the effective strap length to achieve the desired arm hole size while maintaining the ability to modify the adjustment later.

AI summary
A clothing clasp for shortening the length of a strap of a sleeveless garment includes a frame member providing an opening therethrough and a cooperating insert member having a raised area that can fit in the opening when positioned beneath the frame member. A portion of the strap can be pushed downwardly through the opening to provide a loop, and the insert member can be positioned within the loop so that its raised area will extend upwardly in the opening and remain there with tightening of the strap and reduction of the loop.
