Elastic Apparel Strap with Perforations for Auxiliary Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional garment straps lack functional attributes and versatility, primarily serving as simple fabric or material strips for shoulder support, failing to provide decorative and functional enhancements.
Innovation Solution
A garment strap with elastic properties and strategically positioned perforations along its length, allowing for the insertion and retention of auxiliary items, such as beads or other decorative elements, to enhance both functionality and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a solid strip of fabric is used for the strap, then the strap provides basic shoulder support, but it lacks functional attributes and versatility
Solution Approach 1:
The strap is divided into multiple functional segments: elastic portions for stretching and adjusting, perforations for auxiliary attachments, and fabric sheaths for structural support. This segmentation allows each part to serve specific functions while maintaining overall simplicity.
Solution Approach 2:
The strap is designed to perform multiple functions: providing shoulder support, allowing length adjustment through elastic portions, enabling auxiliary attachments through perforations, and offering decorative customization. This multi-functionality resolves the contradiction by adding versatility without proportionally increasing complexity.
2Adaptability or versatility
If the strap is made elastic to allow stretching, then the perforation can be enlarged for auxiliary insertion, but the strap must maintain structural integrity
Solution Approach 1:
The strap uses composite construction combining elastic materials (spandex, elastane, rubber) with fabric sheaths (cotton, silk, lace). This composite structure provides both the elasticity needed for perforation adjustment and the structural integrity to maintain shape and support.
Solution Approach 2:
The fabric sheath acts as a flexible shell that encases the elastic strands, providing structural support and defining the strap's shape while allowing the elastic portions to stretch and contract for perforation adjustment.
3Adaptability or versatility
If multiple perforations are positioned along the strap length, then more auxiliary attachment options are provided, but the strap structure becomes more complex
Solution Approach 1:
Perforations are strategically positioned at specific locations along the strap where they provide maximum functional benefit. The fabric sheath structure is designed with localized openings that maintain overall strap integrity while providing specific attachment points, avoiding random or excessive perforations that would increase complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The elastic strap system enables the attachment of various auxiliaries to the garment, providing versatility in design and functionality, while the elastic properties ensure secure retention of the attached items, enhancing the wearer's options for style and coverage.
Implementation Method 1
The elastic strap can be stretched to enlarge the perforation and thereby enable the insertion of a solid item that is tethered to an auxiliary into the enlarged perforation. When the stretch is released, the enlarged perforation resumes an unstretched size to retain the solid item and its tethered auxiliary attached to the strap.

AI summary
A method of combining an auxiliary with a garment includes providing a garment that has an elastic strap attached to it, so that the garment and strap can cooperate to hold the garment in place on a person wearing the garment. The strap has a length with a perforation positioned along the strap length. Tension is applied to stretch the strap to enlarge the perforation, and a solid item that is tethered to an auxiliary is inserted into the stretched perforation. Releasing the tension on the strap so the enlarged perforation resumes an unenlarged size retains the tethered solid item and its tethered auxiliary attached to the strap.
