Adjustable Garment Elastic Layer Constraint Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing garments with adjustable sizes for children often require additional elements like buttons, which increase thickness, discomfort, and production costs, and are cumbersome to manufacture.
Innovation Solution
A garment with two layers of different elasticity, where a high elasticity first layer is joined to a low elasticity second layer in fastening zones, allowing the second layer to limit the extension of the first layer and be easily cut to increase size, reducing the need for additional elements and simplifying manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If buttons or similar elements are used to adjust elastic band width, then the trousers can be adjusted in size, but additional thickness is created causing discomfort
Solution Approach 1:
The invention removes buttons and other thick adjusting elements from the belt structure. Instead, it uses an elastic band with eyelets that can be directly attached to the belt loops or holes, eliminating the need for intermediate button elements that add thickness and discomfort.
Solution Approach 2:
Rather than using rigid buttons to hold the elastic band, the invention inverts the approach by making the elastic band itself the primary adjusting mechanism that can be directly secured to the belt structure without requiring thick intermediary elements.
2Adaptability or versatility
If buttons and through channels are added to the belt, then size adjustment is enabled, but production costs and processing time increase
Solution Approach 1:
The invention eliminates buttons and complex through-channel structures from the belt. The simplified design uses direct attachment of the elastic band to pre-formed belt loops or holes, removing multiple manufacturing steps and reducing production complexity.
Solution Approach 2:
The invention combines the functions of buttons, channels, and elastic band attachment into a single integrated elastic band system with eyelets, reducing the number of separate components and assembly steps required during manufacturing.
3Adaptability or versatility
If multiple elements like buttons and elastic bands are used, then size adjustment is achieved, but the device complexity increases
Solution Approach 1:
The invention removes unnecessary intermediate elements such as buttons, complex channel structures, and multiple attachment mechanisms. Only the essential elastic band with eyelets remains, directly interfacing with the belt loops or holes.
Solution Approach 2:
The elastic band with eyelets serves multiple functions simultaneously: it provides the adjustable sizing mechanism, acts as the attachment element, and replaces the need for buttons and complex channel structures, thereby reducing overall device 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
This solution allows for adjustable and progressive size adaptation without additional thickness, reducing production costs and discomfort, while enabling maximum extensibility of the first layer without the constraints of the second layer, facilitating growth and size adjustments.
Implementation Method 1
a first layer (12) having a first degree of elasticity or first yielding capacity, and a second layer (14) having a second degree of elasticity or second yielding capacity
Implementation Method 2
The second layer (14) can therefore prevent an extension of the first layer (12) between the first fastening zone (16) and the second fastening zone (18)

AI summary
The present disclosure concerns a garment (100, 200, 300) or a portion of a garment. The garment, or the garment portion, is of adjustable extension, size or dimension and includes a first layer (12) having a first degree of elasticity or first yielding capacity, and a second layer (14) having a second degree of elasticity or second yielding capacity, wherein the second degree of elasticity or second yielding capacity is less than the first degree of elasticity or first yielding capacity, respectively. The first layer is joined to the first layer in at least one first fastening zone (16) and a second fastening zone (18), and said second layer (14) is able to create a constraint or impediment of an extension of the first layer (12) between the first fastening zone (16) and the second fastening zone (18) which goes beyond a capacity of extension or yielding capacity of the second layer (14).
