Vacuum Locking Structure for Apparel Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional articles of apparel and footwear lack a mechanism to lock the size or shape to a body part, making it difficult to achieve an optimum fit.
Innovation Solution
A locking structure comprising a bladder with a first and second barrier element defining a chamber, an elastic element, and locking elements with interface surfaces that transition between an unlocked and locked state by adjusting pressure within the bladder, allowing for a customizable fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional adjustable articles of apparel or footwear are used, then various sizes and fits can be accommodated, but the size or shape cannot be locked to a body part
Solution Approach 1:
The locking structure transitions between a relaxed state (allowing size adjustment) and a locked state (securing the fit). The elastic element and locking elements work together to dynamically change the structural properties of the article, enabling it to adapt to different body part sizes while maintaining a stable locked fit when engaged.
Solution Approach 2:
The article changes its physical parameters (shape, size, rigidity) by transitioning the locking structure between relaxed and locked states. When locked, the article's parameters are fixed to match the wearer's body part, providing a secure fit. When unlocked, the parameters can be adjusted for different sizes.
2Reliability
If a locking mechanism is added to achieve optimum fit, then fit stability is improved, but device complexity increases
Solution Approach 1:
The locking structure is divided into distinct functional components: a bladder for volume control, elastic elements for providing restoring force, and locking elements with interface surfaces for securing the fit. This segmentation allows each component to perform its specific function efficiently while keeping the overall design manageable.
Solution Approach 2:
The locking elements are disposed within the interior void of the bladder, creating a nested configuration. The elastic elements are also disposed within the interior void and attached to the bladder and locking elements. This nesting reduces the overall space required and simplifies the structure by integrating multiple components within the same volume.
3Adaptability or versatility
If the article is made flexible to accommodate various sizes, then adaptability is improved, but the ability to lock in a fixed shape is reduced
Solution Approach 1:
The article dynamically changes its flexibility and rigidity based on the state of the locking structure. In the relaxed state, the article remains flexible to accommodate various body part sizes. When the locking structure is engaged, the article transitions to a more rigid state, locking the shape to provide a stable fit.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the article to conform to the wearer's body, providing a secure and customizable fit while allowing for easy donning and doffing.
Implementation Method 1
at least one elastic element disposed within the interior void
Implementation Method 2
The interior void of the bladder is operable between a first pressure to move the locking system to a locked state and a second pressure to move the locking system to an unlocked state
