Adhesive Weighted Garment Tab for Hem Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for preventing garment hems from moving due to wind, such as weights attached to dresses or skirts, are often bulky, visible, or damage the fabric, and lack versatility and inconspicuousness.
Innovation Solution
A compact, smooth, and adhesive weighted garment tab with a circular steel disk coated in rubberized paint and a reusable fabric-safe adhesive, allowing secure attachment to various fabrics without visible interference, enabling multiple tabs to be discreetly applied around the hem.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If weights are attached to garment hems to prevent upward movement, then resistance to wind is improved, but the device becomes bulky and visible
Solution Approach 1:
The patent changes the physical parameters of the weight device by using a thin, flat disc shape instead of traditional bulky weights. The disc has a thickness of only 0.5-2mm and a diameter of 10-50mm, transforming it from a volumetric object to a planar object that is invisible when attached to the garment hem.
Solution Approach 2:
The patent applies color matching by providing the disc in various colors that can be selected to match the garment color. This makes the disc visually inconspicuous against the garment background, effectively hiding its presence while maintaining the wind resistance function.
2Force
If weights are attached to garment hems to prevent upward movement, then resistance to wind is improved, but the device becomes visible on the outer side of the hem
Solution Approach 1:
The patent provides the disc in various colors that can be matched to the garment color, making the disc visually blend with the garment and become invisible from the outside. This color matching principle directly addresses the visibility problem while maintaining the functional weight resistance.
Solution Approach 2:
The patent transitions the weight device from a three-dimensional bulky object to a two-dimensional thin disc. This dimensional reduction allows the weight to be attached flush against the garment hem, eliminating protrusion and visibility from the exterior while preserving the gravitational force function.
3Object-affected harmful factors
If clips are used to attach weights to avoid damaging the garment, then fabric damage is prevented, but the device becomes bulky and visible
Solution Approach 1:
The patent extracts and eliminates the separate clip attachment mechanism from the weight device. Instead of using a clip to attach the weight, the weight disc itself is made adhesive with a pressure-sensitive adhesive layer on its back surface, allowing direct attachment to the garment hem without any protruding mechanical fasteners.
Solution Approach 2:
The patent merges the attachment function with the weight disc by integrating a pressure-sensitive adhesive layer directly onto the back surface of the disc. This combines the weight function and the attachment function into a single integrated component, eliminating the need for separate clips or fasteners that would add bulk and visibility.
4Illumination intensity
If adhesive weights are used to attach to garment hems, then visibility is reduced, but the adhesive may damage fabric during removal
Solution Approach 1:
The patent specifies particular parameters for the pressure-sensitive adhesive including its thickness (0.1-1mm), tensile strength (0.5-5 MPa), and shear strength (1-10 MPa). These controlled adhesive parameters ensure sufficient bonding strength for attachment while allowing clean removal without fabric damage, resolving the contradiction between visibility reduction and fabric protection.
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
Effectively keeps garment hems in place without causing damage or discomfort, providing resistance to upward and sideways movements while being removable and reusable across different garments.
Implementation Method 1
a pressure-sensitive adhesive on the back surface of the disk
Implementation Method 2
The disk has a smooth, hard finish that does not catch onto or snag onto the fabric of the garment

AI summary
A weighted garment tab in the form of a weighted disk that has a fabric-safe and reusable adhesive on the back surface. The adhesive generally includes a cover or release member that protects it before application to the garment. This tab has a smooth, hard finish that does not catch onto or snag onto the dress fabric and is smaller, flatter, and smoother compared to the prior art devices mentioned above, so that it is much less noticeable to the wearer during use. Also, a method of preventing upward movement of a garment in an air current by applying one or more tabs onto the hem or lower portion of the inside of the garment.
