Liquid Barrier Device for Wig Adhesive Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for wig installation using adhesives result in limited longevity due to degradation from contact with liquids during everyday activities like bathing or showering, leading to premature removal of the wig.
Innovation Solution
A device designed to circumscribe the human head with a liquid-resistant inner surface, featuring different materials for enhanced friction and sealing properties, which forms a barrier between the scalp and the adhesive, preventing liquid contact and extending the wig's wear duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive is used to attach the wig to the head, then the wig can be securely attached, but the adhesive degrades over time due to contact with liquid during bathing or showering
Solution Approach 1:
The patent introduces a liquid barrier device as an intermediary between the adhesive and water/liquid contact. This barrier layer prevents direct contact between degrading liquids and the adhesive, thereby maintaining attachment strength while extending the duration of the wig installation. The barrier device acts as a mediator that allows the adhesive to function without exposure to harmful liquids.
Solution Approach 2:
The patent employs a flexible barrier device in the form of a thin film or shell that wraps around the head to create a protective seal. This flexible structure conformally adheres to the head shape while preventing liquid penetration to the adhesive layer, thus preserving both the attachment strength and extending the wear duration of the wig installation.
2Duration of action of stationary object
If a liquid barrier device is added to protect the adhesive, then the longevity of the wig installation is improved, but the device complexity increases
Solution Approach 1:
The barrier device is designed to perform multiple functions simultaneously: it creates a liquid barrier to protect the adhesive, provides structural support for the wig, and can be integrated with the wig construction itself. By combining these functions into a single component, the patent extends wig installation longevity without proportionally increasing device complexity.
Solution Approach 2:
The patent integrates the liquid barrier function within the existing wig construction layers, nesting the protective barrier within the wig's structural components. This nested approach allows the barrier to function within the existing system architecture without requiring separate, complex external devices, thus extending longevity while minimizing added 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 device effectively prevents liquid from reaching the wig's adhesive, thereby increasing the longevity of the wig installation by forming a substantial liquid-resistant seal and securing the device in place without pulling on the wig.
Implementation Method 1
The first inner surface portion may be configured to form a substantially liquid-resistant seal between the scalp of the head proximate to a hairline of the head
Implementation Method 2
The releasable fastener may be configured to fasten the first end portion to the second end portion such that the device may be configured to circumscribe the human head when the fastener fastens the first and second end portions
Implementation Method 3
The first material may comprise a material with a first coefficient of friction when placed against the scalp of the head and the second material may comprise a second coefficient of friction, lower than the first coefficient of friction when placed against a wig

AI summary
Devices and methods for improving the longevity of a wig installation include a device sized and configured to circumscribe a human head that is used to substantially prevent a liquid from contacting the periphery of an installation of a wig on a human head when the device is circumscribing the human head. A bottom portion of an inner surface of the device is configured to cover at least a portion of an adhesive used in the wig installation.
