Wig Base with Artificial Skin and Net Layer for Natural Hairline
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wigs using V-tying or net bases often exhibit unnatural appearance due to visible needle feet or knots, which detract from the natural look and feel, especially at the hairline, making it difficult to create a seamless integration with the scalp.
Innovation Solution
A wig design featuring a dual-layer base structure with a first base member made of artificial skin and a second base member, such as a net member, where hairs are attached to the second base member and pulled through insertion holes in the first base member to create a natural-looking hairline without visible knots or needle feet, utilizing a hair fixing adhesive for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If V-tying is used to attach hairs to the artificial skin base, then the knot is not formed on the surface and hairs are relatively unrecognizable, but the needle foot becomes visible through the ultra thin artificial skin creating an unnatural appearance
Solution Approach 1:
The patent moves the hair attachment process from the surface dimension to the backside dimension of the artificial skin base. By attaching hairs to the backside and pulling them through to the surface, the needle feet are positioned on the backside where they are not visible, eliminating the unnatural appearance while maintaining the V-tying attachment method.
Solution Approach 2:
The patent inverts the conventional V-tying process by attaching hairs from the backside of the artificial skin base rather than from the surface. This inversion allows the needle feet to be hidden on the backside while the hairs emerge naturally at the surface, solving the visibility problem.
2Device complexity
If a single artificial skin base is used, then the structure is simple, but the hairline appearance is unnatural due to visible knots and needle feet
Solution Approach 1:
The patent divides the single artificial skin base into two functional layers: a first artificial skin base for providing a natural surface appearance, and a second attachment base for securing hairs. This segmentation allows the attachment process to occur on the second base while the first base maintains its natural, knot-free appearance at the hairline.
Solution Approach 2:
The patent introduces a second attachment base as an intermediary layer between the scalp and the hairs. This intermediary base handles the complex attachment function while the first artificial skin base maintains its simple, natural appearance, effectively separating the aesthetic function from the attachment function.
3Reliability
If hairs are pulled hard to prevent loosening, then the hair fixing is secure, but the needle foot contacts tightly to the backside of the artificial skin making it visible as a black line or spot
Solution Approach 1:
The patent relocates the needle foot from the surface dimension to the backside dimension of the artificial skin base. By pulling hairs through from the backside to the surface, the needle feet are positioned in the hidden backside region, eliminating visibility while maintaining the strong fixing effect of hard pulling.
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 solution provides a natural appearance and feel, with hairs appearing to grow directly from the scalp, reducing the visibility of knots and needle feet, thereby enhancing the wig's aesthetic quality and bulkiness.

AI summary
In a wig 10 comprising a wig base 11 and hairs 12 tied thereon, the wig base 11 is made with a base member 14 of artificial skin and a second base member 15 made of a net member provided on its backside, hairs 12 are knotted to the second base member 15, and inserted and pulled out from the lower side of the first artificial skin base member 14 to the surface side, thereby a wig 10 is obtained in which a needle foot is not formed on the backside of a wig base, and which has such natural appearance as if the hair 12 grows from skin pores, and excels in appearance.
