Wig Cap Assembly Using Transparent Polysiloxane Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wigs are uncomfortable due to extra thicknesses and visibility of connection zones, leading to itching and aesthetic issues, and require lengthy and costly production processes.
Innovation Solution
A wig design featuring a cap assembled from light fabric pieces with a thin, flexible, and transparent assembly strip that overlaps the edges of monofilament and tulle, providing a flat and almost invisible connection zone with an anti-slip coating for improved comfort and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple fabrics are assembled to form the cap, then the cap can cover different cranial zones, but extra thicknesses and visible connection zones are created causing discomfort and aesthetic issues
Solution Approach 1:
The patent uses a monofilament fabric with very fine mesh that is translucent and allows cutaneous respiration. This thin film structure replaces traditional thick fabric assemblies, eliminating extra thickness while maintaining coverage of the vertex area and allowing skin breathing.
Solution Approach 2:
The patent applies different fabric types to specific cranial zones: tulle for frontal, temporal and occipital areas, and monofilament for the vertex area. This local differentiation allows each zone to be covered by the most appropriate material while minimizing overall thickness and visibility.
2Reliability
If traditional sewing and folding methods are used to connect monofilament and tulle, then the connection is secure, but the connection zones become visible and uncomfortable
Solution Approach 1:
The patent uses a transparent or translucent assembly strip that matches the visual properties of the surrounding monofilament and tulle fabrics. This makes the connection zone practically invisible, eliminating the aesthetic drawback of visible seams while maintaining secure connection.
Solution Approach 2:
The patent introduces a transparent assembly strip as an intermediary element between the monofilament and tulle fabrics. This mediator provides a secure mechanical connection while being visually imperceptible, thus hiding the connection zone rather than exposing it.
3Reliability
If multiple fabric layers and strips are used for assembly, then the cap is secure and functional, but the production process becomes lengthy and costly
Solution Approach 1:
The patent combines multiple functions into the transparent assembly strip: it serves as a mechanical connector, a visual concealer, and a structural support element. This consolidation reduces the number of separate components and assembly steps, thereby shortening production time and reducing costs.
Solution Approach 2:
The transparent assembly strip performs multiple functions simultaneously: connecting different fabrics, providing structural support, concealing seams, and potentially providing anti-slip properties. This multi-functionality eliminates the need for separate components for each function, streamlining production.
4Reliability
If traditional non-transparent assembly strips are used, then the connection is secure, but the connection zones remain visible affecting aesthetics
Solution Approach 1:
The patent specifies that the assembly strip should be transparent or translucent, matching the visual properties of the surrounding fabrics. This optical property change makes the connection zone practically invisible while maintaining the mechanical security of the connection.
Solution Approach 2:
The transparent assembly strip acts as an intermediary that provides secure mechanical connection between fabrics while being visually imperceptible. This mediator element resolves the contradiction between secure connection and aesthetic invisibility.

AI summary
The wig has a hat or internal support in which natural or artificial hairs are implanted and formed by assembling fine meshed lightweight fabric pieces (2, 3). Adjacent edges of the lightweight fabric pieces are assembled by a flexible material and transparent or translucent thin strip (6) covering and overlapping the edges by forming a flat assembly area (7). An outer surface of the flexible material and transparent or translucent thin strip includes a film or non-skid coating. The strip is formed of polysiloxane. An independent claim is also included for a method for fabricating a wig.
