Composite Wig Base Structure for Shape Retention and Skin Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wig bases made from synthetic fiber cause discomfort for users with sensitive skin due to itching, as they come into direct contact with the scalp.
Innovation Solution
A wig base design featuring a skin side layer made of natural fiber and an outer layer of synthetic fiber, bonded with an adhesive that forms a non-adhesive layer on the skin side, ensuring the scalp does not directly contact the adhesive or synthetic fiber, using natural fiber for comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a wig base is made from synthetic fiber, then the wig structure is stable and maintains shape, but it causes itching and discomfort for users with sensitive skin
Solution Approach 1:
The wig base is divided into two distinct layers: an outer synthetic fiber layer for shape stability and an inner natural fiber layer for skin comfort. This segmentation allows each layer to fulfill its specific function without compromise.
Solution Approach 2:
The wig base combines synthetic fiber and natural fiber into a composite structure. The outer layer uses synthetic fiber (acrylic, polyester, or polyamide) for structural stability, while the inner layer uses natural fiber (cotton, hemp, or silk) for skin comfort, creating a multi-material solution that resolves the contradiction between shape maintenance and skin sensitivity.
2Strength
If adhesive is used to bond the wig base layers, then the layers are securely attached, but the adhesive may cause discomfort or allergic reactions on sensitive skin
Solution Approach 1:
The adhesive is extracted from the skin-contact surface and relocated to the bonding interface between layers. This ensures that the adhesive performs its bonding function while being completely isolated from skin contact, eliminating the source of potential irritation.
Solution Approach 2:
The natural fiber inner layer acts as an intermediary barrier between the adhesive and the skin. The adhesive bonds to this intermediate layer rather than directly to the skin, preventing harmful effects while maintaining bonding strength.
3Object-affected harmful factors
If natural fiber is used for the skin side layer, then comfort for sensitive skin is improved, but the structural stability and shape maintenance may be reduced
Solution Approach 1:
The wig base is segmented into functional layers where the natural fiber inner layer provides skin comfort and the outer synthetic fiber layer provides structural stability. Each material is placed where it performs best, resolving the contradiction between comfort and stability.
Solution Approach 2:
The composite structure combines the properties of natural fiber (softness, breathability, skin compatibility) with synthetic fiber (structural integrity, shape retention). The outer synthetic layer maintains wig shape while the inner natural layer ensures skin comfort, achieving both goals simultaneously.

AI summary
A wig base is provided including a skin side layer of natural fiber, an outer layer of synthetic fiber for maintaining the shape, and adhesive for bonding the skin side layer and the outer layer together. The outer layer may be transparent fabric. The skin side layer may also be transparent fabric and the outer layer may have higher transparency than the skin side layer. The adhesive may not permeate into the skin side surface of the skin side layer. The skin side layer may be colored deep blue and pale red in comparison to the outer layer. A wig may be provided whose wig base is molded into a head shape and has hairs attached thereto. A manufacturing method for a wig base may be provided including a step of molding the wig base with a mold resembling a head through heating.
