Wig Hair Structure Alternating Curl Diameters for Volume Stability

Solution Overview

Problem

Wigs with hairs of mixed curl diameters struggle to maintain a voluminous appearance due to insufficient support from smaller curl diameter hairs, leading to falling over under external forces, while larger curl diameters fail to achieve the desired voluminous feeling.

Innovation Solution

A wig design featuring alternate regions with hairs of different curl diameters, where hairs with a larger curl diameter are supported by those with a smaller curl diameter, ensuring stability and maintaining the voluminous appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If hairs with larger curl diameter are used, then voluminous feeling is enhanced, but hairs easily fall over due to small external force

Engineering Contradiction:

Improvevoluminous feelingVSAvoidhair stability

Core Design Contradiction:

Volume of moving objectVSStability of the object's composition

Solution Approach 1:

The patent applies local quality by creating distinct regions with different hair curl diameters within the wig. Specifically, it defines a first region with hairs of a first curl diameter and a second region with hairs of a second curl diameter, where the ratio of their lengths is between 0.5 and 2.0. This allows different parts of the wig to have different properties: the first region provides voluminous feeling while the second region provides stability, resolving the contradiction between volume and stability.

Inventive Principle:

Principle #3Local quality

2Stability of the object's composition

If hairs with smaller curl diameter are used, then hairs are prevented from falling over, but voluminous feeling is reduced

Engineering Contradiction:

Improvehair stabilityVSAvoidvoluminous feeling

Core Design Contradiction:

Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The patent applies local quality by creating distinct regions with different hair curl diameters within the wig. Specifically, it defines a first region with hairs of a first curl diameter and a second region with hairs of a second curl diameter, where the ratio of their lengths is between 0.5 and 2.0. This allows different parts of the wig to have different properties: the first region provides voluminous feeling while the second region provides stability, resolving the contradiction between volume and stability.

Inventive Principle:

Principle #3Local quality

3Volume of moving object

If hairs with different curl diameters are mixed at predetermined rate, then voluminous feeling is improved, but support from smaller curl diameter hairs is insufficient

Engineering Contradiction:

Improvevoluminous feelingVSAvoidsupport reliability

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The patent applies segmentation by dividing the wig into distinct regions (first region and second region) with different hair characteristics. Instead of randomly mixing hairs of different curl diameters throughout the wig, it creates structured zones where hairs of specific curl diameters are placed in specific regions. This segmentation ensures that hairs with smaller curl diameters are positioned to provide reliable support to hairs with larger curl diameters, improving support reliability while maintaining voluminous feeling.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by creating distinct regions with different hair curl diameters within the wig. Specifically, it defines a first region with hairs of a first curl diameter and a second region with hairs of a second curl diameter, where the ratio of their lengths is between 0.5 and 2.0. This allows different parts of the wig to have different properties: the first region provides voluminous feeling while the second region provides stability, resolving the contradiction between volume and stability.

AI summary

An object of the present invention is to surely provide a wig with hairs that ensures the desired voluminous feeling. A wig comprises an alternate arrangement, the alternate arrangement including: a first region of a wig base in which a plurality of first hairs having a first curl diameter are implanted, the first hair being an artificial hair or a natural hair; and a second region of the wig base in which a plurality of second hairs having a second curl diameter smaller than the first curl diameter are implanted, the second hair being an artificial hair or a natural hair, the first and second regions being adjacent to each other and alternately arranged.
