Solution Overview

Problem

Existing wigs directly bonded to the scalp cause skin irritation and injury due to adhesive contact, leading to discomfort and scalp damage.

Innovation Solution

A wig-fixing strap with a base body part that encircles the head and a connecting part that secures the wig, eliminating the need for adhesive by providing stability through encircling and securing mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If wig adhesive is used to bond wig directly to scalp, then wig fixation strength is improved, but skin irritation and scalp injury occur

Engineering Contradiction:

Improvewig fixation strengthVSAvoidskin irritation and scalp injury

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a fixing strap as an intermediary device between the wig and the scalp. The strap encircles the head and provides mechanical fixation through buckles and fastening mechanisms, eliminating the need for adhesive substances that cause skin irritation. This mediator approach allows strong fixation without direct chemical contact between the wig and scalp.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention replaces the chemical bonding system (adhesive) with a mechanical fixation system. The fixing strap uses buckles, fastening mechanisms, and elastic structures to provide mechanical attachment of the wig to the head, substituting the need for chemical adhesives that cause harmful skin reactions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If wig is encircled with fixing strap, then scalp health is improved by eliminating adhesive, but wig fixation stability must be maintained

Engineering Contradiction:

Improvescalp healthVSAvoidwig fixation stability

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The fixing strap incorporates elastic structures and flexible materials that can conform to the contours of the head while providing secure fixation. The elastic components allow the strap to maintain constant fixation force without being too tight or too loose, ensuring both scalp comfort and wig stability.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The fixing strap design includes adjustable fastening mechanisms and elastic components that can dynamically adapt to different head sizes and shapes. The buckles and fastening systems allow for adjustment to achieve optimal fixation strength while maintaining scalp health, providing a dynamic solution rather than a fixed rigid structure.

Inventive Principle:

Principle #15Dynamics

AI summary

The present invention provides a wig-fixing strap and a wig piece. The wig-fixing strap includes a base body part used to encircle a user's head; and a connecting part set on the base body part, which is used to fit and connect with and a wig. The above arrangement enables the wig to hold on the user's scalp and to be fixed with the peripheral base body part, thereby greatly improving wearing stability of the wig, without additional adhesive between the wig and the user's scalp, lessening the impact on the user's scalp and helping to ameliorate the health of the user's scalp.
