Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wig foundations lack sufficient stability and comfort, particularly for wigs that rely on combs or hair clips for support, as they do not provide a tight and secure fit around the head, leading to potential slippage or removal by wind.

Innovation Solution

A wig foundation with a stitched support hem featuring an inverted bowl-shaped stretchable cap, a pocketed band with reinforcement stitching, and elasticized straps that encircle the head, providing enhanced support and tightness through a continuous 360° circumference attachment and adjustable tightening mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing wig foundations are used, then the structure is simple, but the stability and security of the wig on the head is insufficient

Engineering Contradiction:

Improvestability of wig fitVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The wig foundation is divided into multiple functional segments: an inverted bowl-shaped cap for head coverage, a pocketed band for attachment, reinforcement stitching for structural support, and elasticized straps for securing. Each segment performs a specific function that contributes to overall stability, resolving the contradiction by making the structure complex only where necessary for reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The reinforcement stitching is pre-applied to the pocketed band to create a strengthened attachment area before the wig is installed. This preliminary reinforcement ensures that when combs or hair clips are attached, they have a stable foundation, improving reliability without adding complexity during the wearing process.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If a tighter fit is achieved through additional support structures, then the wig stability improves, but the comfort and breathability may deteriorate

Engineering Contradiction:

Improvesecurity of wig fitVSAvoidcomfort and breathability

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The inverted bowl-shaped cap is made from a flexible, breathable material that conform to the head shape while allowing air circulation. This flexible structure provides the necessary tightness and security without creating rigid constraints that would compromise comfort or breathability.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The cap material incorporates porous properties that allow air to pass through, maintaining breathability even when the cap is fitted tightly to the head. This resolves the contradiction by enabling a secure fit while preventing suffocation or discomfort from poor air circulation.

Inventive Principle:

Principle #31Porous materials

3Ease of manufacture

If combs or hair clips are used for wig support, then the attachment method is simple, but the wig may slip or be removed by wind

Engineering Contradiction:

Improvesimplicity of attachmentVSAvoidresistance to slippage

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The pocketed band with reinforcement stitching is pre-constructed to provide a strengthened attachment foundation. Combs and hair clips are then attached to this reinforced area, which maintains the simplicity of using these common attachment methods while significantly improving their ability to resist slippage and wind.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The attachment system combines multiple materials and methods: the pocketed band fabric, reinforcement stitching threads, combs, and hair clips work together as a composite system. This combination provides both the simplicity of mechanical attachment and the reliability needed to prevent slippage, as each component compensates for the limitations of the others.

Inventive Principle:

Principle #40Composite materials

AI summary

A wig foundation with a stitched support hem including an inverted bowl-shaped stretchable cap having a center portion and a pair of semicircular side panels. A pocketed band is attached to a bottom edge of the cap. A pair of openings of the pocketed band are medially disposed between a back end of each of a right seam and a left seam of a pair of seams. A single elasticized strap is threaded through both the pocketed band and a right opening and a left opening of the pair of openings so that a first end and a second end of the single elasticized strap are disposed outside of the cap. A tightening mechanism is attached to the single elasticized strap proximal the first and second ends thereof, and is configured to selectively tighten the cap around a head of a wearer by selectively tightening the single elasticized strap.
