Solution Overview

Problem

Conventional hair extensions are costly, inconvenient to install, and prone to premature slippage or falling out due to temporary attachment methods like clips or glue, which do not provide a secure and long-lasting solution for enhancing natural hair volume and length.

Innovation Solution

A hair extension device featuring a cord member in a loop with artificial hair strands that can be securely attached using various methods such as crocheting, gluing, or sewing, and incorporating fasteners like rubber bands or wires, along with mesh members and drawstrings for adjustable and tight securing to the user's natural hair.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If clips or glue are used to attach hair extensions, then installation is simple and low cost, but the extensions slip or fall out over time

Engineering Contradiction:
Improveinstallation simplicityVSAvoidattachment security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The hair extension device is divided into separate functional components: a cord member configured in a loop and an artificial hair extension member that can be independently attached. This segmentation allows the cord to provide secure anchoring while the hair extensions can be easily attached and removed, resolving the contradiction between simple installation and secure attachment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cord member acts as an intermediary between the user's natural hair and the artificial hair extensions. It provides a secure anchor point that prevents slippage while allowing for easy attachment and removal of the extensions, thus maintaining both reliability and ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If professional expertise is required to install high-end hair extensions, then appearance quality is improved, but cost and inconvenience increase

Engineering Contradiction:
Improveappearance qualityVSAvoidinstallation convenience
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The hair extension device is designed to be self-installable by ordinary consumers without requiring professional expertise. The simple loop configuration of the cord member and the straightforward attachment method enable users to achieve high-quality appearance results independently, eliminating the need for costly professional installation while maintaining appearance quality.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If temporary attachment methods are used, then installation is easy and low cost, but the extensions are only temporarily effective

Engineering Contradiction:
Improveinstallation easeVSAvoidattachment duration
Core Design Contradiction:
Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The cord member is designed with dynamic characteristics, configured in a loop that can be easily adjusted and repositioned. This dynamic design allows the attachment to remain secure over time while still enabling easy removal and reinstallation, thus extending the effective duration without sacrificing installation ease.

Inventive Principle:
Principle #15Dynamics
