Reusable Hair Extension Device Using Mechanical Stud Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair extension methods are semi-permanent, time-consuming, and expensive to install and remove, and require frequent replacement due to natural hair growth, with no option for reusability or easy repositioning.
Innovation Solution
A hair extension device featuring a resilient base with upstanding headed studs and attached wefts of hair, allowing for easy attachment and removal, and enabling reusability by using a Felini grip mechanism that entwines hair strands with the studs for secure placement without adhesives or tape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesives or tape adhesives are used to attach extensions, then the extensions are securely attached to the person's naturally growing hair, but the extensions become semi-permanent and require frequent removal and replacement as hair grows out
Solution Approach 1:
The extension device is divided into separate components: a base portion with headed studs and a weft portion with hair strands. This segmentation allows the extension to be easily attached and detached as a single unit without requiring removal of adhesive bonds, thereby reducing the time and complexity of installation and removal while maintaining secure attachment through the mechanical interlocking of studs with hair loops.
2Reliability
If adhesives are used to attach extensions, then the extensions stay fixed in place, but the extensions cannot be easily repositioned or adjusted
Solution Approach 1:
The extension device employs a dynamic attachment mechanism using headed studs that can be inserted through the base and engaged with loops of natural hair. This mechanical connection can be easily adjusted by removing and reinserting the studs at different positions, allowing the extension to be repositioned or adjusted without the constraints of fixed adhesive bonding, thereby providing both secure fixation and flexibility for repositioning.
3Duration of action of stationary object
If semi-permanent extensions are installed, then the extensions provide long-lasting wear, but the extensions cannot be reused after removal
Solution Approach 1:
The extension device is designed to be reusable through its mechanical stud-and-loop attachment system. After removal from the natural hair, the base portion with headed studs can be cleaned and reused multiple times. The weft portion with hair strands can also be reused by reattaching it to a new base or repositioning it on the same base, allowing the extension to be recovered and reused rather than discarded after a single use, thereby providing both long-lasting wear and reusability.
4Reliability
If adhesive-based extensions are used, then the extensions are securely attached, but the installation and removal process is time-consuming and expensive
Solution Approach 1:
The invention replaces the chemical adhesive bonding system with a mechanical attachment system using headed studs that pass through the base and engage with loops of natural hair. This mechanical system eliminates the need for time-consuming adhesive application and drying processes, as well as the need for chemical solvents during removal. The studs can be quickly inserted and secured, and equally quickly removed by pulling the base away from the hair loops, thereby significantly reducing both installation and removal time while maintaining secure attachment.

AI summary
A two-piece hair extension device is provided having a first piece comprising a first attachment portion and a weft portion and second piece comprising an second attachment portion. The first and second attachment portions are configured to be pressed against each other with the wear's hair intertwined there between. One or more wefts of filaments are attached to the backside of at least one of the first or second attachment portions.
