Thread Ring Hair Extension Knotting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pre-bonded hair extensions using hot-melt glue pose risks of scalp and skin damage, burning hazards, and require expensive equipment, along with inefficient and time-consuming application processes.
Innovation Solution
A hair extension method utilizing a thread with a ring portion that forms two knots to securely attach and detach hair extensions without glue or expensive equipment, using a thread that is intertwined with the hair to prevent falling and easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-bonded hair extension using hot-melt glue is used, then hair extension can be attached, but scalp and skin damage occurs due to glue exposure
Solution Approach 1:
The patent removes the harmful glue component from the hair extension system entirely, replacing it with a mechanical knotting mechanism using thread. This extraction of the harmful substance (glue) eliminates scalp and skin damage while maintaining attachment functionality through the ring portion and knotting system.
Solution Approach 2:
The patent introduces a thread with ring portion as an intermediary mechanical fastening system between the hair extension and natural hair. This intermediary replaces the chemical bonding of glue with physical knotting, providing secure attachment without chemical exposure to the scalp.
2Ease of manufacture
If hot iron heated above 150 degrees Celsius is used for pre-bonded hair extension, then glue can be melted for attachment, but burning hazard occurs to the user
Solution Approach 1:
The patent replaces the thermal field (hot iron heating) with a mechanical field (hand-tied knotting). Instead of using heat to melt and apply glue, the system uses manual mechanical actions to tie the thread and form knots, eliminating burning hazards while achieving secure attachment.
Solution Approach 2:
The patent uses a simple, inexpensive thread-based system that can be easily applied and removed without expensive equipment. The thread and ring portion constitute a disposable or reusable mechanical fastening system that eliminates the need for costly hot iron apparatus.
3Ease of manufacture
If expensive hot iron apparatus is used for pre-bonded hair extension, then glue can be melted and applied, but high equipment cost is incurred
Solution Approach 1:
The patent replaces expensive, complex hot iron apparatus with simple, inexpensive thread and ring portion components. The mechanical knotting system requires no powered equipment, making the procedure accessible without investment in costly machinery while achieving the same attachment goal.
Solution Approach 2:
The patent extracts and removes the expensive hot iron equipment from the hair extension process entirely, replacing it with a manual, equipment-free knotting system. This elimination of complex thermal processing equipment dramatically reduces costs while maintaining attachment effectiveness.
4Ease of repair
If alcohol or acetone-based remover is used for pre-bonded hair extension removal, then glue can be dissolved, but skin troubles such as allergy occur
Solution Approach 1:
The patent removes the need for chemical removers (alcohol, acetone) by using a mechanical knotting system instead of chemical bonding. The thread can be simply cut and untied without requiring solvents, eliminating skin irritation and allergic reactions associated with chemical exposure during removal.
Solution Approach 2:
The mechanical thread and knot system serves as an intermediary that allows easy physical separation without chemical intervention. The attachment can be removed by cutting and untying the thread, providing a safe, chemical-free removal process that protects skin health.
5Reliability
If pre-bonded hair extension process is used, then hair extension can be attached, but it takes 4-5 hours due to inefficiency of melting glue and rotating hands
Solution Approach 1:
The patent replaces the time-consuming thermal process of melting and applying glue with a quick mechanical knotting process. The ring portion and thread can be rapidly tied and secured by hand without waiting for heating or cooling cycles, dramatically reducing application time from 4-5 hours to a fraction of that time.
Solution Approach 2:
The ring portion is pre-formed on the thread before application, allowing the practitioner to simply thread and knot the system during application. This preliminary preparation of the fastening mechanism eliminates time-consuming steps of heating, melting, and precise glue application, streamlining the entire process.
6Object-affected harmful factors
If ultrasonic device is used for hair extension, then burning hazard is reduced, but the device is expensive and easily broken
Solution Approach 1:
The patent replaces expensive, fragile ultrasonic devices with simple, durable thread and ring portion components that require no powered machinery. The mechanical knotting system is inexpensive, robust, and eliminates all thermal and ultrasonic energy sources, providing a safe and economically viable alternative.
Solution Approach 2:
The patent extracts and removes the ultrasonic device from the hair extension process entirely, replacing it with a purely mechanical hand-tied system. This elimination of complex electronic and ultrasonic equipment reduces costs, increases durability, and maintains safety by avoiding all forms of energy-based processing.
7Reliability
If tube hair extension method with metal tube is used, then hair extension can be attached, but hairs can be damaged or cut away when pressing
Solution Approach 1:
The patent uses a flexible thread and ring portion system instead of rigid metal tubes for attachment. The soft, flexible thread conforms to the hair and scalp without exerting concentrated pressure that could damage or cut the hair, while still providing secure mechanical fastening through knotting.

AI summary
A hair extension for attachment to a hair is provided. The hair extension comprises an extending hair portion and a thread connected to the extending hair portion and configured to be tied to a hair to create an attachment. A ring portion is formed between both ends of the thread for inserting the hair, tightening, and fixing to the inserted hair. Expensive equipment is not required for attaching and removing the hair extension.
