Triangular Hair Foil Creasing Device for Faster Color Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rectangular hair foils require multiple folds for preparation, making the hair coloring process time-consuming and prone to uneven product saturation and product displacement, with machines being expensive and not universally available.
Innovation Solution
A small brake device for manually creasing triangular hair foils, allowing for a single fold to lock the foil packet in place, which facilitates quicker and cleaner application, reducing the risk of product displacement and providing better coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rectangular hair foils are used, then they can be prepared with multiple folds to lock the foil packet, but the preparation process becomes time-consuming and tedious
Solution Approach 1:
The invention divides the rectangular foil into two triangular halves by creating a crease down the center. This segmentation allows each triangular half to fold independently and lock securely onto the hair section, eliminating the need for multiple folds required by conventional rectangular foils. The triangular shape enables the foil to be folded once and locked in place, significantly reducing preparation time while maintaining reliable packet locking.
2Reliability
If multiple folds are used to lock rectangular foils, then the foil packet can be secured, but product displacement and uneven saturation occur
Solution Approach 1:
By segmenting the rectangular foil into two triangular halves, the invention creates a more precise fit around the hair section. Each triangular half can be folded and locked to secure the packet without creating excessive pressure that causes product displacement. The triangular geometry allows for better distribution of the coloring product across the hair section, ensuring uniform saturation while maintaining secure packet locking.
3Productivity
If conventional rectangular foils are used, then they can be prepared and used, but machines for automated preparation are expensive and not universally available
Solution Approach 1:
Instead of investing in expensive automated machines to improve productivity, the invention inverts the approach by simplifying the manual preparation process through geometric design. The triangular foil shape enables manual folding and locking that is faster and cleaner than conventional rectangular foil preparation, achieving high productivity through a simple, low-cost manual technique rather than through expensive automation equipment.
4Productivity
If triangular foils are used with single fold, then application is quicker and cleaner, but the device for creasing must be simple and economical
Solution Approach 1:
The invention employs a self-service approach where the triangular foil shape itself facilitates the creasing process. The foil's geometry allows it to be easily folded and creased using simple manual techniques or basic tools already available in hair salons. The triangular shape naturally guides the folding action, eliminating the need for complex specialized creasing devices while maintaining quick and clean application.

AI summary
A hair folding and creasing brake device for creating pre-folded and creased triangular hair foils for dimensional hair color placement has a hinged sheet which is hinged so that foil sheets placed on its surface can be clamped and then bent to form a crease in the foil. A hair coloring foil is prepared by placing a foil or a pack of foils onto the device which is then folded over the foil to clamp the foil and then then folded again to bend the foil to impart a crease to the foil.
