Rotating Hook Applicator for Controlled Hair Color Variegation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair color variegation methods in salons are time-consuming, inconsistent, lack control over color application, and struggle with color bleeding, especially when using high viscosity colorants, and do not effectively address the need for quick, safe, and accurate application of color to selected hair sections.
Innovation Solution
A hand-held device with a hooking applicator mechanism that pivots to entrain hair sections against a color applicator nozzle, allowing for controlled application of both low and high viscosity colorants, with features like a saturation chamber and adjustable hooks for precise hair selection and color deposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the foil method is used for hair color variegation, then color bleeding is reduced and variegated appearance is improved, but the process becomes very time consuming and expensive
Solution Approach 1:
The invention extracts the essential function of the foil method (preventing color bleeding) while eliminating its time-consuming aspects. The barrier element is integrated directly into the applicator tool, allowing color application without requiring separate foil placement and removal steps, thus reducing processing time while maintaining color containment effectiveness
Solution Approach 2:
The invention merges the barrier element with the applicator tool into a single integrated unit. The barrier element is positioned between the color applicator and the hair, combining the functions of color application and color containment in one tool, which eliminates the need for separate foil handling steps and reduces overall processing time
2Measurement precision
If manual weaving and foil placement is used for hair color variegation, then precise hair section selection is achieved, but the procedure becomes complex and time consuming
Solution Approach 1:
The applicator tool is divided into distinct functional segments: a hair engagement element for precise section selection, a barrier element for color containment, and a color applicator element. This segmentation allows each component to perform its specific function independently, maintaining precision in hair section selection while simplifying the overall procedure
Solution Approach 2:
The integrated applicator tool performs multiple functions simultaneously: it selects hair sections, contains color, and applies color. This multi-functionality eliminates the need for separate tools and steps, reducing procedure complexity while maintaining the precision achieved through manual weaving
3Quantity of substance
If high viscosity colorants are used, then color coverage is improved, but application control becomes difficult and color bleeding increases
Solution Approach 1:
The barrier element serves as an intermediary between the high viscosity colorant and the hair. It contains the thick colorant during application, preventing it from spreading to adjacent areas, and then releases it for controlled deposition on the selected hair section, thus maintaining both color coverage and application control
Solution Approach 2:
The barrier element creates a localized containment zone around the color application point. This local quality allows the high viscosity colorant to be applied with full coverage potential while preventing unwanted spreading, as the barrier element provides localized control rather than global containment
