Segmented Hair Dye Brush for Differential Coloring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hair dyeing methods often result in uniform coloration, which may not be ideal for individuals seeking to achieve shades or artistic designs, and lack efficiency in applying and removing dye, leading to waste and contamination.
Innovation Solution
A handheld brush with specialized brush units that carry a predicted amount of hair dye, allowing for differential coloring by applying varying shades and removing excess dye, while minimizing waste and contamination through a system of cylindrical spaces and disposable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a uniform hair dye is applied to all hairs, then the coloring process is simple and quick, but the result lacks artistic variation and does not match age-related shade changes
Solution Approach 1:
The brush is divided into multiple independent brush units (first, second, third, and fourth brush units), each capable of holding and applying different amounts of hair dye. This segmentation allows different regions of the brush to apply varying shades and amounts of dye to different hair sections, enabling artistic and age-appropriate coloring variations without requiring multiple separate brushes or complex application procedures.
2Reliability
If more hair dye is applied to ensure full coverage, then uniform coloring is achieved, but waste increases and surrounding contamination occurs
Solution Approach 1:
Each brush unit is designed with specific characteristics to hold and apply predetermined amounts of hair dye appropriate for its function. The first and second brush units hold larger amounts for main hair sections, while the third and fourth brush units hold smaller amounts for edge and detailed areas. This local optimization ensures complete coverage where needed while minimizing dye usage and preventing overflow contamination in other areas.
Solution Approach 2:
The brush design applies the principle of partial action by having different brush units apply different amounts of dye - some units apply full coverage while others apply partial coverage. This prevents excessive dye application overall while ensuring adequate coverage in areas that require it, thereby reducing waste and contamination.
3Ease of operation
If a single brush is used for all hair sections, then the device is simple to use, but precise control over dye distribution to different hair groups is difficult
Solution Approach 1:
The single brush integrates multiple independent brush units (first, second, third, and fourth brush units) that can be independently controlled. Each unit can be dipped into dye containers (fifth, sixth, seventh, or eighth containers) to load appropriate amounts of dye before application. This segmentation within a single brush provides precise control over dye distribution to different hair groups while maintaining ease of operation through a unified device.
4Productivity
If reusable brush components are used, then environmental impact is reduced, but cleaning and hygiene maintenance becomes complex
Solution Approach 1:
The invention employs disposable brush units and dye containers that are discarded after use. This eliminates the need for complex cleaning and hygiene maintenance of reusable components while minimizing environmental impact through controlled disposal of small, contained units. The disposable nature ensures hygiene without requiring elaborate cleaning procedures.
Solution Approach 2:
The system is designed to discard used brush units and dye containers after a single use, preventing cross-contamination and eliminating cleaning requirements. The modular disposable design allows for efficient disposal while minimizing waste through precise dye application that reduces excess material needing disposal.

AI summary
Coloring of hairs are commonly done for various reasons. Commonly, a single hair dye is applied which leaves a uniform coloring of the hairs. However, many prefer having shades of hair coloring or two different coloring. Thus in this application methods and means are introduced that allows a differential coloring to be possible. In this method a hand held brush means allows a predicted amount of the hair dye to be carried to the hairs and applied. Also a special dye pan allows a predicted amount of hair dye to be applied to the brush units to make such goals possible.
