Solution Overview

Problem

Current hair color variegation techniques lack precision, consistency, and speed, often resulting in unpredictable and undesirable outcomes due to difficulties in selectively applying color to specific hair sections without bleeding onto adjacent areas, and require significant manual effort and time.

Innovation Solution

A hand-held device with a hooking applicator that pivots to entrain hair sections against color nozzles, allowing for controlled application of both low and high viscosity hair color, with a mechanism to mix colors just before application and a design that conforms to the scalp for accurate and efficient color deposition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If a cap with holes is used to apply hair color, then color bleeding is reduced, but the precision of selecting specific hair sections deteriorates

Engineering Contradiction:
Improvecolor bleedingVSAvoidprecision of selecting hair sections
Core Design Contradiction:
Object-generated harmful factorsVSManufacturing precision

Solution Approach 1:

The device divides the hair treatment process into distinct functional segments: the hooking applicator segments to selectively capture specific hair sections, while the color applicator segments deliver color precisely to those captured sections. This segmentation allows independent optimization of each function, achieving both precise section selection and prevented color bleeding.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hooking applicator acts as an intermediary mechanism between the operator and the hair sections. It mechanically captures and isolates the desired hair sections before color application, serving as a mediator that ensures precise selection while preventing color from reaching unintended areas.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If manual combing methods are used to apply hair color, then equipment complexity is reduced, but the speed and productivity of the process deteriorates

Engineering Contradiction:
Improveequipment simplicityVSAvoidspeed of hair coloring
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The device merges multiple functions into a single integrated tool: hair section selection, isolation, and color application are all performed by one device rather than requiring separate combs, foils, and brushes. This consolidation maintains operational simplicity while dramatically increasing processing speed and productivity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The device is designed with multi-functionality, where the same device performs both the selection/isolation of hair sections and the application of color. The hooking applicators and color applicators work together in a single operational cycle, making the device universal for both sectioning and coloring tasks.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Manufacturing precision

If the foil method is used for hair variegation, then precision of hair section selection is improved, but the time required for the process increases

Engineering Contradiction:
Improveprecision of hair section selectionVSAvoidtime required for coloring process
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The hooking applicators perform preliminary action by pre-capturing and isolating the desired hair sections in a single mechanical motion before color application begins. This preliminary sectioning eliminates the time-consuming steps of manual foil placement and section management, allowing immediate color application to precisely selected sections.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The device enables continuous useful action by maintaining the hair sections in a captured state throughout the entire color application process. The sections remain isolated and accessible without interruption, allowing uninterrupted color deposition and eliminating the time losses associated with repeated positioning and adjustment required by foil methods.

Inventive Principle:
Principle #20Continuity of useful action
