Highlight Applicator Lever Mechanism Frictional Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hair dye and highlighting applicators are labor-intensive, expensive, and often result in inconsistent or unnatural hair color effects, especially for home users, due to the difficulty in precisely applying hair products to specific sections of hair without assistance, leading to unwanted color bleeding and uneven results.
Innovation Solution
A highlight applicator with a flexible bristle member and lever mechanism that creates a frictional seal, allowing for adjustable bristle configurations to grasp and evenly apply hair coloring compositions to multiple strands of hair, providing precise control over the application width and minimizing color bleeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If home dye treatments are used to avoid salon expenses, then cost is reduced, but application precision and natural appearance deteriorate
Solution Approach 1:
The applicator device enables self-service application with professional results. The device includes a holder that secures the hair strand and a applicator tip that precisely delivers color to the target area, allowing consumers to achieve salon-quality highlighting at home without requiring professional assistance or expensive salon visits.
Solution Approach 2:
The device allows adjustment of application parameters including the width of the applicator tip and the position of the applicator along the hair strand. This enables precise control over the highlighted area width and location, transforming the application process from imprecise to highly controllable for home users.
2Ease of operation
If home highlighting kits are used without foils, then ease of use is improved, but color bleeding and unnatural effects increase
Solution Approach 1:
The applicator device acts as an intermediary between the hair color product and the hair strand. It includes a holder that physically separates and secures the targeted hair strand, preventing color from bleeding to adjacent strands. This mediator function eliminates the need for separate foil barriers while preventing color bleeding.
Solution Approach 2:
The applicator utilizes a flexible applicator tip and holder structure that can conform to the hair strand shape. This flexible design allows precise application while the holder structure maintains physical separation to prevent color bleeding, combining flexibility with protective function.
3Manufacturing precision
If manual strand separation is required for precise highlighting, then application precision is improved, but operation complexity and time increase
Solution Approach 1:
The applicator device segments the hair strand handling function into a dedicated holder component that secures the targeted strand. This segmentation allows the user to focus only on placing the device on the target area, while the holder automatically maintains strand separation and positioning, reducing the complexity of manual separation tasks.
Solution Approach 2:
The device replaces complex manual strand separation and positioning mechanics with a mechanical holder system. The holder automatically grasps and secures the hair strand, eliminating the need for consumers to manually separate and position multiple strands with precision tools, thereby reducing operational complexity.
4Ease of operation
If fixed width applicators are used, then ease of operation is improved, but adaptability to different hair widths decreases
Solution Approach 1:
The applicator features an adjustable width mechanism that allows the applicator tip opening to be dynamically changed. This enables the device to adapt to different hair strand widths and highlighting requirements, transforming a static applicator into a dynamic, versatile tool that maintains ease of use while providing customization capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to achieve professional-quality, multi-tonal hair effects with greater ease and precision, reducing the risk of color bleeding and ensuring consistent application, thus enhancing the overall appearance of hair color without the need for extensive salon training or equipment.
Implementation Method 1
A lever (102) is coupled with the flexible bristle member (110) and is configured to manipulate the bristles (114) of the flexible bristle member (110). The bristles (114) are configured to create a frictional seal between an exterior circumference of the flexible bristle member (110) and an interior circumference of the body (104).

AI summary
A hair applicator comprises a body, a flexible member, and a means of transferring a center of the flexible member. The flexible member comprises bristles, which may be arranged in a circular pattern and/or of differing lengths. A user applies an appropriate amount of hair coloring composition within the bristles of the flexible member. When the center of the flexible member is moved, the shape of the flexible member is changed which causes the bristles to form a conical shape which may be used to grasp strands of hair. The user combs the hair coloring composition throughout the length of the hair to effectively highlight the desired hair strands.
