Selector Comb Hair Dyeing Device for Precise Lock Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for applying hair highlights are complex, prone to uneven results, and require significant skill and time, as they often lead to unwanted bleaching or dyeing of non-target hair areas due to the difficulty in precisely targeting specific locks of hair.
Innovation Solution
A device comprising a selector comb and a container with compartments for housing dye or bleach, where the comb is movable within the container, allowing for gradual introduction of hair locks into the product, ensuring precise application and minimizing unwanted dye or bleach distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If liquid dye or bleach is applied directly to hair locks, then the desired color enhancement is achieved, but the product tends to penetrate all hair including underlying hair that should not be treated
Solution Approach 1:
The device segments the hair treatment process by using a comb with teeth that physically separate and isolate individual hair locks from the surrounding hair. The comb structure creates distinct compartments where each tooth engages with a specific hair lock, preventing product transfer to adjacent hair areas.
Solution Approach 2:
The comb acts as an intermediary tool between the dye/bleach application and the hair locks. It provides a mechanical interface that selectively holds target hair locks while excluding non-target hair, enabling precise product application only to the desired areas.
2Productivity
If traditional highlight techniques are used, then hair color enhancement is achieved, but the process requires significant skill and time to obtain professional results
Solution Approach 1:
The device enables self-service operation where the comb automatically performs the selection and isolation of hair locks through its tooth structure. The user simply needs to insert the comb and apply product, without requiring manual dexterity to separate and hold individual locks, thereby reducing skill requirements and increasing speed.
Solution Approach 2:
The comb teeth preliminarily separate and organize hair locks into treatable units before product application. This pre-positioning of hair locks eliminates the need for complex manual manipulation during the dyeing process, simplifying the procedure and reducing time requirements.
3Manufacturing precision
If comb-in highlights are applied to individual locks, then fine and superficial highlights are achieved, but liquid transfers to adjacent hair that should not be dyed
Solution Approach 1:
The comb structure segments the application area by using teeth that create physical barriers between adjacent hair locks. Each tooth independently holds a specific lock, preventing liquid product from flowing to neighboring hair areas, thus eliminating unwanted product transfer.
4Manufacturing precision
If cap highlights are used with a plastic cap and crochet needle, then hair locks can be isolated for treatment, but the process is time-consuming and requires considerable skill to avoid scalp injury
Solution Approach 1:
The device extracts the essential function of hair lock isolation from the complex cap and crochet needle system. The comb directly engages with and isolates hair locks through its teeth, eliminating the need for cap placement, needle insertion, and manual lock extraction, thereby simplifying the device and process.
Solution Approach 2:
The comb automatically performs hair lock isolation and positioning through its tooth structure when inserted into the hair. This self-service mechanism eliminates the need for skilled manual manipulation required by cap and needle methods, reducing both device complexity and skill requirements.

AI summary
The present invention relates to a device and method for selectively bleaching or dyeing a plurality of locks of hair. The device basically comprises a selector comb for selecting the locks to be treated from a portion of hair, and a container provided with at least one compartment that can internally house at least one liquid or pasty product for dyeing or bleaching. The selector comb is partially introduced inside the container and is movable inside and along same, being coupled thereto such that in an operating position of the device, the movement of the comb takes place, causing the gradual introduction of an increasingly longer portion of the locks selected by the comb inside the container at the same time as the gradual opening and communication of the inside of the compartment with the portion of the locks introduced therein, said portion being exposed to the liquid or pasty product.
