Portable Hair Printer for Precise Image Dye Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair dyeing methods are inconvenient due to the need to store and mix separate containers of hair dye and oxidizing agent, leading to oxidation of the dye once mixed, and potential skin allergies from thick application.
Innovation Solution
A portable hair printer that includes a communication module, printer module, memory, and processor, allowing users to select and print images directly onto their hair, eliminating the need for mixing and reducing application time and potential skin issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hair dye and oxidizing agent are stored in separate containers and mixed when dyeing, then the dye can be reused and storage is convenient, but the mixing process is inconvenient and the dye cannot be reused after mixing
Solution Approach 1:
The patent combines hair dye and oxidizing agent into a single integrated container with separate compartments. The container includes a first storage unit for hair dye and a second storage unit for oxidizing agent, with mixing means to combine them in proper proportions. This eliminates the need to handle multiple separate containers and ensures correct mixing ratios, resolving the contradiction between storage convenience and mixing convenience.
2Reliability
If hair dye is applied thickly to ensure coverage, then dyeing effectiveness is improved, but skin allergies and side effects occur
Solution Approach 1:
The patent employs application means including a comb with teeth that have different widths, where the tip teeth are narrower than the base teeth. This creates variable application density across different regions of the hair, allowing precise control of dye application thickness. The narrower tip teeth prevent excessive application at the hair ends while broader base teeth ensure adequate coverage at the roots, eliminating the need for thick uniform application and reducing skin allergy risks.
3Reliability
If traditional hair dyeing methods are used, then complete hair coverage is achieved, but the process is time-consuming and complex
Solution Approach 1:
The patent incorporates automatic mixing means that automatically combine hair dye and oxidizing agent in the correct proportions when needed, eliminating manual mixing steps. The integrated design with separate storage units and automated mixing allows users to simply activate the device, which then handles the mixing and application process autonomously, significantly reducing the time and complexity of the dyeing process while ensuring complete hair coverage.
