Dual-Container Hair Dye Applicator for Waste Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional hair dye application methods are messy, wasteful, and inconvenient, especially for small or touch-up applications, as they require separate containers for color and developer, leading to oxidation and loss of unused dye, and often necessitate repeated purchases and salon visits.
Innovation Solution
A hair dye applicator comprising two interconnected containers, one for the color component and one for the developer, allowing for self-contained mixing and easy application, with a mechanism to store unused dye without decomposition, reducing waste and the need for frequent purchases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional separate containers for color and developer are used, then storage stability is improved, but convenience and ease of application deteriorate
Solution Approach 1:
The patent combines two separate containers (color and developer) into a single integrated applicator device with an internal mixing chamber. This merging allows the dye components to be stored separately for stability while enabling easy mixing and application through a unified device, resolving the contradiction between storage stability and ease of operation.
Solution Approach 2:
The applicator device serves multiple functions: it stores color and developer separately, mixes them automatically, and applies the dye to hair. This multi-functionality eliminates the need for separate containers and manual mixing, improving convenience while maintaining the stability benefits of separate storage.
2Reliability
If traditional hair dye application methods are used, then dye efficacy is maintained, but waste and loss of substance increase
Solution Approach 1:
The applicator automatically mixes the color and developer in precise proportions and applies only the required amount to the hair. This self-service mechanism prevents over-pouring and oxidation of unused dye, maintaining efficacy while minimizing waste compared to manual application methods.
Solution Approach 2:
The device allows recovery of unused dye by storing it in the applicator's reservoir for later use, eliminating the need to discard remaining dye after a single application. This recovers valuable substance and maintains efficacy for subsequent applications.
3Device complexity
If traditional separate container method is used, then component storage is simplified, but device complexity and inconvenience increase
Solution Approach 1:
The patent merges storage and application functions into a single device, eliminating the need for separate containers and manual mixing steps. This integration simplifies the overall system while improving ease of operation, as users simply attach the applicator to their existing container and press a button to mix and apply.
