Solution Overview
Problem
Existing hair and scalp treatment formulations, such as hair coloring systems, face challenges including difficulty of use, time consumption, uneven coverage, and unpredictable results, especially in blending new hair growth with existing dye, and are often messy and inefficient.
Innovation Solution
A reusable formulation delivery system with interchangeable cartridges containing various treatments, a formulation delivery device with a controller, and a mobile application for personalized user experience, allowing precise application and cleaning routines to ensure even distribution and minimize waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional hair coloring systems are used, then hair treatment can be applied, but the application process is messy and inefficient
Solution Approach 1:
The system divides the hair treatment application into separate components: a reusable delivery device and disposable cartridges containing the formulation. This segmentation allows precise controlled dispensing through pump mechanisms, eliminating the messiness of traditional manual application while maintaining ease of use.
Solution Approach 2:
The patent introduces an intermediary delivery device that acts as a mediator between the formulation and the user's hair. The device includes a pump system and controlled dispensing mechanism that precisely delivers the treatment, replacing direct manual application and thereby reducing messiness while improving operational ease.
2Productivity
If manual hair coloring is performed, then treatment can be applied, but it is time-consuming
Solution Approach 1:
The delivery device employs a pump system that provides continuous controlled dispensing of the formulation throughout the treatment area. This continuous action eliminates the intermittent manual application process, significantly reducing time consumption while maintaining high productivity in hair treatment application.
Solution Approach 2:
The system is designed for easy self-application by users through simple cartridge insertion and activation. The automated pump mechanism handles the complex dispensing process, allowing users to perform professional-grade treatments quickly without requiring extensive time or skill, thereby reducing time consumption while maintaining productivity.
3Manufacturing precision
If traditional formulation application is used, then treatment can be delivered, but coverage is uneven
Solution Approach 1:
The delivery device incorporates sensors and control mechanisms that monitor formulation dispensing in real-time. This feedback system ensures consistent dosage and uniform distribution across the treatment area, achieving precise coverage and reliable consistent results that manual application cannot provide.
Solution Approach 2:
The patent replaces manual mechanical application with an automated pump-based delivery system. This substitution provides precise control over formulation flow and distribution, ensuring uniform coverage and consistent results while eliminating the variability inherent in manual application methods.
4Ease of operation
If single-use cartridges are used, then formulation can be delivered, but waste is generated
Solution Approach 1:
The reusable delivery device can accept multiple different cartridge types for various hair treatments. This universality allows the same device to perform multiple functions with different formulations, reducing waste by eliminating the need for separate devices for each treatment type while maintaining ease of operation through simple cartridge swaps.
Solution Approach 2:
The system separates the reusable delivery device from the disposable cartridges. After use, only the small cartridge is discarded while the main device is recovered and reused. This approach minimizes waste by recovering and reusing the bulk of the system while still providing the convenience of disposable formulation containers.
