Dispensing Head with Foam Pad and Comb Teeth for Hair Products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair product application methods are cumbersome, requiring multiple steps and tools, leading to inefficient and non-homogeneous application, especially for hair products like dyes and care products, which often result in product loss and limited coverage.
Innovation Solution
A dispensing and application head with a foam pad applicator and surrounding comb teeth that allows for simultaneous dispensing, application, and combing, ensuring even distribution and retention of the product, while minimizing product loss and tangling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate comb and foam applicator are used as in prior art, then combing function is provided, but multiple gesture movements are required and convenience is reduced
Solution Approach 1:
The patent combines the foam applicator and comb into a single integrated head assembly. The foam applicator is positioned within the comb structure, allowing both functions to be performed simultaneously in one application motion, eliminating the need for separate combing and application steps required by prior art devices
2Reliability
If brush applicator is used as in GB2243766, then product dispensing is achieved, but contact with hair is limited and application is not optimum
Solution Approach 1:
The patent uses a foam applicator instead of a brush applicator. The foam material provides superior contact with the hair surface due to its porous structure, allowing for better product distribution and penetration. The foam can conform to the hair texture and provide uniform application across the entire treated area, unlike the limited contact of brush bristles
3Productivity
If multiple separate tools are used for dispensing and application, then product can be applied, but application is troublesome and requires multiple steps
Solution Approach 1:
The patent integrates the dispensing mechanism, foam applicator, and comb into a single unified device. This allows the user to perform dispensing, application, and combing in one continuous motion, significantly reducing the time and effort required compared to using separate tools for each function
Solution Approach 2:
The integrated head assembly performs multiple functions simultaneously: it dispenses the cosmetic product through the foam applicator while the comb teeth detangle and distribute the product through the hair. This multi-functionality eliminates the need for separate combing and application steps, improving both speed and simplicity
4Manufacturing precision
If hand application is used, then product can be applied to hands, but homogeneous application and even spreading are not ensured
Solution Approach 1:
The foam applicator's porous structure allows for uniform product distribution across its surface. When applied to the hair, the foam conforms to the hair texture and provides even spreading, eliminating the uneven application that occurs with manual hand application. The foam material naturally distributes the product uniformly through its cellular structure
