Hairbrush Applicator With Rotating Collar for Dry Shampoo Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing haircare products, such as dry shampoo applicators, often result in excessive application, waste, and unwanted spray byproducts, and there is a need for targeted, waste-reducing, travel-friendly applicators that do not use flammable liquids.
Innovation Solution
A hairbrush applicator configuration with a bristle assembly, base tray, and a rotating collar that controls material flow through adjustable flow holes, allowing for targeted application and even distribution of products like dry shampoo without aerosols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If aerosol sprays are used to apply dry shampoo, then product application is convenient, but excessive product is applied causing waste and unwanted spray byproducts
Solution Approach 1:
The applicator divides the product delivery system into separate functional components: a storage container for product, a dispensing mechanism with controlled openings, and a bristle assembly for application. This segmentation allows precise control over product flow to the bristles, preventing excessive application while maintaining ease of use.
Solution Approach 2:
The bristle assembly serves as an intermediary between the stored product and the hair. Product flows from the container through controlled openings to the bristles, which then distribute it evenly through the hair. This intermediary mechanism prevents direct spray contact with the scalp and reduces waste by controlling the exact amount of product applied.
2Productivity
If aerosol sprays are used for product application, then quick application is achieved, but harmful byproducts are generated and scalp contact causes itchiness and clogged pores
Solution Approach 1:
The harmful aerosol spray mechanism is completely removed from the system. Instead, a solid bristle assembly with controlled product openings is used. This extraction of the harmful element eliminates spray byproducts and direct scalp contact while maintaining application speed through the bristle's natural distribution capability.
Solution Approach 2:
The applicator uses a disposable bristle assembly that can be easily replaced. This eliminates the need for complex, reusable aerosol systems and their associated harmful byproducts. The simple, replaceable bristle assembly provides a clean, safe application method without the harmful effects of aerosols.
3Quantity of substance
If traditional dry shampoo applicators are used, then product can be applied, but proper application control is not achieved resulting in too much product
Solution Approach 1:
The applicator incorporates a rotatable collar with multiple positions that dynamically adjusts the alignment between product openings and bristle channels. This dynamic adjustment mechanism allows precise control over the amount of product reaching the bristles, enabling users to optimize application quantity for different hair types and needs.
Solution Approach 2:
The system changes the parameter of product flow control by using a rotatable collar with multiple angular positions. Each position corresponds to a different alignment between product openings and bristle channels, allowing precise modulation of product quantity. This parameter change mechanism provides fine-grained control over application amount.
4Manufacturing precision
If a hairbrush applicator with rotating collar is used, then controlled material flow is achieved, but device complexity increases
Solution Approach 1:
The applicator merges multiple functions into integrated components: the collar combines rotation control with positioning, the bristle assembly combines product reception with hair application, and the handle integrates storage with the dispensing mechanism. This merging reduces the number of separate parts while maintaining precise control over material flow.
Solution Approach 2:
The handle serves multiple functions: it provides structural support, contains the product storage container, houses the rotatable collar mechanism, and acts as the application tool. This multi-functionality reduces overall device complexity by eliminating the need for separate components for each function.
