Hairbrush Applicator Flow Control for Targeted Dry Shampoo
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing haircare products, such as dry shampoo applicators, often result in excessive application, waste, and unwanted spray dispersion, and fail to provide targeted and even distribution without using brushes or combs, while also posing issues like scalp itchiness and clogged pores.
Innovation Solution
A hairbrush applicator configuration with a bristle assembly, base tray, and a rotating collar that controls material flow through adjustable flow holes and channels, allowing for targeted application and even distribution of dry shampoo or powder without aerosol sprays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If aerosol sprays are used to apply dry shampoo, then application speed is improved, but product waste and unwanted dispersion increase
Solution Approach 1:
The applicator divides the product delivery system into separate functional components: a storage container for product, a dispensing mechanism with flow control holes, and a bristle assembly for application. This segmentation allows precise control over product flow to the bristles, preventing waste while maintaining efficient application.
Solution Approach 2:
The bristle assembly serves as an intermediary between the stored product and the hair. Product flows through controlled holes in the applicator base to the bristles, which then distribute it evenly through the hair shafts. This intermediary mechanism prevents direct spray dispersion onto the face and clothes while maintaining controlled application.
2Productivity
If aerosol sprays are used to apply dry shampoo, then application speed is improved, but unwanted material dispersion onto face and clothes increases
Solution Approach 1:
The bristle assembly acts as an intermediary that channels product directly onto the hair shafts rather than allowing uncontrolled spray dispersion. The structured bristle arrangement ensures product is deposited only where needed, preventing harmful dispersion onto the face and surrounding areas.
Solution Approach 2:
The patent replaces the aerosol spray mechanism with a mechanical dispensing system using controlled flow holes and a bristle-based application method. This substitution eliminates the harmful dispersion characteristics of aerosols while maintaining the speed of application through the engineered flow control and bristle distribution system.
3Ease of operation
If powder is applied without a brush or comb, then application simplicity is improved, but even distribution is compromised
Solution Approach 1:
The invention merges the dispensing function and the distribution function into a single integrated bristle assembly. The bristles are positioned and angled to simultaneously receive product from the flow holes and distribute it evenly through the hair, combining what would traditionally be separate steps into one unified action.
Solution Approach 2:
The bristle assembly provides local quality by positioning individual bristles at specific angles and orientations to target different sections of the hair. This localized arrangement ensures even distribution across the entire hair surface while maintaining operational simplicity through the unified applicator design.
4Quantity of substance
If powder contacts the scalp, then application coverage is improved, but scalp health issues increase
Solution Approach 1:
The bristle assembly is designed with specific local quality characteristics - bristles are angled and positioned to target the hair shafts rather than the scalp. This localized application approach ensures comprehensive hair coverage while deliberately avoiding scalp contact, preventing issues like itchiness and clogged pores.
Solution Approach 2:
The bristle assembly serves as an intermediary that delivers product to the hair shafts without direct scalp contact. The bristles act as a mediating structure that channels product along the hair shafts, providing coverage while protecting the scalp from harmful powder contact.
