Make-up Applicator Dispenser Valve Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional make-up items with wipers lead to excessive product loading, uneven application, product drying, and wastage due to geometrical constraints and air exposure, resulting in inefficient dosing and movement issues.
Innovation Solution
A make-up item with an applicator and a dispenser featuring an outer valve that controls product release directly onto the applicator, minimizing air exposure and using a flexible pouch and pump for precise product delivery, eliminating the need for a wiper and optimizing product distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a wiper is used to remove excess product from the applicator, then product wastage is reduced, but the applicator is subject to geometrical constraints and creates swabbing phenomena that hinder free movement
Solution Approach 1:
The invention removes the wiper component entirely from the system. Instead of using a wiper to remove excess product, the patent employs a valve-controlled dispensing mechanism that delivers the precise amount of product directly to the applicator, eliminating the need for product removal and avoiding all associated movement constraints and swabbing phenomena.
Solution Approach 2:
The valve is positioned and configured to dispense product onto the applicator before the applicator is inserted into the vial. This preliminary dosing action ensures the exact required amount of product is applied in advance, eliminating the need for subsequent product removal by a wiper and preventing any movement restrictions during insertion and extraction.
2Manufacturing precision
If a wiper is used to control product dosing on the applicator, then product distribution is improved, but the applicator requires a tapered shape that offers no benefit for the make-up result
Solution Approach 1:
The invention extracts the wiper component from the system and replaces it with a valve-based dosing mechanism. The valve controls product delivery through dispensing openings that face the applicator, achieving precise dosing without requiring any modification to the applicator's shape. The applicator maintains its optimal tapered geometry for make-up application.
Solution Approach 2:
The valve acts as an intermediary device between the product container and the applicator. It precisely controls product dosing through its dispensing openings and mechanical actuation, eliminating the need for direct contact between a wiper and the applicator surface, thereby preserving the applicator's ideal shape for make-up results.
3Ease of operation
If the vial is not completely filled with product to maintain free air volume for pressure equalization, then swabbing is reduced, but the overall device volume increases
Solution Approach 1:
The valve dispenses the precise amount of product onto the applicator before insertion into the vial. This preliminary dosing eliminates the need for swabbing actions during insertion and extraction, allowing the vial to be completely filled with product without requiring additional free air volume for pressure equalization.
Solution Approach 2:
By removing the wiper component and its associated swabbing phenomenon, the invention eliminates the need for free air volume in the vial. The valve-controlled system prevents pressure variations during applicator movement, enabling complete product filling of the vial and reducing the overall device volume.
4Loss of substance
If the valve opens and closes at the dispensing openings, then product control is optimized and air exposure is minimized, but the valve mechanism becomes more complex
Solution Approach 1:
The valve mechanism is designed to automatically open and close at the dispensing openings through its own mechanical structure. The valve body and actuation system work together to control product flow without requiring external complex control mechanisms, achieving optimized product dispensing and minimal air exposure through self-contained operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures optimal product control and minimization of wastage by releasing the precise amount of product directly onto the applicator, reducing air exposure and preventing drying, while simplifying the dispenser design and user operation.
Implementation Method 1
The dispenser also comprises a pump, without air intake, for supplying the valve with make-up product
Implementation Method 2
having at least one outer valve provided with at least one dispensing opening which faces a portion of the envelope surface when the applicator is received in the site, the valve being able to assume a closed position and an open position wherein the valve releases product directly against the head of the applicator
