Solution Overview

Problem

Conventional cosmetic product applicators, such as those for mascara, often require radial pressure to dispense the product, which can be uncomfortable for users and does not allow for easy control over the amount of product released.

Innovation Solution

A dual-part applicator with a mobile and fixed component that translates between retracted and deployed positions, forming a variable volume reservoir, allowing for easy product dispensing and control without needing to press on the application surface, and enabling suction of excess product.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If radial pressure is applied to dispense cosmetic product, then product dispensing is achieved, but user comfort deteriorates and control over product amount becomes difficult

Engineering Contradiction:
Improveuser comfortVSAvoidcontrol over product amount
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The applicator employs a mobile part that can translate relative to a fixed part, dynamically adjusting the reservoir volume during application. This dynamic mechanism allows the user to control product dispensing by simply moving the applicator back and forth, eliminating the need for radial pressure while maintaining ease of operation and precise control over product amount.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If radial pressure is used to extract cosmetic product, then product dispensing is enabled, but the application process becomes complex and less pleasant

Engineering Contradiction:
Improveapplication process simplicityVSAvoidproduct dispensing reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The applicator design allows the cosmetic product to be dispensed automatically through the translational motion of the mobile part relative to the fixed part. The mechanism self-regulates product flow based on the volume change during translation, eliminating the need for manual pressure application while ensuring reliable product dispensing throughout the application process.

Inventive Principle:
Principle #25Self-service

AI summary

The invention relates to an applicator for a cosmetic product including a first part and a second part that extend along a longitudinal direction of extension from a proximal end towards a free distal end of the applicator, the first part and the second part being configured to form parts for applying the cosmetic product, one of the parts is mounted mobile in for translational with respect to the other of the parts, from at least a first retracted position, to a second deployed position, the first and second parts are configured to form together a variable volume reservoir, intended to contain the cosmetic product and that has a first volume when the parts occupy the first retracted position and a second volume when the parts occupy the second deployed position.
