Solution Overview
Problem
Conventional dropper dispensers require complex hand gestures and are not always ready for use, leading to inefficiencies and potential product loss.
Innovation Solution
A dropper dispenser design featuring a bottle with a built-in pump system and a base with a locking mechanism, allowing for axial movement of the bottle to control product flow, thus simplifying the dispensing process and minimizing hand use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional dropper dispenser uses a simple elastomer teat for suction and discharge, then the device structure is simple, but the user must perform complex hand gestures and the device is not always ready for use
Solution Approach 1:
The patent merges the suction and discharge functions into a single integrated pump system. The pump assembly combines a piston, cylinder, inlet valve, and outlet valve into one unit that performs both suction (drawing product up) and discharge (delivering product out) through a single mechanical action of pressing the flexible membrane, eliminating the need for separate suction and discharge operations
Solution Approach 2:
The patent employs a dynamic pump mechanism with a movable piston and flexible membrane that changes its configuration during operation. The piston moves within the cylinder to create pressure differentials, and the flexible membrane deforms to drive the pumping action, enabling the device to transition between suction and discharge modes automatically based on the pressing action
2Reliability
If a conventional dropper dispenser requires manual suction and discharge operations, then the device structure is simple, but product loss and contamination risk increase
Solution Approach 1:
The patent extracts the product from direct contact with the external environment by using a closed pump system. The product is drawn up through an inlet valve into a sealed chamber, and discharged through a controlled outlet valve, preventing exposure to air and contaminants throughout the suction and discharge process
Solution Approach 2:
The patent introduces a flexible membrane as an intermediary between the user's finger and the product. The membrane transmits the user's pressing force to the piston and product without requiring direct contact with the product, maintaining product purity while enabling control
3Loss of substance
If the bottle is not always inverted in conventional dispensers, then the device structure is simple, but product restitution is incomplete leading to loss
Solution Approach 1:
The patent creates an equipotential condition for product flow by ensuring the outlet is always at the lowest point through the inverted bottle positioning. The pump system is designed to draw product from all parts of the bottle equally when inverted, maximizing product recovery without requiring complex mechanical positioning mechanisms
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
The dispenser is always ready for use, requires minimal hand movement, and maximizes product restitution by ensuring the bottle is inverted, reducing the risk of product loss and contamination.
Implementation Method 1
an axial displacement of the bottle from the lower position to the upper position causes air to move towards the bottom of the bottle, the air thus moved carrying with it the product present in the bottle
Implementation Method 2
The drops are dispensed one after the other. The drop(s) fall from the dispenser by gravity onto a desired application surface

AI summary
A cosmetic product applicator dispenser, including: a bottle with a longitudinal axis, forming a reservoir of product to be dispensed, a base serving as a support for the bottle, a locking system to lock the bottle on the base, the bottle, when locked on the base, axially movable between an upper and lower end position, a product dispensing area configured to allow the formation of drops of product, a pump system configured so that an axial displacement of the bottle from the lower position to the upper position causes air to move towards the bottom of the bottle, the air thus moved carrying with it the product present in the bottle to a product storage area, and so that an axial displacement of the bottle from the upper end position to the upper position causes the product to circulate from the product storage area to the dispensing area.
