Cosmetic Auto Dropper with Nested Piston Hygiene
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic packaging methods, such as individual capsules and conventional syringe structures, are inefficient and unsanitary, leading to waste and inconvenience in using cosmetic liquids, particularly eye creams, due to exposure of the piston area and potential contamination.
Innovation Solution
A cosmetic auto dropper design featuring a container body with a pipette member, a cap part with an inner and outer cap, and an elastic part that supports a pumping mechanism for stable elevation and operation, allowing for precise suction and discharge of cosmetic liquids using a piston method, while maintaining hygiene by minimizing external exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional syringe structure is used to extract cosmetic contents, then the extraction function is achieved, but the piston area is exposed to the outside causing sanitation issues
Solution Approach 1:
The piston is nested within the syringe barrel, and the entire syringe assembly is nested within the container. The piston remains enclosed within the syringe structure throughout operation, preventing exposure to external contaminants while maintaining extraction functionality.
Solution Approach 2:
The syringe barrel acts as a protective shell enclosing the piston. This flexible yet protective enclosure allows the piston to move for extraction while preventing foreign substances from contacting the piston surface, solving the sanitation issue.
2Measurement precision
If individual capsule packaging is used for cosmetic contents, then precise quantity for each use is achieved, but a large amount of contents remains in the capsule causing waste
Solution Approach 1:
The system transitions from static individual capsules to a dynamic reusable container with a movable piston. The piston can be moved to extract contents gradually, allowing the user to access the entire quantity of cosmetic contents in the container over multiple uses, eliminating waste while maintaining precise quantity control through controlled piston movement.
3Ease of operation
If the pumping driving part is not stably elevated, then the structure is simpler, but the convenience of use is reduced
Solution Approach 1:
The syringe assembly is elevated to a position where the pumping action can be performed at an ergonomically suitable height for the user. This elevation, achieved through the container design, makes operation more convenient without requiring complex additional support mechanisms, as the elevation is integrated into the basic container structure.
