Liquid Discharging Vessel Nozzle Dynamics for Contamination Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid discharging vessels with application tips are prone to contamination due to exposure of the nozzle outlet, allowing foreign matters to enter and compromise the content.
Innovation Solution
A liquid discharging vessel design featuring a nozzle that ascends and descends relative to the application tip, with the outlet only exposed when necessary, ensuring the nozzle outlet is not directly exposed to the outside, thus preventing contamination and maintaining the application tip's cleanliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the outlet is formed on top of the application tip for direct contact with user's application portion, then the content can be transferred to user without manual transfer, but the outlet is exposed to outside and foreign matters can be introduced causing contamination
Solution Approach 1:
The nozzle is designed to move relative to the application tip, transitioning between a descended position where the outlet is exposed for content discharge and an ascended position where the outlet is retracted and protected. This dynamic positioning allows the system to adapt between operational and protective states, resolving the contradiction between ease of content transfer and prevention of contamination.
Solution Approach 2:
The discharge system is divided into two functional components: the application tip that contacts the user and the nozzle that dispenses content. By separating the outlet function from the application tip surface, the design allows the outlet to be positioned on the nozzle body rather than directly on the tip, enabling protective retraction while maintaining operational effectiveness.
2Ease of operation
If the outlet is always exposed to outside for easy access, then content discharge is convenient, but foreign matters can enter the outlet causing contamination
Solution Approach 1:
The movable nozzle provides dynamic control over outlet exposure, being positioned in a descended state during content discharge for convenience and in an ascended state during storage or non-use periods for protection. This dynamic mechanism ensures the outlet is exposed only when necessary, maintaining both operational convenience and content purity.
3Ease of operation
If the application tip rubs against user's application portion, then content is transferred to user, but foreign matters are introduced into the outlet formed on application tip
Solution Approach 1:
The system separates the application tip surface from the nozzle outlet, with the outlet positioned on the nozzle body rather than directly on the tip. This segmentation allows the application tip to rub against the user's skin for effective content transfer while the nozzle outlet remains protected from direct contact with external environments, preventing foreign matter introduction.
Solution Approach 2:
The nozzle acts as an intermediary component between the content source and the application tip. By positioning the outlet on the nozzle rather than directly on the application tip, the design creates a protective barrier that prevents foreign matters from the application environment from entering the content discharge pathway while still enabling effective content transfer.

AI summary
Provided is a liquid discharging vessel including: a pump for discharging content; an application tip descended to operate the pump; and a nozzle exposed upwardly from the application tip when the application tip is descended and having an outlet adapted to discharge the content to top of the application tip, the outlet being closed by the application tip ascended.
