Adjustable Fluid Dispenser With Rotating Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid dispensers, such as measuring cups, often have small and difficult-to-see markings, leading to inaccuracies in measuring and dispensing fluids, particularly in applications like medicine dosing.
Innovation Solution
A fluid dispenser with an adjustable measurement chamber and a rotating valve system that allows users to select and accurately dispense a preselected volume of fluid by aligning or misaligning fluid flow passages, ensuring precise fluid control and easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional measuring cups with small integral markings are used, then the device structure is simple, but the measurement precision deteriorates due to difficult-to-see markings
Solution Approach 1:
The dispenser is divided into multiple chambers (storage chamber, measurement chamber, dispensing chamber) with distinct functions. The measurement chamber is further segmented with multiple graduated markings to indicate different fluid volumes, allowing users to select and measure different dosages accurately without requiring a single complex marking system.
Solution Approach 2:
A valve mechanism acts as an intermediary between the storage chamber and measurement chamber, and another valve controls fluid flow from the measurement chamber to the dispensing chamber. These intermediary components enable precise control of fluid transfer and dispensing while maintaining clear visual measurements in the measurement chamber.
2Adaptability or versatility
If fixed measurement volumes are used, then the device complexity is reduced, but the adaptability deteriorates as users cannot adjust to different dosage requirements
Solution Approach 1:
The measurement chamber is designed with dynamic adjustability through multiple graduated markings that allow users to select different fill volumes based on dosage requirements. The valve mechanisms provide dynamic control over fluid flow timing, enabling the system to adapt to different measurement and dispensing needs while maintaining a relatively simple overall structure.
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 adjustable fluid dispenser provides improved accuracy and ease in measuring and dispensing fluids, allowing users to select from multiple graduated volumes, enhancing user interaction and preventing leakage or over-dispensing.
Implementation Method 1
at least one valve that is movable between a first position in which the at least one fluid flow passage is opened to permit fluid flow from the storage chamber to the measurement chamber, and a second position in which the at least one fluid flow passage is closed to prevent fluid flow between the measurement chamber and the storage chamber

AI summary
A measured fluid dispenser for dispensing fluid from a storage container includes a measurement chamber, a fluid flow passage fluidly connecting the measurement chamber with the storage container, and a valve that is movable between an open position in which the fluid flow passage is opened to permit fluid flow from the storage chamber to the measurement chamber, and a closed position in which the fluid flow passage is closed to prevent fluid flow between the measurement chamber and the storage chamber. The measurement chamber may be adjustable to vary a fillable volume of the measurement chamber to thereby preselect an amount of fluid to be dispensed. The valve may be a rotating valve including first and second valve parts which may form a divider of the dispenser that separates the measurement chamber from the storage container.
