Measuring Dispenser With Linked Gates For Sequential Volume Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for dispensing measured amounts of materials lack efficiency and precision, particularly for finely comminuted and loose granular substances, as they often require manual operation and struggle with sequential dispensing of multiple chambers without over-dispensing or under-dispensing.
Innovation Solution
A device with an inner and outer gate mechanism, linked by a central member, allows for sequential filling and dispensing of multiple chambers by rotating the gates relative to each other, ensuring precise control over the dispensing volume through distinct positions and stops to prevent over-dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing devices are used for dispensing measured amounts of materials, then manual operation is required, but efficiency and precision deteriorate due to inability to sequentially dispense multiple chambers without over-dispensing or under-dispensing
Solution Approach 1:
The device divides the dispensing system into multiple separate dispensing chambers (at least three) that can be independently filled and sequentially activated. Each chamber is separated by partition walls, allowing independent control of material release from each chamber through individual gates, enabling precise sequential dispensing without over or under-dispensing
Solution Approach 2:
The device employs movable gates (inner and outer gates) that can dynamically open or close to control material flow from each chamber. The gates are linked so that opening one gate corresponds to opening another, providing dynamic control over the dispensing process. The system transitions from static manual operation to dynamic automated control where the state of gates changes based on dispensing requirements
2Measurement precision
If multiple chambers are dispensed sequentially, then desired volume control is improved, but device complexity increases due to need for linked gate mechanisms and positional control
Solution Approach 1:
The device combines multiple control functions into a unified gate mechanism. The inner gate and outer gate are linked together, so that controlling one gate automatically controls the other. This merging of control functions reduces the complexity that would otherwise result from having to independently control multiple gates, while still achieving precise sequential dispensing from multiple chambers
Solution Approach 2:
The linked gate mechanism serves multiple functions simultaneously: it controls opening/closing of both inner and outer gates, enables sequential chamber activation, and provides volume measurement control. This multi-functionality reduces the need for separate control mechanisms for each function, thereby managing device complexity while achieving precise volume control
3Measurement precision
If distinct filling and dispensing apertures are used, then dispensing precision is improved, but device complexity increases due to additional structural components
Solution Approach 1:
The device employs asymmetric positioning of the filling aperture and dispensing aperture within each chamber. The filling aperture is positioned at one location on the chamber wall while the dispensing aperture is offset to a different location. This asymmetric arrangement allows material to be filled through one aperture and dispensed through another, preventing contamination and enabling precise control over when and how material is released, thereby improving dispensing accuracy

AI summary
A device for dispensing spices and similar materials. The device includes a chamber member, an inner gate above the chamber member and an outer gate below the chamber member. The inner gate contains a filling aperture and the outer gate contains a dispensing aperture which is offset from the filling aperture. The chamber member contains dispensing chambers, each having an open top and an open base, and a non-dispensing chamber having a closed top. The inner and outer gates are linked together and can be rotated relative to the chamber member, so that material can be loaded through the filling aperture or dispensed through the dispensing aperture.
