Metering Bottle Structure for Spill-Free Granular Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dosing systems for granular materials require additional containers for metered delivery, leading to uncontrolled flow and spills during pouring.
Innovation Solution
A dosing bottle design featuring a metering chamber connected to a storage chamber via a metering opening with a predetermined cross section, allowing for gravity-fed filling and controlled pouring without an additional dosing container, utilizing a pouring channel with a larger cross section than the metering opening to prevent uncontrolled flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If granular material is freely accessible during pouring from the bottle into the dosing container, then filling is simplified, but uncontrolled flow and spills occur
Solution Approach 1:
The bottle is segmented into two functional chambers: a storage chamber for bulk material and a dosing chamber for metered delivery. The dosing chamber acts as an intermediate container that receives material through a restricted opening, enabling controlled pouring without direct access to the bulk storage, thus preventing spills while maintaining ease of operation
Solution Approach 2:
The dosing chamber serves as an intermediary between the storage chamber and the external environment. Material flows from the storage chamber through a metering opening into the dosing chamber, and then is poured from the dosing chamber. This intermediate step provides control over the flow rate and prevents uncontrolled spilling
2Reliability
If a dosing chamber with restricted opening is used to prevent uncontrolled flow, then pouring control is improved, but additional dosing container is required
Solution Approach 1:
The invention merges the storage function and dosing function into a single integrated bottle structure. The storage chamber and dosing chamber are combined in one vessel, with the dosing chamber forming part of the bottle body. This eliminates the need for separate dosing containers while maintaining precise pouring control through the restricted metering opening
3Measurement precision
If metering opening has predetermined cross section for precise dosing, then dosing precision is improved, but filling speed is reduced
Solution Approach 1:
The segmentation into storage chamber and dosing chamber allows the filling operation to occur at high speed into the dosing chamber without being constrained by the small metering opening dimensions. Once the dosing chamber is filled, the restricted opening ensures precise metering. This separates the filling speed function from the dosing precision function, allowing both requirements to be satisfied simultaneously
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
Enables precise dosing with a single tilt of the bottle, preventing uncontrolled flow and spills, and facilitating easy emptying of the dosing chamber without impairing the predetermined volume.
Implementation Method 1
the metering chamber can be filled with the granular material and this can be filled by gravity
Implementation Method 2
The dosing opening 3, which can also be designed as a connecting channel between the storage container 1 and the dosing chamber 2, has a predetermined cross section which is matched to the grain size of the bulk material 5 contained in the storage container 1
Implementation Method 3
this can be filled by gravity, optionally supported by shaking the bottle are then poured out of the dosing chamber
