Dispensing Device Dividing Wall Turbulence Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for dispensing substances via air lack efficient mechanisms for breaking down substances into small, inhalable particles, and often fail to provide effective sealing and turbulence at the discharge nozzle.
Innovation Solution
A device with a dividing wall in the emptying area, made of hard material with a soft end face, creates a bypass air flow path and favorable turbulence at the discharge nozzle, utilizing a connecting duct and a piercing device with projections to ensure sealing and efficient substance dispersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a hard dividing wall is used in the emptying area, then structural strength and sealing stability are improved, but sealing effectiveness against the foil cover deteriorates
Solution Approach 1:
The dividing wall is constructed as a composite structure with a hard material body providing structural strength and a soft material coating on the foil-contact surface providing sealing effectiveness. This composite design resolves the contradiction by combining materials with complementary properties - the hard portion maintains structural integrity while the soft portion conforms to the foil cover for reliable sealing.
2Device complexity
If air flow path is simplified, then device complexity is reduced, but turbulence and substance breakdown effectiveness deteriorate
Solution Approach 1:
The air duct system is segmented into multiple pathways including a first air duct for substance-laden air, a second air duct for clean air, and connecting channels that create controlled turbulence zones. This segmentation allows the system to maintain relatively simple overall structure while incorporating specific turbulence-generating sections that enhance substance breakdown efficiency without requiring complex mechanical components.
3Productivity
If chamber emptying is made complete, then substance delivery is improved, but risk of substance residue and contamination increases
Solution Approach 1:
The system uses controlled air flow through specifically designed ducts and channels to create pneumatic cleaning action. Air flows through the chamber cavity and emptying area to吹扫 any residual substance, ensuring complete emptying while simultaneously removing contaminants. The pneumatic flow pattern is designed to reach all chamber surfaces and carry residues out through the discharge nozzle.
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 device effectively breaks down substances into small, easily inhalable particles by creating turbulence and ensures complete emptying of the chamber, with the soft material sealing against the foil cover for efficient air flow and substance release.
Implementation Method 1
a soft material, which in an overlap to a substance-containing chamber cavity has a foil cover and the partition by means of this soft material rests sealingly on the foil cover
Implementation Method 2
An inflow direction of air flowing through an inflow opening in the first air duct is perpendicular to a flow direction of the air laden with substance in the first air duct in the area of the inflow opening. Due to the air streams meeting in the area of the inflow opening, favorable turbulence occurs in the area of the discharge nozzle. This achieves a further breakdown of the substance, so that the desired very small particles, which are easy to inhale, can occur.
