Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dosage-dispensing devices for powders often clog due to clumping and compressibility issues, leading to difficulties in dispensing materials like cornstarch, which requires complex mechanisms with movable parts that can cause wear and damage.
Innovation Solution
A dosage-dispensing device with a base unit, receiving unit, and actuator that generates bidirectional pivoting and translatory movements to agitate the dosage material, preventing clumping without internal movable parts, using a single or dual actuator system to optimize flow through the dispensing orifice.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a narrow discharge orifice is used to dispense dosage material into small target containers, then filling precision and targeted stream delivery are improved, but clogging due to particle clumping and compressibility increases
Solution Approach 1:
The patent employs a vibrating element that contacts the dosage material in the source container to induce vibrations, preventing particle clumping and compressibility issues. This mechanical vibration keeps particles loose and flowing, ensuring reliable dispensing through the narrow discharge orifice without clogging.
Solution Approach 2:
The patent uses periodic tapping or vibrating actions applied to the source container or dosage material to regularly prevent clump formation. This periodic mechanical stimulation maintains particle flowability throughout the dispensing process, addressing the clogging problem while preserving precise delivery through the narrow orifice.
2Productivity
If conveyor screws or stirring devices are used to move dosage material, then material flow and clogging prevention are improved, but device complexity and mechanical wear increase
Solution Approach 1:
The patent removes complex internal conveyor mechanisms and stirring devices from the dosage-dispensing unit. Instead, it applies external or minimal vibration to the dosage material itself, extracting the need for complex mechanical conveyance systems while maintaining effective material flow and clogging prevention.
Solution Approach 2:
The dosage material is enabled to flow freely through self-service mechanisms such as gravity flow enhanced by minimal vibration, eliminating the need for external conveyor screws or stirring devices. The system allows the material to serve its own transportation function without complex mechanical assistance.
3Reliability
If tapping and vibrating devices are applied to the source container, then clogging is reduced, but device complexity increases
Solution Approach 1:
The patent combines the vibrating element directly with the dispensing head or integrates it into the existing source container structure, merging the anti-clogging function with the dispensing mechanism. This integration reduces overall device complexity while maintaining effective vibration application to prevent clogging.
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 loosens and separates the dosage material, reducing clogging and improving flow behavior by superimposing pivoting and translatory movements, allowing for precise control of the dispensing process without internal mechanical wear, suitable for powders and other substances with complex rheological properties.
Implementation Method 1
the actuator has the capability to generate repeated bidirectional pivoting movements of the receiving unit... the receiving unit can be subjected to repeated bidirectional pivoting movements and, superimposed on the latter, repeated bidirectional translatory movements
Implementation Method 2
Propelled by gravity, free-flowing dosage material inside the dosage-dispensing unit flows towards the discharge orifice

AI summary
A device (110, 10) dispenses dosages of a free-flowing substance from a source unit (70) containing the substance. The device has a base unit (120, 20) and a receiving unit (130, 30), so that the source unit can be set into, and removed from, the receiving unit. An actuator (150, 50) generates repeated bidirectional pivoting movements of the receiving unit about the base unit. A connector unit (140, 40), arranged between the base unit and the receiving unit, pivotally supports the receiving unit, providing rotational mobility about a pivoting axis. The connector unit is slidably supported with translatory mobility relative to the base unit. The actuator generates repeated bidirectional translatory movements of the base unit. In this way, the receiving unit is subjected to repeated bidirectional pivoting movements and, superimposed on the latter, repeated bidirectional translatory movements.
