Dental Paste Filling Chambers for Bubble-Free Deaeration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental paste filling technologies fail to efficiently defoam the paste and prevent air bubble entrainment during filling, leading to undesirable effects on physical properties and aesthetics, and potential paste deterioration due to oxygen exposure.
Innovation Solution
A dental paste filling device and method that includes a storage chamber with a depressurizing and defoaming device, a filling chamber with a deaerating device, and a controlled supply flow passage to separately manage defoaming and air bubble prevention, using a discharge control valve to ensure air-tight filling without bubbles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single large chamber is used to store and fill dental paste, then device complexity is reduced, but air bubble entrainment increases and defoaming efficiency decreases
Solution Approach 1:
The single large chamber is divided into two separate chambers: a storage chamber for holding dental paste and a filling chamber for transferring paste to containers. This segmentation allows independent control of defoaming in the storage chamber and air bubble prevention in the filling chamber, resolving the contradiction between device simplicity and air bubble control.
2Ease of operation
If a rotational drive mechanism is used to transfer material, then material transfer is achieved, but production efficiency decreases due to slow container replacement
Solution Approach 1:
The rotational drive mechanism is replaced with a pressure-based transfer system. A pressurizing device forces the dental paste through a supply flow passage into containers positioned in the filling chamber, eliminating the need for rotation and enabling rapid container replacement without compromising material transfer effectiveness.
3Object-generated harmful factors
If a large chamber is depressurized for defoaming, then paste defoaming is achieved, but energy consumption and processing time increase
Solution Approach 1:
The large chamber is segmented into a storage chamber and a filling chamber, each with independent depressurization capability. The storage chamber can be depressurized to defoam the paste, while the filling chamber maintains positive pressure or atmospheric pressure to prevent air bubble entrainment during filling, reducing the energy and time required compared to depressurizing a single large chamber.
4Device complexity
If defoaming and filling are performed in the same chamber, then device complexity is reduced, but manufacturing precision of paste quality decreases
Solution Approach 1:
The system segments the paste handling process into two distinct chambers: the storage chamber for defoaming and the filling chamber for air-tight filling. This allows independent optimization of each process - defoaming in the storage chamber without contamination from container air, and precise filling in the filling chamber with controlled atmosphere, thereby improving paste quality consistency.
