Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filling technologies struggle to accurately fill highly viscous materials into containers due to difficulties in maintaining quantitative tolerances, especially in dental applications, where legal regulations and precision are critical, and conventional methods rely heavily on operator skill and are prone to errors.
Innovation Solution
A device comprising a material container with dispensing nozzles and a movable carrier system, where dynamic pressure generated during filling is counteracted by a controlled counterforce, allowing for precise movement and adjustment of the carrier to ensure accurate filling volumes, with parameters like pressure and flow behavior being dynamically regulated to maintain consistent filling accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional filling methods are used for highly viscous materials, then the filling process is simple, but quantitative tolerances cannot be maintained
Solution Approach 1:
The carrier is designed to be movable relative to the first component during the filling process, allowing dynamic adjustment of the filling position and speed to adapt to the material's flow behavior and maintain quantitative tolerances
Solution Approach 2:
A controller is introduced that receives feedback about the filling process and adjusts the counterforce and filling parameters in real-time to maintain precise quantitative control despite variations in material viscosity and flow characteristics
2Productivity
If dynamic pressure is used to move the carrier, then filling speed increases, but quantitative tolerances deteriorate
Solution Approach 1:
A counterforce mechanism is introduced that exerts a defined opposing force to the dynamic pressure, balancing the carrier movement to maintain precise positioning and quantitative tolerances while still allowing controlled movement for efficient filling
Solution Approach 2:
The controller dynamically adjusts the counterforce parameter based on feedback from the filling process, optimizing the balance between filling speed and precision by changing the counterforce magnitude to match material flow characteristics
3Manufacturing precision
If operator skill is relied upon for filling, then equipment complexity is reduced, but filling accuracy varies
Solution Approach 1:
The filling system is designed to automatically regulate its own operation through the controller that monitors and adjusts filling parameters based on feedback, eliminating the need for operator skill while maintaining consistent quantitative tolerances
Solution Approach 2:
Manual operator control is replaced with an automated control system that uses sensors and controllers to regulate the filling process, substituting human skill with electronic control mechanisms that provide consistent, repeatable results

AI summary
The invention relates to a filling device (1) comprising a first component (2) and a second component (3). The first component (2) comprises a dosing cylinder (20) having a high-viscosity material (4) arranged therein. The second component (3) comprises a workpiece carrier (30) and a receiving carrier (31). The receiving carrier (31) is movably connected to the workpiece carrier (30). The movement v of the receiving carrier (31) during the filling process is determined by both the dynamic pressure exerted by the composite (4) flowing out onto the receiving carrier (31) and by the counterforce G against the dynamic pressure generated by a proportional pneumatic unit (35).
