Shaking Element Vibration for Powder Compaction and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filling systems for powders, such as laundry detergents, face challenges in filling containers to the brim due to the formation of a loose conical heap, which obstructs the sealing process and impairs the quality of the seal, preventing complete utilization of the container volume.
Innovation Solution
A filling system where a shaking element with a shaking drive is used to compact and level the powder, with a shaking projection extending from the bottom edge, allowing only partial projection into the container to prevent contact and ensure the container is filled to the brim without disturbing the sealing surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bulk material cone is kept low to avoid obstructing the sealing process, then the sealing quality is improved, but the container cannot be filled to the brim and container volume utilization is reduced
Solution Approach 1:
The patent employs a shaking element with a shaking drive that vibrates during the filling process. This vibration compactes the powder as it is being filled, allowing the container to be filled to the brim without forming a loose conical heap that would obstruct sealing. The vibration transforms the loose bulk material into a compacted state, resolving the contradiction between filling height and sealing quality.
Solution Approach 2:
The shaking element is designed to be movable and is actively vibrated during filling. This dynamic approach allows the system to adapt the compaction level during the filling process, enabling maximum container utilization while maintaining sealing quality through real-time vibration-based compaction.
2Productivity
If the bulk material cone is allowed to be high to fill the container to the brim, then container volume utilization is improved, but the sealing process is obstructed and seal quality is impaired
Solution Approach 1:
The shaking element vibrates the powder during filling, compacting it to allow the container to be filled to the brim. This vibration prevents the formation of a loose conical heap that would otherwise obstruct the sealing process, thus achieving both high container utilization and maintained sealing quality.
Solution Approach 2:
The patent changes the physical state parameter of the powder from loose bulk material to compacted material through vibration. This parameter change allows the powder to be filled to the brim while maintaining a surface suitable for sealing, resolving the contradiction between filling height and sealing quality.
3Productivity
If a shaking element is used to compact and level the powder, then container volume utilization is improved, but the device complexity increases
Solution Approach 1:
The shaking element serves multiple functions: it compacts the powder, levels the surface, and prevents conical heap formation. By combining these functions into a single element, the system achieves high container utilization without proportionally increasing complexity, as one component performs multiple tasks.
Solution Approach 2:
The shaking element combines compaction and leveling functions in a single component. This merging of functions reduces the overall number of separate components needed, thereby limiting the increase in device complexity while achieving the desired container volume utilization.

AI summary
A filling system for filling powder into a target container to be sealed has a metering device for metering a partial quantity of the powder to be filled in. A compaction element for the powder is arranged below the metering device. The compaction element can be lowered from above into the target container. The compaction element is a shaking element with a shaking drive. During filling of the target container with the powder, the shaking element at least partially projects from above into the target container. The shaking element has a bottom edge provided with a shaking projection, wherein the shaking projection, beginning at the bottom edge, extends downwardly. During filling of the target container with the powder, only the shaking projection of the shaking element projects from above into the target container and the shaking element as a whole does not contact the target container.
