Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filling flow dividers face challenges in ensuring uniform filling and preventing pressure fluctuations, which lead to inaccuracies in portioning fillers with different viscosities and components, resulting in potential changes in the filler's structure and mixture.
Innovation Solution
A filling flow divider design featuring at least two plate elements with rotors and vane elements that are connected via offsetting rotational angles, allowing for partial communication between sub-chambers to equalize pressure and reduce stress on the filler, ensuring even intake and delivery without pressure peaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a filling flow divider is used to distribute fillers to different filling areas, then the filler can be portioned and distributed to multiple containers, but pressure fluctuations and pressure peaks occur during the filling and emptying process, causing inaccuracies in portioning
Solution Approach 1:
The filling flow divider is divided into multiple independent dividing elements (at least two), each with its own rotor and vane elements. This segmentation allows different sub-chambers to operate semi-independently, reducing the impact of pressure fluctuations on overall portioning accuracy while maintaining high productivity through parallel filling operations.
Solution Approach 2:
The patent introduces a temporal dimension to the filling process by offsetting the rotational angle positions of rotors in different dividing elements. This creates a phased operation where sub-chambers are filled and emptied at different times, smoothing out pressure fluctuations and improving portioning accuracy without sacrificing productivity.
2Speed
If rotors are rotated to distribute filler, then filling speed is maintained, but pressure peaks occur during filling and emptying of sub-chambers, causing filler segregation and structural changes
Solution Approach 1:
The patent implements periodic action through the rotational movement of rotors with offset angular positions. Each rotor periodically fills and empties its sub-chambers in a phased sequence, creating a continuous and smooth filler flow that maintains filling speed while avoiding pressure peaks that could cause filler segregation or structural changes.
3Productivity
If multiple dividing elements are used to increase filling capacity, then productivity is improved, but the device complexity increases with additional rotors and vane elements
Solution Approach 1:
Each dividing element is designed as a universal module that can be replicated and combined. The rotors, vane elements, and housing components serve multiple functions: they distribute filler, portion it accurately, and their offset rotational positions automatically smooth pressure fluctuations. This multi-functionality allows increased productivity through modular addition without proportionally increasing overall system complexity.
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
This design achieves more uniform and precise portioning of fillers, reducing the risk of filler segregation and changes in its structure, while eliminating the need for pressure sensors and control systems, ensuring consistent flow and filling accuracy.
Implementation Method 1
vane elements are inserted, which are slidably movable in openings in the rotor and are pressed by a spring away from the rotor axis in the radial direction outwards
Implementation Method 2
a filler supplied to the filling flow divider is introduced into the filling flow divider and distributed to the individual filling areas by rotating devices, portioning being achieved
Implementation Method 3
a rotational angle position of the rotor and the associated wing elements of one of the dividing elements around the axis of rotation is different from a rotational angle position of the rotor and the associated wing elements of the other dividing element. The partial chambers of the respective divider elements, which are offset relative to one another by the predetermined angle of rotation, communicate with one another
