Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drives for containers struggle to provide a reciprocating movement along a trajectory curve without relying on linear guides or motors, limiting the ability to efficiently mix ingredients within the container.
Innovation Solution
A drive mechanism utilizing rotary motors and eccentric drives with levers and pivot bearings to create a reciprocating movement along a trajectory curve, allowing for the superposition of movements along multiple axes with different frequencies and phase offsets to generate a non-linear path for the container, enhancing mixing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a linear drive or link guide is used to move the container along a trajectory curve, then the container can be guided along a precise path, but the device complexity increases and gravity-dependent operation is required
Solution Approach 1:
The patent replaces traditional linear drives and link guides with a purely rotary drive mechanism. The container holder is driven exclusively by rotary motors that rotate about a vertical axis, eliminating the need for linear guides and complex mechanical linkages while maintaining trajectory guidance capability through controlled rotary motion and centrifugal forces
Solution Approach 2:
The system uses dynamic control of rotary motion to achieve trajectory guidance. By varying the rotation speed, acceleration, and phase relationships between multiple rotary drives, the container can be guided along different trajectory curves without requiring fixed mechanical guides or links
2Device complexity
If a rotary drive system is used instead of linear drive, then the device complexity is reduced, but achieving precise reciprocating movement along a trajectory curve becomes more difficult
Solution Approach 1:
The patent combines multiple rotary drive mechanisms working together to achieve complex reciprocating motion. By coordinating the rotation of multiple motors about a common vertical axis with different phases and speeds, the system generates the desired trajectory curves through the superposition of rotational movements, simplifying the overall mechanism while maintaining control precision
Solution Approach 2:
The system employs periodic rotary motion with controlled acceleration and deceleration phases to achieve reciprocating movement. The rotary drives operate in periodic cycles, rotating in one direction to move the container along the trajectory curve, then reversing to return it, creating the desired reciprocating pattern through timed periodic action

The drive effectively accelerates solids and liquids within the container, promoting intensive mixing by shearing against the container walls, independent of gravity, with adjustable trajectory curves and accelerations to optimize the mixing process.
Implementation Method 1
one or both of the eccentric drives can have a link guide, which extends along the lever driven by the eccentric drive, and a drive pin guided in the link guide and driven by a rotary motor
Implementation Method 2
A first lever (4) is articulated on a first stationary pivot bearing (1), opposite to the first pivot bearing a second lever (5) is articulated on the first lever (4) in a first connecting bearing (6)
Implementation Method 3
A first lever (4) is articulated on a first stationary pivot bearing (1), opposite to the first pivot bearing a second lever (5) is articulated on the first lever (4) in a first connecting bearing (6)
Implementation Method 4
The first stationary pivot bearing and the second stationary pivot bearing are fixed relative to each other, pivotable at a distance from each other or about the same pivot axis
Implementation Method 5

AI summary
A drive with which a container can be driven and positively guided in a plane along a trajectory curve, and a method for treating ingredients, in particular mixtures, in a container which is driven and positively guided along a trajectory curve by means of the drive. The drive has the advantage of using only rotary drives to move a container in a positively guided reciprocating movement along a trajectory curve.
