Solution Overview
Problem
Existing drive systems for containers lack the ability to provide a reciprocating motion along a three-dimensional path without linear guides or cam guides, limiting the efficiency of mixing and processing of ingredients.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If linear drives or cam guides are used to provide reciprocating motion along a three-dimensional path, then the motion control precision is improved, but the device complexity increases
Solution Approach 1:
The patent removes linear drives and cam guides from the system, extracting the problematic components that increase device complexity. The solution uses only rotary drives and rotary bearings to achieve the same reciprocating motion function, thereby reducing structural complexity while maintaining motion control capability through purely rotational mechanisms.
Solution Approach 2:
The patent replaces complex linear drive mechanisms with a simplified rotary drive system. By substituting linear actuation with rotational motion through levers and pivot bearings, the system achieves three-dimensional reciprocating motion without requiring linear guides or cam mechanisms, thus reducing device complexity.
2Device complexity
If a single motor with intermediate gearbox is used instead of two motors, then the device complexity is reduced, but the control flexibility may be compromised
Solution Approach 1:
The patent combines two separate motor functions into a single motor with an intermediate gearbox. The gearbox serves as a multiplier mechanism that can independently control the speed and direction of each lever, effectively merging two motor controls into one while maintaining the ability to independently adjust motion parameters through gear ratio selection.

Function Achieved in This Case
Enables efficient mixing of ingredients by generating a non-linear, three-dimensional reciprocating motion that intensively mixes solids and liquids within a container, independent of gravity, with adjustable acceleration and speed, enhancing mixing efficiency.
Implementation Method 1
Each lever can be driven by a separate eccentric drive, each with its own motor, or both levers can be driven by a common eccentric drive

AI summary
The invention relates to a device which can be used as a drive, with which a container receptacle (13) and a container fastened thereto can be driven and positively guided along a trajectory, and to a method for treating contents, in particular mixtures, in a container that is driven and positively guided along a trajectory by means of the device. The device has a pivot arm (10) articulated on a first stationary pivot bearing (1), wherein the pivot bearing is designed to pivot along two axes, which are perpendicular to the longitudinal axis of the first pivot arm, a container receptacle attached on the end (12) of the pivot arm lying opposite the pivot bearing, a first lever (14a) driven to move back and forth, which is articulated on the pivot arm at a distance from the pivot bearing, and a second lever (14b) driven to move back and forth, which is articulated on the first pivot arm at a distance from the pivot bearing, wherein the first lever and the second lever are designed to move the first pivot arm about the two axes of the first pivot bearing.
