Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If linear guides and linear drives are used to achieve reciprocating movement along a trajectory curve, then the movement control is precise, but the device complexity increases and the ability to mix contents in three dimensions is limited

Engineering Contradiction:

Improvemovement control precisionVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces linear guides and linear drives with a purely rotary mechanical system. A pivot arm articulated to a stationary pivot bearing enables reciprocating movement through rotary motion of levers, eliminating the need for linear guide structures and linear drive mechanisms while maintaining precise trajectory control through geometric relationships in the rotary mechanism

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The device segments the reciprocating movement into two independent rotational movements of levers articulated to the pivot arm. Each lever can be driven by a separate motor or through a transmission mechanism, allowing independent control of movement components while achieving complex three-dimensional trajectories through the combination of these segmented motions

Inventive Principle:

Principle #1Segmentation

2Device complexity

If only rotary drives and rotary bearings are used, then the device complexity is reduced, but achieving three-dimensional reciprocating movement becomes more difficult

Engineering Contradiction:

Improvedevice complexityVSAvoidthree-dimensional movement capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent transforms linear reciprocating movement into rotational motion by using a pivot arm articulated to a stationary pivot bearing. The lever mechanisms convert rotary motion into reciprocating linear motion, effectively adding a dimensional transformation that enables three-dimensional movement capability through purely rotary components

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The pivot arm mechanism serves multiple functions: it provides the reciprocating movement trajectory, supports the levers that generate the motion, and enables three-dimensional movement capability. This universal mechanism achieves complex motion patterns through a single articulated structure rather than requiring separate mechanisms for each movement dimension

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If a single motor with intermediate transmission is used, then the device complexity is reduced, but the control precision of reciprocating movement may be compromised

Engineering Contradiction:

Improvedevice complexityVSAvoidcontrol precision

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The patent introduces an intermediate transmission mechanism between the motor and the levers. This transmission system acts as a mediator that converts rotary motor motion into precise reciprocating lever motion, maintaining control precision while reducing overall device complexity by consolidating drive sources

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The invention relates to a device which can be used as a drive, with which a container holder and a container fixed thereto can be driven and forcibly guided along a trajectory curve, and to a method for treating ingredients, in particular mixtures, in a container which is driven and forcibly guided along a trajectory curve by means of the device. The device has a pivot arm articulated to a first stationary pivot bearing, the pivot bearing being set up for pivoting along two axes which are arranged perpendicularly to the longitudinal axis of the first pivot arm, a container receptacle attached to the end of the pivot arm opposite the pivot bearing, and a container holder mounted on the end of the pivot arm opposite the pivot bearing, a first lever driven for reciprocating movement, which is articulated to the pivot arm at a spacing from the pivot bearing, and a second lever driven for reciprocating movement, which is articulated to the first pivot arm at a spacing from the pivot joint, wherein the first lever and the second lever are arranged to move the first pivot arm about the two axes of the first pivot bearing.
