Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wireless data transmission operates from inside the mixing container to the exterior control device, then data can be transmitted to the control system, but high transmission power is required and reliability decreases due to signal penetration through container walls

Engineering Contradiction:

Improvedata transmission reliabilityVSAvoidtransmission power

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

A stationary data interface is introduced as an intermediary component arranged inside the mixing container. This interface receives data from the rotating sensor system via contactless power transmission and transmits it to the exterior control device, thereby mediating between the rotating and stationary systems and eliminating the need for high-power transmission through container walls.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces mechanical contacting power transmission (slip rings) with contactless power transmission using electromagnetic fields. This substitution eliminates mechanical wear while enabling reliable data and power transmission between the rotating sensor system and the stationary data interface inside the container.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Use of energy by moving object

If contacting power transmission is used to supply power to the co-rotating sensor system, then power can be transmitted to the sensor, but mechanical wear occurs reducing reliability

Engineering Contradiction:

Improvepower transmission to sensorVSAvoidsystem reliability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent replaces mechanical contacting power transmission with contactless power transmission using electromagnetic induction. A transmitter coil arranged stationary in the mixing container generates an alternating magnetic field that induces current in a receiver coil on the rotating mixing member, thereby supplying power without mechanical contact and eliminating wear.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If the sensor system is arranged to co-rotate on the mixing member, then the sensor can examine fodder components during mixing, but controlling and powering the rotating sensor from the exterior becomes complex

Engineering Contradiction:

Improvesensor examination capabilityVSAvoidcontrol system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A stationary data interface inside the mixing container serves as an intermediary that receives data from the rotating sensor system and transmits it to the exterior control device. This intermediary simplifies the control architecture by providing a fixed communication point inside the container, reducing the complexity of controlling rotating components from the exterior.

Inventive Principle:

Principle #24Intermediary (Mediator)
