Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If capsule handlers are made symmetrical for simplicity, then device complexity is reduced, but capsule alignment precision deteriorates leading to increased vibrations and wear

Engineering Contradiction:
Improvecapsule handler structureVSAvoidcapsule alignment precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent applies asymmetry by providing capsule handlers with different asymmetrical configurations. Specifically, the first capsule handler has a first asymmetrical configuration while the second capsule handler has a second asymmetrical configuration that is different from the first. This asymmetrical design enables precise angular positioning of capsules during centrifugation, thereby improving alignment precision and reducing vibrations without excessive complexity

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The patent implements dynamics through a positioning device that can actively adjust and reposition the capsule handlers angularly. The positioning device includes a motorized mechanism capable of rotating the capsule handlers to predetermined angular positions, allowing dynamic adjustment during operation to maintain precise alignment and compensate for any misalignment that may occur

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If capsule handlers are positioned at arbitrary angular positions, then ease of operation is improved, but stability during centrifugation deteriorates due to vibrations

Engineering Contradiction:
Improvecapsule transfer operationVSAvoidcentrifugation stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action by pre-defining specific predetermined angular positions for the capsule handlers before centrifugation begins. The positioning device is configured to automatically position the handlers at these predetermined angles, ensuring optimal alignment is achieved before the centrifugation process starts, thereby maintaining stability throughout operation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback through a control system that monitors the angular positions of the capsule handlers and adjusts them accordingly. The system receives signals about the current position and makes corrective adjustments to maintain the predetermined angular positions, providing feedback control that ensures both ease of operation and centrifugation stability

Inventive Principle:
Principle #23Feedback

3Productivity

If capsule alignment is not precisely maintained, then productivity is improved through faster operation, but reliability deteriorates due to increased wear and vibrations

Engineering Contradiction:
Improvebeverage preparation speedVSAvoidmachine durability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies self-service through an automated positioning system that automatically adjusts and maintains the angular positions of the capsule handlers without requiring manual intervention. The system self-corrects alignment issues during operation, ensuring precise capsule alignment is maintained throughout the beverage preparation process, thereby protecting machine components from excessive wear while maintaining high productivity

Inventive Principle:
Principle #25Self-service

AI summary

A capsule processing machine (1) is configured for preparing a beverage from a capsule (5) having a body containing an ingredient by circulating a liquid into such capsule (5) and centrifugally driving such capsule (5). The machine (1) has a first capsule handler (10) and a second capsule handler (20) that are movable one relative to the other from: a capsule transfer configuration for receiving/releasing the capsule (5); to a capsule processing configuration for centrifuging the capsule (5) about a processing axis (30'). At least one of the first and second capsule handlers (10,20) is fixed to or integral with or connected to a positioning device (30'',40'') configured to position such capsule handler(s) (10,20) at a predetermined angular position about the processing axis (30') when the capsule handlers (10,20) are in the capsule transfer configuration.
