Solution Overview

Problem

Existing systems face challenges in efficiently distributing extraction material to multiple extraction chambers, leading to increased extraction time and reduced throughput of beverages like coffee or tea, as they struggle to provide a consistent and controlled amount of extraction material to each chamber.

Innovation Solution

A system comprising a hopper, grinder, distributor, and gates is used to distribute extraction material to multiple extraction chambers, ensuring a predetermined amount is provided to each chamber, with features like rotating gates and piezoelectric actuators to prevent material sticking, allowing simultaneous extraction across multiple chambers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single extraction chamber system is used, then the system complexity is low, but the productivity is limited due to sequential processing

Engineering Contradiction:
Improvebeverage production rateVSAvoiddistribution system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system divides the extraction process into multiple parallel chambers (first extraction chamber, second extraction chamber, etc.), each receiving extraction material through separate distribution paths. This segmentation enables simultaneous extraction operations across multiple chambers, thereby increasing overall productivity without requiring a proportional increase in system complexity through the use of a centralized distribution mechanism

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The distribution mechanism serves multiple functions: it can selectively supply extraction material to different chambers based on their readiness status, control the timing of material transfer, and maintain consistent material distribution across all chambers. This multi-functionality allows a single distribution system to manage multiple extraction chambers efficiently, improving productivity without proportionally increasing complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Manufacturing precision

If manual distribution of extraction material is used, then the device complexity is low, but the manufacturing precision of material distribution is inconsistent

Engineering Contradiction:
Improveextraction material distribution consistencyVSAvoiddistribution mechanism complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The distribution mechanism automatically detects when extraction chambers are ready to receive material and initiates material transfer without manual intervention. The system self-regulates the distribution process, ensuring consistent material allocation to each chamber based on their extraction cycle status, thereby achieving precise material distribution through automated control rather than manual operation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system incorporates sensors or detection mechanisms that monitor the status of extraction chambers and provide feedback to the distribution mechanism. This feedback enables the distribution system to adjust material supply timing and quantity based on real-time chamber conditions, ensuring consistent and precise material distribution across all chambers while maintaining relatively simple device architecture

Inventive Principle:
Principle #23Feedback

3Productivity

If extraction material is continuously supplied to multiple chambers, then the productivity is high, but the loss of substance occurs due to material waste

Engineering Contradiction:
Improveextraction processing speedVSAvoidextraction material waste
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The distribution mechanism operates periodically, supplying extraction material to chambers only when they are ready to receive it (i.e., when their previous extraction cycle is complete). This periodic, demand-driven distribution approach maintains high productivity by keeping all chambers actively processing while preventing material waste through targeted, timely delivery rather than continuous supply

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system prepares extraction material in advance and holds it ready for distribution, then releases it to specific chambers at the precise moment they need it. This preliminary preparation combined with timed delivery ensures that material is always available for immediate processing when chambers are ready, maintaining high throughput while minimizing waste by avoiding premature or unnecessary material supply

Inventive Principle:
Principle #10Preliminary action
