Problem

Professional coffee machines require manual operations that can lead to inconsistent coffee quality due to user variability and differing ingredient treatments, making it complex to maintain consistent beverage quality over time and adapt to various beverage types.

Innovation Solution

A machine with a filter holder and piston that moves automatically under motor control to achieve consistent compression of ingredients, allowing for adjustable pressure settings based on operator input and environmental parameters, ensuring repeatable and high-quality beverage preparation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual compression of coffee powder is used, then the operator can control the compression process, but the coffee quality becomes inconsistent over time due to user variability

Engineering Contradiction:
Improvemanual compression controlVSAvoidcoffee quality consistency
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs compression automatically without requiring operator intervention. The motor-driven piston compresses the coffee powder based on pre-programmed parameters, making the system self-sufficient and eliminating variability introduced by different operators.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical compression operation is replaced by an automated motor-driven piston system. The control unit manages the compression process through electrical control of the motor, substituting human mechanical action with an automated electromechanical system that ensures consistent results.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If different treatments are applied for different beverages, then the machine can accommodate various beverage types, but the operational complexity increases for the operator

Engineering Contradiction:
Improvebeverage type accommodationVSAvoidoperational complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically adjusts compression parameters based on the selected beverage type. The control unit modifies piston movement characteristics, pressure levels, and compression duration according to pre-stored profiles for different beverages, enabling versatile operation without increasing user complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different beverage types are accommodated by changing compression parameters such as pressure, speed, and duration. The control unit stores multiple parameter sets corresponding to different beverages and automatically selects the appropriate parameters, allowing the system to adapt to various beverage requirements without complicating the user interface.

Inventive Principle:
Principle #35Parameter changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The machine ensures consistent coffee quality by automatically compressing ingredients to a predefined pressure, adapting to different beverages, and accounting for environmental factors, reducing operator fatigue and improving beverage consistency.

Implementation Method 1

The machine further comprises a motor adapted to relatively move the filter holder and piston between one another, so that to couple the piston with the seat obtained in the filter holder, thus defining an infusion chamber, and so that to compress the ingredient.

Methodology Applied
Scientific EffectCompression: Compression

Implementation Method 2

the control unit is configured so that to receive from an operator, directly or indirectly, a desired pressure value to be applied to the ingredients, and to relatively move the piston and the filter holder between one another until the pressure value of the piston on the ingredients is reached.

Methodology Applied
Scientific EffectPressure: Pressure Increase
