Solution Overview

Problem

Current automatic beverage preparation machines lack flexibility in operating modes and fail to efficiently manage brewing group failures or imbalances, leading to reduced capacity and quality when one brewing group malfunctions or runs out of coffee.

Innovation Solution

An automatic beverage preparation machine with a double brewing group system, featuring a user-selectable electronic control unit that allows for various production modes, including parallel, diversified, mixing, and long beverage production, and includes backup functionality and load balancing to distribute production evenly between brewing groups, ensuring continuous operation and extended lifespan.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single brewing group is used, then the device complexity is reduced, but the productivity and operating flexibility are limited

Engineering Contradiction:
Improvebeverage production capacityVSAvoidbrewing group configuration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system divides the brewing function into separate brewing groups (first brewing group for espresso, second brewing group for other beverages) that can operate independently or in coordination, allowing parallel production of different beverage types while maintaining manageable complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second brewing group is designed with multi-functionality to produce various beverages (freshly brewed coffee, tea, cocoa, etc.) using the same basic brewing mechanism, enabling a single device to handle diverse beverage preparation needs without requiring separate specialized equipment for each type

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

2Adaptability or versatility

If two brewing groups produce different beverage types, then the adaptability is improved, but the reliability decreases when one group fails

Engineering Contradiction:
Improvebeverage type varietyVSAvoidservice continuity
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The electronic control unit dynamically assigns beverage production tasks to available brewing groups based on real-time operational status, allowing the system to adapt its configuration and maintain service continuity by redirecting requests from failed groups to functional groups

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements backup functionality where the electronic control unit monitors brewing group status and pre-plans alternative production assignments, ensuring that when one brewing group fails, the other can immediately compensate to maintain service without interruption

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Ease of operation

If brewing groups operate independently, then the ease of operation is improved, but the loss of time increases due to unbalanced wear and failures

Engineering Contradiction:
Improvebrewing group managementVSAvoiddowntime and maintenance intervals
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The electronic control unit continuously monitors the operational status and wear levels of each brewing group, using this feedback information to dynamically balance the distribution of beverage production requests, thereby equalizing wear patterns and optimizing maintenance intervals

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system automatically manages brewing group load distribution and failure compensation without requiring manual intervention, with the electronic control unit self-adjusting task allocation based on real-time brewing group performance and availability

Inventive Principle:
Principle #25Self-service

AI summary

An electronic control unit (6) for a beverage vending machine (1) comprising at least two brewing groups (3) configured to carry out one and the same infusion process to produce one and the same beverage, e.g., coffee, from respective brewable substances either of the same type or of different types. The electronic control unit (6) is configured to control operation of the brewing groups (3) to cause the following beverage production modes to be selectively performable, each mode in response to a corresponding single user- selection: a first beverage production mode, in which the two brewing groups (3) are controlled to simultaneously produce the same quantity of said beverage from respective brewable substances of the same type; a second beverage production mode, in which the two brewing groups (3) are controlled to simultaneously produce the same quantity of said beverage from respective brewable substances of different types; a third beverage production mode, in which the two brewing groups (3) are controlled to simultaneously produce different quantities of said beverage from respective brewable substances either of the same type or of different types; and a fourth beverage production mode, in which the brewing groups (3) are controlled to simultaneously produce the same quantity of said beverage from respective brewable substances of the same type, but in a greater quantity than that produced in the first beverage production mode.
