Solution Overview

Problem

Existing beverage dispensing machines face limitations in their suction systems, which are not versatile enough to handle different types of soluble products, leading to inadequate suction flow that results in steam and dust cloud issues, such as clogging and waste, regardless of the beverage prepared.

Innovation Solution

A machine with a suction apparatus featuring a closure element that can be positioned in multiple settings to adjust the suction flow, allowing for optimal dust and steam removal regardless of the product type.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If the suction power is increased to improve dust and steam removal, then the suction flow increases, but soluble product is also suctioned into the mixing chamber causing waste and quality issues

Engineering Contradiction:
Improvedust and steam accumulationVSAvoidsoluble product waste
Core Design Contradiction:
Object-generated harmful factorsVSLoss of substance

Solution Approach 1:

The suction opening is made variable in size through a closure element that can be adjusted to different positions, allowing the suction apparatus to dynamically adapt its suction power to match the specific requirements of different soluble products and beverage types, thereby preventing both excessive suction of product and insufficient removal of dust and steam

Inventive Principle:
Principle #15Dynamics

2Object-generated harmful factors

If the suction opening size is increased to improve dust and steam aspiration, then the suction flow increases, but soluble product is also drawn into the mixing chamber

Engineering Contradiction:
Improvedust and steam cloud removalVSAvoidsuction flow suitability for different products
Core Design Contradiction:
Object-generated harmful factorsVSAdaptability or versatility

Solution Approach 1:

The closure element enables dynamic adjustment of the suction opening size, transforming a static suction apparatus into an adaptable system that can optimize its performance for different soluble products and beverage preparation requirements

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The size of the suction opening is changed as a variable parameter through the closure element, allowing the suction flow characteristics to be modified according to the specific needs of different products being processed

Inventive Principle:
Principle #35Parameter changes

3Object-generated harmful factors

If the suction fan power is increased to ensure adequate dust and steam removal, then the suction flow increases, but more soluble product is wasted due to excessive suction

Engineering Contradiction:
Improvesteam and dust outflowVSAvoidenergy wasted on suctioning soluble product
Core Design Contradiction:
Object-generated harmful factorsVSLoss of energy

Solution Approach 1:

Rather than increasing fan power, the invention dynamically adjusts the suction opening size to match the actual suction needs, thereby avoiding energy waste on unnecessary product suction while maintaining effective dust and steam removal

Inventive Principle:
Principle #15Dynamics

AI summary

A machine (1) for the automatic dispensing of beverages obtained from soluble products, such as milk, chocolate, tea, coffee, or the like, comprising: at least one mixing chamber (20), in which a soluble product is mixed with water; one or more ports (81) for feeding the soluble product, which are configured to convey the soluble product to the mixing chamber (20); at least one duct (33) for feeding water to the mixing chamber (20); a suction apparatus (5) configured to aspirate dust and/or steam from the mixing chamber (20); wherein the suction apparatus (5) comprises at least one suction port (60), which is in fluid communication with a flow generation device (51) configured to create a suction flow; the suction apparatus (5) comprises a closure element (40) which is associated with the suction port (60) and can be arranged selectively at least in: - a minimum-opening or closed position, in which it closes completely the suction port (60) or leaves free a minimum opening therein, - a maximum-opening position, in which it frees a maximum opening in the suction port (60), - at least one intermediate position, in which it closes the suction port (60) partially, leaving free in the suction port (60) an opening that is smaller than the maximum opening and larger than the minimum opening.
