Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual cleaning is used for evaporator surfaces, then operational simplicity is maintained, but hygiene and contamination prevention are insufficient

Engineering Contradiction:
Improvehygiene and contamination preventionVSAvoidcleaning system complexity
Core Design Contradiction:

Solution Approach 1:

The evaporator surface performs self-cleaning through its microstructured geometry that prevents adhesion of flavouring residues and facilitates automatic removal by gravity or rinsing, eliminating the need for manual intervention and ensuring consistent hygiene without adding complex cleaning mechanisms

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The evaporator surface geometry is modified at micro-scale with specific roughness parameters and patterning that change the surface properties to prevent adhesion of flavouring substances, allowing residues to be easily removed by gravity or simple rinsing rather than requiring complex cleaning systems

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If flavouring substances are dosed manually, then device complexity is reduced, but dosing precision and flavour consistency deteriorate

Engineering Contradiction:
Improveflavouring dosing precisionVSAvoiddosing system complexity
Core Design Contradiction:

Solution Approach 1:

The system pre-calculates and pre-configures the exact dosage of flavouring substances based on production parameters before the freezing cycle begins, ensuring precise and repeatable flavouring concentrations without requiring complex real-time adjustment mechanisms during operation

Inventive Principle:

AI summary

A system (10) and an apparatus (A1 - A4) for safely producing flavoured ice, where multiple flavourings (104) are dosed with precision and repeatability on single dosage lines (103, 105a - 105n, 106) and introduced into a mixing tank (107) together with water, with independent ducts, obtaining a flavoured mixture (108) which is then conducted to an evaporator with a protective and smoothing layer (102, 132). Automatic dosing means are provided which are connected to the central logic unit comprising a management algorithm (100, 133), with parameters which can be modified manually or automatically, like a self-adjustment, by means of multiple dosing means combined with each other, with adjusting members (109, 110, 113) combined with sensor means (116, 117, 118, 119, 120). Furthermore, the system (10) has automatic and integrated washing means, controlled by a washing algorithm (100, 134), for executing rinsing and/or washing with detergents.
