Solution Overview

Problem

Existing machines for dispensing refrigerated fluid or pasty products face issues with ice and frozen product accumulation on the cooling element, which hinders thermal exchange and can damage the movement device due to excessive thickness.

Innovation Solution

A movement device with a helical element and scraper means that maintain the cooling element's surface free from ice and frozen product accumulation, ensuring efficient product flow and thermal exchange by using scraper edges and frontal blades to remove residues and enhance product pushing towards the dispensing faucet.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the cooling element operates continuously to cool the product, then the cooling efficiency is maintained, but ice and frozen product accumulate on the external surface of the cooling element, limiting thermal exchange and potentially damaging the movement device

Engineering Contradiction:
Improvecooling efficiencyVSAvoiddamage risk to movement device
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The scraper means are activated periodically to remove ice and frozen product accumulations from the cooling element surface before they can reach a thickness that would interfere with the movement device or transmission members. This preliminary cleaning action prevents the harmful effects of excessive accumulation while maintaining continuous cooling operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The movement device incorporates scraper means that automatically clean the cooling element surface during operation. The system serves itself by removing the harmful accumulations without requiring external intervention, thus preventing damage to the movement device while maintaining cooling efficiency.

Inventive Principle:
Principle #25Self-service

2Duration of action of stationary object

If ice and frozen product accumulate on the cooling element surface, then the cooling element continues to function, but thermal exchange between the cooling element and product is strongly limited

Engineering Contradiction:
Improvecontinuous operationVSAvoidthermal exchange efficiency
Core Design Contradiction:
Duration of action of stationary objectVSLoss of energy

Solution Approach 1:

The scraper means operate periodically during the continuous operation of the cooling element to remove ice and frozen product accumulations. This ensures that the thermal exchange surface remains clean and efficient throughout the operating cycle, preventing energy loss while maintaining continuous cooling function.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The scraper means are activated at periodic intervals to remove accumulations from the cooling element surface. This periodic cleaning action restores thermal exchange efficiency without requiring continuous interruption of the cooling operation, thus minimizing energy loss while maintaining continuous function.

Inventive Principle:
Principle #19Periodic action

3Productivity

If the helical element rotates to push the product towards the faucet, then the product flow is maintained, but excessive ice accumulation can interfere with the movement device and damage transmission members

Engineering Contradiction:
Improveproduct dispensing rateVSAvoidinterference with movement device
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The scraper means extract and remove the harmful ice and frozen product accumulations from the cooling element surface before they can interfere with the helical element's rotation or damage the transmission members. This separation of the harmful accumulation from the functional components protects the movement device while maintaining product dispensing productivity.

Inventive Principle:
Principle #2Taking out (Extraction)
