Solution Overview

Problem

Existing pasta cutting machines suffer from ventilation systems that are not optimally effective across different pasta types, affecting pasta drop-conveying and microclimate conditions in the collection chamber and chute.

Innovation Solution

A dual ventilation system with independent control of air flow parameters for the collection chamber and conveyor chute, utilizing separate fans and air-conditioning systems to optimize air flow conditions based on pasta characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single ventilation system is used for both the collection chamber and conveyor chute, then the device complexity is reduced, but the adaptability to different pasta types and the optimization of air flow conditions deteriorate

Engineering Contradiction:

Improveventilation system structureVSAvoidadaptation to pasta characteristics

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The ventilation system is divided into two independent units: a first ventilation unit for the collection chamber and a second ventilation unit for the conveyor chute. Each unit can be controlled separately with different air flow rates, temperatures, and moisture levels, allowing optimization for different pasta types without increasing overall system complexity significantly.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The ventilation system incorporates dynamic control capabilities where air flow parameters (rate, temperature, moisture) can be adjusted independently for each ventilation unit based on the specific pasta characteristics being processed, enabling adaptability across different pasta types.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If air flow parameters are standardized for both collection chamber and chute, then the ease of operation is improved, but the manufacturing precision of pasta drop-conveying deteriorates

Engineering Contradiction:

Improveventilation controlVSAvoidpasta drop-conveying optimization

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

Different air flow parameters are applied to different locations: the first ventilation unit provides optimized air flow for the collection chamber while the second ventilation unit provides different optimized parameters for the conveyor chute. This local differentiation ensures precise control of pasta drop-conveying while maintaining ease of operation through automated control.

Inventive Principle:

Principle #3Local quality

3Device complexity

If a single air conditioning system is used for both ventilation units, then the device complexity is reduced, but the ability to independently control temperature and moisture for different sections deteriorates

Engineering Contradiction:

Improveair conditioning systemVSAvoidindependent parameter control

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The air conditioning capability is segmented into two independent systems: a first air conditioning system for the first ventilation unit and a second air conditioning system for the second ventilation unit. This allows independent control of temperature and moisture for each section, optimizing pasta handling in both the collection chamber and conveyor chute.

AI summary

The cutting machine (1) comprises a cutting unit (15) and a chamber (13) for collecting pasta cut by the cutting unit (15). Arranged beneath the collection chamber is a conveyor chute (31) adapted to receive the pasta exiting from the collection chamber (13). A first ventilation unit (40) and a first channel (37, 38) are adapted to convey a first air flow to the collection chamber (13) through openings (35A) of the side wall (35) of the collection chamber. A second ventilation unit (50) and a second channel (55) are adapted to convey a second air flow to the conveyor chute (31) and to form an air cushion along the drop surface of the chute.
