Solution Overview

Problem

The surface pattern of fresh pasta sheets formed by existing machines results in micro-channels that cause a significant portion of sauce to drain off instead of being retained, making it unsuitable for dressing.

Innovation Solution

A dough sheeter machine with a sheeter roller featuring multiple intersecting cylindrical helical slots that create an irregularly rough surface pattern, combining first and second patterns of slots with different arrangements to enhance sauce retention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a continuous and regular surface pattern of linear slots is used on the sheeter roller, then the pasta sheet surface is formed with uniform micro-channels, but the sauce drains off instead of being retained

Engineering Contradiction:
Improveuniformity of surface patternVSAvoidsauce retention capability
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent applies asymmetry by introducing a second pattern of linear slots with different orientation and/or pitch compared to the first pattern. This creates an irregular surface pattern where the alternating troughs and crests are not uniformly aligned, preventing sauce from draining along continuous channels while maintaining manufacturing precision through the systematic formation of multiple slot patterns

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The patent adds another dimension to the surface pattern by incorporating slots at different orientations or pitches. Instead of a single-plane regular pattern, the second pattern introduces variability in the slot arrangement, creating a three-dimensional surface topology that enhances sauce retention while preserving the structured formation process

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If multiple intersecting cylindrical helical slots are used on the sheeter roller, then the surface pattern becomes irregularly rough to retain sauce, but the device complexity increases

Engineering Contradiction:
Improvesauce retention capabilityVSAvoidroller structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple cylindrical helical slots onto a single sheeter roller, combining the first pattern with the second pattern. This integration creates an irregularly rough surface that retains sauce effectively while avoiding the need for separate processing stages or multiple rollers, thus managing device complexity through consolidation

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sheeter roller is designed with multi-functionality by incorporating both the first and second patterns of linear slots on a single component. This universal roller performs both the sheeting and the creation of the irregular surface pattern in one operation, reducing overall device complexity despite the increased structural detail of the roller itself

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