Solution Overview

Problem

Existing wine processing installations often crush berries excessively during the winemaking process, negatively impacting the quality of wine in terms of organoleptic properties, and fail to effectively separate berries from stems and debris without harming the berries.

Innovation Solution

An installation comprising a scraper with a calibration device that sorts berries by size and shape, a destemmer, and a conveying system, which separates isolated berries before they enter the destemmer, reducing berry crushing and ensuring effective sorting and collection of berries without excessive trituration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional destemmer is used to separate berries from stems, then the separation function is achieved, but the berries are excessively crushed which harms wine quality

Engineering Contradiction:
Improveseparation functionVSAvoidberry crushing
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The processing system is segmented into multiple functional stages: calibration device for size-based separation, destemmer for stem removal, and collection system. This segmentation allows isolated berries to be separated before destemming, avoiding unnecessary crushing while maintaining effective stem separation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The calibration device performs preliminary separation of isolated berries before they enter the destemmer. By sorting berries by size and shape in advance, the system identifies and directs isolated berries to a gentler processing path, preventing premature crushing that would occur in traditional single-stage destemmers.

Inventive Principle:
Principle #10Preliminary action

2Object-affected harmful factors

If isolated berries are separated before destemming, then berry crushing is reduced, but the device complexity increases

Engineering Contradiction:
Improveberry crushingVSAvoidprocessing system
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The calibration device serves multiple functions: it calibrates berry size, separates isolated berries from clusters, and sorts products by caliber. This multi-functionality reduces the need for separate dedicated devices, thereby limiting the increase in overall system complexity while achieving berry protection.

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

Solution Approach 2:

The calibration device and destemmer are integrated into a unified processing line with shared conveying mechanisms and collection systems. By merging these functions into a coordinated system rather than separate standalone units, the patent reduces spatial complexity and operational overhead while maintaining the benefits of preliminary berry separation.

Inventive Principle:
Principle #5Merging (Combining)

3Object-affected harmful factors

If a calibration device is added upstream of the destemmer, then berry quality is improved, but the installation size increases

Engineering Contradiction:
Improveberry qualityVSAvoidinstallation size
Core Design Contradiction:
Object-affected harmful factorsVSArea of stationary object

Solution Approach 1:

The calibration device utilizes the vertical dimension by positioning it upstream and above the destemmer, with gravity-fed conveying between stages. This vertical arrangement optimizes space utilization and reduces the horizontal footprint of the installation while maintaining effective berry quality improvement through calibration-based separation.

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