Solution Overview

Problem

Existing methods for singularizing and separating vegetable products joined by stems, such as cherries, are inefficient, leading to incomplete separation and clogging of processing equipment, especially under heavy workloads and with unripe products, which complicates subsequent processing and measurement.

Innovation Solution

An apparatus with a V-shaped slot and motor-driven belts integrates cutting means, specifically rotating circular blades positioned to intercept and cut stems, combined with rising faces to facilitate stem interception and serrated edges for precise cutting, ensuring effective separation and singularization of vegetable products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If hydraulic acceleration and centrifugal separation are used to separate vegetable products, then separation efficiency is improved for loosely joined products, but heavy workloads and unripe products remain inadequately separated causing clogging

Engineering Contradiction:
Improveseparation efficiencyVSAvoidcomplete separation
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The apparatus divides the separation process into two distinct stages: first hydraulic acceleration to separate loosely joined products, then mechanical cutting for remaining joined products. This segmentation allows each stage to handle specific cases, ensuring complete separation even under heavy workloads with unripe products that resist initial hydraulic separation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hydraulic acceleration stage performs preliminary separation before the mechanical cutting stage. By first attempting to separate products through hydraulic forces, the system prepares the material stream so that only inadequately separated products (those still joined) require mechanical cutting, thus optimizing the overall separation process.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If mechanical cutting means are added to ensure complete separation, then separation completeness is improved, but device complexity increases

Engineering Contradiction:
Improvecomplete separationVSAvoidapparatus structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The apparatus merges hydraulic acceleration mechanisms with mechanical cutting means into a single integrated system. The cutting means are positioned within the same apparatus structure, allowing both separation stages to occur in one continuous process flow without requiring separate equipment, thus limiting the increase in device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The apparatus is designed to perform multiple functions: hydraulic acceleration for initial separation and mechanical cutting for final separation. This multi-functionality is achieved within a single apparatus structure, making the system more versatile while avoiding the need for multiple separate devices.

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

3Productivity

If products are processed in bunches without prior singularization, then processing speed is maintained, but measurement accuracy deteriorates due to uncertainty

Engineering Contradiction:
Improveprocessing speedVSAvoidcalibration accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The apparatus performs preliminary singularization through hydraulic acceleration and mechanical cutting before products enter the calibration zone. This preliminary action ensures that by the time measurement occurs, all products are individually separated, eliminating measurement uncertainty while maintaining continuous processing flow and speed.

Inventive Principle:
Principle #10Preliminary action
