Solution Overview

Problem

Existing sorting devices for elongated articles, such as cigarettes, face challenges in efficiently separating low-quality or defective items from recyclable ones, leading to disordered and unsorted rejects that require manual pre-sorting and additional handling, with a significant portion of recyclable materials being wasted due to inefficient separation processes.

Innovation Solution

A sorting device with a sorting section that utilizes gravity to eject articles of insufficient length, featuring retaining elements like guide rails to hold longer articles and a cleated belt system with deflection rollers, ensuring efficient separation and further processing of recyclable components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing sorting devices are used to separate defective articles, then low-quality items can be removed, but the rejects become disordered and require manual pre-sorting, increasing handling complexity and time

Engineering Contradiction:
Improvequality separationVSAvoidhandling complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The sorting device segments the sorting line into multiple sorting sections, each dedicated to ejecting articles of a specific length range. This segmentation allows articles to be automatically sorted into different length categories as they pass through each section, eliminating the need for manual pre-sorting and reducing handling complexity while maintaining reliable quality separation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device performs preliminary sorting by length before the final quality inspection and sorting stages. By pre-separating articles into length categories in the first sorting section, the system prepares the articles for more efficient subsequent processing, reducing the complexity of later handling operations

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If all rejects are collected together without sorting, then collection is simple, but recyclable materials cannot be recovered and must be discarded, increasing material loss

Engineering Contradiction:
Improvecollection simplicityVSAvoidmaterial waste
Core Design Contradiction:
Ease of manufactureVSLoss of substance

Solution Approach 1:

The sorting line is divided into multiple sorting sections, each targeting a specific length range of articles. This segmentation enables automatic separation of recyclable articles (those meeting minimum length requirements) from non-recyclable rejects, allowing material recovery while maintaining simple collection processes for each category

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device implements a systematic approach to discarding and recovering materials by sorting articles into different length categories. Articles that meet minimum length requirements are retained for recovery and recycling, while only those below the threshold are discarded, maximizing material recovery while maintaining operational simplicity

Inventive Principle:
Principle #34Discarding and recovering

3Loss of substance

If manual pre-sorting is performed to separate recyclable rejects, then material recovery is improved, but handling time and labor requirements increase

Engineering Contradiction:
Improvematerial recoveryVSAvoidhandling time
Core Design Contradiction:
Loss of substanceVSLoss of time

Solution Approach 1:

The sorting device performs automatic sorting based on article length without requiring manual intervention. The retaining elements and gravity-based ejection mechanism enable the system to self-sort articles into appropriate categories, achieving material recovery while eliminating the time and labor costs associated with manual pre-sorting

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The device replaces manual mechanical sorting operations with an automated mechanical system using retaining elements and gravity-based ejection. This substitution maintains high material recovery rates while dramatically reducing handling time and eliminating labor requirements

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If a single sorting threshold is used, then the sorting device is simple to operate, but it cannot handle multiple quality criteria including different length requirements

Engineering Contradiction:
Improveoperational simplicityVSAvoidsorting criteria flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The sorting line is segmented into multiple sorting sections, each with its own retaining elements configured for a specific length threshold. This segmentation allows the system to handle multiple sorting criteria simultaneously while maintaining operational simplicity, as each section operates independently with a single threshold setting

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sorting device achieves multi-functionality by configuring different sorting sections with varying retaining element settings to handle multiple length criteria. This universal design allows a single device to sort articles according to multiple quality standards without complicating operation, as each section independently applies its specific threshold

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