Solution Overview

Problem

Existing sample container sorting devices require manual sorting based on visual distinctions and take too long due to individual handling of containers, necessitating automation for faster processing.

Innovation Solution

A sample container sorting device with a container holding/lifting unit, transport unit, and identification unit that collectively identifies and sorts multiple containers by attributes, using a control unit to manage the sorting process efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual sorting based on visual distinction is used, then sorting accuracy is maintained, but processing time becomes excessively long

Engineering Contradiction:
Improveprocessing speedVSAvoidsorting time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces manual visual inspection and mechanical handling with an automated identification system using barcode scanners or optical recognition devices. The control unit automatically reads container attributes and controls the lifting mechanism to sort containers without human intervention, significantly reducing sorting time while maintaining accuracy through digital identification rather than visual estimation.

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

Solution Approach 2:

The system enables self-service sorting where containers are automatically identified and sorted based on their own attributes (barcode, color, shape). The control unit processes identification information and autonomously controls the lifting mechanism to place containers in correct positions, eliminating the need for manual sorting operations and reducing processing time.

Inventive Principle:
Principle #25Self-service

2Productivity

If individual handling of containers is performed, then sorting precision is maintained, but processing efficiency decreases

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidsorting precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent merges multiple container handling operations into a single automated process. The control unit simultaneously manages identification, attribute reading, and positioning for multiple containers through one coordinated lifting mechanism operation, rather than handling each container separately. This integrated approach improves efficiency while maintaining precision through automated control.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system incorporates feedback mechanisms where the control unit continuously monitors container identification results and adjusts the lifting mechanism accordingly. After identifying container attributes through barcode scanning or optical recognition, the control unit receives feedback information and automatically positions containers with precise control, ensuring both high efficiency and accurate sorting.

Inventive Principle:
Principle #23Feedback

3Productivity

If automated identification is implemented, then processing speed increases, but device complexity increases

Engineering Contradiction:
Improvesorting speedVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The control unit is designed as a multi-functional device that integrates identification processing, attribute reading, sorting decision-making, and mechanism control into a single system component. This universal approach increases sorting speed through automation while minimizing the number of separate devices needed, thereby limiting the increase in overall system complexity.

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