Solution Overview

Problem

The processing of reusable containers is inefficient and labor-intensive, as it often requires manual handling, inspection, and sorting, leading to high labor costs and resource wastage.

Innovation Solution

A system and method for automatically processing reusable containers, which includes a scanning module for identifying containers, a loading module for determining the container's state and loading or discarding it, a washing, rinsing, and drying module for processing the containers, and an unloading area for delivering processed containers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual processing of reusable containers is used, then labor flexibility is maintained, but processing efficiency is low and labor costs are high

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system enables containers to be automatically processed through self-identification using RFID tags or barcodes. Containers autonomously navigate through washing, rinsing, and drying stations without manual handling, significantly improving processing efficiency while reducing labor costs. The automatic identification and tracking system eliminates the need for manual sorting and monitoring.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical handling of containers is replaced by an automated control system that uses sensors, RFID readers, and conveyor mechanisms. The control unit coordinates various processing stations (washing, rinsing, drying) to handle containers automatically, substituting human labor with an integrated mechanical and control system that improves productivity.

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

2Loss of substance

If all containers are processed through washing, but some are defective, then resource waste occurs, but manual inspection is time-consuming

Engineering Contradiction:
Improveresource wasteVSAvoidinspection time
Core Design Contradiction:
Loss of substanceVSLoss of time

Solution Approach 1:

The system performs preliminary inspection of containers before they enter the washing process. Sensors detect defects such as cracks, excessive soil, or damage that would prevent proper cleaning. Containers identified as defective are automatically diverted or rejected before resource-intensive washing begins, preventing waste of water, energy, and time on unusable containers.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control unit continuously monitors container status throughout the processing line using sensors and RFID tracking. Based on feedback from inspection points, the system dynamically adjusts processing - diverting defective containers from the washing sequence and routing them to separate handling. This feedback mechanism ensures resources are only consumed by containers that can be successfully processed and reused.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If automatic processing system is implemented, then labor costs are reduced, but initial system complexity increases

Engineering Contradiction:
Improvelabor requirementVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The automated processing system is designed as a multi-functional integrated unit that combines washing, rinsing, drying, inspection, and container tracking in a single coherent system. The control unit manages multiple processing stations and container types through a unified interface, reducing the need for separate manual operations while maintaining operational simplicity through standardized procedures.

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