Solution Overview

Problem

Existing cleaning devices for packaging systems are bulky, limited in reach, and require significant space within the production facility, making them inefficient and inflexible for cleaning hard-to-reach areas and requiring manual operation.

Innovation Solution

A mobile cleaning device equipped with a multi-axis robot and a control system that allows for fully automated cleaning, using mechanical, chemical, or radiation methods, and is designed to be decoupled from the production facility for maximum accessibility and space efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an integrated cleaning device is permanently installed within the packaging system, then cleaning coverage is limited to areas along guide rails, but the device requires a lot of space within the packaging system and impairs accessibility

Engineering Contradiction:
Improvecleaning coverageVSAvoidspace within packaging system
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The cleaning device is extracted from the packaging system and placed on a mobile base device that can move independently. This separation allows the cleaning device to access all areas of the packaging system without requiring permanent installation and guide rails, thereby saving space within the packaging system while maintaining comprehensive cleaning coverage

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The cleaning device transitions from a static, permanently installed position to a dynamic, mobile configuration. The mobile base device with multi-axis robot enables the cleaning head to dynamically position itself anywhere within the packaging system, providing both space efficiency and comprehensive cleaning capability

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If manual cleaning is performed by personnel, then flexibility in cleaning approach is maintained, but cleaning quality is highly dependent on personnel skills and cannot be reproduced

Engineering Contradiction:
Improvecleaning flexibilityVSAvoidcleaning quality consistency
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The cleaning device performs cleaning operations autonomously through automated control systems. The multi-axis robot executes pre-programmed cleaning paths and sequences, eliminating dependence on personnel skills while maintaining operational flexibility through programmable control, thereby ensuring consistent and reproducible cleaning quality

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The cleaning device incorporates sensors and control systems that provide feedback on cleaning progress and effectiveness. This automated feedback mechanism ensures consistent execution of cleaning tasks regardless of operator variability, while the programmable control maintains flexibility in adapting to different cleaning requirements

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If different cleaning tasks are assigned to personnel, then various cleaning requirements can be met, but cleaning planning becomes difficult due to varying time requirements

Engineering Contradiction:
Improvecleaning task varietyVSAvoidcleaning planning complexity
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The cleaning device uses programmable control to dynamically adjust cleaning parameters, paths, and sequences based on different cleaning tasks. This automation eliminates the need for manual time estimation and planning complexity, while maintaining versatility through software-configurable cleaning programs for various cleaning scenarios

Inventive Principle:
Principle #15Dynamics

4Reliability

If a cleaning device is laterally assigned to the packaging system, then cleaning function is provided, but accessibility to the packaging system is impaired

Engineering Contradiction:
Improvecleaning functionVSAvoidaccessibility to packaging system
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cleaning device transitions from a fixed lateral position to a mobile configuration that can enter and exit the packaging system as needed. The mobile base device allows the cleaning system to be positioned within the packaging system during cleaning operations and removed when not needed, maintaining both cleaning functionality and system accessibility

Inventive Principle:
Principle #15Dynamics
