Solution Overview

Problem

The high costs and complexities associated with maintaining and operating clean rooms for packaging pharmaceutical, chemical, and biocidal products, including the need for large spaces and frequent shutdowns due to machine malfunctions, which lead to contamination and production losses.

Innovation Solution

A packaging system where the cutting unit is located outside the clean room, allowing for reduced clean room dimensions, simplified maintenance, and preservation of production queues during malfunctions, with a separate room for the forming station and controlled atmosphere management to minimize contamination risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If all packaging operations are performed inside the clean room, then product contamination is prevented, but clean room dimensions and maintenance costs increase

Engineering Contradiction:
Improveproduct contamination preventionVSAvoidclean room dimensions and maintenance complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The packaging system is divided into two distinct segments: operations inside the clean room (forming station, assembly, closing) and operations outside the clean room (cutting unit). This segmentation allows the clean room to be smaller while maintaining product protection, as only the most critical contamination-sensitive operations are performed within the controlled environment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cutting unit is extracted from the clean room and placed outside it. This extraction reduces the clean room footprint and simplifies maintenance operations, while the sheet is transferred through a controlled interface that prevents contamination. The cutting operation, being less sensitive to contamination, is performed in a standard environment.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If the cutting unit is located inside the clean room, then product protection is maintained, but maintenance operations become complex and costly

Engineering Contradiction:
Improveproduct protectionVSAvoidmaintenance operation simplicity
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The cutting unit is extracted from the clean room environment and positioned outside it. This allows maintenance personnel to perform repairs and maintenance operations in a standard, non-controlled environment, eliminating the need for atmospheric remediation and simplifying access to maintenance components. Product protection is maintained through the controlled transfer interface for the sheet.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of manufacture

If the clean room is large to accommodate all equipment, then all operations can be performed in one location, but installation and maintenance costs increase

Engineering Contradiction:
Improveoperation integrationVSAvoidinstallation and maintenance costs
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The packaging system is segmented into clean room and non-clean room zones, with the sheet serving as the transfer medium. This spatial segmentation allows each zone to be optimized independently: the clean room contains only the necessary equipment for contamination-sensitive operations, while the cutting unit operates in a standard environment, reducing overall installation and maintenance costs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sheet acts as an intermediary carrier that transfers the packaged products from the clean room forming station to the external cutting unit. This intermediary mechanism enables the separation of operations across different environmental zones while maintaining product integrity and process continuity.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Device complexity

If the clean room is minimized in size, then costs are reduced, but machine malfunctions may require entering the clean room for maintenance

Engineering Contradiction:
Improveclean room sizeVSAvoidmaintenance access
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

The cutting unit is extracted from the clean room and positioned outside it, allowing maintenance personnel to access and service this component in a standard environment without entering the clean room. This extraction eliminates the need for atmospheric remediation and simplifies maintenance access while maintaining a compact clean room size for the critical forming operations.

Inventive Principle:
Principle #2Taking out (Extraction)
