Solution Overview

Problem

Existing packaging machines for blister packs are inflexible, require significant space, and are prone to cross-contamination due to shared drug-carrying parts, limiting their use to centralized blister centers and necessitating manual patient-specific packaging.

Innovation Solution

A packaging machine that fills drugs directly into recesses, uses movable transport containers to avoid cross-contamination, incorporates a control unit for precise filling, and includes a cleaning station to ensure hygiene, with features like a conveyor belt, sealing, and exchangeable containers for flexibility and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing packaging machines use shared drug-carrying parts to fill multiple containers, then filling efficiency is improved, but cross-contamination occurs between different drugs

Engineering Contradiction:
Improvefilling efficiencyVSAvoidcross-contamination
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent divides the filling system into separate, dedicated filling stations for each drug type. Each station has its own container and filling mechanism, eliminating shared drug-carrying parts. This segmentation ensures that each drug is filled independently without risk of cross-contamination while maintaining efficient parallel operation across multiple stations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a transfer mechanism that acts as an intermediary between the filling station and the blister pack carrier. This transfer mechanism ensures that drugs are transferred directly from the source container to the target blister pack without contacting shared surfaces, thereby preventing cross-contamination while enabling continuous filling operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If prefabricated carriers with predetermined matrix of wells are used, then packaging standardization is improved, but flexibility for patient-specific packaging is lost

Engineering Contradiction:
Improvepackaging standardizationVSAvoidflexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent employs a dynamic carrier system where the blister pack carrier can be reconfigured or replaced based on patient-specific requirements. The carrier design allows for variable well arrangements, enabling the system to adapt between standardized matrices and customized configurations without compromising manufacturing efficiency or filling precision.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent designs a universal filling system that can accommodate multiple carrier types and configurations. The filling stations are equipped with adjustable mechanisms that can adapt to different well patterns, sizes, and arrangements, allowing the same equipment to produce both standardized and patient-specific packaging formats.

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

3Adaptability or versatility

If manual patient-specific packaging is performed, then flexibility is improved, but time consumption and labor costs increase

Engineering Contradiction:
ImproveflexibilityVSAvoidtime consumption
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements an automated system where the packaging machine itself performs the patient-specific customization. The control system automatically configures the filling process based on patient data, selecting appropriate drugs, dosages, and carrier arrangements without manual intervention. This self-service capability maintains flexibility while dramatically reducing time consumption and labor requirements.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent incorporates feedback mechanisms where the control system receives patient-specific requirements and automatically adjusts the filling process parameters. The system monitors the packaging process in real-time and makes automatic adjustments to ensure correct drug placement, dosage, and carrier configuration, eliminating the need for manual packaging while maintaining flexibility.

Inventive Principle:
Principle #23Feedback

4Productivity

If centralized blister centers are used for packaging, then equipment capability is improved, but space requirements and operational complexity increase

Engineering Contradiction:
Improveequipment capabilityVSAvoidspace requirements
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The patent divides the packaging system into compact, modular filling stations that can be distributed across different locations. Each station is self-contained and handles specific drug filling tasks, allowing the system to be deployed in space-constrained environments such as pharmacies or hospitals without requiring a large centralized facility. The modular design maintains high capability while reducing overall space requirements.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention relates to an individual blister packaging for drug administration, in particular a blister card, comprising a carrier, wherein the carrier has a plurality of recesses arranged in a matrix-like manner, and a cover film for closing the filled recesses, wherein at least two recesses are provided substantially independently from each other and, in particular, are connected to one another only by the cover film and/or a defined number of connection points.
