Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual handling of packages and blister carriers is used on conveyor routes, then device complexity is reduced, but productivity and safety are worsened

Engineering Contradiction:
ImprovesafetyVSAvoidautomation level
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system enables self-service through automated identification and routing. Packages and blister carriers are automatically scanned, identified, and directed to appropriate destinations without manual intervention. The conveyor system autonomously manages the flow of materials between workstations, storage areas, and packaging stations, eliminating the need for manual handling while maintaining operational safety.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical handling is replaced with an automated conveyor system. The patent implements automated transport mechanisms that move packages, blister carriers, and pill containers between different stations. This substitution of manual labor with automated mechanical systems improves safety by eliminating human exposure to potential hazards while enhancing productivity.

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

2Productivity

If multiple medication types are processed simultaneously, then productivity increases, but device complexity and planning effort increase

Engineering Contradiction:
Improverepackaging throughputVSAvoidlogistics management
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The repackaging device is designed with universal functionality to handle multiple medication types simultaneously. The system incorporates multiple workstations, storage areas, and conveyor paths that can process different medications through the same automated framework. The identification and routing system universally applies to all medication types, allowing parallel processing without requiring separate dedicated systems for each medication.

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

Solution Approach 2:

The system segments the repackaging process into distinct functional zones: identification stations, routing decisions, conveyor transport paths, workstations for repackaging, and storage areas. Each medication type can be routed through appropriate segments independently. This segmentation allows simultaneous processing of multiple medications while maintaining organized logistics management through modular process control.

Inventive Principle:
Principle #1Segmentation

3Productivity

If automated conveyor systems with multiple paths are implemented, then productivity and flexibility improve, but device complexity increases

Engineering Contradiction:
Improverepackaging speedVSAvoidconveyor system structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The conveyor system incorporates dynamic routing capabilities where transport paths can be actively directed based on real-time requirements. The system can dynamically assign different paths for packages, blister carriers, and pill containers depending on their destination and processing stage. This dynamic control enables efficient multi-path operation without requiring permanently complex fixed infrastructure, as routing can be adjusted through control systems rather than physical reconfiguration.

Inventive Principle:
Principle #15Dynamics
