Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual verification methods are used for chemotherapy medication preparation, then flexibility and adaptability are maintained, but error rates increase and preparation efficiency decreases

Engineering Contradiction:

Improvepreparation accuracyVSAvoidpreparation efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent replaces manual visual inspection and physical verification with an automated image recognition system using cameras and computer vision algorithms. The system captures images of medication labels, barcodes, and preparation steps, then automatically verifies them against the prescription, eliminating the need for repeated manual checks while improving both accuracy and efficiency

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates digital copies of medication labels, barcodes, and preparation documentation through image capture. These digital copies are then processed by image recognition algorithms to verify medication identity, dosage, and preparation steps, replacing the need for physical manual verification while maintaining reliability

Inventive Principle:

Principle #26Copying

2Reliability

If repeated manual checks are performed to ensure medication safety, then verification reliability improves, but time consumption and labor requirements increase

Engineering Contradiction:

Improveverification reliabilityVSAvoidpreparation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The image recognition system operates continuously throughout the medication preparation process, automatically verifying each step as it occurs rather than requiring intermittent manual checks. The system maintains continuous monitoring of the preparation process, capturing images and verifying compliance in real-time, which eliminates time loss associated with stopping for manual verification

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The system performs preliminary verification by capturing and analyzing images of medication labels, barcodes, and preparation instructions before the actual medication preparation begins. This preliminary image recognition and verification process ensures that all parameters are correct before any physical manipulation of medications occurs, preventing errors early in the process

Inventive Principle:

Principle #10Preliminary action

3Object-affected harmful factors

If complex verification procedures are implemented to handle cytotoxic drugs safely, then medication safety improves, but operational complexity increases

Engineering Contradiction:

Improvedrug safetyVSAvoidverification system complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent implements a universal image recognition system that can verify multiple aspects of medication safety through a single integrated platform. The system handles barcode recognition, label verification, dosage confirmation, and preparation step validation all through one unified image capture and processing system, reducing operational complexity despite the comprehensive safety checks required for cytotoxic drugs

Inventive Principle:

Principle #6Universality (Multi-functionality)
