Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual medication preparation is performed without automated monitoring, then operational flexibility is maintained, but preparation accuracy and safety are compromised

Engineering Contradiction:
Improvemedication preparation accuracyVSAvoidmonitoring system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual visual inspection and physical measurement with automated image processing and computer vision algorithms. The system uses digital cameras to capture images of medication preparation processes and employs software algorithms to automatically verify dosages, identify medications, and detect preparation errors, thereby achieving high precision without requiring complex mechanical monitoring devices.

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

Solution Approach 2:

The patent creates a digital copy of the physical medication preparation process through image capture. Digital cameras continuously photograph the preparation area, and software algorithms process these images to create a virtual representation of the preparation state, enabling automated verification without physically interfering with the manual preparation process.

Inventive Principle:
Principle #26Copying

2Reliability

If comprehensive real-time monitoring is implemented, then preparation safety is improved, but processing time increases

Engineering Contradiction:
Improvepreparation safetyVSAvoidpreparation speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements continuous monitoring through digital cameras that operate throughout the entire medication preparation process. The system captures images continuously and processes them in real-time, ensuring that safety verification occurs at all critical stages without interrupting the workflow. The automated nature of the processing allows continuous safety checks to occur parallel to the preparation actions.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system performs self-verification by automatically analyzing images to check dosages, identify medications, and detect errors without requiring additional manual verification steps. The software algorithms independently verify preparation accuracy, eliminating the need for secondary manual checks that would slow down the process.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If digital surveillance and image processing are used for monitoring, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improvedosage verification accuracyVSAvoidsoftware system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs a multi-functional software system that performs multiple verification tasks using the same image processing infrastructure. The same digital cameras and processing algorithms used for dosage verification also identify medications, detect preparation errors, and document the process, eliminating the need for separate specialized devices for each function and reducing overall system complexity.

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

AI summary

The invention is a method and system for monitoring, documenting and assisting with the manual preparation and/or administration of medications. The invention accomplishes these goals via constant surveillance of the preparation/administration process using one or more digital cameras and software and hardware that processes the images and compares data from the processed images with information relative to the patient, to the drug components and composition of the medicament, and to non-drug items needed in the preparation that the system automatically or manually retrieves from various sources, e.g. internal or external data banks, from the technician/pharmacist, or by scanning the prescription.
