Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual verification is performed by pharmacy attendants, then medication content can be visually inspected against prescription, but the process is time-consuming and prone to human error
Solution Approach 1:
The patent replaces the manual mechanical verification process with an automated optical imaging and image processing system. The system uses digital images captured by cameras and processed by computer algorithms to automatically verify medication content, eliminating the need for manual visual inspection by pharmacy personnel.
Solution Approach 2:
The system creates digital copies (images) of the medication package contents and compares these copies against the prescription data. This allows for rapid automated verification without physical handling or manual inspection of the actual medication items.
2Reliability
If manual verification is performed, then medication packages can be inspected, but human error may lead to incorrect medication being dispensed
Solution Approach 1:
The patent replaces the manual mechanical verification process with an automated optical imaging and image processing system. The system uses digital images captured by cameras and processed by computer algorithms to automatically verify medication content, eliminating the need for manual visual inspection by pharmacy personnel.
Solution Approach 2:
The system provides automated feedback by comparing the imaged medication content against the prescription requirements and alerting to any discrepancies. This closed-loop verification process ensures that errors are detected and prevented before incorrect medication reaches the patient.
3Measurement precision
If multiple light sources are used to image medication items, then detailed verification of medication characteristics is possible, but device complexity increases
Solution Approach 1:
The patent segments the imaging function into multiple specialized light sources, each designed to highlight specific medication characteristics. Different light sources illuminate different aspects of the medication items (such as color, shape, surface features), allowing the system to capture comprehensive verification data through coordinated use of these segmented imaging functions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system significantly reduces the risk of human error by accurately and efficiently verifying medication contents, ensuring correct dosages and types are dispensed, thereby enhancing patient safety and reducing the time required for verification processes.
Implementation Method 1
a light source to emit light on the medication item
Data Source
AI summary
A system for verifying medication doses in a filled medication package comprises a camera(s), a contour light source(s), a set of relief light sources. A verification unit may be used for imaging a contour of the medication items, imaging a surface relief of the medication items, processing the images, confirming the content of the medication package relative to identification of a type of medication item and/or medication package using the processing of the images. An interface produces a verification output based on the confirmation by the verification unit.
