Optical Code Batch Validation for Medical Sample Traceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sample tracing systems in medical laboratories are inefficient due to the need for manual, individual processing of optical codes, leading to productivity bottlenecks and errors when handling large batches of samples, as existing devices can only read one code at a time and lack the ability to validate batches or display information instantaneously.
Innovation Solution
A device and method that allows for simultaneous reading and validation of multiple one-dimensional or two-dimensional optical codes using a digital camera and image-processing system, enabling batch processing and displaying information on a user interface, which includes a sample tracing database manager to manage and display the status of multiple codes and images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If individual laser readers are used to read optical codes, then code reading accuracy is maintained, but productivity decreases significantly when handling large batches of samples
Solution Approach 1:
The patent combines multiple code reading operations into a single batch processing step. Instead of using individual laser readers to read codes one by one, the system captures images of multiple samples simultaneously and processes all codes in parallel through image recognition algorithms, achieving batch processing while maintaining reading accuracy
Solution Approach 2:
The patent replaces the mechanical laser reading system with an optical imaging system. Instead of using laser devices that read codes sequentially, the system uses digital cameras to capture images of multiple codes simultaneously and employs software-based image processing to recognize and read all codes in parallel, eliminating the sequential mechanical reading process
2Reliability
If manual individual code reading is performed, then system complexity remains low, but error detection and validation capability is insufficient
Solution Approach 1:
The patent implements a feedback mechanism where the system captures images of samples, processes the codes through image recognition, validates the read codes against expected formats and databases, and provides immediate feedback on validation results. This automated feedback loop significantly improves error detection capability compared to manual reading
Solution Approach 2:
The patent performs preliminary image capture and code recognition before final validation. By pre-processing the code images and extracting code information in advance, the system can validate multiple codes simultaneously and identify errors before they propagate through the workflow, enhancing reliability without proportionally increasing complexity
3Productivity
If batch processing is implemented, then productivity increases, but the ability to display and verify information instantaneously is limited
Solution Approach 1:
The patent maintains continuous information flow during batch processing. While multiple codes are being processed in parallel, the system continuously updates the user interface with validation results as they become available, ensuring that information is displayed in real-time without interrupting the batch processing workflow. This allows operators to monitor and verify information instantaneously while maintaining high productivity
