Solution Overview
Problem
Existing forensic DNA analysis systems face challenges in timely data processing and expert review, leading to delays in identifying individuals of interest, particularly due to the lack of technical expertise at field locations and central command centers.
Innovation Solution
A command center system with network communications interfaces and user interfaces that allow for remote monitoring and control of forensic field test devices, including DNA analysis systems, enabling real-time data review, expert consultation, and management of consumables and equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If field equipment is deployed at various locations to collect and process DNA samples, then identification speed is improved, but technical expertise and problem-solving capability at field locations deteriorate
Solution Approach 1:
A command center acts as an intermediary between field equipment operators and central location experts. The command center receives help requests from field operators, relays them to experts at the central location, and communicates solutions back to the field. This mediator approach enables field deployment with rapid identification capability while compensating for the lack of technical expertise at distributed locations through centralized expert support.
2Productivity
If automated systems are used for DNA analysis, then processing speed is improved, but ability to perform expert review and quality control deteriorates
Solution Approach 1:
The system implements a feedback mechanism where automated DNA analysis systems at field locations upload results to a command center, which then routes files requiring review to experts. The feedback loop includes: automated processing generates initial results, quality control algorithms identify problematic files, experts review and correct flagged cases, and corrected results are uploaded to databases. This feedback structure maintains high processing speed for routine cases while ensuring reliability through expert review of problematic cases.
Solution Approach 2:
The system segments the DNA analysis workflow into automated processing tasks and expert review tasks. Automated systems handle high-volume routine processing to maintain speed, while expert reviewers focus only on flagged or problematic files requiring quality control. This segmentation allows the system to achieve both high productivity through automation and maintained reliability through targeted expert intervention.
3Extent of automation
If files requiring expert review are accumulated at command center, then centralized control is improved, but processing time and identification delay worsen
Solution Approach 1:
The system performs preliminary actions by implementing automated quality control algorithms that immediately flag problematic files as they are generated at field locations. This preliminary filtering prevents accumulation of unreviewed files at the command center by pre-identifying which files require expert review and which can be directly uploaded to databases. The preliminary action of automated screening reduces the backlog of files requiring centralized expert processing.
Solution Approach 2:
The system maintains continuous useful action through parallel processing: automated quality control algorithms continuously screen files as they are generated, experts continuously review flagged files, and corrected results are continuously uploaded to databases. This continuous parallel operation prevents file accumulation and minimizes delays, as the system processes files through multiple stages simultaneously rather than sequentially batching them at the command center.
Data Source
AI summary
A computer-implemented method for processing electropherograms provided through a communications network from one or more forensic field test devices to a central communications hub, wherein the forensic field test devices are configured to perform a biological assay analysis, the method implemented using one or more processors programmed with instruction to implement the method comprising receiving, at the central communications hub, one or more electropherograms transmitted through the communication network from the forensic field test devices; scoring each electropherogram based on one or more criteria; placing the one or more electropherograms in a queue for review; matching at least a subset of the electropherograms with each of one or more service providers; based on the matching, transmitting at least the subset to the one or more of the service providers for review; receiving reviewed electropherograms from the one or more service providers; and performing forensic analysis using the reviewed electropherograms.
