Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated sequencing systems are implemented, then productivity and throughput are improved, but device complexity increases
Solution Approach 1:
The sequencing system is divided into distinct functional modules: fluidics control/delivery system for reagent management, detection system for data acquisition, diagnostic components for parameter monitoring, quality evaluation circuitry for data assessment, and control circuitry for automated operation. This segmentation allows each module to be optimized independently while working together to achieve high-throughput automated sequencing.
2Reliability
If real-time monitoring and adaptive control are implemented, then reliability and data quality are improved, but device complexity increases
Solution Approach 1:
Diagnostic components continuously monitor system parameters such as temperature, reagent flow rates, and detection signals. Quality evaluation circuitry assesses sequencing data in real-time and provides feedback to control circuitry, which automatically adjusts operating conditions to maintain optimal performance and ensure data quality throughout the sequencing run.
Solution Approach 2:
The system performs preliminary quality assessment of sequencing data before final analysis. Quality evaluation circuitry identifies potential issues early in the sequencing process, allowing control circuitry to make corrective adjustments before problems affect the overall sequencing reliability.
3Measurement precision
If multiple diagnostic parameters are monitored, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The diagnostic components are designed to monitor multiple system parameters including temperature, reagent flow rates, detection signals, and other critical variables using integrated sensors and measurement devices. This multi-functional diagnostic approach enables comprehensive system monitoring without requiring separate dedicated systems for each parameter, thereby improving measurement precision while controlling overall device complexity.

AI summary
A technique for sequencing nucleic acids in an automated or semi-automated manner is disclosed. Sample arrays of a multitude of nucleic acid sites are processed in multiple cycles to add nucleotides to the material to be sequenced, detect the nucleotides added to sites, and to de-block the added nucleotides of blocking agents and tags used to identify the last added nucleotide. Multiple parameters of the system are monitored to enable diagnosis and correction of problems as they occur during sequencing of the samples. Quality control routines are run during sequencing to determine quality of samples, and quality of the data collected.
