Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-performance liquid chromatography (HPLC) systems face challenges in reliably testing fluidic configurations, leading to increased downtime and errors due to leakages, misconfigurations, and blockages, which are difficult to detect and diagnose, especially in complex setups and with limited user expertise.
Innovation Solution
A method involving applying a fluid with a specific characteristic to the fluidic system, measuring the output characteristic, and comparing it to a reference to detect and localize errors, allowing for efficient troubleshooting and maintenance without requiring extensive user expertise or custom testing for each configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual probing methods are used to troubleshoot fluidic systems, then diagnostic capability can be achieved, but troubleshooting time increases and system downtime is extended
Solution Approach 1:
The patent implements preliminary action by automatically executing diagnostic tests during idle periods or between analytical runs. The system proactively identifies fluidic system errors (leakages, blockages, misconfigurations) before they affect analytical operations, thereby reducing troubleshooting time and downtime while maintaining diagnostic capability.
Solution Approach 2:
The system performs self-diagnosis by automatically monitoring its own fluidic components without requiring manual intervention. The diagnostic system continuously assesses the health of pumps, valves, and fluid paths, enabling the system to self-identify and report issues, thus reducing both diagnostic capability loss and troubleshooting time.
2Reliability
If comprehensive testing of fluidic configurations is performed, then system reliability improves, but device complexity and testing requirements increase
Solution Approach 1:
The patent applies universality by designing a single, generic diagnostic system that can test multiple fluidic configurations and components through standardized procedures. The system uses a unified approach to detect leakages, blockages, and misconfigurations across different HPLC setups, thereby improving system reliability without proportionally increasing testing complexity.
Solution Approach 2:
The system manages complexity by dynamically adjusting testing parameters such as fluid flow rates, pressure levels, and test sequence configurations based on the specific analytical application and fluidic setup. This allows comprehensive reliability testing while adapting the complexity of the diagnostic procedure to match the actual system requirements.
3Productivity
If automated diagnostic systems are implemented, then troubleshooting efficiency increases, but initial system complexity and cost increase
Solution Approach 1:
The patent implements feedback mechanisms where the diagnostic system continuously monitors fluidic parameters and provides real-time information about system health. This automated feedback loop enables efficient troubleshooting by immediately identifying issues without manual intervention, thereby increasing productivity while managing system complexity through intelligent monitoring rather than complex hardware additions.
Solution Approach 2:
The system replaces manual mechanical troubleshooting with automated electronic monitoring and diagnostic algorithms. By substituting human operators with software-based diagnostic routines that analyze sensor data from fluidic components, the system achieves higher troubleshooting efficiency while actually reducing the need for complex mechanical diagnostic tools and manual testing equipment.
