Electronic Liquid Dosing Logs for Routine Validation and Traceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laboratory dosing systems inadequately track and validate work routines, leading to incomplete quality management and traceability of samples and liquids produced, making it difficult to ensure compliance and comparability between samples generated using identical routines.
Innovation Solution
An electronic laboratory dosing system that comprehensively records and logs operating data and context parameter data, allowing for real-time comparison with target specifications, and stores these as extended log data sets for retrospective validation and analysis, enabling improved quality management and comparability of samples and liquids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive data recording and comparison systems are implemented, then quality management and traceability are improved, but device complexity increases
Solution Approach 1:
The patent introduces a data processing system as an intermediary between the dosing device and the quality management processes. This intermediary handles the complex tasks of data recording, storage, and comparison with target specifications, allowing the dosing device itself to remain relatively simple while achieving comprehensive quality management through the mediating system that processes and validates the recorded data.
2Reliability
If comprehensive operating data and context parameter data are recorded and stored, then traceability of samples and liquids is improved, but loss of time for data processing increases
Solution Approach 1:
The system performs preliminary actions by automatically recording and storing both operating data and context parameter data during the dosing process itself, rather than requiring subsequent manual data collection. The data is immediately compared with target specifications and validation results are generated in real-time or near real-time, eliminating the need for time-consuming post-processing and enabling immediate traceability.
3Reliability
If automatic validation and comparison systems are implemented, then work routine validation is improved, but device complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where recorded operating data and context parameter data are automatically compared with pre-defined target specifications. The system provides feedback in the form of validation results that indicate whether work routines were executed correctly. This automated feedback loop improves work routine validation by continuously monitoring and comparing actual performance against targets, reducing the need for complex manual validation procedures.
