Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation by service engineer is used to check optical performance, then optical performance can be checked, but the process is inefficient and requires special work
Solution Approach 1:
The capillary electrophoresis device performs self-diagnosis of its optical system by automatically capturing images with the detection unit, extracting absolute values from the images, and comparing them with reference values to determine optical performance, eliminating the need for manual service engineer intervention
Solution Approach 2:
The patent replaces manual mechanical inspection with an automated optical measurement system that uses the detection unit to capture images and the control unit to automatically process and analyze the optical performance data
2Measurement precision
If relative index is used for optical performance measurement, then measurement can be performed, but accuracy is reduced
Solution Approach 1:
The patent changes the measurement parameter from relative index to absolute value, where the control unit extracts absolute values directly from images captured by the detection unit and compares them with reference absolute values, thereby improving measurement accuracy and reliability
3Productivity
If automated diagnosis is implemented, then operational efficiency is improved, but device complexity increases
Solution Approach 1:
The control unit and detection unit are designed to serve multiple functions: they are used both for normal capillary electrophoresis operation and for automated optical performance diagnosis, eliminating the need for separate dedicated diagnostic hardware and reducing overall system complexity
