Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only one single cassette is operated at a given time, then the device complexity is reduced and operation is simplified, but the productivity decreases and inspection time increases
Solution Approach 1:
The system divides the inspection task into multiple independent cassettes, each containing specific specimens. Multiple cassettes are arranged on a rotating tray, allowing parallel inspection of different specimens simultaneously. This segmentation enables the system to process multiple specimens in one operational cycle, significantly improving productivity without requiring entirely separate inspection systems.
Solution Approach 2:
The patent combines multiple cassettes and inspection functions into a single integrated centrifugal analysis system. The rotating tray merges multiple specimen containers, while the optical sensor device and centrifugal mechanism are consolidated into one system that handles all cassettes uniformly. This merging allows simultaneous operation of multiple cassettes while maintaining manageable system complexity through unified control.
2Loss of time
If multiple cassettes are operated simultaneously, then the productivity increases and inspection time decreases, but the device complexity increases and positioning accuracy requirements increase
Solution Approach 1:
Position detection marks are introduced as intermediary elements between the cassettes and the optical sensor device. These marks serve as reference points that facilitate accurate positioning and identification of each cassette's location on the rotating tray. The detection marks enable the optical sensor to precisely identify and inspect specific specimens without requiring complex positioning mechanisms, thus maintaining measurement precision while enabling multi-cassette operation.
Solution Approach 2:
The system replaces complex mechanical positioning mechanisms with an optical detection system. Instead of using precise mechanical stops or alignment features, the patent employs optical sensors to detect position detection marks and identify cassette locations. This substitution simplifies the mechanical structure while achieving the required positioning accuracy through non-contact optical measurement, reducing mechanical complexity while maintaining precision.
3Productivity
If multiple cassettes are operated simultaneously, then the productivity increases, but the ease of operation decreases and operational complexity increases
Solution Approach 1:
The rotating tray and optical sensor device are designed with universal functionality to handle multiple cassettes of the same type. The system can inspect various specimens using the same operational procedure and detection mechanism, regardless of which cassette is being inspected. This universality allows operators to load multiple cassettes and run inspections simultaneously without requiring different operations for each cassette, maintaining ease of operation while improving productivity.
Solution Approach 2:
The system employs periodic rotation of the tray to bring different cassettes into the inspection position sequentially. This periodic action allows the optical sensor to systematically inspect each cassette in turn during a single operational cycle. The regular, repeating motion simplifies control and operation, as the system follows a predictable sequence that automatically manages multiple cassettes without requiring complex intervention, thereby maintaining operational simplicity while achieving high productivity.
