Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sample analysis apparatus is integrated with the vial holder, then the analysis accuracy is improved, but the cleaning complexity increases and contamination risk arises
Solution Approach 1:
The apparatus is divided into separable components: the sample analysis apparatus (radiation system and analyser) and the holder with vial. This segmentation allows the vial to be easily removed and replaced, simplifying cleaning procedures while maintaining integrated analysis capability when the vial is in place.
Solution Approach 2:
The vial is extracted as a separate, removable component from the holder, allowing it to be taken out for cleaning or replacement without affecting the sample analysis apparatus. This extraction resolves the contamination risk and cleaning complexity while preserving measurement precision during analysis.
2Measurement precision
If the radiation intensity is increased to improve imaging quality, then the image clarity is improved, but the sample deterioration risk increases
Solution Approach 1:
The radiation intensity is made dynamically adjustable rather than fixed. The system can adapt the radiation intensity level based on the specific analysis requirements and sample sensitivity, allowing optimal balance between image clarity and sample protection for different measurement scenarios.
Solution Approach 2:
The radiation intensity parameter can be changed and optimized for different samples and analysis conditions. This parameter adjustment allows achieving sufficient image clarity while minimizing radiation exposure and preventing sample deterioration.
3Manufacturing precision
If the telecentric lens is used to maintain consistent image size, then the imaging consistency is improved, but the system complexity increases
Solution Approach 1:
A telecentric lens is introduced as an intermediary optical element between the sample and the analyser camera. This specialized lens ensures that rays entering the lens are parallel to the optical axis, producing consistent image size and magnification regardless of object position, thereby achieving imaging consistency while managing the added optical complexity.
4Ease of operation
If the vial is made removable from the holder, then the ease of cleaning is improved, but the alignment precision may deteriorate
Solution Approach 1:
The holder is designed with pre-defined alignment features and positioning mechanisms that automatically ensure correct alignment when the vial is placed in the holder. This preliminary preparation of alignment features eliminates the need for manual alignment adjustments, maintaining alignment precision while enabling easy removal and reattachment of the vial.
