Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple cuvettes are used on test cards to hold samples, then the testing capacity is improved, but the instrument cost increases
Solution Approach 1:
A single rotating optics assembly serves multiple cuvettes by providing light at different frequencies to different positions. The same physical optics component performs the function of what would traditionally require separate light sources for each cuvette, reducing instrument cost while maintaining multi-sample testing capacity.
Solution Approach 2:
The optics assembly is made rotatable to dynamically change which cuvette receives light at which frequency. This dynamic reconfiguration allows one set of optics to serve multiple static cuvettes, improving productivity without proportionally increasing device complexity or cost.
2Adaptability or versatility
If multiple light sources are used to provide different frequencies to multiple cuvettes, then the testing versatility is improved, but the device complexity increases
Solution Approach 1:
The rotating optics assembly provides multiple light frequencies from a single physical location to multiple cuvettes. This universal component replaces what would traditionally require multiple separate light sources, achieving testing versatility without proportional increases in device complexity.
Solution Approach 2:
Multiple light-emitting diodes are combined into a single rotating assembly that serves multiple cuvettes. By merging what would be separate light sources into one integrated rotating unit, the system achieves versatile multi-frequency testing capability while reducing overall device complexity.
3Measurement precision
If fixed optics are used for each cuvette, then the alignment precision is improved, but the device complexity increases
Solution Approach 1:
The optics assembly rotates to dynamically align with different cuvettes, providing precise alignment through controlled rotation rather than through multiple fixed alignment mechanisms. This dynamic approach achieves the necessary alignment precision while reducing device complexity.
