Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If calibration is performed before use, then measurement accuracy is improved, but time consumption increases
Solution Approach 1:
The control unit is pre-trained during manufacturing with a computing model that enables it to perform measurements without requiring calibration in the clinical setting. This preliminary action during production eliminates the time-consuming calibration step while maintaining measurement accuracy across the entire measurement range.
2Reliability
If calibration is required for accurate measurement, then measurement reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The device performs self-calibration through its pre-trained control unit that autonomously adjusts and optimizes measurements without user intervention. The control unit independently applies the computing model to ensure accurate measurements across all parameters, making the device as easy to use as a standard non-calibrated device while maintaining reliability.
3Extent of automation
If a computing model is implemented in the control unit, then automation is improved, but device complexity increases
Solution Approach 1:
The computing model is developed and trained during manufacturing before the device is deployed clinically. This preliminary development phase allows complex algorithms to be established once, then the device can operate autonomously with this pre-established model, achieving high automation without requiring complex real-time adjustments or user configuration.

AI summary
The present invention refers to a device (1) and a method of measuring a parameter of blood, preferably correlated to the presence or concentration of oxygen in blood. The invention provides to: excite a photosensitive element (18') in contact with blood by excitation pulses, detect light responses of the photosensitive element corresponding to the excitation pulses, and analyze the plurality of luminescence decay curves at least two time windows (t1-tN). Moreover, the invention provides to: detect one or more light answer analog information regarding the luminescence curve decay at each time window, convert the analog information into digital data, process the digital data and the actual temperature value of blood by taking into account a plurality of data of previous measures of the parameter of blood performed during a previous training, and determine, as a result of the processing step, at least one value of said parameter of blood.
