Engineering Contradiction Analysis
1Productivity
If blood samples are taken using a finger stick or tube, then the sampling process is simple and quick, but the measurement accuracy is distorted due to clotting and physical properties of capillaries
Solution Approach 1:
The patent applies parameter changes by measuring the temperature of the body part and using it as a correction parameter. The system gathers data including temperature measurements and uses this parameter to correct fluid sample measurements, accounting for temperature-induced variations in blood cell elasticity and stickiness that affect measurement accuracy.
Solution Approach 2:
The patent implements feedback by measuring temperature of the body part, comparing it to optimal temperature ranges, and using the temperature data to generate corrective factors that adjust the fluid sample measurements. This closed-loop approach continuously refines measurement accuracy based on real-time temperature conditions.
2Ease of operation
If blood samples are taken from capillaries, then the sampling is minimally invasive, but measurement accuracy is influenced by blood cell size, elasticity and stickiness
Solution Approach 1:
The patent changes the parameter being measured from just fluid content to include temperature of the body part. By measuring temperature and using it as a correction parameter, the system accounts for temperature-induced variations in blood cell physical properties such as elasticity and stickiness, thereby improving pathogen measurement accuracy while maintaining minimal invasiveness.
Solution Approach 2:
The patent introduces temperature measurement as an intermediary parameter that mediates between the physical state of blood cells and the final measurement. The temperature data serves as a mediator that helps correct for variations in blood cell properties, allowing accurate pathogen measurement despite the minimal invasive sampling method.
3Device complexity
If fluid samples are taken without temperature correction, then the measurement process is simple, but clotting distorts quantitative measurement and may damage the device
Solution Approach 1:
The patent applies preliminary action by measuring the temperature of the body part before taking the fluid sample. This preliminary temperature measurement allows the system to anticipate and correct for temperature-related effects on clotting and blood cell properties, improving measurement reliability without significantly increasing overall process complexity.
Solution Approach 2:
The patent implements beforehand cushioning by using temperature data to predict and prevent measurement distortions caused by clotting. The system prepares correction factors based on temperature measurements, cushioning against potential measurement errors and device damage before they occur.
