Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If indirectly determined values are used in tire monitoring systems, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The system uses feedback by continuously comparing indirectly determined tire parameters with directly measured parameters from tire-mounted sensors. The controller adjusts the indirect determination algorithms based on the difference between indirect and direct measurements, improving accuracy over time while maintaining system simplicity.
Solution Approach 2:
The system changes parameters by adjusting the indirect determination values based on direct measurements from sensors. When direct measurements are available, the system uses them to calibrate and refine the indirect parameter calculations, optimizing the balance between device complexity and measurement precision.
2Measurement precision
If direct measurement devices are added to improve accuracy, then measurement precision improves, but device complexity increases
Solution Approach 1:
The system applies universality by using existing tire-mounted sensors (pressure, temperature, acceleration) for multiple purposes. These sensors not only monitor their primary parameters but also provide data for adjusting and validating indirectly determined tire conditions, eliminating the need for additional dedicated sensors.
Solution Approach 2:
The system implements self-service by using the tire's own existing sensors to improve the accuracy of indirect measurements. The tire-mounted sensors provide direct measurements that are used to calibrate and refine the indirect determination algorithms, allowing the system to self-optimize without external intervention or additional hardware.
3Ease of operation
If indirect determination methods are used, then ease of operation is improved, but reliability deteriorates
Solution Approach 1:
The system applies preliminary action by pre-calculating and storing correction factors and calibration data based on direct measurements. These pre-computed adjustments are then applied to indirect determinations in real-time, ensuring reliable results without adding operational complexity.
