Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the angle sensor and rotation counter are implemented in separate components, then reliability is improved and power consumption is reduced, but device complexity increases
Solution Approach 1:
The device is divided into separate functional components: an angle sensor for detecting rotation angles and a rotation counter for counting rotations. This segmentation allows each component to be optimized independently, improving reliability while enabling low power consumption operation of the rotation counter alone when the angle sensor is not in use.
Solution Approach 2:
The rotation counter function is extracted as a separate component from the angle sensor. This extraction enables the rotation counter to operate independently with lower power consumption and allows the system to meet safety requirements through functional redundancy without requiring the angle sensor to be continuously active.
2Use of energy by moving object
If the rotation counter operates independently with low power consumption, then energy efficiency is improved, but measurement precision may be compromised
Solution Approach 1:
The rotation counter is designed to perform its counting function independently without requiring continuous power from the angle sensor. It can detect and count rotations autonomously, maintaining measurement precision while consuming minimal energy, and can continue operation even when the vehicle battery is disconnected using its own power supply.
3Reliability
If a backup battery is implemented for power continuity, then reliability is improved, but device complexity and cost increase
Solution Approach 1:
A backup battery is implemented to provide power continuity for the rotation counter in advance of any power failure. This ensures that the rotation counter can maintain its counting function and store rotation data even when the vehicle battery is disconnected, meeting safety requirements without requiring complex power management systems.
