Engineering Contradiction Analysis
1Productivity
If the angle sensor senses rotation first and then the distance sensor measures distance sequentially, then the sensing process is simple to implement, but the ranging time cannot be utilized efficiently and computing efficiency is affected
Solution Approach 1:
The patent merges the angle sensing and distance sensing operations into a concurrent process. The angle sensor and distance sensor operate simultaneously during the ranging time, with the angle sensor continuously providing angle information while the distance sensor measures distance. This combination eliminates the sequential execution bottleneck and maximizes the utilization of ranging time for both sensing operations.
2Productivity
If angle and distance information are acquired sequentially in separate steps, then the sensing process is straightforward, but the operating efficiency of the ranging device is reduced
Solution Approach 1:
The patent implements continuous angle sensing throughout the ranging process while distance measurement occurs concurrently. The angle sensor operates continuously without interruption, providing a stream of angle information that correlates with the distance measurement timeline. This continuous operation eliminates idle periods and maintains maximum operational efficiency throughout the ranging cycle.
3Measurement precision
If the ranging device waits for angle information before starting distance sensing, then the angle and distance data are synchronized, but the overall sensing time increases
Solution Approach 1:
The patent prepares angle information in advance by having the angle sensor continuously acquire and buffer angle data before, during, and after distance measurement. This preliminary preparation ensures that when distance measurement is performed, the corresponding angle information is already available and synchronized, eliminating the need to wait for angle sensing to complete before starting distance sensing.
