Engineering Contradiction Analysis
1Device complexity
If a single transmission path is used for communication between sensors and controller, then device complexity is reduced, but calculation of torque data from multiple sensor elements is delayed affecting real-time performance
Solution Approach 1:
The communication path is segmented into multiple independent channels, with each sensor element having its own dedicated communication path to the controller. This segmentation allows parallel data transmission from multiple sensors simultaneously, eliminating the sequential transmission bottleneck of a single path while maintaining manageable system complexity through modular architecture
2Speed
If multiple communication paths are used for concurrent data acquisition, then real-time performance is improved, but device complexity increases
Solution Approach 1:
The controller is designed with universal communication interface capabilities that can handle multiple communication paths simultaneously using a standardized protocol. Each communication path uses the same interface architecture, allowing the controller to process data from multiple sensors through a unified multi-functional framework, reducing complexity compared to implementing separate specialized interfaces for each path

AI summary
A sensor device includes multiple sensors, a controller, and multiple communication paths. Each of the sensors includes a sensor element and a sensor-side communication circuit. The sensor element detects a change in a physical quantity. The sensor-side communication circuit transmits a signal having a response signal according to a detected value of the sensor element, in response to a request signal transmitted by a controller. The controller includes a controller-side communication circuit and an arithmetic processing unit. The controller-side communication circuit transmits the request signal and receives the response signal. The arithmetic processing units calculates detection data according to the response signal. The communication paths respectively connect the sensors to the controller. The arithmetic processing unit calculates detection data by adopting respective response signals in parallel acquired from the sensors.
