Actuating Device Sensor Segmentation for Transmission Defect Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional actuating devices in vehicles lack direct feedback on the actual actuator position, failing to detect mechanical defects such as ruptures in the transmission device, which can lead to mechanical failures.
Innovation Solution
An actuating device with a separated signal receiver and transducer, where the transducer is part of the transmission device, allowing for direct detection of actuator position and movement differences, enabling detection of defects in both the actuating drive and transmission device without impeding the actuating drive's function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional sensor device is used to record actuating position feedback, then the actuating drive can be controlled, but mechanical defects in the transmission device cannot be detected
Solution Approach 1:
The sensor device is segmented into two separate components: a signal receiver integrated into the actuating drive and a transducer integrated into the transmission device. This segmentation allows the transducer to directly detect actuator position while the signal receiver processes the signal, enabling defect detection in the transmission device without losing position information.
Solution Approach 2:
A magnetic coupling intermediary is introduced between the signal receiver and transducer, allowing indirect signal transmission through the transmission device. This enables the transducer to detect actuator position directly while the signal receiver remains in the actuating drive, facilitating defect detection while preserving position feedback.
2Device complexity
If the sensor device is integrated into the actuating drive, then the structure is compact, but defects in the transmission device remain undetected
Solution Approach 1:
The sensor device is divided into two parts: the signal receiver stays in the actuating drive maintaining compact integration, while the transducer is placed in the transmission device to enable direct actuator position detection and transmission defect monitoring.
Solution Approach 2:
Magnetic coupling serves as an intermediary mechanism that allows the transducer in the transmission device to communicate with the signal receiver in the actuating drive, enabling distributed sensing without complex wiring or mechanical connections.
3Measurement precision
If the transducer is separated from the actuating drive and placed in the transmission device, then direct actuator position detection is enabled, but the signal transmission complexity increases
Solution Approach 1:
The mechanical or electrical signal transmission system is replaced with a magnetic coupling system. The transducer in the transmission device generates magnetic signals that are received by the signal receiver in the actuating drive, enabling precise actuator position measurement without complex mechanical linkages or electrical wiring through the transmission device.
