Axle Modulator With Separate Active Passive Sensor Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing axle modulators require different variants to handle active and passive speed sensors, leading to increased storage and planning costs due to the need for multiple types of control units and sensors, which complicates the production process.
Innovation Solution
An axle modulator with separate connections for active and passive speed sensors, allowing for the simultaneous connection and control of both types, with optional priority control and error handling, reducing the need for multiple units and variants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different variants of axle modulators are used for active and passive speed sensors, then the specific control requirements of each sensor type are met, but storage and planning costs increase and production complexity increases
Solution Approach 1:
The axle modulator is designed with multiple sensor connection interfaces that can accommodate both active and passive speed sensors. The control unit automatically detects the sensor type and adapts its operation accordingly, allowing a single modulator design to serve multiple sensor types without requiring separate variants for each sensor type.
Solution Approach 2:
The axle modulator incorporates dynamic sensor type detection and adaptation capabilities. The control unit can dynamically identify whether an active or passive sensor is connected and adjust its control strategy in real-time, enabling flexible operation with different sensor types rather than requiring fixed variant designs.

If different variants of axle modulators are used for active and passive speed sensors, then the specific control requirements of each sensor type are met, but production planning complexity increases
Solution Approach 1:
The axle modulator is designed with multiple sensor connection interfaces that can accommodate both active and passive speed sensors. The control unit automatically detects the sensor type and adapts its operation accordingly, allowing a single modulator design to serve multiple sensor types without requiring separate variants for each sensor type.
Solution Approach 2:
The axle modulator includes preliminary sensor type detection functionality that automatically identifies the connected sensor type during system initialization. This preliminary action eliminates the need for manual configuration or separate production planning for different sensor variants, as the system self-adapts to the connected sensors.
