Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic control systems for motor vehicles face challenges in unambiguously identifying actuators and preventing incorrect installation, especially with detachable connections, which limits the ability to replace components independently.
Innovation Solution
An electronic control system that includes a remotely mounted controller, an actuator, and a sensor board with actuator-specific data stored in its memory, allowing for unambiguous identification and transmission of this data to the controller via a common data line, enabling reliable component replacement and reducing the need for variant coding during production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If detachable connections are used between controller and actuator, then ease of replacement is improved, but reliability of identification is worsened
Solution Approach 1:
The patent introduces a sensor board as an intermediary component between the controller and actuator. This sensor board contains a memory element with actuator-specific data (serial number, variant information, calibration data). When the actuator is replaced, the sensor board automatically provides the controller with the new actuator's identification data, enabling reliable identification without requiring complex pairing procedures or preventing incorrect installations through hardware encoding.
2Measurement precision
If actuator-specific data is stored in the controller, then identification accuracy is improved, but device complexity is worsened
Solution Approach 1:
The patent segments the data storage function from the controller by placing actuator-specific identification data in a separate memory element on the sensor board. This segmentation allows the controller to remain simpler while still achieving accurate identification through data retrieval from the sensor board's memory, avoiding the need for complex data storage and management systems in the controller itself.
3Adaptability or versatility
If remotely mounted controller is used, then adaptability is improved, but loss of information is worsened
Solution Approach 1:
The patent implements preliminary action by pre-storing actuator-specific identification data (serial numbers, variant information, calibration data) in the memory element on the sensor board before the actuator is installed. This preliminary preparation ensures that when the remotely mounted controller needs to identify or configure an actuator, the necessary information is already available locally at the sensor board, eliminating information loss that would otherwise occur over long data transmission paths.
