Trailer Braking Controller Data Assignment via RFID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for storing vehicle-specific data in commercial vehicle trailers are prone to errors during manufacturing, commissioning, or repair due to the complexity of selecting appropriate parameter data sets, especially when numerous options are available.
Innovation Solution
An information medium, such as a sticker or metal plate, is attached to the trailer to reliably assign vehicle-specific data, which can be read using a barcode or RFID reader, allowing accurate data transmission to the electronic control unit's parameter memory, thereby reducing the risk of incorrect data selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple parameter data records are stored on a computer for manual selection, then the system can accommodate different trailer configurations, but the risk of selecting incorrect data increases due to human error
Solution Approach 1:
The control unit automatically reads the identification data (barcode, RFID, or data carrier) from the trailer and autonomously selects and stores the corresponding parameter data record, eliminating manual selection and human error entirely
Solution Approach 2:
The manual mechanical process of selecting parameter data records is replaced by an automated electronic reading system that scans identification data and automatically retrieves the correct parameters from storage
2Reliability
If an information medium is permanently attached to the trailer with secure fastening, then the reliability of data assignment is improved, but the device complexity and manufacturing effort increase
Solution Approach 1:
The system accepts multiple types of information media (stickers, metal plates, data carriers) and multiple attachment methods (adhesive, rivets, welding, clipping), allowing flexibility in implementation while maintaining reliable data assignment
Solution Approach 2:
The information medium serves as an intermediary carrier between the trailer and the control unit, enabling automatic identification and parameter retrieval without direct complex interaction between the trailer and control systems
