Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measuring devices face challenges in reliably and simply recognizing sensors, particularly due to the need for separate lines for antenna coils and limited functionality under adverse conditions like humidity and heat.
Innovation Solution
The measuring device integrates a communication device within the measuring unit, with the transponder positioned on the data cable's connecting element, allowing bidirectional communication using an antenna coil, enabling reliable sensor recognition and operation under various conditions without additional components or complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate lines are required to feed the antenna coil to the transponder, then reliable communication is achieved, but device complexity increases
Solution Approach 1:
The patent combines the data transmission line and the antenna feed line into a single integrated data cable. The same cable that transmits measurement data also carries the electromagnetic signals needed for transponder communication, eliminating the need for separate antenna feed lines and reducing overall system complexity while maintaining reliable communication.
Solution Approach 2:
The data cable is designed to serve multiple functions simultaneously: it transmits measurement data from the sensor and provides electromagnetic coupling for transponder communication. This multi-functional design eliminates redundant components and simplifies the overall system architecture.
2Device complexity
If transponder is integrated with sensor, then communication is simplified, but sensor functionality is limited under adverse conditions
Solution Approach 1:
The system is divided into two independent parts: the sensor unit that can operate in harsh environments (humidity, heat) and the transponder unit that contains the communication interface. The sensor can function without the transponder in adverse conditions, while the transponder provides identification and calibration data when connected to the measuring device through electromagnetic coupling.
Solution Approach 2:
The data cable acts as an intermediary that enables communication between the sensor and the measuring device without requiring direct integration. The cable provides both data transmission and electromagnetic coupling for transponder communication, allowing the sensor to maintain its environmental robustness while still enabling full functionality when connected.
3Productivity
If transponder is located close to sensor, then data transmission is efficient, but sensor disconnection becomes difficult
Solution Approach 1:
The transponder is placed on the connector portion of the data cable rather than being permanently integrated with the sensor element. This allows the sensor to be easily disconnected from the cable for maintenance or replacement, while the transponder remains on the reusable connector assembly.
Solution Approach 2:
Instead of attaching the transponder to the sensor (which would make sensor replacement difficult), the transponder is attached to the connector end of the cable. This reverses the conventional approach and makes the sensor maintenance-friendly while keeping the transponder in close proximity to the measuring device for efficient communication.
