Filter Cartridge Transponder for Multi-Parameter Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for monitoring filter cartridges require separate sensors for each operating parameter, leading to high technical and financial costs, as they can only determine pressure differences and need additional sensors for other parameters.
Innovation Solution
A method and device where a transponder in the filter is exposed to influencing factors, modifying its response behavior to detectable changes in electromagnetic signal properties, allowing for the evaluation of operating parameters without additional sensors, using chemical, biological, physical, or mechanical influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate sensors are used for each operating parameter, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The transponder is designed to perform multiple functions: it serves as both an identification carrier and a sensor for detecting operating parameters such as pressure difference, temperature, and contamination levels. By integrating these sensing capabilities into the existing transponder structure, the system eliminates the need for separate dedicated sensors for each parameter, thereby reducing device complexity while maintaining measurement precision
Solution Approach 2:
The patent combines the identification function and the monitoring function into a single transponder unit. The transponder integrates multiple sensing elements (pressure sensors, temperature sensors, contamination sensors) that work together to detect various operating parameters simultaneously, merging what would traditionally require separate sensor systems into one unified component

Data Source
AI summary
A method to determine at least one filter operating parameter. At least one transponder arranged on or in a filter cartridge of the filter is contactlessly queried by a reading device. A transponder response is analyzed to evaluate the operating parameter. The transponder is subject to influences acting on the filter cartridge. As a result of the influences that the transponder is sensitive to, or sensitivity on transparency or damping properties of a transmission path of electronic signals between the transponder and the reading device, a transponder response behavior is changed to a degree detectable by the reading device or a downstream analysis unit which enables a statement to be made about the operating parameter. A device for determining at least one operating parameter of a filter or a filter cartridge arranged on or in the filter, and a filter cartridge are both provided.
