Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel cell and pesticide filters struggle to accurately predict their service life due to varying ambient conditions, often requiring a high safety margin, which results in shorter-than-necessary service intervals and increased costs due to premature replacement.
Innovation Solution
A filter body with multiple filter layers and integrated sensor devices, where each sensor is positioned between two filter layers, allowing for precise monitoring of the sorption capacity of each layer over the filter's service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensor devices are integrated between filter layers to monitor sorption capacity, then measurement precision of filter service life is improved, but device complexity increases
Solution Approach 1:
The filter medium is divided into multiple filter layers (first, second, third filter layers) with sensor devices positioned between them. This segmentation allows independent monitoring of sorption capacity at different stages of the filtration process, enabling precise determination of when each layer reaches breakthrough without requiring a single complex sensor system.
Solution Approach 2:
Sensor devices are positioned as intermediaries between the filter layers to detect the sorption capacity status. These sensors act as mediators that translate the chemical state of the active material into measurable signals, allowing indirect but accurate monitoring of filter performance without direct contact with the filtered medium.
2Manufacturing precision
If sensor devices are arranged between each neighboring filter layer, then sorption capacity monitoring precision is improved, but manufacturing complexity increases
Solution Approach 1:
The filter body is manufactured as segmented layers with sensor devices integrated between them. This modular approach allows each layer-sensor assembly to be prepared separately and then combined, improving positioning accuracy while maintaining manufacturing ease through standardized assembly procedures.
Solution Approach 2:
Sensor devices are pre-positioned between filter layers during the manufacturing process rather than being installed afterward. This preliminary action ensures precise positioning is built into the structure from the start, eliminating the need for complex post-assembly calibration or adjustment procedures.
3Duration of action of stationary object
If multiple filter layers with identical active material are used, then service life extension is achieved, but loss of substance increases due to premature replacement
Solution Approach 1:
The filter is segmented into multiple layers, each capable of independent sorption. This allows the filter to continue functioning even when one layer reaches breakthrough, extending the overall service life and reducing the frequency of replacements, thereby reducing the total amount of active material consumed over time.
Solution Approach 2:
Sensor devices provide feedback on the sorption capacity of each filter layer, enabling the system to determine the actual service life based on real-time performance data rather than fixed time intervals. This prevents premature replacement and optimizes the utilization of the active material in each layer.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables a more accurate prediction of the filter's service life, allowing for longer service intervals and reducing unnecessary replacements, thereby optimizing costs and performance.
Implementation Method 1
The filter layers comprise each at least one active material, wherein the at least one active material is the same in all filter layers. Preferably, the active material comprises at least one sorbent or sorption material that is the same in all filter layers.
Implementation Method 2
Herein, 'sorption' is to be understood as processes that lead to accumulation of a substance within a phase or at a boundary surface between two phases. The accumulation within a phase is more precisely referred to as absorption
Implementation Method 3
the sensor devices in a through-flow direction of the filter body are arranged one after another in order to determine a sorption capacity of the active material of the individual filter layers over a service life of the filter body

AI summary
A filter body is provided with a filter medium that has filter layers arranged one over the other, wherein each filter layer is provided with at least one active material. The at least one active material is the same in all of the filter layers. The filter layers are to be flowed through serially in a through-flow direction of the filter body. Sensor devices are provided, wherein each sensor device is arranged between two of the filter layers neighboring each other, respectively, so that the sensor devices, in the through-flow direction of the filter body, are arranged one after another in order to determine a sorption capacity of the at least one active material of each filter layer over a service life of the filter body.
