Filter Element Data Storage Integration via Stabilization Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter elements for fluids, particularly air, face challenges in reliably integrating and communicating with data storage units, as they are prone to positional instability and signal interference due to the lack of secure and efficient antenna arrangements.
Innovation Solution
A filter element with a data storage unit partially surrounded by a potting compound, integrated into a stabilization device, and an antenna on the filter housing for contactless communication, ensuring the data storage unit remains fixed and accessible for electronic reading, using a ring-shaped antenna for reliable signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the data storage unit is integrated into the filter element without stabilization, then the integration is simple, but the data storage unit experiences positional instability and signal interference
Solution Approach 1:
The patent introduces a stabilization device as an intermediary component between the filter element and the data storage unit. This stabilization device provides a secure mounting structure that holds the data storage unit in a fixed position, preventing positional instability and signal interference while maintaining manufacturing simplicity through modular integration.
Solution Approach 2:
The patent applies local quality by providing stabilization specifically at the location where the data storage unit is mounted, rather than stabilizing the entire filter element. The stabilization device is strategically positioned to secure only the data storage unit, ensuring positional stability and signal reliability without adding unnecessary complexity elsewhere in the structure.
2Reliability
If the data storage unit is completely surrounded by potting compound, then it is firmly secured, but electronic reading becomes difficult
Solution Approach 1:
The patent applies local quality by selectively applying the potting compound around the data storage unit rather than completely enclosing it. The compound is applied in specific areas to secure the data storage unit firmly to the stabilization device, while leaving portions exposed or accessible for electronic reading, thus balancing securing reliability with operational accessibility.
3Reliability
If the antenna is placed close to the data storage unit for better signal coupling, then communication reliability improves, but the filter element design becomes more complex
Solution Approach 1:
The patent uses the stabilization device as an intermediary platform that facilitates optimal positioning of the data storage unit relative to the antenna. The stabilization device provides a mounting structure that enables close proximity between the antenna and data storage unit for better signal coupling, while the modular design of the stabilization device keeps the overall system complexity manageable.
Data Source
AI summary
A filter element has a filter body which is closed on at least one end face by an end disc, wherein the end disc is formed from a potting compound, and has a stabilization device which is surrounded at least in some areas by the potting compound. At least one data storage unit is arranged on or in the stabilization device.
