Hollow Filter Grip Device for Airflow Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air filter elements for internal combustion engines and other machinery face challenges in providing a space-efficient grip mechanism that does not disrupt airflow during installation, removal, or operation.
Innovation Solution
A grip device is strategically arranged on an end face of the hollow filter element that is not part of the airflow path, allowing for secure handling and installation without affecting airflow functionality, and can be made from materials like plastic, metal, or carbon fiber compounds, offering flexibility and mechanical stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a grip device is added to the hollow filter element for easy handling, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The grip device is integrated with the end member to form a single unified component. The end member serves dual purposes: sealing the filter element and providing the grip function. This merging eliminates the need for separate grip components, thereby improving ease of operation while avoiding additional device complexity
Solution Approach 2:
The end member is designed to perform multiple functions simultaneously: it acts as a sealing element against the filter housing and as a grip device for handling the filter element. This multi-functionality approach allows the same component to serve both sealing and gripping purposes, resolving the contradiction between improved operability and increased complexity
2Ease of operation
If the grip device is arranged on the end face for secure gripping, then ease of operation is improved, but airflow functionality may be affected
Solution Approach 1:
The grip device is positioned specifically on the end face in a location that does not interfere with the airflow path. The end member with integrated grip features is arranged at the closed end of the filter element, away from the air inlet and outlet openings. This localized placement ensures secure gripping functionality while maintaining uninterrupted airflow through the filter element
Solution Approach 2:
The grip function is extracted and placed on the end face separate from the main filtering body and airflow path. By positioning the grip device on the end member rather than on the cylindrical surface or near the air openings, the gripping function is separated from the airflow function, allowing both to operate independently without interference

AI summary
A hollow filter element of a filter device for filtering air is arranged exchangeably in a filter housing of the filter device so that at least one air inlet of the filter housing for air to be filtered is separated from at least one air outlet of the filter housing for filtered air. The hollow filter element is provided with at least one filter bellows made of at least one filter medium surrounding at least one element interior circumferentially relative to an element axis of the hollow filter element. At least one grip device is arranged at an end face of the at least one filter bellows that is not provided for passage of air in operation of the hollow filter element. The hollow filter element can be gripped by the at least one grip device at least for installation into or removal from the filter housing.
