Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional coupling systems are used for filter element installation and removal, then secure attachment is achieved, but the exchange process requires precise procedures and increased force expenditure which can lead to damage
Solution Approach 1:
The coupling system incorporates elastic elements that can dynamically deform during the coupling and decoupling processes. The elastic element deforms elastically during coupling to secure the filter element, and during decoupling it allows for controlled force distribution that prevents damage while maintaining secure attachment during operation.
Solution Approach 2:
The system changes the mechanical parameters of the coupling interface by using elastic deformation to transition between coupled and decoupled states. The elastic element's deformation state changes during installation and removal, allowing for simplified operations without requiring precise procedural steps or excessive force.
2Ease of operation
If traditional rigid coupling mechanisms are used, then secure holding is achieved, but installation and removal require rotational movements and increased force expenditure
Solution Approach 1:
The coupling system replaces rigid mechanical interactions with dynamic elastic deformation. The elastic element allows the filter element to be coupled and decoupled through simple linear movements without requiring rotational movements, significantly reducing force expenditure during installation and removal operations.
Solution Approach 2:
The system uses an elastic element that functions as a flexible component to achieve coupling and decoupling. This flexible element deforms during the coupling process to secure the filter element and allows for easy release without requiring high forces or complex movements, eliminating the need for rotational movements in traditional systems.
3Ease of operation
If elastic elements are used for coupling, then simplified installation and removal are achieved, but the coupling strength may be insufficient
Solution Approach 1:
The elastic element is designed to exhibit different mechanical characteristics during operation versus during exchange. During normal operation, the elastic element maintains sufficient coupling strength to securely hold the filter element. During installation and removal, the elastic deformation allows for simplified operations with reduced force requirements, effectively resolving the contradiction between strength and ease of operation.

AI summary
A hollow filter element of a fluid filter has a coupling device for connecting with a first housing part of the filter housing when removing the hollow filter element from the second housing part. The coupling device is arranged at an axial end face opening of the hollow filter element. The hollow filter element can be joined by a rotation/insertion movement with the first or second housing part. The coupling device has guiding and entraining elements arranged circumferentially. A holding element extends circumferentially at the side of the guiding and entraining elements facing axially the outer side of the hollow filter element. Coupling elements for transmitting an axial pulling force can hook behind the holding element. The guiding and entraining elements are covered by the holding element radially inwardly and are connected force-transmittingly to the holding element so that the latter can be elastically stretched radially by them.
