Solution Overview
Problem
Existing filter housings face challenges in simplifying the installation and removal of filter elements, particularly in applications where space is limited and access is restricted.
Innovation Solution
A filter housing design featuring a fastening and locking device with a U-shaped bracket element and an eccentric element that allows for one-handed operation, utilizing a pivotable mechanism to securely close and open the housing cover, enhancing ease of installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional fastening device with multiple fastening points is used, then the housing cover is securely closed, but the installation and removal process requires two hands and is time-consuming
Solution Approach 1:
The fastening device is segmented into a bracket element with multiple arm sections and a single operable eccentric element. The arm sections are distributed around the housing cover to provide secure fastening at multiple points, while the single eccentric element can be operated with one hand to control all arm sections simultaneously, enabling quick installation and removal.
Solution Approach 2:
The bracket element is designed to be pivotable relative to the housing body, allowing dynamic adjustment during the fastening process. The eccentric element converts rotational motion into linear displacement of the arm sections, enabling the transition between locked and unlocked states with a single hand operation, thereby reducing installation time.
2Reliability
If a simple fastening mechanism is used, then the installation process is quick, but the housing cover may not be securely closed
Solution Approach 1:
Multiple fastening functions are merged into a single integrated fastening device. The bracket element with its multiple arm sections provides secure closure at various points around the housing cover, while all these arm sections are controlled by a single eccentric element. This merging ensures reliable secure closure without requiring multiple independent fastening mechanisms, thus avoiding excessive complexity.
3Reliability
If multiple fastening points are distributed around the housing cover, then the closure is secure and evenly distributed, but the device becomes more complex and harder to operate
Solution Approach 1:
The single eccentric element serves multiple functions: it controls all arm sections simultaneously, provides the locking mechanism, and enables one-handed operation. The bracket element with its multiple arm sections provides both secure distributed closure and serves as the structural framework for the fastening device. This multi-functionality ensures evenly distributed closure while maintaining operational simplicity.

AI summary
A filter housing includes a housing body having an openable installation opening and a housing cover to close the installation opening, and a fastening and/or locking device to secure the housing cover in a closed position. The housing body includes an element receptacle to receive a filter element through the installation opening. The fastening and/or locking device has a U-shaped bracket element with arm sections connected to a cross beam and an eccentric element mounted rotatable on the cross beam. The bracket element pivots with respect to a bracket pivot axis such that the cross beam with the eccentric element is pivotable on a side of the housing body with the installation opening. In the closed position the eccentric element engages with the housing cover and the bracket element grips the housing cover such that a part of the housing cover is between the arm sections of the bracket element.
