Filter Mounting Assembly With Covered Connecting Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices in gas turbines are prone to damage due to connecting elements detaching and being sucked into the turbine, despite high demands for protection against dust and solids.
Innovation Solution
A mounting assembly design where a second filter element is positioned to cover the first connecting element, ensuring it remains secured and protected, thereby preventing detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connecting elements are used to attach filter elements to the mounting element, then the filter device can be assembled and disassembled, but the connecting elements may detach and be sucked into the gas turbine causing damage
Solution Approach 1:
The connecting element is nested within the frame element structure. The frame element has a receiving space that accommodates the connecting element, and a cover element that closes this space, effectively nesting the connecting element within the frame element's protective enclosure. This prevents detachment while maintaining assembly/disassembly capability.
Solution Approach 2:
The cover element acts as an intermediary component between the frame element and the connecting element. It mediates by providing a protective closure that secures the connecting element within the frame element's receiving space, preventing direct exposure and potential detachment while allowing controlled access for assembly and disassembly.
2Reliability
If additional components are added to cover or secure the connecting elements, then the reliability increases, but the device complexity and material costs increase
Solution Approach 1:
The cover element serves multiple functions simultaneously: it closes the receiving space of the frame element, protects the connecting element from detachment, and maintains the structural integrity of the filter element assembly. This multi-functionality reduces the need for separate dedicated protective components, thereby reducing overall device complexity while improving reliability.
