Solution Overview
Problem
Existing filter systems for internal combustion engines face challenges in securely mounting and easily removing filter elements while minimizing vibration transmission and ensuring quick, safe replacement, especially with heavy filter elements.
Innovation Solution
An end plate with arc-shaped coupling elements and end stops is designed for axial engagement, allowing secure mounting during operation and easy release by counter-rotational movement, featuring coupling and release areas for secure engagement and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional filter elements use simple mounting structures, then ease of manufacture is improved, but secure mounting during operation and easy removal are compromised
Solution Approach 1:
The coupling element is divided into multiple functional segments: a basic coupling structure for mounting, and integrated end stops that create distinct coupling and release areas. This segmentation allows the single component to provide both secure mounting during operation and easy removal when needed, resolving the contradiction between manufacturing simplicity and operational reliability.
2Reliability
If filter elements are securely mounted during operation, then reliability is improved, but ease of removal for replacement deteriorates
Solution Approach 1:
The coupling element incorporates dynamic functionality through the end stops that define coupling and release areas. During normal operation, the filter element is securely locked in the coupling area. For removal, a counter-rotational movement shifts the connection to the release area, enabling easy detachment. This dynamic design resolves the contradiction between secure mounting and ease of removal.
3Reliability
If heavy filter elements are used for better filtration, then filtration performance is improved, but vibration transmission and difficulty of removal increase
Solution Approach 1:
The coupling element acts as an intermediary between the heavy filter element and the housing. By providing defined coupling and release areas with end stops, it mediates the connection in a way that secures the heavy element during operation while minimizing vibration transmission. The controlled engagement and disengagement points reduce unwanted vibrations, resolving the contradiction between filtration performance and vibration harmful effects.
4Productivity
If quick replacement of filter elements is enabled, then productivity is improved, but secure mounting during operation may be compromised
Solution Approach 1:
The coupling element is pre-designed with integrated end stops that create predetermined coupling and release areas. This preliminary design ensures that during quick replacement operations, the filter element automatically engages at the correct coupling area for secure mounting, then can be quickly released by moving to the pre-defined release area. This resolves the contradiction between replacement speed and secure mounting by having both functions prepared in advance.
