Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter systems, such as those described in EP 2 939 725 A1 and EP 3 453 443 A1, lack the ability to independently exchange filter elements of different stages, leading to incomplete utilization of separation capacity and inadequate harmful gas separation.
Innovation Solution
A filter apparatus with a filter housing and adapter frame that allows for the independent exchange of multiple filter elements, each with a circumferentially extending seal, enabling a multi-stage filtration system by using an adapter frame to seal and secure the elements to the housing parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If filter medium bodies of gas filter stage and particle filter stage are connected non-detachably to each other, then structural stability is improved, but filter element exchangeability deteriorates
Solution Approach 1:
The filter apparatus is divided into separate filter elements (gas filter element and particle filter element) that can be independently exchanged. Each filter element contains its own filter medium body and seal, allowing selective replacement of individual stages without affecting the other stage's filter element.
Solution Approach 2:
A common frame serves as an intermediary component that holds both filter elements and provides a unified mounting interface to the filter housing. This common frame enables the filter elements to be separately exchangeable while maintaining stable connection to the housing through the shared frame structure.
2Device complexity
If a single filter element with one filter stage is used, then device complexity is reduced, but separation capacity utilization becomes incomplete
Solution Approach 1:
The filtration system uses multiple separate filter elements (gas filter element and particle filter element) instead of a single combined element. This segmentation allows each filter element to be optimized for its specific filtration stage while maintaining relatively simple individual structures.
Solution Approach 2:
The common frame provides a universal mounting structure that accommodates both types of filter elements with different functions (gas filtration and particle filtration). This multi-functional design allows a single framework to support multiple filtration stages with different separation capacities.
3Reliability
If filter elements are connected non-detachably, then connection reliability is improved, but adaptability of filter system deteriorates
Solution Approach 1:
The filter system transitions from a static non-detachable connection to a dynamic configuration where filter elements can be independently removed and replaced. The seals provide reliable connection during operation, while the modular design enables easy reconfiguration and adaptation to different filtration requirements.
Solution Approach 2:
By segmenting the filter system into independently exchangeable filter elements mounted on a common frame, the system achieves both reliable operation during use and high adaptability for maintenance and configuration changes.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables optimal utilization of separation capacity by allowing separate exchange and sealing of filter elements, improving filtration efficiency and enabling both particle and gas separation in a single system.
Implementation Method 1
a seal circumferentially extending around the filter medium body; at which a circumferentially extending seal of the first filter element rests seal-tightly; at which a circumferentially extending seal of the second filter element rests seal-tightly
Implementation Method 2
each comprising a filter medium body; enabling both particle and gas separation in a single system; one represents a gas filter stage and another one a particle filter stage
