Solution Overview

Problem

The operational advantages of improved filter elements are not economically viable due to compatibility issues with existing filter devices, requiring replacement of filter housings, which is costly and inefficient.

Innovation Solution

A filter element design featuring a pipe socket with a first sealing element on the inner guideway and a second sealing element on the outer guideway, allowing compatibility with both new and adapted filter housings, enabling secure fluid connection and positional security through threaded interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If improved filter elements are used, then filtration performance is improved, but compatibility with existing filter housings deteriorates

Engineering Contradiction:
Improvefiltration performanceVSAvoidcompatibility with existing filter housings
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The pipe socket is designed with a universal structure that can accommodate both first design and second design housing parts. The inner guideway interfaces with the receiving socket of the first design, while the outer guideway with external thread interfaces with the receiving socket of the second design. This multi-functional design allows the same filter element to be used with both conventional and modified filter housings, resolving the compatibility issue while maintaining improved filtration performance.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If filter housings are replaced to accommodate improved filter elements, then operational safety is improved, but cost and complexity increase

Engineering Contradiction:
Improveoperational safetyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The filter element design incorporates a dynamic adaptation mechanism where the pipe socket can interact with different housing designs through its dual guideway system. This allows the system to adapt to existing filter housings without requiring replacement, thereby maintaining operational safety improvements while avoiding the added complexity and cost of housing exchanges.

Inventive Principle:
Principle #15Dynamics

3Productivity

If filter housings are replaced to accommodate improved filter elements, then operational advantages are achieved, but economic viability deteriorates

Engineering Contradiction:
Improveoperational advantagesVSAvoideconomic viability
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The pipe socket is pre-designed with both inner and outer guideways that can accommodate different housing designs. This preliminary design consideration allows the improved filter element to be directly installed in existing filter housings without requiring any modifications or replacements, thereby achieving operational advantages while maintaining economic viability by avoiding costly housing exchanges.

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to a filter element for a filter device, having at least one filter housing (3; 4), wherein the filter element (1) comprises a receiving part (19) which, when the filter element (1) is located in the filter housing (3; 4) in the operational position, comes into fluid communication with a housing part (17; 18) of the filter housing (3; 4), which forms a fluid connection (9). The invention is characterized in that the receiving part (19) of the filter element (1) has an inner, first guiding path (37) for sealing contact to the housing part (17) of the filter housing (3) according to a first mode of construction and an outer, second guiding path (51) for sealing contact to the housing part (18) of the filter housing (4) according to a second mode of construction.
