Solution Overview
Problem
Existing compressed air filter arrangements face challenges with restricted flow relationships due to space-saving installations and accessibility issues, leading to increased flow resistance and maintenance difficulties as filter elements clog over time.
Innovation Solution
A compressed air filter adapter with a flow duct featuring offset openings and a non-circular outer contour, optimized for improved flow conduction by creating free space and reducing flow resistance, allowing for efficient connection to a filter connection housing while facilitating easy insertion and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter element is seated within a filter connection housing to facilitate replacement, then the filter element can be easily replaced at maintenance intervals, but restricted flow relationships form due to space-saving installation requirements
Solution Approach 1:
The adapter is divided into distinct functional zones: a first opening for connection to the filter housing, a second opening for the filter element, and an offset flow duct connecting them. This segmentation allows each zone to be optimized independently - the offset configuration creates additional flow space while the sealing zones maintain connection integrity, resolving the conflict between easy replacement and flow performance.
Solution Approach 2:
The invention transitions from a simple aligned opening configuration to an offset three-dimensional arrangement. The flow duct is positioned at an offset relative to the openings, creating a spatial configuration that provides adequate flow cross-section and prevents restricted flow relationships, while still maintaining compact overall dimensions for space-saving installation.
2Volume of moving object
If space-saving installation is implemented in the filter connection housing, then the installation footprint is reduced, but flow resistance increases due to restricted flow relationships
Solution Approach 1:
The adapter employs an asymmetric offset design where the flow duct is deliberately positioned at an offset relative to the openings rather than in a symmetric aligned configuration. This asymmetric arrangement optimizes the flow path geometry to reduce resistance while maintaining compact dimensions, achieving the balance between space-saving installation and acceptable flow characteristics.
3Productivity
If the outer contour of the first opening is transformed from a circle with displacements, then free space is created for improved flow conduction, but the manufacturing complexity increases
Solution Approach 1:
The invention modifies the geometric parameters of the first opening by transforming the circular contour with controlled displacements and surface section adjustments. This parameter change creates the necessary free space for improved flow conduction while maintaining a systematic design approach that can be manufactured using standard precision machining or molding processes.
