Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oil catch apparatuses are bulky due to the need for a specific distance for air to collide with a collision plate, making them inefficient in size and space utilization for oil separation.
Innovation Solution
A compact oil catch apparatus featuring a cylindrically formed main filter unit with a metallic network sheet and resinous mesh sheet element, supported by keep members and incorporating a muffler for enhanced separation and muffling effects, allowing efficient oil extraction within a limited space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If air is made to collide with a collision plate for oil separation, then oil separation efficiency is improved, but apparatus size increases due to required collision distance
Solution Approach 1:
The patent transitions from a linear collision plate design requiring axial collision distance to a cylindrical filter element design where separation occurs radially through the wall thickness dimension. Air flows axially through the element, and oil separates radially outward through the cylindrical wall, eliminating the need for extended axial collision space.
Solution Approach 2:
The filter element is constructed with a porous or mesh structure (metallic network sheet and resinous mesh sheet) that allows air to pass through while intercepting and separating oil particles. The porous/cylindrical wall structure provides large surface area for oil separation within a compact volume, replacing the need for extended collision distance.
2Volume of stationary object
If a compact filter design is used, then apparatus size is reduced, but oil separation effectiveness may be compromised
Solution Approach 1:
By utilizing the radial dimension of the cylindrical wall for oil separation, the design achieves effective separation within a compact axial footprint. The oil separation function is distributed throughout the cylindrical wall thickness rather than requiring extended linear distance, maintaining effectiveness while reducing overall apparatus size.
Solution Approach 2:
The filter element combines metallic network sheet and resinous mesh sheet in a composite cylindrical structure. This composite construction provides both mechanical strength and effective oil separation capability within a compact form factor, ensuring separation effectiveness is not compromised by the reduced size.
Applied Scientific Principles

Function Achieved in This Case
The apparatus effectively separates and collects oil while maintaining a compact size, suppressing oil splashing and enhancing muffling effects, thus achieving efficient oil extraction and space-saving design.
Implementation Method 1
a main filter unit (2); a first keep member (3) for keeping one end of the main filter unit (2); and a second keep member (4) for keeping the other end of the main filter unit (2). Air flowing into the main filter unit (2) from an opening (3a) formed in the first keep member (3) is cleared of impurities upon passing through the main filter unit (2)
Implementation Method 2
The oil catch apparatus (100) further includes a muffler (7) arranged inside the main filter unit (2)

AI summary
A filter for an oil catch apparatus is provided. The oil catch apparatus is capable of efficiently extracting oil from air flowing through the oil catch apparatus while being of compact size. The filter includes a cylindrically wound main filter unit, a first keep member for keeping one end of the main filter unit, and a second keep member for keeping the other end of the main filter unit. Air flowing into the main filter unit from an opening formed in the first keep member is cleared of impurities upon passing through the main filter unit, and exits out of the main filter unit.
