Solution Overview
Problem
Existing separators have a small filtering area and poor oil removal efficiency due to oil adhering to the filter screen, leading to frequent cleaning and reduced filtration effectiveness.
Innovation Solution
A separator design with a housing and filtering portion that includes inclined first and second draining walls, forming a large filtering area in a small space, allowing oil fumes to adhere and flow easily for improved filtration efficiency and reduced cleaning frequency, with multiple layers of filter screens and a liquid storage area for efficient oil collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a traditional filter screen structure is used, then the device complexity is low, but the filtering area is small and oil removal efficiency is poor
Solution Approach 1:
The filter screen is transformed from a flat two-dimensional structure to a three-dimensional folded structure with multiple layers and angles. The filter surface is bent and folded to create a larger effective filtering area within the same housing volume, allowing oil fume to contact more filtering surface area while maintaining a compact device size.
Solution Approach 2:
Multiple filter layers are nested within each other in a folded configuration. The filter screen is folded back on itself multiple times, with each layer nested within the previous layer, creating a compact multi-layer filtering structure that maximizes the filtering area within the limited space of the housing.
2Ease of operation
If the filter screen is positioned horizontally, then the structure is simple, but oil adheres to the filter screen and cannot fall off easily
Solution Approach 1:
The filter screen surface is designed with curved and inclined surfaces rather than flat horizontal surfaces. The filter is folded at specific angles to create inclined draining surfaces that guide oil downward using gravity, preventing oil accumulation on the filter surface and enabling easy drainage into the liquid storage area.
Solution Approach 2:
The filter screen is arranged asymmetrically with respect to the housing, with one end positioned higher than the other to create a downward slope. This asymmetric positioning ensures that oil naturally drains from the higher end to the lower end where the liquid storage area is located, facilitating automatic oil removal without additional mechanical components.
3Productivity
If the filtering area is increased, then the filtration efficiency is improved, but the device occupies more space
Solution Approach 1:
The filter screen is folded into a three-dimensional configuration with multiple layers and angles, allowing the filtering surface to extend in multiple directions rather than occupying a single flat plane. This vertical and angular folding enables the filter to achieve a large total filtering area while maintaining a compact horizontal footprint within the housing.
Solution Approach 2:
The filter screen is designed to utilize the dynamic flow of oil fume and gravity-driven oil drainage. The folded structure creates multiple flow paths for oil fume to contact the filter surface, while the inclined surfaces enable continuous oil drainage, maximizing filtration efficiency within the available space without requiring additional volume.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances filtration efficiency by increasing the filtering area, improving oil adhesion and collection, and reducing the frequency of cleaning, thereby maintaining effective filtration performance.
Implementation Method 1
oil particles and water vapor contained in the oil fume will adhere to the filtering portion
Implementation Method 2
the oil adhering to the filtering portion after filtration can more easily flow downward along the first draining wall and the second draining wall
