Coiled Hydraulic Filter With Spring Retention for Tight Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic filter designs for automotive applications, such as those in braking systems, face challenges with weight, size constraints, and material usage, particularly in space-constrained areas, where integrally formed filters are costly and standalone filters add significant weight and space requirements.
Innovation Solution
A coiled mesh-like filter structure is configured to provide radial spring force retention around a cylindrical hydraulic component, pre-coiled to fit within an undercut portion and installed by stretching and allowing elastic return to engage securely without additional space, with optional spot-welding for added security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standalone filter is used, then the filter can be easily installed and removed, but it takes up substantial surface area and adds significant weight
Solution Approach 1:
The filter is merged with the cylindrical body by wrapping the coiled filter around the body and securing it with formed wire, creating an integrated assembly that reduces overall weight while maintaining ease of installation and removal
Solution Approach 2:
The filter uses a coiled mesh-like structure that is flexible and can be wrapped around the cylindrical body, providing filtration functionality with minimal material usage and reduced weight compared to rigid standalone filters
2Ease of operation
If a standalone filter is used, then the filter can be easily installed and removed, but it takes up substantial surface area
Solution Approach 1:
The filter is combined with the cylindrical body surface, wrapping around it to utilize the existing surface area rather than adding separate mounting space, thereby reducing the overall surface area occupied in space-constrained areas
Solution Approach 2:
The coiled filter structure is nested around the cylindrical body, with the formed wire wrapping around both the filter and body to secure them together, creating a compact integrated assembly that minimizes surface area usage
3Reliability
If an integrally formed filter is used, then the filter provides robust protection, but it increases manufacturing cost and R&D requirements
Solution Approach 1:
The filter system is segmented into separate components: the coiled mesh filter element and the cylindrical body, allowing the filter to be manufactured independently and assembled later, thereby reducing overall manufacturing cost and R&D requirements while maintaining reliable filtration protection
4Reliability
If the filter is wrapped around the cylindrical body, then the filter provides effective filtration, but it requires additional retention mechanisms such as spot welds or formed wire
Solution Approach 1:
The coiled mesh-like structure of the filter provides flexibility that allows it to be wrapped around the cylindrical body and secured with simple formed wire wrapping, achieving effective filtration without complex retention mechanisms

Function Achieved in This Case
The coiled filter design offers a lightweight, compact solution that effectively prevents foreign matter from entering hydraulic components while maintaining secure retention without increasing the component's size or weight, enhancing the efficiency and reliability of hydraulic systems.
Implementation Method 1
the filter is configured to have a radial spring force as a retention force which couples the filter to the first surface of the cylindrical hydraulic component
Implementation Method 2
the filter is configured to prevent foreign matter from flowing into the cylindrical hydraulic component
Implementation Method 3
The filter may be configured to be pre-coiled prior to installation by plastically deforming to a second diameter that is smaller than a first diameter of a first surface of the cylindrical hydraulic component
