Filter Guide Ramp for Automatic Electrical Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing filter systems for internal combustion engines, such as those in motor vehicles, face challenges in simplifying the installation of filter elements and establishing electrical connections, which can be complex and require precise orientation, making the process cumbersome and prone to errors.
Innovation Solution
The introduction of a guide ramp within the filter housing that guides the element-associated connecting element into a defined position relative to the housing-associated connecting element, allowing for simplified installation and automatic electrical connection through a rotational and axial movement, eliminating the need for precise orientation of the filter element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the filter element is installed without a positioning assist device, then the installation process is simple, but the positioning precision and electrical connection reliability are poor
Solution Approach 1:
A guide ramp is introduced as an intermediary component between the filter element and filter housing. The guide ramp features a screw-like course that automatically guides the element-associated connecting element into the correct position relative to the housing-associated connecting element during installation, eliminating the need for complex alignment procedures while ensuring precise positioning and reliable electrical connection.
2Reliability
If the filter element requires precise orientation for electrical connection, then the electrical connection reliability is high, but the ease of operation during installation is reduced
Solution Approach 1:
The guide ramp is designed to automatically perform the orientation and positioning function during the installation process. As the filter element is inserted into the filter housing, the screw-like course of the guide ramp self-adjusts the element-associated connecting element to the correct angular position, enabling the electrical connection to be made automatically without requiring the installer to manually orient the components.
3Volume of moving object
If the housing-associated connecting element is placed in an inaccessible location, then the compactness of the filter housing is improved, but the ease of electrical connection is worsened
Solution Approach 1:
The guide ramp employs a screw-like curved course that winds through the filter housing interior. This curved path allows the element-associated connecting element to be guided from an accessible insertion point on the filter element to an inaccessible mounting location for the housing-associated connecting element. The spiral trajectory enables the electrical connection to be established automatically while maintaining compact housing dimensions.
