Vehicle Filter Mounting Grooves for Secure, Easy Element Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices for motor vehicles face challenges in securely fastening and easily exchanging filter elements, particularly in environments with vibrations and pressure pulses, while ensuring the right filter is used for the application situation.
Innovation Solution
A filter device with a filter element and frame, featuring engagement elements that fit into grooved counter elements in the filter housing, allowing for form-fit connections and easy mounting, including insertion and blocking sections that provide stability and versatility in mounting configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If engagement elements with form-fit connections are used to securely fasten filter elements, then the filter element remains fixed during vibrations and pressure pulses, but the mounting and exchange process becomes more complex
Solution Approach 1:
The engagement counter element is divided into two functional sections: an insertion section that guides the engagement element during mounting, and a blocking section that secures the engagement element in the final position. This segmentation allows the fastening mechanism to provide secure fixation while maintaining simple mounting operations through the guidance function of the insertion section.
2Ease of operation
If simple engagement elements are used for easy filter exchange, then the mounting process becomes simpler, but the filter element may not remain securely fixed during vibrations and pressure pulses
Solution Approach 1:
The engagement element automatically performs both functions: during insertion, the insertion section guides it into place (self-guidance), and upon reaching the blocking section, the element self-secures without additional fastening steps. This self-service mechanism enables simple filter exchange while ensuring reliable fixation under vibrations and pressure pulses.
3Adaptability or versatility
If multiple engagement elements are used to ensure proper filter positioning, then the risk of using incorrect filters is reduced, but the device complexity and mounting time increase
Solution Approach 1:
The engagement counter element with its dual-section structure (insertion and blocking) serves multiple functions: it guides the engagement element, secures it in position, and can be replicated across multiple locations on the filter housing. This universal design allows the same simple structure to be used repeatedly, ensuring filter compatibility without proportionally increasing overall system complexity.

AI summary
A filter device has a filter element with filter medium body and surrounding frame with opposed lateral faces. A filter housing has opposed wall sections with two engagement counter elements for receiving with form fit an engagement element, respectively. The engagement counter elements are grooves in the wall sections with an insertion section and a blocking section connected to the insertion section and angled thereto. The insertion section permits insertion of the engagement element along a flow direction through the filter element. In the mounted state, the engagement element is arranged at one of the lateral faces of the frame, extends away from the filter medium body, and is held in the blocking section. One or several of the engagement elements are separate parts fastenable detachably to the filter element. A vehicle with such a filter device and a method for mounting the filter element with engagement elements are provided.
