Filter Housing Twist-Lock Seal Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices require additional manipulations for seal replacement during filter element maintenance, leading to potential leaks due to neglect or incorrect installation of new seals.
Innovation Solution
The filter device design incorporates positioning arms on the separating element that automatically engage with connection means interruptions, ensuring the seal is replaced and correctly positioned during filter element changes, preventing leaks and simplifying maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the seal is arranged separately on the housing part, then the seal can be installed independently, but additional manipulations are required for seal replacement during filter element maintenance, leading to potential leaks due to neglect or incorrect installation
Solution Approach 1:
The patent combines the seal with the filter element to form an integrated assembly. The seal is arranged on the filter element instead of being a separate component on the housing part. This merging eliminates the need for separate seal installation manipulations during filter element replacement, ensuring that seal installation reliability is maintained without requiring additional steps that could be neglected or performed incorrectly.
2Reliability
If the seal is integrated with the filter element, then seal replacement occurs automatically with filter element change, but the seal must be positioned precisely relative to the housing part connection means
Solution Approach 1:
The patent incorporates the seal pre-positioned on the filter element during filter element manufacturing. The seal is already in its correct position and orientation on the filter element before installation into the housing part. This preliminary positioning action eliminates the need for precise positioning manipulations during assembly, as the seal is brought into the correct position automatically when the filter element is installed.
Solution Approach 2:
The filter element acts as an intermediary carrier for the seal. Instead of positioning the seal directly on the housing part, the seal is first mounted on the filter element, which then serves as the mounting substrate. This intermediary approach simplifies the positioning process, as the filter element's geometry and connection features guide the seal into the correct position relative to the housing part during assembly.
3Manufacturing precision
If additional connecting means interruptions and positioning arms are added, then the seal and filter element are automatically positioned correctly, but the device complexity increases
Solution Approach 1:
The positioning arms and connecting means interruptions serve multiple functions: they guide the filter element into correct position during installation, secure the filter element in its operational position, and ensure proper alignment of the seal with the housing part. By making these connection components multi-functional, the patent achieves precise positioning without adding separate dedicated positioning mechanisms, thereby limiting the increase in device complexity.
