Filter Cartridge Interlock with Integrated Locking Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in correctly removing and installing water filters in appliances due to alignment issues and lack of indication for proper installation, leading to potential contamination and reduced appliance performance.
Innovation Solution
A mechanical interlock system comprising a filter cartridge with an integrated locking head and a manifold, featuring a key and displaceable latch features that align and secure the filter, preventing incorrect rotation and ensuring proper installation through a push-to-lock and twist-to-unlock mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional filter installation system is used, then the filter can be easily removed and installed, but users face alignment issues and lack of indication for proper installation
Solution Approach 1:
The system provides self-aligning features where the key and keyway automatically guide the filter cartridge into the correct rotational position during insertion. The displaceable latch features engage with receptacles only when properly aligned, ensuring reliable installation without requiring user knowledge of complex alignment procedures.
Solution Approach 2:
The mechanical interlock system provides immediate tactile and visual feedback when the filter is correctly installed. The displaceable latch features engage with audible or tactile clicks, and the system may include indicators that show when the filter cartridge is properly seated and locked, giving users clear confirmation of correct installation.
2Reliability
If a mechanical interlock system with key and latch features is implemented, then proper filter alignment and secure installation are ensured, but the device complexity increases
Solution Approach 1:
The locking and alignment functions are merged into a single integrated mechanism. The key serves both as an alignment guide and as a locking element, while the displaceable latch features combine retention and alignment verification functions. This integration reduces the number of separate components compared to traditional multi-component locking systems.
Solution Approach 2:
The key and keyway structure serves multiple functions: it guides the filter cartridge during insertion, prevents incorrect installation, provides rotational alignment, and engages with the displaceable latch features to secure the filter. This multi-functionality reduces the need for separate alignment and locking mechanisms.
3Reliability
If the filter cartridge includes an integrated locking head with key and latch features, then correct installation is ensured, but the manufacturing complexity increases
Solution Approach 1:
The locking head is integrated directly into the filter cartridge body as a single molded or machined component rather than being assembled from multiple parts. The key, latch features, and alignment elements are formed as one piece, simplifying the manufacturing process and reducing assembly steps while ensuring precise geometric relationships between components.

AI summary
A mechanical interlock system for a fluid filter is described herein. The mechanical interlock system may include a filter cartridge and a manifold for receiving the filter cartridge. The filter cartridge may include a filter body, a fluid inlet and outlet, and an integrated locking head. The integrated locking head may include a key extending radially outward from the integrated locking head and displaceable latch features. The manifold may include an extraction guide for receiving the key. The extraction guide may include a primary keyway and a secondary keyway. The key, keyways, displaceable latch features, and/or receptacles may interact to maintain alignment of the filter cartridge during insertion of the filter cartridge into an appliance including the manifold.
