Push-Twist Housing with Anti-Rotation Lock for Filter Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air filter systems for combustion engines face challenges in compact mounting spaces, where traditional housing designs are difficult to open and close comfortably due to limited space and require complex torque adjustments for secure locking.
Innovation Solution
A housing with a push-twist structure and anti-rotation lock system, featuring a clip element that connects to an anchor portion in a predominantly circumferential mounting direction, allowing for easy opening and closing even in tight spaces, using a bayonet-type connection and rib-and-detent mechanism for secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional housing designs are used with complex torque adjustment mechanisms, then secure locking is achieved, but the device complexity increases and ease of operation deteriorates in limited mounting spaces
Solution Approach 1:
The patent extracts the torque adjustment mechanism from the housing connection system and replaces it with a simple clip element that engages with an anchor portion. The clip element's elastic deformation provides the locking force without requiring complex adjustment mechanisms, thus reducing device complexity while maintaining secure locking.
Solution Approach 2:
The clip element is designed to automatically adjust its locking force through elastic deformation when engaged with the anchor portion. The system self-regulates the locking torque through the clip's material properties and geometry, eliminating the need for external torque adjustment mechanisms and simplifying operation.
2Reliability
If traditional housing designs are used with multiple locking devices, then secure locking is achieved, but the ease of operation deteriorates in limited mounting spaces
Solution Approach 1:
The patent merges multiple locking functions into a single integrated clip element that performs both locking and torque regulation through its elastic deformation. This single component replaces multiple separate locking devices, making the housing easy to operate in limited spaces while maintaining secure locking.
Solution Approach 2:
The patent removes unnecessary intermediate locking components and directly connects the clip element to the anchor portion, eliminating complex multi-step locking procedures. This simplification enables easy operation with one hand even in confined mounting spaces.
3Ease of operation
If more mounting space is provided for comfortable operation, then ease of operation improves, but the volume of the housing system increases
Solution Approach 1:
The clip element functions as a flexible elastic component that provides the necessary locking force through its deformation. This flexible element enables comfortable operation with minimal space requirements, as it can be actuated by small manual forces without requiring large mounting volumes.
Solution Approach 2:
The patent changes the physical state of the clip element from rigid to elastic, allowing it to deform and provide locking force within a compact volume. This parameter change enables comfortable operation in limited spaces by utilizing material elasticity rather than mechanical leverage requiring large dimensions.
