Movable Filter Holder for Ergonomic Air Filter Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing air filter replacement process in vehicles is time-consuming and ergonomically challenging for service technicians due to the conventional cylindrical design of air filters, which requires cumbersome handling and alignment during replacement.
Innovation Solution
A movable filter holder portion within the air filter housing allows the air filter unit to be easily extended and retracted, providing full accessibility for filter replacement, enabling convenient and efficient swapping of the filter unit without the need for extensive manual manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional cylindrical air filter design is used, then the air filter can be easily manufactured and installed, but the replacement process is time-consuming and ergonomically challenging for service technicians
Solution Approach 1:
The air filter assembly is segmented into two main parts: a stationary housing and a movable filter holder portion that can be independently extracted. This segmentation allows the filter holder to be removed from the housing for convenient filter replacement, while the housing remains fixed and easily manufacturable.
Solution Approach 2:
The filter holder portion is designed with movable elements (such as a movable wall or telescopic structure) that allow it to extend outward from the housing during replacement and retract into the housing during normal operation. This dynamic capability enables easy filter access without compromising the compact design.
2Stability of the object's composition
If the air filter is housed within a fixed cavity, then the structure is simple and stable, but the filter replacement requires extensive manual manipulation and alignment
Solution Approach 1:
The filter holder portion incorporates movable walls or telescopic structures that enable it to extend outward from the housing when filter replacement is needed and retract into the housing during normal operation. This dynamic mechanism provides full accessibility for filter swapping while maintaining a compact, stable structure during use.
Solution Approach 2:
The filter holder portion is designed to be completely extractable from the housing, allowing the entire holder with the filter attached to be removed as a single unit. This extraction capability eliminates the need for complex manual manipulation and alignment during filter replacement.
3Volume of moving object
If the filter holder portion is always retracted inside the filter cavity, then the structure is compact, but the filter replacement is time-consuming and labor-intensive
Solution Approach 1:
The filter holder portion is designed to be movable between two positions: retracted inside the filter cavity during normal operation to maintain compactness, and extended outward when filter replacement is needed to enable quick and easy filter swapping.
Solution Approach 2:
The movable filter holder portion is positioned and prepared in advance within the housing, allowing the filter to be quickly accessed and replaced without requiring extensive manual manipulation or alignment during the actual replacement process.
