Foldable Filter With Support Assembly For Stable Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable air filters require complex installation processes and are prone to damage during replacement, as they rely on sliding mounting brackets that can scratch the filter body, affecting their filtering efficiency.
Innovation Solution
A foldable filter with a support system that includes a filter main body, end components, and a supporting assembly, allowing for stable installation without a sliding mounting bracket, with adjustable 'X' shaped supporting members and sliding blocks to switch between stowed and in-use states, ensuring easy operation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a sliding mounting bracket is used to connect mounting plates, then the filtering assembly stability is improved, but the device complexity increases and the filter body is prone to scratching
Solution Approach 1:
The patent removes the sliding mounting bracket from the system entirely. Instead of using a separate bracket component to connect mounting plates, the design integrates the support function directly into the mounting plates themselves, which are equipped with support ears that can be directly fastened to the air purifier frame, thereby simplifying the overall structure while maintaining stability
Solution Approach 2:
The mounting plate is segmented into functional components including the plate body and support ears. The support ears are distinct structural elements that extend from the mounting plate to provide attachment points, allowing the mounting plate to perform both mounting and support functions independently without requiring additional brackets
2Stability of the object's composition
If a sliding mounting bracket is used to connect mounting plates, then the filtering assembly stability is improved, but the ease of operation deteriorates due to multiple operational steps
Solution Approach 1:
By removing the sliding mounting bracket entirely, the patent eliminates the complex multi-step operation of attaching and detaching brackets. The mounting plates with integrated support ears can be directly fastened to the frame using simple fastening operations, significantly reducing the number of steps required for filter installation and replacement
Solution Approach 2:
The mounting and support functions are merged into a single integrated component (the mounting plate with support ears). This consolidation eliminates the need for separate bracket components and their associated attachment/detachment operations, making the filter replacement process simpler and more straightforward
3Stability of the object's composition
If a sliding mounting bracket is used to connect mounting plates, then the filtering assembly stability is improved, but the reliability deteriorates due to scratching of the filter body
Solution Approach 1:
The patent removes the sliding mounting bracket that causes scratching of the filter body during installation and operation. By eliminating this contact component, the filter main body is protected from mechanical damage, ensuring its sealing surface remains intact and the filtering effect is maintained throughout the product lifecycle

AI summary
A foldable filter with a support includes a filter main body, two end components and a supporting assembly. The filter main body provided with an upper end, a lower end, and a pleated medium extending between the upper end and the lower end. The two end components are respectively connected to the upper end and the lower end of the filter main body, the two end components are adjacent or away from each other. The filter main body switches between a stowed state and an in-use state. An upper end of the supporting assembly is connected to the end component positioned at an upper end, a lower end of the supporting assembly is connected to the end component positioned at a lower end. The supporting assembly limits a distance between the two end components to fix the filter main body in either the stowed state or the in-use state.
