Reusable Air Filter With Removable Washable Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air filtration devices are not effectively reusable, leading to waste and inefficiency in indoor air quality management, as they are typically disposable and lack features for easy cleaning and replacement, which contributes to respiratory issues due to airborne microbes and particulates.
Innovation Solution
A modular, washable air filtration device with a removable filter component secured by zippers or elastic members, allowing for easy cleaning and reattachment, and adjustable frame members for customizable fit and efficient packaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If disposable filter elements are used, then air filtration is achieved, but waste is generated and the device cannot be reused
Solution Approach 1:
The air filtration device is divided into separable components: a reusable frame and a removable filter element. The frame can be repeatedly used while the filter element is detached, cleaned, and reattached, eliminating waste and enabling reuse of the main device structure.
Solution Approach 2:
Instead of discarding the entire filter device after use, the patent enables recovery and reuse of the frame structure. The filter element is removed for cleaning and reattachment, while the frame remains in service, significantly reducing material waste and extending device life.
2Ease of operation
If the filter component is permanently attached to the frame, then structural integrity is maintained, but cleaning and replacement are difficult
Solution Approach 1:
The attachment mechanism transitions from permanent to dynamic/reversible. The filter element can be easily attached and detached from the frame using simple mechanical means (such as elastic members or clips), allowing frequent removal for cleaning while maintaining structural integrity during operation.
3Volume of stationary object
If the frame is rigid and fixed, then stability is provided, but packaging efficiency and storage space are reduced
Solution Approach 1:
The frame structure incorporates adjustable or collapsible elements that allow it to transition between a stable operational configuration and a compact storage configuration. This enables efficient packaging and storage while maintaining structural integrity when the device is in use.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides enhanced cleaning efficiency and effectiveness while reducing waste, allowing for frequent cleaning and reuse, thus improving indoor air quality and reducing respiratory issues by effectively capturing airborne pollutants and microbes.
Implementation Method 1
The filter member is provided in a reusable device and secured to the frame member. The filter member is removable from the frame member to facilitate cleaning and/or replacement of the filter member and wherein at least a portion of the air filter device is provided as a reusable device.
Implementation Method 2
The filter member is removable from the frame member to facilitate cleaning and/or replacement of the filter member
