Air Handler Filter Plate Design for User-Replaceable Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioner filters are difficult to replace and require professional assistance, leading to high replacement costs and inefficiencies.
Innovation Solution
An air handling apparatus with a shell, filter plate, and filter chamber, where the filter is easily removable and replaceable through snap, adhesive, or adsorption structures, and includes a filter-replacement reminding device with sensors and an alarm for timely replacement, as well as an automatic filter-replacement system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter is firmly fixed in the air conditioner, then the filter can be securely held in place, but the filter becomes difficult to replace and requires professional technical personnel
Solution Approach 1:
The filter assembly is divided into separable components: the filter element and the filter holder (or filter plate). This segmentation allows the filter to be securely fixed during operation while enabling easy removal and replacement by users without requiring professional technical personnel.
Solution Approach 2:
The fixation mechanism transitions from a static permanent fixation to a dynamic reversible fixation. The filter can be firmly fixed during normal operation but can be easily removed when needed, achieving both reliable fixation and ease of replacement through a convertible fixation state.
2Ease of operation
If the filter replacement process is simplified for user convenience, then filter replacement becomes easier and cheaper, but the filter may become loose or improperly installed
Solution Approach 1:
The filter replacement process is designed to be a self-service operation that users can perform independently. The simple fixation mechanism allows users to easily install and replace filters themselves without requiring professional technical personnel, while still ensuring reliable fixation through the designed connection structure.
Solution Approach 2:
Complex mechanical fixation systems are replaced with simpler connection mechanisms such as snap-fit structures, adhesive structures, or adsorption structures. This substitution maintains installation reliability while significantly improving ease of operation and enabling user-friendly replacement.
3Reliability
If professional technical personnel are required for filter replacement, then proper installation can be ensured, but replacement costs increase and efficiency decreases
Solution Approach 1:
The filter replacement system is designed to enable self-service by end users. The simplified fixation mechanism allows users to independently perform filter replacement without requiring professional technical personnel, thereby improving replacement efficiency and reducing costs while maintaining installation quality through the designed connection structure.
4Ease of operation
If the filter structure is made simple for easy replacement, then user replacement becomes feasible, but the filter may not be securely held during operation
Solution Approach 1:
The filter system is segmented into the filter element and a separate fixation structure (filter holder or filter plate). This segmentation allows the filter element to be simple and easy to replace while the fixation structure provides the necessary strength and security during operation, resolving the contradiction between simplicity and strength.

AI summary
An air handling apparatus is provided. The air handling apparatus can include a shell, a filter plate, a filter chamber, and a filter. The shell is provided with a hole. The filter plate is connected to the shell through a first connecting member and configured to cover the hole. The filter chamber is arranged in the shell and communicated with the hole. The filter is inserted in the filter chamber through the hole. A cross-sectional size of the filter is less than or equal to a cross-sectional size of the hole.
