Filter Screen Bracket Assembly to Reduce Deformation During Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioner fresh air modules suffer from filter screen deformation due to collisions with other components during installation or removal, as the filter screens are typically made of soft materials and lack adequate support.
Innovation Solution
The fresh air module incorporates a filter screen bracket with a frame body and a cover member that includes a handle element, a limiting member, and a buckle or elastic push fastener system, allowing the filter screen to be securely mounted and reducing deformation risk by distributing forces and providing a secure attachment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter screen is made of soft material for filtering outside air, then the filtering function is improved, but the filter screen is easily deformed due to collisions with other components when drawing the filter screen
Solution Approach 1:
The filter assembly is divided into two separate components: a soft filter screen for filtering and a rigid bracket for structural support and handling. The bracket is segmented into a frame body surrounding the filter screen and a separate cover member that can be independently manipulated, allowing the soft filter to remain protected while enabling easy installation and removal through the cover member's handle element.
Solution Approach 2:
The bracket acts as an intermediary between the soft filter screen and the external environment. It provides a rigid framework that protects the soft filter material from direct collisions and deformations, while still allowing the filter screen to perform its filtering function. The cover member serves as an additional intermediary for handling, eliminating direct contact with the filter screen itself.
2Device complexity
If the filter screen is mounted directly without a bracket, then the device complexity is reduced, but the filter screen is vulnerable to damage during handling and installation
Solution Approach 1:
The mounting structure is segmented into a frame body that provides structural support and a separate cover member that enables handling. This segmentation allows the filter screen to be protected by the frame while the cover member with its handle element provides easy access for installation and removal, balancing complexity with protection.
Solution Approach 2:
The cover member with the handle element enables users to easily grasp and manipulate the entire filter assembly without needing to directly touch or handle the filter screen itself. The design serves its own protection function through the integrated handle that provides secure grip points for safe installation and removal.
3Strength
If a rigid structure is used to support the filter screen, then the resistance to deformation is improved, but the ease of manufacture and assembly is reduced
Solution Approach 1:
The rigid support structure is segmented into a frame body and a separate cover member, allowing each component to be manufactured independently using simple processes. The frame body provides the necessary rigid support for the filter screen, while the cover member with its handle element can be separately attached, simplifying the overall manufacturing and assembly process compared to a single complex rigid structure.
Solution Approach 2:
The frame body and cover member are combined to form a complete filter assembly that integrates structural support with easy handling. The merging of these two simple components creates a robust structure that is both easy to manufacture and provides excellent protection during installation and removal operations.
