Collapsible Filter Frame With Joining Structures for Compact Shipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a collapsible frame that provides strong support for air filter elements in HVAC systems while occupying minimal storage space and maintaining a compact package for shipping and storage.
Innovation Solution
A frame composed of alternating pairs of first and second members, which form joining structures to define a volume for receiving the filter element, allowing for collapsibility and robust support when assembled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the frame is designed to be collapsible for compact storage and shipping, then storage space occupancy is reduced, but the structural strength and support capability may be compromised
Solution Approach 1:
The frame is divided into multiple collapsible members (first members and second members) that can be segmented and reconfigured. Each member contains joining structures with movable components that allow the frame to be divided into collapsible sections while maintaining structural integrity when assembled.
Solution Approach 2:
The frame incorporates dynamic joining structures with movable walls and latching mechanisms that transition between collapsed and assembled states. The movable walls can shift positions to lock members together, providing structural strength when needed while allowing compact configuration for storage and shipping.
2Stability of the object's composition
If the frame uses multiple joining structures to maintain member orientation, then structural stability is improved, but device complexity increases
Solution Approach 1:
Multiple joining structures are merged into integrated assemblies where movable walls serve dual purposes: maintaining orientation stability and providing latching functionality. The joining structures combine guide surfaces, movable walls, and latching mechanisms into unified components that achieve multiple functions simultaneously.
Solution Approach 2:
The joining structures are designed to self-latch and self-align through the movable wall mechanisms. When members are assembled, the movable walls automatically shift to engage latching features, providing stable orientation without requiring external fastening operations or complex assembly procedures.

AI summary
A frame for receiving a filter element includes: a pair of first members and a pair of second members. The first members may be arranged alternately with the second members in the assembled orientation to establish a plurality of joining structures between adjoining members. Each respective joining structure of the plurality of joining structures maintains the adjoining members oriented substantially about a respective axis. The first members and the second members cooperate to define a volume for effecting the receiving.
