Elastic Support-Ring Filter Structure for Compact Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The packaging size and transportation costs of filtering devices, such as filter screens or filter elements, are increased due to their hollow cylindrical structure, leading to inefficient use of space and waste of transportation resources.
Innovation Solution
A filtering device with a filter layer enclosed in a cylindrical structure, supported by a support frame with elastic connection portions that allow deformation and restoration, enabling a folding structure for packaging and returning to the original shape for use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the filtering device uses a hollow cylindrical structure to maximize filtering area, then the filtering area is improved, but the packaging size and transportation cost increase
Solution Approach 1:
The support ring is divided into multiple support ring segments that can be relatively moved with respect to each other. This segmentation allows the cylindrical structure to be compressed into a smaller packaging size while maintaining the full filtering area when deployed, as the segments can be arranged closely during packaging and form the complete cylinder structure during use.
Solution Approach 2:
The support ring segments are connected through elastic connection portions that enable dynamic transformation between expanded and compressed states. The elastic connection portions allow the structure to transition from a compact packaged form to a fully expanded cylindrical form, resolving the contradiction between packaging size and filtering area.
2Area of stationary object
If the filtering device uses a hollow cylindrical structure, then the filtering area is maximized, but the transportation cost increases
Solution Approach 1:
By segmenting the support ring into movable segments, the device can be compacted for transportation, reducing the volume that needs to be transported and thereby lowering transportation costs while preserving the full filtering area for use.
Solution Approach 2:
The support ring segments can be nested or arranged in a compact configuration during packaging, similar to nested dolls, allowing the large cylindrical structure to be contained in a smaller packaging volume, thus reducing transportation cost while maintaining the full filtering area when deployed.
3Stability of the object's composition
If the support ring segments are connected rigidly, then the structural stability is improved, but the ability to deform for packaging is reduced
Solution Approach 1:
The elastic connection portions provide dynamic connectivity between support ring segments, allowing the structure to be stable in its deployed cylindrical form while enabling deformation and compression for packaging. The elasticity provides both stability during use and adaptability during packaging.
Solution Approach 2:
The elastic connection portions act as flexible elements connecting the rigid support ring segments, allowing the overall structure to be flexible enough for packaging while maintaining structural integrity when deployed. The flexible connection portions enable deformation without compromising the stability of the complete structure.

AI summary
A filtering device, including: a filter layer, where the filter layer is enclosed into a cylindrical structure; a support frame includes at least one support ring arranged at the end of the cylindrical structure, the support ring is provided with a plurality of elastic connection portions and a plurality of support ring segments, and two adjacent support ring segments are connected by using one elastic connection portion; the elastic connection portion is capable of being elastically deformed when subjected to an external force and capable of restoring by using its own elastic force; when the elastic connection portion is elastically deformed, an angle at which the end portions of the two adjacent support ring segments are connected changes, which drives a shape of the filter layer to change synchronously; when the elastic connection portion restores, the angle changes, which drives the filter layer to restore to an original shape.
