Solution Overview
Problem
Conventional filter structures for air conditioners are limited in size, leading to mismatch issues when attaching to air inlets of varying dimensions, complicating manufacturing and distribution, as they either cover only part of the inlet or interfere with air outlets.
Innovation Solution
A filter structure with a size-adjustable design featuring a filter layer and adhesive layers, including a strip-shaped contour adhesive layer and strip-shaped partition adhesive layers at predetermined intervals, allowing for cutting to fit different object sizes while maintaining adhesion over the entire circumference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If filter structures are prepared in different sizes for different air conditioner dimensions, then the fit to air inlets is improved, but the product variety and management complexity increase
Solution Approach 1:
The patent applies universality by designing a single filter structure that can serve multiple size requirements. The filter layer is made larger than the air inlet and includes a continuous adhesive layer that allows the filter to be cut to different sizes while maintaining proper attachment. This eliminates the need to manufacture and manage multiple filter size variants for different air conditioner models.
Solution Approach 2:
The patent applies segmentation by allowing the filter layer to be cut into different sizes. The continuous adhesive layer is designed to accommodate cutting at various positions, enabling the single filter structure to be segmented into multiple usable sizes depending on the specific air inlet dimensions, thereby resolving the contradiction between fit precision and product variety.
2Ease of manufacture
If a single size filter structure is used for all air conditioners, then the manufacturing and distribution is simplified, but the filter either covers only part of the air inlet or interferes with air outlets
Solution Approach 1:
The filter structure is designed with universal applicability across different air conditioner sizes. The filter layer dimensions are set to be larger than the air inlet, and the continuous adhesive layer allows the filter to be adapted to different sizes through cutting, enabling a single design to serve multiple applications without compromising fit precision.
Solution Approach 2:
The patent applies dynamics by making the filter structure adaptable rather than fixed. The continuous adhesive layer is designed to accommodate cutting at various positions, allowing the filter size to be dynamically adjusted to match different air inlet dimensions, thus maintaining both manufacturing simplicity and fit precision.
3Length of stationary object
If the filter layer is cut to fit smaller air inlets, then the interference with air outlets is avoided, but the adhesion may be compromised without proper adhesive layer design
Solution Approach 1:
The patent applies preliminary action by pre-configuring the adhesive layer as a continuous strip that extends across the entire filter layer. This preliminary adhesive configuration ensures that regardless of where the filter is cut to fit different air inlet sizes, the adhesive layer will always provide sufficient continuous attachment surface to maintain reliable adhesion to the air inlet.

AI summary
Filter structure including filter layer having air permeability to filter gas passing therethrough and adhesive layer of adhesive on at least part of one surface of the filter layer. A size of the filter layer is appropriate for the dimension of a first object, in case of attachment to a second object having a dimension smaller than that of the first object, the filter layer configured to be cut at a predetermined position, in which the adhesive layer includes a strip contour adhesive layer continuous along a contour of the filter layer and a strip partition adhesive layer continuous along at least part of the contour adhesive layer, at a predetermined interval therefrom, within the contour adhesive layer, a cut region being set between the contour adhesive layer and the partition adhesive layer so that the filter layer is cut to a size appropriate for a size of the second object.
