Filter Sheet With Bendable Ears for Secure Grille Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filters for air vents and ventilation systems often detach easily from their bonding objects due to small contact areas, necessitating the use of additional fasteners like hook and loop systems, which are time-consuming to install.
Innovation Solution
A filter sheet design featuring a filter body with integrally connected ears that can be bent to secure against the side surface of the bonding object, eliminating the need for separate fasteners by enhancing attachment strength through repulsion-reducing features and adhesive layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a filter is bonded to the front surface of a grille with louver or mesh shape, then the filter can be attached without additional fasteners, but the bonded area is small and the filter is likely to separate from the grille
Solution Approach 1:
The filter extends from the front surface of the grille into the gap between the grille and the wall by forming a rear surface that contacts the wall surface. This transitions the attachment from a single-surface bond to a multi-dimensional attachment involving both the front surface and the wall behind the grille, significantly increasing the effective bonded area and preventing filter separation.
2Reliability
If a hook and loop fastener is used together with the filter, then the filter retention is improved, but the installation time is increased
Solution Approach 1:
The invention extracts and eliminates the need for separate hook and loop fasteners by integrating the attachment function directly into the filter structure. The filter's rear surface itself provides the bonding interface with the wall, removing the requirement for additional fastening components and reducing installation time while maintaining reliable retention.
3Adaptability or versatility
If the filter shape does not coincide with the grille shape, then the filter can be used with different grille types, but the filter must be cut and modified
Solution Approach 1:
The filter is designed with a front surface that can be customized to match specific grille shapes (circular, rectangular, hood type, etc.), while the rear surface maintains a larger area than the front surface to ensure sufficient bonding area regardless of the grille shape. This allows the filter to be optimally adapted to different grille types without requiring cutting or modification, as the rear surface area compensates for any shape variations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The filter sheet provides stable attachment to various bonding objects without additional fasteners, ensuring the filter remains securely in place, reducing installation time and material waste.
Implementation Method 1
the filter body has, on a back surface opposite to a front surface, an adhesive layer
Implementation Method 2
the ear or each of the ears preferably includes, at a boundary between the filter body and the ear, a repulsion reducing portion for reducing elastic repulsion of the material of the filter when the ear is bent relative to the filter body

AI summary
A filter bondable to a grille is provided. The filter is fixable alone to the grille so as not to separate therefrom without using another element such as a hook and loop fastener. The filter is constituted by a filter body and ears integrally connected to the outer edge of the filter body. The filter is bondable to the grille by bringing the filer body into abutment with the front surface of the grille, and bending the ears relative to the filter body until the ears abut against the side surface of the grille. By forming the ears at the filter, and bringing the ears into abutment with the side surface of the grille so as to be bonded thereto, it is possible to increase the attachment strength of the filter relative to the grille, compared to conventional filters each constituted by only a filter body.
