Filter securement assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baffles in exhaust hoods require regular cleaning to prevent grease buildup, which is time-consuming, labor-intensive, and poses a fire hazard. Additionally, they are aesthetically undesirable and can be dangerous to remove and reinstall.
Innovation Solution
A filter securement assembly designed to replace traditional baffles, which includes a main panel with retainment surfaces and lips to securely hold filter media. This assembly prevents grease buildup on exhaust system components, is easy to install, and allows for simple replacement of filter media.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional baffles are used in exhaust hoods, then grease can be blocked from entering the exhaust system, but grease buildup occurs on the baffles requiring regular cleaning
Solution Approach 1:
The patent extracts the filtering function from fixed baffles and transfers it to removable filter media. The filter media captures grease particles while the main panel and exhaust hood remain clean, eliminating the need to clean the exhaust system components while maintaining grease blocking functionality.
Solution Approach 2:
The filter media is designed to be disposable or easily replaceable. When the filter media becomes saturated with grease, it is removed and replaced with a clean filter, transferring the cleaning task from the exhaust system to the filter media itself, which can be handled more safely and conveniently.
2Reliability
If traditional baffle systems are used, then exhaust system protection is provided, but they pose fire hazards and are aesthetically undesirable
Solution Approach 1:
The filter media is designed as a disposable or easily replaceable component that can be made from fire-resistant materials. This eliminates fire hazards associated with cleaning hot baffles, as the filter media can be replaced without exposing workers to hot surfaces, while maintaining exhaust system protection.
3Object-affected harmful factors
If conventional baffles are installed, then grease filtration is achieved, but installation and maintenance are labor-intensive and time-consuming
Solution Approach 1:
The system is segmented into three main components: the exhaust hood, the removable filter media, and the main panel. This segmentation allows the filter media to be independently removed and replaced without disassembling the entire exhaust system, significantly reducing maintenance time and labor requirements while maintaining effective grease filtration.
4Reliability
If traditional baffle systems are used, then exhaust protection is provided, but they are dangerous to remove and reinstall
Solution Approach 1:
The protective filtering function is extracted from the permanent exhaust hood structure and placed in a removable filter media. This allows the filter to be removed and replaced without working inside the hot exhaust hood, eliminating the safety hazards associated with handling hot surfaces during maintenance while maintaining exhaust protection.

AI summary
Filter assemblies are described. In particular, a filter securement assembly for receiving and retaining a filter media in an exhaust hood includes a main panel defining a first end and an opposed second end, a first retainment surface adjacent the first end of the main panel, a first retainment lip adjacent the first retainment surface, a second retainment surface adjacent the second end of the main panel and a second retainment lip adjacent the second retainment surface.
