Adjustable Filter Rack Inserts for Variable HVAC Filter Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
HVAC systems are limited in their ability to accommodate filters of varying thicknesses, restricting user flexibility in meeting different heating and cooling requirements while also being inflexible in terms of energy efficiency and cost considerations.
Innovation Solution
The development of adjustable filter racks that include inserts and rotatable guides to accommodate filters of different thicknesses, allowing for easy switching between thinner and thicker filters based on operational needs, thereby enhancing flexibility and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If HVAC units are designed to accommodate filters of only one thickness, then the filter rack structure is simple and fixed, but the consumer's flexibility to use different size filters is limited
Solution Approach 1:
The filter rack is divided into a base and multiple removable inserts. Each insert can be independently positioned or removed to accommodate different filter thicknesses. This segmentation allows the system to adapt to various filter sizes without redesigning the entire rack structure.
Solution Approach 2:
The filter rack transitions from a static, fixed-structure design to a dynamic, adjustable design. Inserts can be moved along the base to different positions, and the rack can be reconfigured for different filter thicknesses, enabling the system to adapt dynamically to changing requirements.
2Reliability
If thicker filters are used, then filtration quality and filtration life are improved, but filter cost increases
Solution Approach 1:
The adjustable filter rack enables dynamic selection of filter thickness based on operational needs. During high-demand periods, thicker filters can be installed for superior filtration and longer life. During low-demand periods, thinner, more economical filters can be used, optimizing the balance between filtration quality and cost.

AI summary
Filter racks are disclosed that are adjustable to accommodate filters of various thicknesses. The filter racks may include an insert that can be positioned within the base of the filter rack in two or more positions to adjust the receiving width of the filter rack. A perforated tab of the insert may be unbent to position the insert within the base at a smaller width, and the tab may be bent to position the insert within the base at a larger width. The insert also may include a divider that can be positioned within the base to reduce the width of the filter rack. Further, a rotating guide may be attached to detents within walls of the filter rack compartment. The guide may be biased at various angles to accommodate filters of different widths.
