Air Filter Frame Assembly Actuator Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air handling systems with mechanical clamping mechanisms for high-efficiency filters face risks of human error during filter replacement, which can lead to devastating consequences such as global pandemics due to improper positioning and sealing.
Innovation Solution
A frame assembly with a clamping mechanism featuring an actuator that ensures correct filter positioning by allowing operation only when the filter abuts a stop portion, preventing activation unless the filter is fully inserted, and a spring-loaded clamping device for quick and air-tight sealing, along with a blocking mechanism to prevent door closure if the actuator is not in the closed position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical clamping mechanism is used to secure high efficiency filters, then the filter sealing is improved, but the risk of human error during filter replacement increases
Solution Approach 1:
The actuator element is pre-positioned at a fixed distance from the back member that corresponds exactly to the predetermined filter unit size. This preliminary positioning ensures that the filter must be inserted to the correct depth before the actuator can be operated, preventing improper installation before clamping occurs
Solution Approach 2:
The actuator element acts as an intermediary between the operator and the clamping mechanism. It mediates the operation by physically blocking the actuator's movement path if the filter is not correctly positioned, thereby preventing activation of the clamping mechanism under incorrect conditions
2Device complexity
If the actuator is positioned close to the back member for compact design, then the device complexity is reduced, but the ability to verify filter positioning is compromised
Solution Approach 1:
Instead of adding complexity in the lateral dimension, the solution uses the depth dimension effectively. The actuator element's position in the depth direction (at a specific free distance from the back member) provides the verification function, utilizing the existing spatial dimension without adding structural complexity

AI summary
There is provided a frame assembly 200 adapted for installation in a filter housing of an air handling system. The frame assembly is arranged having a frame 210 which is adapted to receive a filter unit of a predetermined size. The frame assembly further comprises a clamping mechanism 230 arrange for clamping the filter unit. An actuator 231 of the clamping mechanism is arranged at a front member 211 of the frame and is operable between an open and a closed position while activating the clamping mechanism to clamp the filter unit. An actuator element 232 facing a back member 212 of the frame is arranged such that a free distance between the actuator element and the back member during operation of the actuator corresponds to the predetermined filter unit size,thereby enabling operation of the actuator only if an inserted filter unit abuts the back member of the frame.
