HVAC Filter Locking Assembly for Tool-Free Secure Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HVAC filter security systems require excessive manufacturing time and complex mechanisms, making them time-consuming and costly to assemble, and often necessitate the use of tools for filter installation and removal.
Innovation Solution
A filter housing system with a connecting channel and a locking system that secures the filter via rotation of a screw, allowing for tool-free installation and removal, and manufacturing without welding or complex machinery, using riveting and v-grooving to reduce production costs and operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex filter security systems are used, then filter retention is secure, but manufacturing time and assembly complexity increase excessively
Solution Approach 1:
The filter security system is divided into separate modular components: connecting channels integrated into the enclosure, discrete locking systems with brackets and fasteners, and filter frames with attachment features. This segmentation allows each component to be manufactured independently using simple processes and assembled through straightforward connection, reducing overall system complexity while maintaining secure filter retention.
2Reliability
If complex filter security systems are used, then filter retention is secure, but manufacturing and assembly time increase excessively
Solution Approach 1:
The connecting channels are pre-integrated into the enclosure during enclosure manufacturing, and the locking systems are pre-assembled with brackets and fasteners before final installation. This preliminary preparation eliminates the need for complex on-site assembly operations, significantly reducing manufacturing and assembly time while ensuring secure filter retention through pre-configured connection points.
3Reliability
If traditional filter security mechanisms are used, then filter retention is achieved, but tool-free installation and removal are not enabled
Solution Approach 1:
The locking systems incorporate self-contained fastening mechanisms with integrated fasteners that can be manually operated without external tools. The brackets and locking components are designed to engage and disengage through simple manual manipulation, enabling users to install and remove filters without requiring specialized tools while maintaining secure retention during operation.
