Integrated Ductwork Frame Assembly to Reduce Pressure Drop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
HVAC systems face challenges with bulky and difficult-to-assemble ductwork components, which affect system performance and increase costs due to their complexity and size.
Innovation Solution
A compact frame assembly is created by directly coupling a louver, a damper, and a screen frame, where the louver is coupled to one side of the screen frame and the damper to the other, reducing the overall size and complexity of the assembly, thereby enhancing operational efficiency and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional separate components are used for damper, louver, and screen frame, then each component can be independently manufactured and assembled, but the overall assembly becomes bulky and complex with increased pressure drop
Solution Approach 1:
The patent combines the damper, louver, and screen frame into a single integrated frame assembly where all three components are mounted on one common frame structure. This merging eliminates the need for multiple separate assemblies, reducing overall complexity and minimizing the distance air travels between components, thereby reducing pressure drop and energy loss.
2Adaptability or versatility
If multiple separate components are used in the ductwork assembly, then each component can be optimized independently, but the number of components increases leading to higher assembly complexity and cost
Solution Approach 1:
The common frame structure serves multiple functions simultaneously: it supports the damper assembly, mounts the louver, holds the screen, and provides the structural framework for the entire assembly. This multi-functionality allows each component to be optimized independently while mounted on a universal frame, reducing the total number of components needed without sacrificing optimization capabilities.
3Reliability
If traditional bulky components are used, then adequate space is provided for each function, but the overall size increases leading to difficult assembly and increased system cost
Solution Approach 1:
The damper, louver, and screen are nested on the same frame structure in a compact arrangement where components are positioned closely together. This nesting approach provides adequate space for each function to operate effectively while maintaining a compact overall footprint, making the assembly easier to install and integrate into HVAC systems without compromising functional adequacy.

AI summary
A frame assembly for an air distribution system includes a damper assembly, a louver assembly, and a screen frame. Air flows through the damper assembly and the louver assembly, where the damper assembly terminates in a first flange and the louver terminates in a second flange. The first flange and the second flange are coupled to one another about a screen frame such that the screen frame is captured by abutting the first flange and the second flange.
