Adjustable Diffuser Assembly for Multi-Size HVAC Duct Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturing multiple diffuser assemblies for HVAC systems to accommodate various duct sizes is costly, complex, and time-consuming, and requires significant inventory and installation complications.
Innovation Solution
An adjustable diffuser assembly with moveable adjustment panels and flanges that can translate along the housing to adjust the inlet port size, allowing it to couple with multiple duct sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple diffuser assemblies are manufactured to accommodate various duct sizes, then adaptability to different duct sizes is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The diffuser assembly is designed with an adjustable inlet port that can accommodate multiple duct sizes using a single device configuration. The inlet port includes movable panels that can be positioned at different locations to match various duct dimensions, eliminating the need for multiple specialized diffuser assemblies for different duct sizes.
Solution Approach 2:
The inlet port incorporates movable adjustment panels that can be dynamically repositioned along the duct interface. These panels are coupled to the housing via sliding mechanisms, allowing the inlet port geometry to be changed based on the specific duct size being connected, thus providing adaptability without requiring multiple fixed configurations.
2Adaptability or versatility
If multiple diffuser assemblies are manufactured to accommodate various duct sizes, then adaptability to different duct sizes is improved, but manufacturing cost and time increase
Solution Approach 1:
A single diffuser assembly design with adjustable inlet port components can serve multiple duct size applications. The housing contains a passage with an inlet port that can be adjusted to match various duct dimensions, eliminating the need to manufacture separate diffuser assemblies for each duct size specification.
Solution Approach 2:
The inlet port is segmented into movable panels that can be independently adjusted. This segmentation allows the same housing structure to accommodate different duct sizes by repositioning the panel components, rather than manufacturing entirely different diffuser assemblies for each application.
3Adaptability or versatility
If multiple diffuser assemblies are manufactured to accommodate various duct sizes, then adaptability to different duct sizes is improved, but inventory requirements and installation complexity increase
Solution Approach 1:
The diffuser assembly is designed as a universal component that can be used across multiple duct size applications. By incorporating an adjustable inlet port, a single inventory item can replace multiple specialized diffuser assemblies, reducing stock requirements while maintaining the ability to accommodate various duct dimensions.

AI summary
A diffuser assembly for a heating, ventilation, and air conditioning (HVAC) system. The diffuser assembly includes a housing having a wall and a passage formed in the wall. The diffuser assembly also includes a first adjustment panel moveably coupled to the wall and having a first flange and a second adjustment panel moveably coupled to the wall and having a second flange. The first flange and the second flange define at least a portion of an inlet port of the diffuser assembly that extends through the passage. The inlet port is configured to fluidly couple to a duct and direct an air flow from the duct into an interior volume of the housing. The first adjustment panel and the second adjustment panel are configured to translate along the wall to adjust a size of the inlet port.
