Adjustable diffuser assembly systems and methods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturing multiple diffuser assemblies for HVAC systems to fit various duct sizes is costly, complex, and time-consuming, increasing storage costs and complicating installation.
Innovation Solution
An adjustable diffuser assembly with moveable adjustment panels and flanges that 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 fit 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 be modified to accommodate multiple duct sizes, transforming a single assembly into a multi-functional device. The inlet port includes adjustment panels that can be repositioned along the housing to create different opening sizes, allowing one universal assembly to replace multiple size-specific assemblies.
Solution Approach 2:
The inlet port is designed with movable adjustment panels that can be dynamically repositioned to change the port size. This dynamic capability allows the diffuser assembly to adapt to different duct sizes without requiring multiple static assemblies, reducing manufacturing complexity while maintaining versatility.
2Adaptability or versatility
If multiple diffuser assemblies are manufactured for different duct sizes, then adaptability is improved, but storage cost increases
Solution Approach 1:
By designing a single diffuser assembly with adjustable inlet port capabilities, the system eliminates the need to manufacture, store, and manage multiple size-specific assemblies. The universal design reduces inventory requirements and storage costs while maintaining the ability to fit various duct sizes through on-site adjustment.
3Adaptability or versatility
If multiple diffuser assemblies are manufactured for different duct sizes, then adaptability is improved, but installation time increases
Solution Approach 1:
The adjustable inlet port with movable panels allows installers to modify the diffuser assembly on-site to match the required duct size, eliminating the need to select from pre-manufactured size-specific assemblies. This dynamic adjustment capability significantly reduces installation time and simplifies the installation process.

AI summary
A diffuser assembly for a heating, ventilation, and air conditioning (HVAC) system 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.
