Blower Bracket Assembly for HVAC Vibration Isolation and Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blower mounting systems in HVAC systems experience vibrational forces that cause interference and performance degradation due to uncontrolled movement of the blower, leading to noise and reduced performance over time.
Innovation Solution
A bracket assembly with a base panel, mounting flanges, and an alignment flange, combined with a spring and damper assembly, limits the blower's movement along certain axes while allowing axial movement, thereby blocking interference with other HVAC components and attenuating vibrational forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blower is rigidly mounted to the HVAC unit, then the blower remains stable and does not move, but vibrational forces are transferred to other HVAC components causing performance degradation
Solution Approach 1:
The patent introduces a mounting bracket assembly as an intermediary component between the blower and the HVAC unit. This bracket includes a base panel with mounting flanges that provide a dedicated interface, and an alignment flange with an aperture that receives a bolt to limit blower movement. The bracket absorbs and isolates vibrational forces, preventing their transfer to other HVAC components while maintaining blower stability during operation.
2Object-generated harmful factors
If the blower is allowed to move freely, then vibrational forces are isolated from other components, but the blower interferes with other HVAC components causing performance degradation
Solution Approach 1:
The patent implements a dynamic mounting system where the blower is not completely fixed but rather constrained within specific limits. The alignment flange with its aperture allows controlled movement in certain directions while restricting movement in other directions. This dynamic constraint enables the blower to absorb vibrational forces through limited movement while preventing interference with other HVAC components by maintaining position stability within acceptable boundaries.
3Device complexity
If conventional rigid mounting is used, then the structure is simple, but noise and performance degradation occur over time
Solution Approach 1:
The patent segments the mounting system into distinct functional components: a base panel with mounting flanges for structural attachment, an alignment flange with aperture for movement control, and a bolt for securing the blower. This segmentation allows each component to perform its specific function - the base panel provides structural support, the alignment flange controls movement and isolates vibrations, and the bolt secures the assembly. This modular approach reduces noise and prevents performance degradation while maintaining reasonable structural simplicity.

Function Achieved in This Case
The solution effectively reduces interference and noise, maintains blower performance, and prevents performance degradation by controlling the range of motion and absorbing vibrational energy, ensuring stable operation and reduced wear.
Implementation Method 1
a spring assembly configured to be disposed between a first rail of a blower mounting skid supporting the blower and a second rail of the HVAC unit
Implementation Method 2
the alignment flange has an alignment aperture configured to receive a bolt engaged with the first rail. The alignment aperture is configured to restrict lateral movement of the bolt and enable axial movement of the bolt

AI summary
A blower mounting assembly of a heating, ventilation, and/or air conditioning (HVAC) system includes a bracket assembly including a base panel, a plurality of mounting flanges extending from the base panel, and an alignment flange extending from and transverse to the base panel. The blower mounting assembly includes a first mounting aperture extending through the base panel in a first direction and includes second mounting apertures extending through the plurality of mounting flanges in a second direction transverse to the first direction. The blower mounting assembly includes a bolt configured to extend through and slidably engage with an aperture of the alignment flange and a blower mounting skid such that the bolt limits movement of the blower mounting skid relative to the bracket assembly. The aperture of the alignment flange extends through the alignment flange in a third direction transverse to the first mounting aperture and the second mounting apertures.
