Recessed Mounting Bracket for Air Mover Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air movers are inefficient and unreliable in exposing surfaces to propelled air, lacking in both efficiency and robustness.
Innovation Solution
The design includes a housing with a recessed mounting bracket that couples the impeller and motor, maintaining alignment with an inlet ring, allowing for maximum airflow and flexibility, and minimizing tolerance between the impeller and inlet ring to enhance efficiency and robustness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional mounting bracket design is used, then the device structure is simpler, but the alignment between impeller inlet and inlet ring cannot be maintained over time, reducing reliability
Solution Approach 1:
The mounting bracket is recessed into the housing through the top portion, creating a nested configuration where the bracket is partially embedded within the housing structure. This nesting provides structural support and maintains alignment between the impeller inlet and inlet ring while integrating smoothly with the overall device architecture.
Solution Approach 2:
The mounting bracket is pre-configured with specific geometric features (chords, arcs, flanges) that establish and maintain the correct alignment between the impeller inlet and inlet ring before operation. This preliminary structural configuration ensures proper alignment is built-in from assembly, preventing misalignment during operation.
2Productivity
If the impeller inlet cross-sectional diameter is maximized, then airflow efficiency increases, but tolerance control between impeller and inlet ring becomes more difficult
Solution Approach 1:
The mounting bracket is pre-configured with specific geometric features (chords, arcs, flanges) that establish and maintain the correct alignment between the impeller inlet and inlet ring before operation. This preliminary structural configuration ensures proper alignment is built-in from assembly, preventing misalignment during operation.
Solution Approach 2:
The patent optimizes the cross-sectional diameter of the impeller inlet as a key parameter to maximize airflow efficiency. By carefully selecting and maintaining this dimensional parameter within controlled tolerances through the mounting bracket design, the system achieves high productivity while managing manufacturing precision requirements.
3Stability of the object's composition
If the mounting bracket is recessed into the housing, then alignment stability is improved, but manufacturing complexity increases
Solution Approach 1:
The mounting bracket is recessed into the housing through the top portion, creating a nested configuration where the bracket is partially embedded within the housing structure. This nesting provides structural support and maintains alignment between the impeller inlet and inlet ring while integrating smoothly with the overall device architecture.
Solution Approach 2:
The mounting bracket is divided into distinct functional segments: top chords for upper support, bottom chords for lower support, vertical chords for lateral stability, and flanges for attachment. This segmentation allows each portion to be optimized for its specific function while simplifying the overall manufacturing process through modular construction.

AI summary
An air mover comprising a housing with a top portion is disclosed. A mounting bracket is recessed into the housing through the top portion of the housing. The mounting bracket comprises a plurality of top chords intersecting at a first portion of an inner web and a plurality of bottom chords intersecting at a second portion of the inner web. The mounting bracket also has a base plate coupled to the plurality of bottom chords. A motor is coupled to the base plate of the mounting bracket. An impeller is coupled to the motor. The air mover further comprises a housing cover that has an inlet ring positioned on the top portion of the housing. The housing cover is coupled to the mounting bracket via the mounting flanges and a portion of the inlet ring protrudes into the impeller inlet inside the housing.
