Solution Overview

Problem

Conventional HVAC systems face difficulties in acutely adjusting the position of the motor relative to the blower, making it challenging to effectively install, operate, and maintain the belt-driven rotational motion, which affects the efficient operation of the blower.

Innovation Solution

An adjustable motor mount system is introduced, featuring a first bracket that moves along a mounting rail and a second bracket that adjusts transversely to the first bracket, allowing the motor to be positioned in multiple directions relative to the blower, facilitating alignment and tensioning of the belt for efficient rotational motion transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed motor mount is used, then the structure is simple and stable, but the motor position cannot be adjusted relative to the blower

Engineering Contradiction:
Improvemotor position adjustabilityVSAvoidmounting bracket structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The motor mount is divided into multiple independent mounting brackets (first mounting bracket, second mounting bracket, third mounting bracket) that can be adjusted separately along different axes. Each bracket handles a specific directional adjustment, allowing the motor to be positioned precisely in three-dimensional space relative to the blower while keeping each individual bracket relatively simple in structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting brackets are designed with adjustable features that allow dynamic repositioning of the motor along the mounting rail and perpendicular to it. The brackets can be moved to different positions and secured at desired locations, transforming a static fixed mount into a dynamic adjustable system that adapts to different installation requirements.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the motor position is fixed, then the installation is simple, but the belt alignment and tensioning are difficult

Engineering Contradiction:
Improvebelt installation and tensioningVSAvoidadjustable mounting mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The adjustment mechanism is segmented into multiple independent brackets that can be adjusted separately along different axes. This allows the installer to first position the motor along the mounting rail, then make perpendicular adjustments for precise belt alignment, and finally tension the belt independently of the positioning mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting brackets provide dynamic adjustment capability during installation and maintenance, allowing the motor to be repositioned easily to achieve proper belt alignment and tensioning without requiring complex realignment procedures or specialized tools.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If a single-axis adjustment mechanism is used, then the structure is simple, but the motor cannot be precisely positioned in multiple directions

Engineering Contradiction:
Improvemotor positioning precisionVSAvoidmulti-axis mounting bracket
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The positioning system is segmented into multiple brackets responsible for different adjustment axes. The first mounting bracket handles adjustment along the mounting rail, the second mounting bracket handles perpendicular adjustment, and the third mounting bracket provides additional positioning. This segmentation allows precise control of motor position in three-dimensional space while keeping each bracket's structure relatively simple and manageable.

Inventive Principle:
Principle #1Segmentation

AI summary

A heating ventilation, and/or air conditioning (HVAC) system includes a support structure having a mounting rail, a first mounting bracket coupled to the mounting rail and configured to be adjustably positioned along a first axis of the mounting rail, and a second mounting bracket directly coupled to the first mounting bracket. The second mounting bracket is configured to support a fan motor mounted thereto, the second mounting bracket is configured to be adjustably positioned along a second axis of the first mounting bracket, and the second axis of the first mounting bracket is transverse to the first axis of the mounting rail.
