Solution Overview

Problem

Traditional motor mounts for HVAC systems are often configured to align with specific orientations of mounting points, requiring multiple manufacturing variants to accommodate different HVAC system configurations, which increases installation costs and complexity.

Innovation Solution

An adjustable motor mount with adjustable legs that can align with mounting points arranged in various orientations, allowing a single mount to be used across different HVAC systems, and accommodating varying fan motor sizes by adjusting the distance between the motor and the structural support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional motor mounts are configured to align with specific orientations of mounting points, then the mounting structure provides stable support, but multiple manufacturing variants are required to accommodate different HVAC system configurations

Engineering Contradiction:
Improvecompatibility with different mounting point orientationsVSAvoidnumber of motor mount variants
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The motor mount incorporates adjustable legs with threaded adjustment mechanisms that allow the mounting structure to be dynamically reconfigured to match different mounting point orientations. This dynamic adjustability eliminates the need for multiple fixed-configuration mount variants.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The motor mount is designed as a universal mounting structure that can accommodate various HVAC system configurations through its adjustable components. A single universal design replaces multiple specialized variants, each designed for specific mounting point arrangements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of manufacture

If multiple motor mount variants are manufactured to accommodate different HVAC system configurations, then each variant is optimized for its specific configuration, but manufacturing and installation costs increase

Engineering Contradiction:
Improvestandardization of motor mount productionVSAvoidinventory of different mount variants
Core Design Contradiction:
Ease of manufactureVSQuantity of substance

Solution Approach 1:

The motor mount employs a universal design with standardized components that can be used across all HVAC system configurations. This eliminates the need to manufacture and maintain inventory of multiple different mount variants, reducing both manufacturing complexity and inventory requirements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention merges the functionality of multiple specialized motor mount variants into a single adjustable mounting structure. By combining adjustment mechanisms with a standardized base design, it consolidates what would otherwise require separate products for different configurations.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If adjustable legs are incorporated into the motor mount, then adaptability to different mounting point orientations is achieved, but the structural complexity of the mount increases

Engineering Contradiction:
Improveadjustability to mounting point orientationsVSAvoidcomplexity of adjustable mounting structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The motor mount is segmented into distinct functional components: a standardized base structure and separate adjustable legs. This segmentation allows the complex adjustment functionality to be isolated to specific components while maintaining a simple overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adjustable legs incorporate threaded adjustment mechanisms that provide controlled dynamic reconfigurability. This allows the structure to adapt to different orientations while maintaining structural integrity, balancing adjustability with structural simplicity.

Inventive Principle:
Principle #15Dynamics
