Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing scroll compressor mounting bases lack sufficient structural strength and integrity to securely support the compressor and withstand operational vibrations, leading to potential buckling and instability.

Innovation Solution

A mounting base with at least two tracks and one or more support ribs, formed into a unitary metal component, provides enhanced structural strength by projecting transversely between the tracks and extending over mounting holes, offering a U-shaped cross-section for increased rigidity and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a mounting base is used to support the scroll compressor, then the compressor can be mounted on rails, but the mounting base lacks sufficient structural strength and integrity to prevent buckling under operational vibrations

Engineering Contradiction:

Improvestructural strengthVSAvoidstability under vibration

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The mounting base is divided into multiple functional segments: a body portion, downwardly depending tracks, and transverse support ribs. This segmentation allows each component to perform its specific function optimally while collectively providing the necessary structural strength and vibration resistance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Support ribs are strategically positioned at critical locations on the mounting base where additional strength is needed to prevent buckling. The ribs extend transversely between tracks and over mounting holes, providing localized reinforcement exactly where the structure is most vulnerable to vibration-induced failure.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If the mounting base is designed with tracks for rail mounting, then the compressor can be securely mounted, but the base structure becomes prone to buckling under weight and vibration loads

Engineering Contradiction:

Improvemounting capabilityVSAvoidresistance to buckling

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The support ribs extend in a transverse direction between the tracks, adding a third dimension of structural support. This transverse reinforcement creates a rigid framework that resists buckling forces from multiple directions while maintaining the track mounting capability.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If the mounting base uses a simple plate structure, then manufacturing is easy, but the structure lacks sufficient rigidity to withstand operational vibrations

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidrigidity under vibration

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The support ribs are merged with the mounting base body as an integral structure rather than separate components. This unified design maintains manufacturing simplicity while significantly increasing rigidity, as the ribs and body work together as a single load-bearing structure.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A scroll compressor assembly includes a mounting base with a pair of support ribs formed into the mounting base, for structurally strengthening the support provided by the mounting base. The mounting base may either support the scroll compressor housing as a separate component part or may integrally form part of the scroll compressor housing. The mounting base has at least two tracks for rail mounting of the scroll compressor assembly and typically includes holes for fasteners.
