Solution Overview

Problem

Existing appliance mounting systems fail to securely and efficiently integrate refrigerators into cabinet structures without compromising the vacuum insulation, leading to potential loss of cold temperatures and reduced insulation efficiency.

Innovation Solution

A side-mounting bracket system comprising a mounting bracket and a trim member, where the mounting bracket is welded to the refrigerator's sidewall and the trim member is mounted to the bracket using aligned apertures and fasteners, ensuring secure attachment without piercing the external wrapper and maintaining the vacuum seal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fasteners are used to secure the refrigerator to the cabinet structure, then the refrigerator is firmly fixed, but the vacuum insulation may be compromised

Engineering Contradiction:
Improvefixing securityVSAvoidvacuum insulation loss
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

A mounting bracket system serves as an intermediary component between the refrigerator and cabinet structure. The bracket is welded to the refrigerator's external wrapper at specific mounting points, providing secure attachment without requiring fasteners that would pierce the vacuum seal. This mediator allows mechanical fixation while preserving the vacuum insulation integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The mounting system is segmented into discrete mounting points distributed around the refrigerator perimeter. Instead of a continuous attachment method that would compromise the vacuum seal, the system uses localized welding at specific segments or zones, allowing the majority of the external wrapper to remain intact and maintain vacuum insulation.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the refrigerator is securely mounted to the cabinet structure, then stability is improved, but the vacuum seal may be compromised

Engineering Contradiction:
Improvemounting stabilityVSAvoidvacuum seal integrity
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The mounting bracket acts as a mediator that transfers mechanical loads between the refrigerator and cabinet structure without compromising the vacuum seal. The bracket is welded to the external wrapper at mounting points positioned away from critical vacuum seal areas, providing structural stability while preserving seal integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The external wrapper has different local properties: regions designated for mounting points have enhanced structural characteristics to accommodate welding, while the majority of the surface maintains optimized vacuum seal properties. This local differentiation allows stable mounting without compromising overall seal integrity.

Inventive Principle:
Principle #3Local quality

AI summary

A bracket system (82) for coupling an appliance (10) to a cabinet structure (60) includes a mounting bracket (90) having an inner wall (94) spaced-apart from an outer wall (96) and a plurality of apertures (102) provided through the outer wall (96). The inner wall (94) couples to the outer surface (47) of the appliance (10) in assembly. A trim member (92) includes first and second mounting portions (126, 128) and an abutment portion (130) disposed therebetween. The first and second mounting portions (126, 128) each include a plurality of apertures (132, 142). The first mounting portion (126) abuts the outer wall of the mounting bracket (90), and the respective apertures (132, 102) disposed therebetween are then aligned. The second mounting portion (128) is configured to abut an inner surface (67) of the cabinet structure (60) for mounting thereto via the plurality of apertures (142) thereof.
