Solution Overview

Problem

Existing ventilation hood mounting systems require two people to install, are prone to misalignment due to complex template usage and tedious filler strip installation, and lack efficient single-person operation capabilities.

Innovation Solution

The system employs support brackets with longitudinally spaced support tabs and a locator tab for easy alignment and mounting, allowing the ventilation hood to be hung and secured from these brackets, enabling a single person to mount the hood efficiently by using the brackets' ramped surfaces and potential mechanical fasteners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional template and filler strip mounting methods are used, then alignment can be achieved, but the installation process becomes complex and time-consuming

Engineering Contradiction:
Improvealignment accuracyVSAvoidmounting system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The mounting system is divided into separate functional components: support brackets attached to the cabinet and tabs integrated into the ventilation hood. This segmentation allows each component to be optimized independently and simplifies the overall installation process by eliminating the need for complex templates and filler strips.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support brackets are pre-installed on the cabinet at the correct positions and orientations before the ventilation hood is mounted. This preliminary action establishes the alignment framework in advance, allowing the ventilation hood to be simply attached to the pre-positioned brackets without requiring complex measurement and alignment procedures during installation.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If two people are used to mount the ventilation hood, then proper positioning and securing can be achieved, but the installation requires more labor and coordination

Engineering Contradiction:
Improvemounting reliabilityVSAvoidinstallation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The mounting system is designed to be self-aligning and self-securing. The tabs on the ventilation hood automatically engage with the support brackets, and the system allows a single installer to position and secure the hood without requiring assistance. The design eliminates the need for one person to hold the unit while another fastens it.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If larger holes are drilled to accommodate misalignment, then tolerance is increased, but the mounting precision is reduced

Engineering Contradiction:
Improvealignment toleranceVSAvoidmounting precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The mounting system incorporates adjustable elements that allow for dynamic alignment during installation. The support brackets and tabs are designed with degrees of freedom that enable fine-tuning of positions, allowing the installer to achieve precise alignment without requiring oversized holes or sacrificing mounting precision for tolerance.

Inventive Principle:
Principle #15Dynamics

AI summary

A ventilation hood (70) is mounted to an underside of a cabinet (25) by left and right support brackets (94) each including a main body (95) from which depend at least one support tab (120, 121) or hanger, as well as a locator tab (108). The main body (95) is aligned on the cabinet (25), while the locator tab (108) appropriately spaces the support bracket from an upstanding rear wall (20). Thereafter, the ventilation hood (70) is positioned so the support tabs (120, 121) are received in slots formed in a top panel (153) of the hood and, upon sliding the hood rearward, the hood rides upon ramped or tapered surfaces (144) of the support tabs (120, 121) to position the hood against the cabinet (25) while hanging the hood from the support tabs (120, 121). Thereafter, the support tabs (120, 121) are bent to retain the ventilation hood (70) in an operational position. Employing the distinct aligning, positioning and hanging structure enables a single person to readily mount the ventilation hood (70).
