Over-the-Range Appliance Latch Mounting for Single-Person Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of over-the-range cooking appliances, particularly microwave cooking appliances, is a lengthy process that often requires multiple individuals and involves drilling numerous holes into cabinetry, complicating the mounting process due to the need for precise alignment of mounting screws.
Innovation Solution
An over-the-range cooking appliance design that allows for single-person installation, featuring a wall bracket and a cabinet bracket with cooperating latch members that latch together when the appliance is tilted upward, simplifying the mounting process by eliminating the need for simultaneous holding and screw alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mounting methods are used with multiple individuals and drilling many holes, then secure mounting is achieved, but installation time and complexity increase
Solution Approach 1:
The mounting system is divided into separate components: a wall-mounted bracket that provides primary support and a cabinet bracket with latch members that provides secondary securing. This segmentation allows each component to perform its function independently, eliminating the need for multiple people to hold the appliance while drilling, thus reducing installation time while maintaining secure mounting.
Solution Approach 2:
The wall bracket is pre-installed on the wall before the appliance is mounted. This preliminary action provides a stable foundation that supports the appliance during the mounting process, eliminating the need for one person to hold the appliance while another drills, thereby reducing installation time without compromising mounting security.
2Manufacturing precision
If traditional mounting methods are used with multiple individuals, then proper alignment is achieved, but device complexity and labor requirements increase
Solution Approach 1:
The latch members are designed to automatically engage with corresponding receptacles on the wall bracket when the appliance is positioned correctly. This self-latching mechanism eliminates the need for one person to hold the appliance in alignment while another inserts and tightens screws, simplifying the mounting process while ensuring proper alignment through the self-aligning nature of the latch-receptacle interface.
3Reliability
If multiple mounting holes are drilled into cabinetry, then secure attachment is achieved, but damage to cabinetry and installation complexity increase
Solution Approach 1:
The mounting system extracts the drilling function from the cabinetry by providing a dedicated wall-mounted bracket that bears the full weight and mounting load. This eliminates the need to drill multiple holes into the cabinetry itself, reducing potential damage to the cabinetry and simplifying installation since the bracket can be mounted on the wall independently of the cabinet structure.

AI summary
An over-the-range cooking appliance for mounting to an underside of a wall cabinet, where the cooking appliance includes: an enclosure with a cooking cavity for food and where the enclosure includes at least a rear-facing side and a top-facing side; a wall bracket configured to be secured to the wall near the wall cabinet and configured to support the enclosure; and a cabinet bracket to support the enclosure from the underside of the wall cabinet. The cabinet bracket includes a first and second cooperating latch member, where the first cooperating latch member is mounted on the underside of the cabinet and the second cooperating latch member is mounted on the top-facing side of the enclosure. The cooperating latch members are respectively configured to latch to one another when the enclosure is supported on the wall bracket proximate the bottom of the rear-facing side thereof and tilted upwardly.
