Oven appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oven appliance assembly processes are ergonomically challenging due to the requirement of multiple parts and complex steps, particularly with the use of hinge pins for connecting the maintop to the cabinet.
Innovation Solution
The oven appliance design incorporates embosses on the cabinet to constrain the maintop during assembly, allowing it to be slid onto the cabinet and aligned, eliminating the need for hinge pins and reducing the part count by using first and second embosses to prevent side-to-side movement, thus simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hinge pins are used to connect the maintop to the cabinet, then the maintop can be pivotally connected and rotated for installation, but the assembly process becomes complex and ergonomically challenging
Solution Approach 1:
The patent removes hinge pins from the assembly process entirely. Instead of using separate hinge pin components, the maintop is directly attached to the cabinet through a sliding insertion process, eliminating the need for pivotal connection mechanisms and reducing assembly steps
Solution Approach 2:
The patent combines the connection function that was previously performed by separate hinge pins into an integrated sliding fit between the maintop and cabinet. The mounting structure merges the positioning and securing functions into a single operational step
2Reliability
If multiple parts and steps are used for assembly, then the maintop can be securely connected to the cabinet, but the part count increases and assembly becomes more difficult
Solution Approach 1:
The patent extracts and removes multiple assembly components including hinge pins, separate fasteners, and alignment fixtures. The design achieves secure connection through a simplified sliding fit mechanism that requires fewer parts while maintaining structural integrity
Solution Approach 2:
The sliding mounting structure performs multiple functions simultaneously: it provides alignment, positioning, and secure connection in a single integrated mechanism, eliminating the need for separate components for each function
3Ease of manufacture
If the maintop is pivotally connected with hinge pins, then the maintop can be rotated up for wiring installation, but the assembly process requires propping and holding the maintop in place
Solution Approach 1:
The patent removes the pivotal connection mechanism that required the maintop to be propped or held during assembly. The direct sliding attachment allows the maintop to be securely positioned without requiring external support or holding devices
4Manufacturing precision
If conventional assembly methods are used, then the maintop can be connected to the cabinet, but the alignment process requires additional steps and time
Solution Approach 1:
The maintop and cabinet are designed with pre-formed complementary geometries that provide automatic alignment during the sliding insertion process. The mounting structure includes built-in alignment features that guide the maintop into the correct position without requiring separate alignment steps

AI summary
An oven appliance includes a cabinet extending between a top portion and a bottom portion along a vertical direction and extending between a left side and a right side along a lateral direction. The vertical direction and the lateral direction are mutually perpendicular. The oven appliance also includes a maintop having a heating element positioned within the maintop. The maintop is fixedly mounted to the top portion of the cabinet. The maintop is constrained against movement along the lateral direction by a first emboss at the left side of the cabinet and a second emboss at the right side of the cabinet.
