Gas Cooktop Orifice Holder Mounting for Anti-Rotation Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mounting arrangements for gas orifice holders in gas cooking appliances are labor-intensive and lack a reliable anti-rotation feature, leading to improper alignment of gas burner components during assembly.
Innovation Solution
A non-rotational mounting mechanism using interengaging polygonal structures, such as a key-shaped peg and hole combination, ensures the orifice holder is securely attached to a support member in a single predetermined orientation, preventing relative rotation and ensuring proper alignment of gas burner components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical fasteners are used to mount the orifice holder, then the mounting is reliable, but the assembly process is labor-intensive and time-consuming
Solution Approach 1:
The patent combines the anti-rotation feature and mounting function into a single integrated mechanism. The polygonal connecting structure serves dual purposes: it prevents rotation of the orifice holder while simultaneously providing the mounting attachment point, eliminating the need for separate anti-rotation components and fasteners.
Solution Approach 2:
The polygonal connecting structure is designed to be self-aligning and self-locking. The geometric shape of the polygonal peg and hole combination automatically ensures proper orientation and prevents rotation without requiring additional adjustment or tightening operations by the assembler.
2Device complexity
If no anti-rotation feature is provided, then the mounting structure is simpler, but the gas burner components become misaligned during assembly
Solution Approach 1:
The patent employs asymmetric polygonal shapes (such as triangular or rectangular pegs) that can only fit into corresponding holes in specific orientations. This asymmetric geometry inherently guides the orifice holder into the correct aligned position during assembly and prevents any rotational movement that would cause misalignment of gas burner components.
3Reliability
If traditional anti-rotation arrangements are used, then rotation is prevented, but the mass of the orifice holder increases
Solution Approach 1:
The anti-rotation function is merged into the existing mounting structure through the polygonal connecting elements. Rather than adding separate anti-rotation brackets, pins, or locking mechanisms that would increase mass, the geometric shape of the polygonal peg and hole combination itself provides the anti-rotation capability as an inherent feature of the mounting structure.

AI summary
A compact non-rotational mounting feature or mechanism is employed for mounting an orifice holder to a support member below a cooktop of a gas cooking appliance. More specifically, the holder and support member include interengaging polygonal structure, such as a key-shaped anti-rotational peg and hole combination, allowing the holder to be initially mated with the support member in a manner which prevents relative rotation and assuring that the holder is appropriately positioned for proper alignment of various gas burner components, such as an orifice, a gas line, electrode, flame spreader and other burner related structure. Upon exacting the positioning of the holder relative to the support member, the holder to fixed in position by a mechanical fastener.
