Rotatable Grill Plate Leveling for Multi-Position Cooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Countertop grilling appliances often lack versatility in cooking positions, limiting their ability to efficiently cook food items with varying thicknesses and temperature requirements, as they typically have fixed upper and lower grills that do not accommodate different cooking orientations.
Innovation Solution
A multi-function grilling device with a rotatable upper heating plate coupled to a swing arm, allowing it to operate in multiple positions (adjacent face-up, stacked face-up, and face-down) while maintaining parallel alignment with the lower heating plate through a leveling mechanism, enabling flexible cooking configurations and independent temperature control for each plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the upper heating plate is made fixed, then the device structure is simple, but the cooking versatility is limited
Solution Approach 1:
The upper heating plate is transformed from a fixed structure to a dynamic, rotatable structure that can assume multiple positions (adjacent face-up, stacked face-up, and face-down). This dynamic configuration allows the same hardware to serve multiple cooking functions, resolving the contradiction between versatility and structural simplicity.
Solution Approach 2:
The rotatable upper heating plate enables a single device to perform multiple cooking functions by changing its orientation and position. The same heating plate can cook items of different thicknesses and temperature requirements in different positions, achieving multi-functionality without adding multiple separate heating elements.
2Adaptability or versatility
If the upper heating plate is made rotatable, then the cooking versatility is enhanced, but the structural complexity increases
Solution Approach 1:
The swing arm mechanism provides a simple yet effective dynamic connection between the upper and lower heating plates. This single degree of freedom rotation mechanism enables multiple cooking positions without requiring complex multi-axis actuators or sophisticated control systems.
Solution Approach 2:
The swing arm combines multiple functions: it supports the upper heating plate, provides the rotation mechanism, and maintains structural integrity. By merging these functions into a single component, the design avoids the need for separate support structures, actuators, and control mechanisms that would increase complexity.
3Adaptability or versatility
If the upper heating plate rotates about the swing arm, then the cooking positions are flexible, but the parallel alignment is difficult to maintain
Solution Approach 1:
The leveling mechanism dynamically adjusts the upper heating plate's orientation during rotation to maintain parallel alignment with the lower plate. This dynamic compensation ensures that even as the swing arm rotates to different positions, the heating surfaces remain parallel, preserving cooking effectiveness across all positions.
Solution Approach 2:
The leveling mechanism acts as an intermediary between the swing arm's rotation and the upper heating plate's orientation. It mediates the rotational motion to ensure that the heating plate maintains the correct parallel alignment regardless of the swing arm's position, solving the alignment problem without constraining the rotation flexibility.

AI summary
A grilling device includes a housing includes a fixed lower heating plate and a rotatable swing arm disposed at a primary pivot positioned proximate a rear end of the housing. An operable upper heating plate is coupled to the swing arm such that an intermediate portion of the swing arm rotationally engages a central portion of the upper heating plate at a secondary pivot to define an adjacent face-up position, a stacked face-up position and a face-down position. A leveling mechanism maintains the upper heating plate in parallel with the lower heating plate as the swing arm operates about at least a portion of the primary pivot.
