Dual-Pan Grill Structure for Upper-Lower Pan Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional grills suffer from misalignment issues between the upper and lower pan units, affecting both the functionality and appearance, particularly when transitioning between different positions.
Innovation Solution
The design incorporates a deep pan and a shallow pan that can be detachably mounted on the lower base, with the deep pan abutting the upper pan in one position and the shallow pan in another, ensuring proper alignment and contact with the upper pan's periphery in both positions, with the depth difference matching the vertical movement and misalignment matching the transverse movement of the upper pan.

Engineering Contradiction Analysis
1Device complexity
If a single pan is used in the lower pan unit, then the structure is simple, but misalignment occurs between the upper and lower pans when transitioning between positions
Solution Approach 1:
The lower pan unit is segmented into two separate pans (deep pan and shallow pan) that can be selectively mounted. Each pan is designed with specific depth dimensions to correspond to different positions of the upper pan unit, ensuring proper alignment in each position without requiring a complex single adjustable pan structure.
Solution Approach 2:
The lower pan unit is designed to perform multiple functions by accommodating two different pans for different positions. The pan selecting mechanism allows the same lower pan unit structure to universally support both deep pan (for first position) and shallow pan (for second position), eliminating the need for different lower pan units for each position.
2Adaptability or versatility
If the upper pan unit moves between positions, then operational flexibility is improved, but misalignment between pans occurs affecting appearance
Solution Approach 1:
Each pan (deep pan and shallow pan) is designed with local quality specific to its intended position. The deep pan has greater depth corresponding to the first position, while the shallow pan has lesser depth for the second position. This localized optimization ensures that regardless of which position the upper pan unit is in, the corresponding lower pan provides proper alignment and uniform appearance.
3Volume of moving object
If a deep pan is used for both positions, then the pan capacity is sufficient, but misalignment occurs in the second position where less depth is needed
Solution Approach 1:
The pan capacity requirement is segmented into two separate pans with different depths. The deep pan provides sufficient capacity for the first position, while the shallow pan provides appropriate capacity for the second position. This segmentation allows each pan to be optimally sized for its specific position, preventing misalignment that would occur if a deep pan were used in both positions.

AI summary
A grill comprising an upper pan unit, a lower pan unit and a lever unit. The upper and the lower pan unit have an opposite position relative to each other, which comprises at least a first opposite position and a second opposite position having different distances relative to each other. The upper pan unit comprises an upper pan mounted on an upper base. The lower pan unit comprises a lower base, a deep pan, and a shallow pan. The deep pan can be detachably mounted on the lower base in the first opposite position. The shallow pan can be detachably mounted on the lower base in the second opposite position. The top peripheries of the shallow pan and the deep pan abut against the upper pan. In both positions, the pan of the lower pan unit can abut against the bottom periphery of the upper pan to avoid the misalignment.
