Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baking trays face issues with non-stick performance, deformation at high temperatures, and weight due to material limitations, particularly with enamelled steel and aluminum trays.
Innovation Solution
A baking tray design featuring a trough-shaped rim with a multi-layer metallic structure, thin temperature-resistant metal sheets, and a unique folding pattern to enhance flexural rigidity and non-stick properties, allowing for high-temperature resistance and light weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional aluminum baking trays are used, then light weight is achieved, but they flex substantially and do not stand firmly on a flat surface
Solution Approach 1:
The rim is segmented into multiple functional zones: a first downward-extending trough wall directly adjoining the supporting area, a trough base, and a second upward-extending trough wall. This segmentation creates a complex three-dimensional profile that provides structural support and prevents flexing while maintaining light weight.
Solution Approach 2:
The rim transitions from a conventional planar or simple flanged structure to a three-dimensional trough-shaped profile with vertical and upward-extending walls. This dimensional change creates greater flexural rigidity and stability without substantially increasing weight, as the structural strength comes from the geometric configuration rather than material quantity.
2Temperature
If enamelled steel sheet is used, then high temperature resistance is achieved, but the coating easily chips off and there is no good non-stick effect
Solution Approach 1:
The patent applies different properties to different parts of the baking tray. The supporting area is provided with a non-stick coating (such as Teflon) for easy release of baked goods, while the rim structure provides the mechanical strength and temperature resistance. This local differentiation allows each zone to perform its specific function optimally without the drawbacks of uniform material properties.
3Stability of the object's composition
If cast aluminum roasting pans are used, then stability is achieved, but they have relatively heavy weight
Solution Approach 1:
The patent uses thin metal sheet material (avoiding heavy cast aluminum) and compensates for the reduced material thickness by creating a rigid structure through the trough-shaped rim profile. The geometric configuration of the rim with its downward and upward extending walls provides the necessary stability and structural integrity that would otherwise require much thicker or heavier material.

Function Achieved in This Case
The solution provides a baking tray that maintains stability and non-stick performance even at high temperatures, is lightweight, and can be used in both orientations without deformation, offering improved efficiency and cost-effectiveness.
Implementation Method 1
designing the rim so that it has a downward extending trough-shaped profile in relation to a top face of the supporting area with a first, downward extending trough wall directly adjoining the supporting area, a trough base and a second, upward extending trough wall opposite the first trough wall
