Cooking Container Positioning for Level Heating on Inclined Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric cooking devices with a tilting baking sheet lead to uneven cooking due to sauce accumulation and unstable container positioning, which can prevent proper lid closure.
Innovation Solution
An electric cooking device with a configured positioning device that ensures the cooking container is horizontally positioned when in use, preventing sauce accumulation and ensuring stable container placement for proper lid closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cooking plate is inclined relative to the horizontal, then sauces or liquids drain towards the front of the cooking container, but the food inside the cooking container becomes unevenly cooked due to sauce accumulation on one side
Solution Approach 1:
The cooking plate is divided into two functional zones: a first cooking area with an inclined bottom for drainage, and a second cooking area with a horizontal bottom for uniform cooking. This segmentation allows each zone to optimize its function without compromising the other.
Solution Approach 2:
Different regions of the cooking plate are given different geometric properties (inclined vs. horizontal) according to their specific functional requirements. The inclined zone handles liquid drainage while the horizontal zone ensures uniform food cooking, applying local quality to resolve the contradiction.
2Device complexity
If the cooking container is placed on the inclined cooking plate, then the device structure remains simple, but the cooking container becomes unstable and can move, preventing proper lid closure
Solution Approach 1:
A positioning device acts as an intermediary between the inclined cooking plate and the cooking container. This mediator provides stable positioning and support for the container on the inclined surface, ensuring proper lid closure while maintaining the overall simplicity of the device structure.
Solution Approach 2:
The positioning device creates a localized horizontal support surface (equipotential plane) for the cooking container on the otherwise inclined cooking plate, ensuring the container remains stable and properly positioned during cooking operations.
3Volume of moving object
If the cooking container rests directly on the inclined plate bottom, then the device is compact, but sauces accumulate on one side causing uneven cooking of food
Solution Approach 1:
The cooking plate bottom is segmented into two distinct zones: a first inclined zone for sauce drainage and a second horizontal zone for uniform food cooking. This segmentation allows the device to maintain compactness while achieving cooking uniformity through functional zonation.
