Segmented Electric Griddle Surface for Multi-User Cooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric griddles restrict participation in cooking to only one person due to their physical structure, leading to a lack of engagement and increased cooking time, thus failing to facilitate all-participating-type cooking experiences.
Innovation Solution
A heating and cooking apparatus with a cooking surface composed of a high thermal conductivity area and a low thermal conductivity area, separated by heat insulating mechanisms, allowing multiple users to cook simultaneously by placing ingredients directly on the low thermal conductivity area while the high thermal conductivity area is used for heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional electric griddle with a uniform heating surface is used, then the cooking surface can be heated evenly, but only one person can cook at a time, reducing user participation
Solution Approach 1:
The cooking surface is divided into multiple independent heating zones (first heating surface, second heating surface, third heating surface) that can be controlled separately. This segmentation allows multiple users to cook simultaneously on different zones, transforming a single-user device into a multi-user device without requiring complex overall restructuring
Solution Approach 2:
Different regions of the cooking surface are assigned different thermal properties - some areas have high thermal conductivity for rapid heating while others have low thermal conductivity for heat retention. This local differentiation enables various cooking methods to occur simultaneously on different parts of the same device, accommodating multiple users with different cooking needs
2Productivity
If the entire cooking surface is made of high thermal conductivity material, then heating efficiency is improved, but heat loss to the surroundings increases
Solution Approach 1:
The cooking surface uses a composite material structure where high thermal conductivity materials are placed in areas requiring rapid heat transfer (contact with food) while low thermal conductivity materials are used in areas prone to heat loss (edges, sides). This local optimization achieves both efficient heating and reduced energy waste
3Productivity
If the cooking surface is heated to high temperature for efficient cooking, then cooking speed is improved, but the risk of burning and safety hazards increases
Solution Approach 1:
The heating surface is divided into multiple zones with different temperature controls. High-temperature zones are used for rapid cooking when needed, while lower-temperature zones provide safer cooking areas. This segmentation allows the system to achieve high cooking speed in specific areas without exposing the entire surface to high temperatures, reducing burning risks
Solution Approach 2:
Different zones of the cooking surface operate at different temperature parameters simultaneously. By changing the temperature parameter locally rather than uniformly across the entire surface, the system achieves efficient cooking where needed while maintaining safety in other areas

AI summary
A heating and cooking apparatus is provided that can produce a place for all-participating-type cooking. The electric griddle 100 mainly includes an iron plate section 110 having a high thermal conductivity, a glass section 120 having a low thermal conductivity, a heating material 130 as a heat source, a heat insulating mechanism 140, and an outer frame 150. On the glass section 120, it is possible to place dishes and bowls on which food ingredients and the like can be placed in the glass part 120, and to place food ingredients there directly. Thus, it is possible to prevent food ingredients and the like from being placed only in the hands of a specific person, to realize a situation in which many people can easily cook, and to produce a place for all-participating-type cooking.
