Grill Plate Heat-Isolating Frame for Safer Hob Cooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grill and frying plates are limited in their usability across different cooking hobs and often require excessive fat during cooking, posing challenges in secure operation on various types of cooking surfaces.
Innovation Solution
A grill and/or frying plate design featuring a grill section positioned directly above heating elements and a separate frame or warming section, with a silicone gasket and fixation groove to reduce heat transfer and enhance secure handling, allowing for use on induction and non-induction cooking hobs, and equipped with suction cups for additional stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a grill plate is used on a cooking hob, then grilling function is provided, but heat transfer to the frame section causes burning risk during handling
Solution Approach 1:
The grill plate is divided into functionally distinct sections: a grill section positioned over heating elements and a frame section for handling. This segmentation allows different thermal characteristics in different zones, with the frame section designed to minimize heat accumulation while maintaining structural integrity.
Solution Approach 2:
The frame section is specifically designed with reduced heat transfer characteristics compared to the grill section. By creating a transition region with reduced cross-sectional area for heat flow, the frame section maintains lower temperature suitable for safe handling while the grill section operates at high temperature for cooking.
2Reliability
If a grill plate is positioned on a cooking hob, then cooking function is provided, but slipping occurs reducing operational security
Solution Approach 1:
A gasket is introduced as an intermediary element between the grill plate and the cooking hob surface. This gasket provides friction-based grip to prevent slipping during operation, while also serving as a thermal barrier to reduce heat transfer to the frame section, thereby addressing both security and handling safety concerns.
3Adaptability or versatility
If a single-section grill plate is used, then manufacturing is simplified, but multiple cooking functions (grilling, warming, handling) cannot be provided
Solution Approach 1:
The grill plate is segmented into distinct functional zones including a grill section for active cooking over heating elements, a frame section for safe handling with reduced temperature, and potentially a warming section. Each section is optimized for its specific function while maintaining integration within a single plate structure.
Solution Approach 2:
The grill plate is designed to perform multiple functions within a single device: grilling in the grill section, warming in designated areas, and safe handling through the frame section. This multi-functionality is achieved by creating regions with different thermal and structural characteristics within one integrated plate.
4Ease of manufacture
If excessive fat is used for cooking, then cooking process is simplified, but health requirements and cleanliness are compromised
Solution Approach 1:
A grease groove is extracted and positioned at the periphery of the grill plate, creating a dedicated channel for fat and grease collection. This groove system allows excess fat to be drained away from the cooking surface, reducing the amount of fat needed during cooking while maintaining easy cleanup and hygiene.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enables secure operation on various cooking hobs with reduced fat usage, improved heat management, and enhanced safety through targeted heat distribution and secure positioning, ensuring the grill or frying plate can be safely and effectively used on different cooking surfaces.
Implementation Method 1
the gasket supports the grill or frying plate on a worktop which is at least partially surrounding the cooking hob, in particular such that slipping of the grill or frying plate is at least partially prevented
Implementation Method 2
a recess and/or a securing recess and/or a fixation groove are arranged in a region that delimits the grill section from the section different from the grill section, in such a way that the heat transfer from the grill section to the section different from the grill section is reduced
