Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking compartment inserts for cooking appliances are limited in usability due to their design, which restricts the variability of heat distribution and functionality, with most having a single integrated heating element and limited configurability.
Innovation Solution
A plate-shaped cooking compartment insert with a separate heating element exposed on one side, housed within a frame that allows for efficient heat emission both upward and downward, and modular design enabling additional components to be easily attached or removed for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single integrated heating element is used in the cooking compartment insert, then the device complexity is reduced, but the adaptability and heat distribution variability are limited
Solution Approach 1:
The heating element is divided into multiple independent heating zones (first heating element, second heating element, third heating element) that can be independently controlled. This segmentation allows different heat distribution patterns (e.g., heating from above only, from below only, or from both sides simultaneously) without increasing overall device complexity, as each segment can be activated based on cooking requirements.
Solution Approach 2:
The cooking compartment insert is designed with movable and adjustable components, including the ability to position the heating element at different heights and angles. This dynamic configuration allows the same heating element to serve multiple functions and achieve various heat distribution patterns, enhancing adaptability without requiring multiple fixed heating elements.
2Weight of moving object
If the base unit is formed as a solid plate, then mechanical stability is improved, but the weight increases and freedom for component arrangement is reduced
Solution Approach 1:
The base unit is designed as a thin-walled hollow structure rather than a solid plate. This shell-like construction significantly reduces weight while maintaining mechanical stability through the structural integrity of the enclosed space. The hollow base unit also provides room for arranging components such as heating elements and insulation materials within its volume.
Solution Approach 2:
The heating element is positioned within the hollow space of the base unit, creating a nested arrangement where the heating element is housed inside the base structure. This nesting approach allows efficient use of space, maintains mechanical stability through the enclosing base structure, and keeps the overall weight low compared to a solid plate design.
3Ease of manufacture
If the heating element is fully enclosed within the base unit, then safety is improved, but heat emission efficiency is reduced
Solution Approach 1:
The base unit is designed with asymmetric opening configurations depending on the heating mode required. For top-heating mode, the base unit has an open top and enclosed bottom; for bottom-heating mode, the configuration is reversed. This asymmetric design allows optimal heat emission in each direction while maintaining protection where needed, reducing energy loss without compromising safety.
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 solution provides increased variability and efficiency in heat distribution, allowing for multiple configurations and enhanced user safety, while maintaining mechanical stability and ease of maintenance.
Implementation Method 1
the heating element is exposed upward and downward in relation to the frame... heat can be emitted both upward and downward. Because this heating element is in fact exposed upward and downward in this basic configuration, this heat emission is particularly efficient.

AI summary
A cooking compartment insert for detachable installation in a cooking compartment of a cooking appliance is formed to be plate-shaped and includes a base unit designed as a frame that is open upward and downward and configured to delimit a free space, and a heating element arranged on the base unit on a side that is remote from an underside of the base unit such that, at least in one region, the heating element is exposed downward. The heating element is arranged in the free space surrounded by the frame, and arranged to be upwardly and downwardly exposed in relation to the frame.
