Infrared heating cooker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infrared heating cookers only allow adjustment of the height of the cooking pan, preventing the placement of a second cooking pan on top, limiting the variety of dishes that can be cooked.
Innovation Solution
An infrared heating cooker design featuring a first cooking pan with a separation preventing unit along its edge, allowing a second cooking pan to be detachably mounted on top, receiving heat from both the upper heating element and the first cooking pan, enabling cooking of food on multiple pan configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only the height of the cooking pan is adjusted, then the structure remains simple, but another cooking pan cannot be placed on top limiting cooking variety
Solution Approach 1:
The patent implements a nested structure where a second cooking pan is placed on top of the first cooking pan. The first cooking pan includes a receiving groove that accommodates the second cooking pan, allowing one pan to be nested within another. This enables multiple cooking pans to be stacked vertically, increasing cooking variety without significantly increasing device complexity.
Solution Approach 2:
The patent transitions from horizontal pan arrangement to vertical stacking by utilizing the vertical dimension. By adding a receiving groove in the vertical direction and allowing height adjustment of the first cooking pan, the system enables placement of a second pan on top, effectively using three-dimensional space to increase versatility.
2Adaptability or versatility
If a second cooking pan is placed on the first cooking pan, then cooking versatility improves, but the risk of separation increases
Solution Approach 1:
The patent divides the pan assembly into distinct segments: the first cooking pan with a receiving groove and the second cooking pan with a protrusion. This segmentation allows for easy assembly and disassembly while maintaining stability during use. The separation preventing unit is integrated into the first pan's structure, creating modular components that work together.
Solution Approach 2:
The patent introduces a separation preventing unit as an intermediary mechanism between the two cooking pans. This unit includes a protrusion on the second pan that fits into the receiving groove of the first pan, creating a mechanical interlock that prevents separation while allowing controlled assembly and disassembly.
3Use of energy by moving object
If the first cooking pan receives heat directly, then heating efficiency is high, but moisture loss may occur
Solution Approach 1:
The nested pan configuration allows the second cooking pan to be placed on top of the first pan, creating a layered heating structure. The first pan receives direct heat from the heating element, while the second pan receives heat through conduction from the first pan. This nested arrangement improves moisture retention by reducing direct exposure to intense heat.
Solution Approach 2:
The first cooking pan acts as an intermediary heat transfer medium between the heating element and the second cooking pan. Heat is transferred from the heating element to the first pan, then conducted to the second pan, providing more gentle and distributed heating that reduces moisture loss while maintaining heating efficiency.
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
Enables cooking with various types of food on both the first and second cooking pans, including box-shaped, convex-shaped, hemispherical, and concave-shaped pans, allowing for flexible cooking options and preventing moisture loss during cooking.
Implementation Method 1
Radiation heat is transmitted through a process of emitting electromagnetic energy from the surface of a certain heating element. Radiation heat is emitted at the speed of light even in the absence of medium, and is directly transmitted to a subject.
Implementation Method 2
Conduction heat is mainly conveyed by solids
