Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking appliances with multiple heat sources face challenges in accommodating camera modules due to space constraints and heat interference, leading to reduced view angles and potential damage from high temperatures.
Innovation Solution
A cooking appliance design with a camera module positioned at the rear surface, utilizing an inclined mounting surface and a regular circular filming hole to minimize space requirements and protect the camera from heat, while separate cooling and insulation systems ensure effective temperature management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera is installed horizontally inside the cooking room, then the camera can capture images of the cooking space, but it is difficult for the camera to capture images of the bottom of the cooking room on which food is placed
Solution Approach 1:
The camera module is inverted and installed on the rear surface of the casing instead of being mounted horizontally inside the cooking room. This inversion allows the camera to capture images of the bottom of the cooking room where food is placed, solving the problem of limited viewing angle while keeping the camera protected outside the high-temperature cooking environment.
2Measurement precision
If the camera is installed in an inclined direction to secure a view angle, then the camera can capture images of the bottom of the cooking room, but a filming hole that has a long-hole shape or a large diameter must be formed on a side wall of the cooking room which generates noise in the camera due to influence of microwaves and deteriorates quality of capturing
Solution Approach 1:
The camera module is extracted from the cooking room interior and installed on the rear surface of the casing. This separation eliminates the need for a large or long-hole filming hole in the cooking room walls, thereby preventing microwave noise from interfering with the camera while still allowing the camera to capture images of the cooking space including the bottom area.
Solution Approach 2:
The rear surface of the casing serves as an intermediary location for mounting the camera module. This intermediate position allows the camera to observe the cooking room through a small filming hole without being exposed to microwave noise inside the cooking chamber, thus maintaining both viewing capability and signal quality.
3Productivity
If multiple heat sources are used to heat food, then food can be cooked more uniformly and quickly, but the temperature inside the cooking room increases and there is a risk that a camera sensor is damaged due to high temperature heat
Solution Approach 1:
The camera module is extracted from the high-temperature cooking environment and installed on the rear surface of the casing. This separation protects the camera sensor from damage due to high temperature heat generated by multiple heat sources, while the camera can still capture images of the cooking process through a small filming hole.
4Adaptability or versatility
If space is allocated for mounting camera modules and various heat sources, then the camera module can be installed, but the cooking appliances occupy a large volume in the living space
Solution Approach 1:
The rear surface of the casing serves multiple functions: it acts as the external housing surface and simultaneously provides a mounting location for the camera module. This multi-functional use of space allows the camera to be installed without increasing the overall appliance volume, as the camera utilizes the existing rear surface structure rather than requiring additional internal space.
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 allows for a wide view angle, improved capturing quality, and enhanced durability of the camera module by preventing heat damage and noise interference, while maintaining efficient cooling and reduced risk of contamination.
Implementation Method 1
a microwave oven is a high-frequency heating type of cooking appliance. The microwave oven heats food by using molecules in a high-frequency electric field vibrating strongly to generate heat.
Implementation Method 2
An induction heating electric range is a cooking appliance that uses electromagnetic induction to heat an object to be heated. Specifically, when high-frequency power of a predetermined size is applied to a coil, the induction heating electric range generates eddy currents in the object to be heated, which is made of a metal substance, using a magnetic field generated around the coil, and thus heating the object to be heated.
Implementation Method 3
a first cooling fan module arranged in the first electric chamber and configured to cool the camera module and a second cooling fan module arranged in the second electric chamber and configured to cool the heat source module and other parts

AI summary
A cooling appliance is proposed. A casing (100, 200) includes a cavity (S) therein, and a heat source module may be arranged inside the casing (100, 200). Furthermore, a camera module (730) is arranged at a rear surface of the casing (100, 200) and capture the inside space of the cavity (S). Accordingly, in the casing (100, 200), heat sources and the camera module (730) are arranged without interference therebetween, and the camera module (730) can secure a wide view angle at a rear portion of the casing (100, 200).
