Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooking apparatuses using electromagnetic waves face issues with electromagnetic wave leakage through photographing openings, which can damage components and pose health risks, and conventional designs limit the aperture ratio of optical signal passage, affecting image quality.
Innovation Solution
Incorporation of a resonance avoiding chamber between the cooking chamber and the photographing device, along with a cooling fan system to minimize electromagnetic wave leakage and maximize the aperture ratio for optical signal passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a photographing opening is provided in the cabinet to allow optical signal passage, then image quality is improved, but electromagnetic waves leak through the opening causing safety issues and component damage
Solution Approach 1:
A resonance avoiding chamber is introduced as an intermediary structure between the cooking chamber and the photographing device. This chamber acts as a buffer zone that prevents direct electromagnetic wave transmission through the opening while still allowing optical signals to pass through, thus resolving the contradiction between image quality and electromagnetic wave leakage prevention
Solution Approach 2:
The cabinet structure is segmented by dividing the space into distinct functional zones: the cooking chamber, the resonance avoiding chamber, and the photographing device chamber. This segmentation allows the opening to be positioned in a controlled manner within the resonance avoiding chamber, enabling optical passage while containing electromagnetic waves through the chamber's resonant frequency design
2Measurement precision
If the aperture ratio of the opening is increased to improve optical signal passage, then image quality is improved, but electromagnetic wave leakage is intensified
Solution Approach 1:
The resonance avoiding chamber serves as a mediator that decouples the relationship between aperture size and electromagnetic wave leakage. By positioning the opening within this chamber, the design allows for a larger aperture ratio to improve image quality while the chamber's resonant properties contain and suppress electromagnetic wave transmission, preventing leakage intensity from increasing proportionally with aperture size
