Solution Overview
Problem
There is a demand for efficiently irradiating objects with microwaves in a pull-out heating cooking apparatus while minimizing the size of the apparatus.
Innovation Solution
The apparatus includes a heating cooking chamber, a microwave supply unit, and a pull-out body with a waveguide positioned below the chamber to guide microwaves to a radiation port, allowing for efficient microwave irradiation while maintaining a compact design by positioning the support member and waveguide differently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the waveguide is positioned to efficiently guide microwaves to the radiation port, then microwave irradiation efficiency is improved, but the apparatus size increases
Solution Approach 1:
The waveguide is positioned in the vertical direction below the heating cooking chamber, utilizing the vertical dimension for microwave delivery. This allows efficient microwave guidance without increasing the horizontal footprint of the apparatus, thus improving irradiation efficiency while maintaining compact overall size.
Solution Approach 2:
The waveguide is nested within the vertical space below the heating cooking chamber, utilizing the available vertical volume. The support member for the pull-out body is positioned at a different location in the vertical direction, allowing both components to coexist in the limited space without interfering with each other.
2Stability of the object's composition
If the support member is positioned to support the pull-out body, then structural stability is improved, but the microwave guidance path is blocked
Solution Approach 1:
The support member and waveguide are positioned asymmetrically in the vertical direction, with the waveguide located below the heating cooking chamber and the support member positioned at a different vertical location. This asymmetric arrangement allows both components to perform their functions without mutual interference.
Solution Approach 2:
The spatial arrangement segments the vertical space into distinct zones: the waveguide occupies the lower zone for microwave guidance, while the support member is positioned in a different vertical zone to support the pull-out body. This segmentation eliminates functional conflicts between support and microwave delivery.
