Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices face challenges in reliably shielding microwaves and suppressing water vapor in vacuum containers due to the thickness of vacuum hoses and water vapor generation exceeding the treatment capacity of vacuum pumps.
Innovation Solution
A microwave shielding container is integrated within the vacuum container, featuring microwave radiation parts and openings that allow gas flow while preventing microwave leakage, and includes a recovery unit to manage water vapor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vacuum hose is connected to pass through the container wall for vacuum pumping, then vacuum treatment can be performed, but microwave shielding becomes difficult due to the thick diameter of the vacuum hose
Solution Approach 1:
The container is divided into two separate functional components: a vacuum container for maintaining vacuum conditions and a microwave shielding container for blocking microwave radiation. This segmentation allows each component to optimize its specific function without compromise - the vacuum container can have simple vacuum hose connections while the microwave shielding container provides effective radiation blocking through its metallic structure
Solution Approach 2:
The microwave shielding container is placed inside the vacuum container, creating a nested structure. This allows the vacuum hose to connect only to the outer vacuum container wall, while the inner microwave shielding container remains sealed and provides complete microwave blocking. The nested arrangement solves both vacuum access and microwave shielding requirements simultaneously
2Reliability
If the vacuum pump capacity is increased to handle water vapor generation, then water vapor suppression improves, but device complexity and cost increase
Solution Approach 1:
A hydrophobic porous membrane is introduced as an intermediary component between the vacuum container interior and the vacuum pump. This membrane selectively allows water vapor molecules to pass through while blocking larger organic vapor molecules, enabling effective water vapor suppression with a standard-capacity vacuum pump rather than requiring an oversized pump system
