Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic wave heating apparatuses suffer from electromagnetic leakage due to gaps between the chamber body and door body, posing safety hazards and noise issues during operation, and lack reliable conductive connections for effective electromagnetic shielding.
Innovation Solution
The apparatus incorporates a slide rail assembly with conductive connectors that establish a stable and reliable conductive connection between the electromagnetic shielding features of the chamber body and door body, using fasteners and elastic parts to maintain electromagnetic sealing and reduce noise by ensuring smooth sliding and secure connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the door body is directly connected conductively to the chamber body when closed, then electromagnetic shielding is achieved, but gaps still exist between the chamber body and door body preventing effective electromagnetic sealing
Solution Approach 1:
The conductive connection is segmented into multiple components: the conductive connector with conductive elements, the slide rail assembly, and the electromagnetic shielding features on both door body and chamber body. This segmentation allows each component to perform its specific function while collectively achieving reliable electromagnetic shielding despite manufacturing gaps.
Solution Approach 2:
The conductive connector acts as an intermediary element between the door body and chamber body. It includes conductive elements that extend toward each other and make contact through the gap, serving as a mediator to establish conductive connection where direct contact is prevented by manufacturing tolerances.
2Ease of operation
If the door body is pushed and pulled during operation, then normal opening and closing is achieved, but noise is generated
Solution Approach 1:
The slide rail assembly provides a guided sliding mechanism that cushions and controls the movement of the door body during opening and closing. The rail structure预先 (in advance) prepares a smooth path that reduces impact and friction, thereby minimizing noise generation during door operation.
3Device complexity
If a simple direct connection is used between door body and chamber body, then device complexity is reduced, but the reliability of conductive connection is insufficient
Solution Approach 1:
The conductive connector incorporates movable conductive elements that can dynamically adjust their position within the gap between door body and chamber body. This dynamic capability ensures continuous conductive connection regardless of gap variations, significantly improving connection reliability without requiring an overly complex fixed structure.
