Solution Overview
Problem
Existing processing rooms fail to maintain an effective inert atmosphere for easily oxidized workpieces, leading to oxidation during processing.
Innovation Solution
A processing room design incorporating a processing chamber, gas storage chamber, discharge chamber, sealing member, blocking member, and reclaiming member, which creates a hermetical environment using inert gas and vacuumization to prevent oxidation, allowing for the processing and removal of workpieces while maintaining an inert atmosphere.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a processing chamber with vacuum pump is used, then oxidation is prevented, but device complexity increases
Solution Approach 1:
The system is divided into three independent chambers: processing chamber, gas storage chamber, and discharge chamber. Each chamber performs a specific function and can be independently sealed and controlled, allowing the complex vacuum/inert atmosphere function to be distributed across multiple simpler modules rather than one complex integrated system.
Solution Approach 2:
The gas storage chamber acts as an intermediary between the external environment and the processing chamber. It stores inert gas and provides it to the processing chamber when needed, mediating the atmosphere control function and simplifying the direct connection between vacuum pump and processing chamber.
2Reliability
If hermetical sealing is implemented, then inert atmosphere is maintained, but ease of operation decreases
Solution Approach 1:
The discharge chamber is separated from both the processing chamber and the external environment, creating an intermediate buffer zone. This segmentation allows workpieces to be transferred through the sealed system without breaking the inert atmosphere in the processing chamber, maintaining atmosphere control while enabling easy workpiece removal through the discharge chamber interface.
Solution Approach 2:
The discharge chamber serves as an intermediary space that facilitates workpiece removal. It provides a sealed transition zone where workpieces can be moved from the processing chamber to external handling without exposing them to air, thus maintaining atmosphere control while simplifying the removal operation.
3Reliability
If multiple chambers are added, then processing reliability is improved, but device complexity increases
Solution Approach 1:
The gas storage chamber serves multiple functions: it stores inert gas for atmosphere control, acts as a seal between the processing chamber and external environment, and provides pressure equalization. This multi-functionality reduces the need for additional dedicated components, offsetting the complexity increase from adding chambers.
Solution Approach 2:
The discharge chamber is positioned within or adjacent to the processing chamber structure, with the sealing member integrated into the chamber assembly. This nested arrangement minimizes the overall structural complexity by having chambers share common walls and mounting structures rather than being completely separate units.

AI summary
A processing room includes a processing chamber, a discharge chamber, a sealing member, a blocking member, and a reclaiming member. The discharge chamber includes a main body communicating with the processing chamber, and a receiving portion and a discharge portion communicating with the main body. The receiving portion is aligned to the discharge portion. The sealing member includes a sealing portion and a sealing valve mounted on the sealing portion. The sealing portion is partially and moveably received in the receiving portion and resists against a sidewall of the receiving portion. The blocking member is detachably mounted on an end of the discharge portion and seals the discharge portion. The reclaiming member is partially received in the main body.
