Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a scatter preventing cup is used to vent gas, then gas venting is improved, but processing liquid atmosphere discharge is insufficient
Solution Approach 1:
The exhaust system is divided into two separate paths: one for gas venting through the scatter preventing cup, and another for processing liquid atmosphere discharge through the rotation exhaust cup. This segmentation allows each component to specialize in its function, with the rotation exhaust cup specifically designed to capture and discharge liquid droplets and gasified processing liquid that the scatter preventing cup cannot effectively handle.
Solution Approach 2:
The rotation exhaust cup is designed to rotate together with the support part, creating a dynamic exhaust system that can effectively track and capture the processing liquid atmosphere as the target object rotates. This rotational movement ensures continuous contact with the liquid atmosphere regardless of the target object's position, significantly improving discharge effectiveness compared to static exhaust structures.
2Device complexity
If processing liquid atmosphere is not effectively discharged, then device complexity is reduced, but particle formation on target object increases
Solution Approach 1:
The rotation exhaust cup acts as an intermediary component between the processing liquid atmosphere and the discharge mechanism. It specifically captures liquid droplets and gasified processing liquid that escape the main exhaust path, directing them to the discharge mechanism. This intermediary function prevents particles from forming on the target object without requiring complete redesign of the entire exhaust system.
3Object-generated harmful factors
If rotation cup and rotation exhaust cup are added, then processing liquid atmosphere discharge is improved, but device complexity increases
Solution Approach 1:
The rotation exhaust cup is merged with the existing rotational support structure, causing it to rotate together with the support part and target object. This integration allows the exhaust mechanism to leverage the existing rotational motion without requiring separate drive systems, reducing the overall complexity increase despite adding functional components.
Solution Approach 2:
The rotation exhaust cup serves multiple functions: it acts as both a capture structure for processing liquid atmosphere and as a rotational component that moves with the target object. This multi-functionality reduces the need for additional dedicated components, thereby limiting the increase in device complexity while maintaining effective liquid atmosphere discharge.

Function Achieved in This Case
The apparatus ensures effective discharge of the processing liquid atmosphere, preventing residual chemical solutions from causing particles on the target object and maintaining a balanced flow of processing liquid, thereby enhancing processing efficiency and preventing vortex flows.
