Cleaning Member Mounting Mechanism With Rotation Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cleaning member mounting mechanisms for substrate cleaning apparatuses are cumbersome and time-consuming due to the rotatable nature of the cleaning member holding parts, making it difficult to mount and replace cleaning member assemblies efficiently.
Innovation Solution
A cleaning member mounting mechanism that includes a cleaning member holding part, a member rotation part for rotating the cleaning member assembly, and a moving part that restricts the rotation of the holding part by moving it into a fixed position along the axial direction, allowing for easy mounting and replacement of cleaning member assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning member holding part is made rotatable to enable cleaning member assembly replacement, then the cleaning member can be replaced, but the mounting process becomes time-consuming and cumbersome
Solution Approach 1:
The moving part performs a preliminary action by automatically moving the cleaning member holding part to the rotation fixed position when the cleaning member assembly is removed. This preliminary positioning action restricts rotation before mounting begins, eliminating the need for manual rotation adjustment during mounting and significantly reducing mounting time.
2Ease of operation
If the cleaning member holding part remains rotatable during mounting, then the cleaning member can be installed, but the holding part may rotate during the process making mounting difficult
Solution Approach 1:
The system dynamically changes the rotational state of the cleaning member holding part based on operational needs. When the cleaning member assembly is present, the holding part remains rotatable for cleaning operations. When the assembly is removed, the moving part automatically transitions the holding part to a rotation fixed position, providing stability during mounting and replacement operations.
3Stability of the object's composition
If a complex locking mechanism is added to restrict rotation during mounting, then rotation can be fixed, but the device complexity increases
Solution Approach 1:
The moving part serves itself by automatically moving the cleaning member holding part to the rotation fixed position when the cleaning member assembly is removed. This self-service mechanism eliminates the need for external locking devices or complex fixation mechanisms, achieving rotation restriction through the inherent movement capability of the moving part itself.

AI summary
A cleaning member mounting mechanism has: a cleaning member holding part, to which a cleaning member assembly having a cleaning member for cleaning a substrate W can be mounted; a member rotation part for rotating the cleaning member assembly held by the cleaning member holding part; and a moving part which moves the cleaning member holding part along an axial direction when the cleaning member assembly is removed, thereby to bring the cleaning member holding part into a rotation fixed position to restrict a rotation of the cleaning member holding part.
