Solution Overview
Problem
Existing substrate processing apparatuses face challenges in easily performing maintenance of their inner wall members, which are crucial for efficient operation and longevity.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inner wall member is fixed securely to ensure stable operation, then the reliability is improved, but the ease of maintenance deteriorates
Solution Approach 1:
The fixing mechanism is divided into multiple contact members distributed around the inner wall member. Each contact member can independently apply fixing force, allowing the system to maintain reliable fixation while enabling partial or complete disassembly for maintenance. The segmented structure permits controlled separation without compromising overall stability during operation.
Solution Approach 2:
The contact members are designed with movable components that can dynamically adjust between a fixed state (during operation) and a released state (during maintenance). The fixing mechanism transitions from a static permanent attachment to a dynamic reversible connection, allowing the system to adapt between reliability and maintainability requirements based on operational phase.
2Reliability
If a complex fixing mechanism is used to ensure secure attachment, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The contact members utilize elastic deformation of the support member itself to generate fixing force, eliminating the need for separate complex fastening components. The support member's own structural elasticity serves the dual purpose of providing mechanical support and generating retention force, simplifying the overall fixing mechanism while maintaining secure attachment.
Solution Approach 2:
The fixing mechanism relies on changing the elastic parameters (deformation amount, force magnitude) of the support member rather than introducing complex mechanical interlocks. By controlling the elastic deformation parameters, the system achieves secure attachment through simple geometric and material property adjustments rather than complex structural designs.
3Ease of repair
If the inner wall member is made detachable for easy maintenance, then the ease of maintenance is improved, but the reliability may deteriorate
Solution Approach 1:
The detachable design is implemented through segmented contact members rather than a single complex detachable connection. This segmentation allows the maintenance function to be achieved through simple separation of individual contact members while the overall multi-point attachment system maintains operational stability. The modular approach ensures that detachment for maintenance does not compromise the reliability of the remaining fixed connections.
