Substrate Chamber Lifting Mechanism With Groove-Based Unit Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing substrate processing apparatuses face challenges in safe and simple maintenance due to complex screw operations and the risk of faulty insulation or electric shock during the attachment and removal of lifting mechanisms, which complicates the process of raising and lowering units for chamber maintenance.
Innovation Solution
A lifting mechanism with a power transmission switching mechanism that uses manually operated jacks and grooves to securely attach and detach units without compressed air or electricity, ensuring safe and simple maintenance by preventing rattling and ensuring proper alignment of grooves for secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw operations are used to attach and detach units, then secure connection is achieved, but operation complexity and time increase
Solution Approach 1:
The patent replaces the traditional screw-based mechanical fastening system with a groove-based mechanical engagement system. The lifting mechanism includes grooves that align with and engage corresponding protrusions on the units, allowing attachment and detachment through simple vertical movement rather than complex screw operations. This substitution maintains connection security while dramatically simplifying the operation process.
2Stability of the object's composition
If lifting mechanism is permanently connected, then structural stability is maintained, but maintenance accessibility decreases
Solution Approach 1:
The patent implements a dynamic connection system where the lifting mechanism can transition between attached and detached states through groove engagement. The grooves are designed to provide stable mechanical engagement when attached, ensuring structural stability during operation. Simultaneously, the engagement can be easily released by vertical movement, allowing quick access for maintenance. This dynamic design resolves the contradiction between stability and accessibility.
3Reliability
If complex fastening mechanisms are used, then secure attachment is ensured, but risk of electrical hazards increases
Solution Approach 1:
The patent extracts and eliminates electrical components from the attachment mechanism. Instead of using electrically complex fastening systems that could create insulation faults or electrical shocks, the invention uses a purely mechanical groove-based system with no electrical elements. This extraction of electrical hazards while maintaining mechanical security directly resolves the contradiction between attachment security and electrical safety.

AI summary
A substrate processing apparatus includes a chamber and units disposed above or on the chamber, at least one unit including a first groove. The substrate processing apparatus includes a lifting mechanism including at least one second groove, the lifting mechanism being configured to raise and lower each of the units. The units are configured to be raised and lowered in a state of being secured to the lifting mechanism, upon occurrence of a condition in which a fixing member is inserted into the first groove of the at least one unit and the second groove of the lifting mechanism.
