Self-Lifting Support Frame for Moving Integrated Vacuum Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Integrated vacuum systems are challenging to move due to their weight and bulk, requiring extensive assembly time and inhibiting operation of nearby systems, especially in confined spaces like subfabs, where conventional lifting equipment cannot be used effectively.
Innovation Solution
A conversion kit for support frames that includes a lifting mechanism with an extendible portion to lift the frame from within, allowing it to be moved without increasing the footprint, featuring hydraulic jacks or screw threads, and additional bracing for stability, enabling the frame to be assembled and transported in an assembled state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional lifting equipment is used to move the support frame, then the frame can be moved, but the equipment cannot be used in locations with limited space
Solution Approach 1:
The lifting mechanism is nested within the support frame structure itself. The extendible member is received within the movable element when retracted, and the entire lifting mechanism is mounted within the frame's outer envelope, allowing the frame to lift itself without requiring external lifting equipment that would occupy additional space
Solution Approach 2:
The support frame includes a self-contained lifting mechanism that enables it to lift itself. The extendible member extends to push the movable element downward, which in turn lifts the frame through the base, allowing the frame to be moved without requiring external lifting equipment
2Force
If the extendible member is extended to lift the frame, then lifting force is provided, but the height of the support frame increases
Solution Approach 1:
The lifting mechanism transitions from a static to a dynamic state during operation. The extendible member extends and contracts to provide lifting force, and the movable element moves between retracted and extended positions, allowing the frame to be lifted only when needed while maintaining a compact profile during normal operation
Solution Approach 2:
The lifting action occurs in the vertical dimension through the extendible member pushing downward on the movable element, which then lifts the frame. The horizontal footprint remains unchanged as the mechanism operates within the frame's existing envelope, separating the lifting function from lateral space requirements
3Area of stationary object
If the support frame is designed for compact footprint, then space efficiency is improved, but access for moving equipment is restricted
Solution Approach 1:
The lifting mechanism is segmented into distinct functional components: the extendible member, the movable element with support portions, and the base. This segmentation allows the mechanism to be integrated within the frame's footprint while providing the necessary lifting capability through coordinated movement of the segmented parts

Function Achieved in This Case
Enables the assembly and transport of integrated vacuum systems outside their operational environment, reducing installation time, minimizing personnel requirements, and allowing for easier maintenance by providing structural stability and self-lifting capabilities without expanding the equipment's footprint.
Implementation Method 1
the extendible member is extended and the movable element is pushed downwards by extension of the extendible member and the support portion(s) travel below the frame and contact the ground
Implementation Method 2
the support portion(s) travel below the frame and contact the ground, which impedes further movement downwards. At this point further extension of the extendible member causes the frame to lift

AI summary
A kit for converting a support frame for an integrated vacuum system from a static to a movable support frame along with the support frame and the integrated vacuum system is disclosed. The kit comprises: at least one frame lifting mechanism configured to be mounted within the support frame. The lifting mechanism comprises: a movable element configured to be movably mounted to the frame and an extendible member configured to extend between the movable element and a static member mounted on the frame. The movable element comprises at least one support portion extending from a lower surface of the movable element when the movable element is mounted to the frame. The extendible member is configured to be movable between a compressed state and an extended state. The movable element is configured to be mounted to the frame such that on extension of the extendible member the movable element is pushed downwards and the at least one support portion moves below a base of the frame and provides a lifting force to the frame.
