Vacuum Elevator Guide Pillar Sealing With Channel-Supported Cover Sheets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The sealing between covering sheets and columns in pneumatic vacuum elevators is prone to breakage due to relative movement, leading to air inflow and affecting the elevator's functionality.
Innovation Solution
A structure with angled sections and channel sections is used to support covering sheets, incorporating gasket linings and beading to provide vacuum-tight sealing, preventing relative movement and air inflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If covering sheets are tightened to columns using beadings and silicon, then the covering sheets can be secured to the columns, but the sealing may break due to relative movement between beadings and covering sheets
Solution Approach 1:
The patent introduces a channel section as an intermediary component between the beading and the covering sheet. This channel section provides a dedicated pathway that accommodates the beading while maintaining a stable sealing interface, preventing direct relative movement between the beading and the covering sheet that would otherwise compromise the silicon seal.
Solution Approach 2:
The patent utilizes the flexibility of the covering sheet in conjunction with the channel section design. The channel section allows the covering sheet to be secured firmly while accommodating minor movements or deformations without breaking the seal, effectively using the thin film's flexibility to maintain sealing reliability under stress.
2Reliability
If covering sheets are tightly secured to prevent movement, then sealing reliability improves, but the structure becomes more complex
Solution Approach 1:
The patent divides the column structure into distinct segments: the main column body, the channel section, and the beading component. This segmentation allows each part to perform its specific function independently - the channel section handles the sealing interface while the beading provides securing force - thereby achieving reliable sealing without requiring a monolithic complex structure.
Solution Approach 2:
The channel section serves multiple functions simultaneously: it provides a mounting interface for the covering sheet, accommodates the beading for securement, and maintains the sealing interface. This multi-functionality reduces the need for additional separate components, thereby achieving reliable sealing without proportionally increasing structural complexity.
