Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional traction elevators are used, then the elevator can transport people efficiently, but the footprint and installation cost increase significantly
Solution Approach 1:
The patent replaces the traditional mechanical traction system (ropes, pulleys, counterweights) with a pneumatic system using air pressure differential to move the cabin, eliminating the need for heavy mechanical components and reducing the overall footprint
Solution Approach 2:
The invention uses pneumatic pressure differential created by a vacuum pump to lift and lower the cabin, substituting mechanical force with pneumatic force, which allows for a more compact design without sacrificing transport efficiency
2Device complexity
If hydraulic elevators are used, then the elevator can operate without overhead machinery, but the installation cost and environmental impact increase
Solution Approach 1:
The patent replaces the hydraulic fluid-driven piston system with a pneumatic vacuum system, eliminating the need for hydraulic fluid, large-diameter cylinders, and complex sealing mechanisms, thereby reducing installation complexity and cost
Solution Approach 2:
The invention changes the working medium from hydraulic fluid to air (pneumatic), and uses vacuum pressure differential instead of positive pressure, which allows for smaller component sizes and simpler construction while maintaining operational capability
3Shape
If glass panels are used as construction elements, then the aesthetic appearance improves, but the structural strength and safety may be compromised
Solution Approach 1:
The patent uses tempered glass panels as the primary structural material, combining the aesthetic qualities of glass with the enhanced strength provided by tempering treatment, creating a composite material solution that satisfies both appearance and strength requirements
Solution Approach 2:
The invention changes the material properties of glass through tempering treatment, which increases the strength and durability of the glass panels, allowing them to serve as both structural and aesthetic elements without compromise
4Area of stationary object
If vacuum elevators are used, then the elevator becomes compact and aesthetically pleasing, but the speed and load capacity are limited
Solution Approach 1:
The patent optimizes the vacuum pressure differential parameters and cabin design to maximize the speed and load capacity within the constraints of the compact vacuum elevator system, achieving efficient operation despite the limited footprint

AI summary
Techniques are described for an elevator apparatus that includes a cabin apparatus and a hoistway apparatus. In an embodiment, the cabin head apparatus of the cabin apparatus extends parallel to a cross-section of the hoistway apparatus. The air pressure in the part of the hoistway is maintained to be different from the air pressure inside the cabin apparatus and may cause the cabin apparatus to ascend or to stay steady within the hoistway apparatus. The cabin head apparatus is partially load-bearing for the cabin apparatus and any load. In an embodiment, the air pressure difference is maintained by seal(s) that are peripherally coupled to the cabin apparatus, generating an airtight connection of the cabin apparatus with an inner periphery of a cross section of the hoistway apparatus. The seals substantially prevent the air in the top portion of the hoistway apparatus from entering the bottom portion and vice versa.
