Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inclined elevators are limited by their constant gradient, restricting their ability to operate along a continuous variable trajectory, which is necessary for complex and variable slope applications.
Innovation Solution
A slope-adaptive inclined elevator system featuring a slope guide rail system, elevator car system, counterweight system, traction rope mechanisms, and governing rope systems that allow for automatic leveling and over-speed protection, enabling operation on variable slopes through a combination of guide rail supports, traction rope lifting and guiding devices, and governing rope systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If inclined elevators use a constant gradient design, then the structure is simple and stable, but the ability to operate along variable trajectory is limited
Solution Approach 1:
The guide rail system is designed with adjustable segments that can change the inclination angle dynamically. The guide rail support structure includes movable components that allow the rail to adapt to different slope angles, enabling the elevator to operate along variable trajectories while maintaining structural stability through controlled dynamic adjustment mechanisms.
Solution Approach 2:
The guide rail system is divided into multiple adjustable segments rather than a single fixed structure. Each segment can be independently positioned at different angles, allowing the elevator to navigate complex variable slopes by combining multiple linear segments, thus achieving trajectory adaptability through modular configuration.
2Adaptability or versatility
If the elevator car operates on variable slopes, then the application domain is expanded, but the stability of the car body is compromised
Solution Approach 1:
The car body incorporates an automatic leveling mechanism with movable support structures that dynamically adjust to maintain horizontal orientation. Sensors detect the slope angle and trigger hydraulic or mechanical leveling systems that reposition the car body to a horizontal position, ensuring passenger comfort and stability regardless of the underlying slope variation.
Solution Approach 2:
The counterweight system is designed to compensate for variations in load and slope angle. By adjusting the counterweight position and mass distribution, the system maintains balance and stability on variable slopes, preventing car body tilting and ensuring smooth operation across different terrain conditions.
3Adaptability or versatility
If traction rope mechanisms are added for slope adaptation, then the operational flexibility is improved, but the device complexity increases
Solution Approach 1:
The existing traction rope mechanism is enhanced with multi-functional components that serve both its original lifting function and the new slope adaptation function. The same traction system controls both vertical movement and horizontal positioning by varying the rope tension and pulley configuration, eliminating the need for separate dedicated slope adjustment mechanisms.
Solution Approach 2:
The slope adaptation features are integrated into the existing guide rail and traction systems rather than being added as separate independent mechanisms. The guide rail support structure combines slope adjustment functionality with the primary support function, and the traction system merges vertical lifting with horizontal positioning control, reducing overall system complexity through functional integration.
