Variable Speed Belt Deceleration System for Aerial Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing movement systems in aerial transport installations that use hauling cables face high maintenance costs and rapid wear due to the need for regular tire pressure checks and frequent replacement of tires used in slowing and accelerating devices.
Innovation Solution
A movement system that employs a slowing device with at least a first and a second slowing belt, each driven by a variable speed motor, allowing simultaneous deceleration of multiple vehicles and reducing wear, and an acceleration device with similar belt configurations to enhance capacity and reduce maintenance needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tires are used in braking and acceleration devices, then vehicles can be slowed down and accelerated, but tire pressure must be checked regularly and tires wear out quickly, resulting in high maintenance costs
Solution Approach 1:
The patent replaces the mechanical tire-based braking and acceleration system with a frictionless magnetic field-based system. Electromagnets mounted on the vehicle interact with conductive rails in the station to produce braking and acceleration forces, eliminating the need for physical contact and wear-prone components like tires.
Solution Approach 2:
The patent uses electromagnetic fields (an extension of fluid/particle field principles) to transmit force without physical contact. The electromagnetic interaction between the vehicle's magnets and the station's rails creates the necessary forces, analogous to how pneumatic or hydraulic systems use fluid pressure to transmit force without direct mechanical contact.
2Productivity
If a single deceleration belt is used, then one vehicle can be decelerated at a time, but the capacity of the aerial transport installation is limited
Solution Approach 1:
The deceleration device is segmented into multiple independent deceleration belts (at least two), each capable of decelerating a vehicle simultaneously. This segmentation allows parallel processing of multiple vehicles, increasing the overall capacity of the installation without requiring a single complex sequential system.
3Productivity
If multiple tires are used for braking and acceleration, then more vehicles can be processed, but the wear on tires increases and maintenance requirements increase
Solution Approach 1:
The patent replaces mechanical tire-based systems with electromagnetic field-based systems, eliminating physical wear entirely. The electromagnetic interaction between vehicle magnets and station rails provides the necessary forces without any consumable components, thus eliminating tire wear and associated maintenance.
