Suspended Monorail Transit System with Two-Position Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current public transit systems are inefficient due to traffic congestion, inconsistent schedules, and high maintenance costs, and contribute to pollution and noise pollution, with delays caused by loading and unloading passengers and cargo.
Innovation Solution
A suspended overhead monorail public transit system with electrically driven vehicles, featuring a two-position switch for lateral movement, an elevator-type mechanism for street-level access, and pivotal mechanisms for tight turns, allowing for efficient passenger and cargo transport with reduced infrastructure interference and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If public transit vehicles operate on surface streets, then they can provide accessible service, but they experience traffic congestion and delays
Solution Approach 1:
The patent transitions the transit system from two-dimensional surface street operation to three-dimensional elevated monorail operation. The monorail tracks are suspended above street level, allowing vehicles to travel in an elevated dimension that bypasses surface traffic congestion while maintaining route coverage. This dimensional shift resolves the contradiction by eliminating traffic delays without sacrificing accessibility, as passengers can still board and alight at ground-level stations.
2Productivity
If more public transit vehicles are added to increase capacity, then more passengers can be transported, but traffic congestion and infrastructure strain increase
Solution Approach 1:
By moving the transit system to an elevated dimension, the patent enables increased vehicle capacity and frequency without adding to surface street congestion. Multiple monorail vehicles can operate simultaneously on elevated tracks, increasing productivity while avoiding the traffic delays that would result from adding more ground-level vehicles.
3Adaptability or versatility
If traditional internal combustion engine vehicles are used, then infrastructure compatibility is maintained, but carbon emissions and noise pollution increase
Solution Approach 1:
The patent replaces internal combustion engine propulsion with electric motor propulsion. The monorail vehicles are powered by electric motors that draw energy from overhead wires or onboard batteries, substituting the mechanical combustion system with an electrical system. This eliminates carbon emissions and significantly reduces noise pollution while maintaining adaptability to urban infrastructure through the use of standard electric power delivery systems.
4Ease of operation
If passenger loading and unloading stops are extended to accommodate passengers, then passenger service is improved, but travel time between destinations increases
Solution Approach 1:
The patent implements preliminary action by having passengers board and alight at elevated platforms that are pre-positioned at each stop. The monorail vehicles pull into these pre-prepared platforms, allowing for efficient passenger transfer without requiring extended stopping times. This preliminary arrangement of boarding facilities enables quick passenger service while minimizing the time vehicles are stopped, thereby reducing total travel time.

AI summary
Transit systems for travel overhead of streets, having: at least a first vehicle and a second vehicle; a main track on which the vehicles travel, the main track having a suspended overhead rail over the streets by a support structure, such that the vehicles travel at an elevated level overhead of street level; docking stations for the vehicles to lower to the street level for loading and/or unloading passengers and/or cargo; a two-position switch at each docking station, having cables enabling vertical movement of the vehicle, and a replacement track; wherein the two-position switch allows for docking of the first vehicle while the second vehicle passes the docked first vehicle, by enabling lowering of the first vehicle from the elevated level to the street level, and the replacement track providing a track portion for the second vehicle on which to pass the first vehicle.
