Vertical Loop Gondola System for Urban Transit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gondola systems struggle to provide high-capacity passenger transportation in urban environments due to their large footprint and inability to operate effectively in constrained spaces, as they require significant horizontal space for horizontal loop configurations and do not meet the throughput needs of densely populated areas.
Innovation Solution
A vertical loop gondola transportation system where cabins circulate in a single or double vertical loop configuration, allowing for passenger loading and unloading at different levels, with independent track ropes and support structures that minimize horizontal space usage, enabling operation in narrow corridors and increasing capacity to up to 12,000 passengers per hour per direction.

Engineering Contradiction Analysis
1Productivity
If conventional horizontal gondola systems are used, then passenger transportation is provided, but significant horizontal space is required for loop configuration and supporting structures
Solution Approach 1:
The patent transitions from a horizontal loop configuration to a vertical loop configuration for the gondola system. This dimensional change allows the system to achieve high passenger capacity while minimizing horizontal footprint, as the loop now extends vertically rather than horizontally, enabling installation in constrained urban environments with limited ground space.
Solution Approach 2:
The patent implements a nested structure where the outbound and return cables are positioned one above the other vertically, with the return cable nested within the spatial envelope of the outbound cable's vertical path. This nesting approach eliminates the need for side-by-side horizontal cable routing, significantly reducing the horizontal space required for supporting structures.
2Ease of operation
If conventional horizontal loop configuration is used, then gondola operation is enabled, but significant horizontal spacing is required for adjacent cables and supporting structures
Solution Approach 1:
The system maintains full gondola operational capability by reconfiguring the loop from horizontal to vertical orientation. The vertical arrangement of cables and supporting structures preserves the essential bidirectional gondola operation while eliminating the need for large horizontal spacing between adjacent cables and support elements.
Solution Approach 2:
The patent employs asymmetric vertical positioning of the outbound and return cables at different elevations, with the return cable positioned below the outbound cable. This asymmetric arrangement allows both cables to operate independently without requiring symmetric horizontal spacing, optimizing the use of vertical space and minimizing horizontal footprint.
3Productivity
If horizontal gondola systems are installed in existing urban areas, then passenger transport is provided, but installation is difficult due to limited space from existing infrastructure
Solution Approach 1:
The vertical loop configuration enables the gondola system to adapt to constrained urban environments by utilizing vertical space rather than horizontal space. This dimensional transition allows installation in areas with limited ground availability, such as between existing buildings or over constrained rights-of-way, significantly improving adaptability to existing urban infrastructure.
Solution Approach 2:
The patent employs a dynamic cable routing system where the cables follow a vertical loop path that can be adjusted and configured to fit specific urban constraints. The supporting structures are positioned to accommodate the vertical loop geometry, allowing the system to adapt dynamically to varying site conditions and existing infrastructure limitations.

AI summary
A system, method and device for moving gondola cabins in a single vertical loop so as to pass above and below with end stations turning wheels placed vertically. The hauling ropes operate in a vertical loop and permit the vertical circulation of the cabins between stations with passenger boarding and deboarding of the cabins in the stations at two different levels. The system may be twinned to provide two parallel, horizontally adjacent systems operating on common towers to double the capacity of a single system. Both the single and twinned systems possess a smaller footprint than conventional horizontal transport systems.
