Solution Overview

Problem

Current cable transport systems, particularly those with fixed grippers, face challenges in improving passenger transport speed and throughput, as stationary cabins can block the path of other vehicles, requiring multiple landing/boarding stations and not efficiently managing cabin order along the traction cable.

Innovation Solution

A device with movable arms that can unhook a cabin from the cable and rehook it at a different station, allowing for flexible cabin positioning and movement, enabling continuous traction cable operation while avoiding collisions and optimizing embarkation/disembarkation without disrupting other vehicles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cabins are stopped in the normal path of vehicles at a station for boarding/disembarking, then passenger boarding and disembarking can be completed, but the stationary cabin blocks the path of other cabins in the station

Engineering Contradiction:
Improveboarding and disembarking capabilityVSAvoidpassenger throughput
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent applies the dynamics principle by making the arm movable relative to the coupling means, allowing it to shift cabins laterally within the station. This dynamic positioning enables a stationary cabin to be moved out of the normal path to allow other cabins to pass, while still permitting boarding and disembarking operations to occur at the station without blocking traffic flow

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces a lateral dimension of movement through the arm's ability to shift cabins perpendicular to the cable's direction of travel. This additional degree of freedom allows cabins to be repositioned within the station area, enabling the system to resolve the conflict between stopping for passenger operations and maintaining continuous traffic flow by moving cabins out of the way when necessary

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If the order of cabins along the haul rope is fixed throughout the entire route, then cable transport operation is simple, but passenger throughput cannot be improved and collision risk increases when a cabin is stopped at a station

Engineering Contradiction:
Improvecable transport operation simplicityVSAvoidpassenger throughput
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent makes the cabin order dynamic by enabling the arm to laterally shift cabins along the haul rope at stations. This allows the system to change the sequence of cabins during operation - for example, moving a cabin that has completed its route out of the way and allowing newer cabins to take its position, thereby improving throughput without requiring complete system redesign

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the cable transport system into distinct operational zones: the normal travel path where fixed order is maintained for simplicity, and the station area where the movable arm enables local reordering of cabins. This segmentation allows the system to maintain operational simplicity in the majority of the route while enabling throughput improvements at specific locations

Inventive Principle:
Principle #1Segmentation

3Productivity

If multiple disembarkation/boarding stations are installed to prevent blocking, then passenger throughput is improved, but the installation becomes complex

Engineering Contradiction:
Improvepassenger throughputVSAvoidinstallation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent makes the single station multi-functional by equipping it with a movable arm that can perform multiple operations: boarding, disembarking, lateral shifting of cabins to clear the path, and reordering of cabins along the haul rope. This universal capability allows the station to handle all passenger operations and traffic management functions in one location, eliminating the need for multiple specialized stations

Inventive Principle:
Principle #6Universality (Multi-functionality)
