Cable Transport System With Trolley Transfer Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable transport systems, such as zip-lines, require riders to disembark and re-embark at different cable segments for direction changes, due to interference from guide cable supports and terminations, limiting continuous operation and increasing the risk of operator error.
Innovation Solution
A powered carriage system with computerized control and a trolley transfer mechanism that allows seamless transition between cable segments, enabling continuous operation without the need for riders to leave the cable, using regenerative braking and alignment guides for smooth transitions and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional cable transport systems use discrete cable segments with guide cable supports, then the system can change direction between segments, but riders must disembark and re-embark at each segment transition, interrupting continuous operation
Solution Approach 1:
A transfer mechanism acts as an intermediary device at the cable segment transitions. This mechanism includes a transfer cable that runs parallel to the guide cable and a transfer trolley that moves along the transfer cable. The transfer trolley provides a continuous platform for riders as the guide cable transitions between segments, eliminating the need to disembark and re-embark while enabling direction changes between cable segments.
Solution Approach 2:
The cable transport system is divided into multiple cable segments that can be independently routed to achieve complex trajectories and direction changes. Each segment is supported by its own set of towers and can be configured to turn in different directions. The transfer mechanism bridges these segmented cables, allowing continuous operation across the segments without interrupting the ride.
2Adaptability or versatility
If guide cable supports and terminations are used to change cable direction, then the system can create multi-vectored courses, but these supports interfere with unobstructed trolley movement between segments
Solution Approach 1:
The transfer mechanism serves as an intermediary that bridges the gap between cable segments. The transfer cable runs parallel to the guide cable and the transfer trolley moves along this parallel cable, providing a smooth transition zone. This intermediary structure allows the guide cable to change direction at supports while maintaining unobstructed trolley movement through the transfer mechanism.
Solution Approach 2:
The transfer mechanism introduces a second cable dimension (the transfer cable running parallel to the guide cable) to resolve the interference problem. By moving the trolley onto this parallel cable for the transition portion, the system allows the guide cable to be routed through supports for direction changes without the trolley being blocked by these supports.
3Strength
If riders must leave the cable at cable segment endpoints, then guide cable supports can be positioned for optimal structural support, but this increases the risk of operator error and reduces safety
Solution Approach 1:
The transfer mechanism acts as a protective intermediary that keeps riders on the cable throughout the entire transition process. The transfer trolley provides a secure platform that spans the gap between cable segments, eliminating the moment when riders would be unattached during the transition. This continuous attachment reduces operator error risk and enhances safety while allowing optimally positioned support structures.
Solution Approach 2:
The transfer mechanism is designed to automatically guide the trolley from one cable segment to the next without requiring manual intervention or operator actions. The system self-regulates the transition process through mechanical guidance and alignment features, reducing the likelihood of operator error while maintaining safe and strong cable support structures.

AI summary
A system of devices facilitate the uninterrupted transport of a payload of persons (110) or cargo along a guide cable (180), or zip line, suspended from at least two support structures (120). Transfer mechanisms (800, 810) allow the cable to loop to a starting location or to transport between discrete endpoints. A trolley (200) carrying the payload may be powered by gravity alone, or a motorized assist may allow the cable course to be traversed without regard to relative elevations of cable supports. A motor may serve as a regenerative speed governor or braking device to charge a power supply for travel against gravity. The system enables one or more riders (110) to travel along the guide cable (180) at velocities desired for recreational purposes while assuming many body positions, such as prone, sitting or standing, to provide the sensation of flying like a bird.
