Solution Overview

Problem

Existing amusement park ride control systems are inefficient, costly to maintain, and limit the freedom of movement of ride vehicles, making it difficult to synchronize their movements and maintain desired distances between them.

Innovation Solution

A ride control system that uses a central controller to synchronize the movements of separate groups of ride vehicles, or 'virtual trains,' by assigning schedules with expected positions and timestamps, allowing individual vehicles to adjust their speed and position to maintain predetermined distance ranges, enabling efficient and coordinated control of physically separate ride vehicles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional ride control systems are used to measure and calculate location and speed of each ride vehicle, then spacing between ride vehicles can be maintained, but the system becomes difficult to implement, inefficient to operate, and costly to maintain

Engineering Contradiction:
Improvespacing maintenanceVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system divides the train into multiple independent ride vehicle groups (first group and second group) that can be controlled separately. Each group has its own controller that manages speed and position independently, reducing the complexity of centralized control while maintaining proper spacing between all vehicles through coordinated group management.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control system dynamically adjusts the speed of each ride vehicle group based on real-time position feedback and predetermined spacing requirements. The system transitions from static fixed-speed operation to dynamic speed modulation, allowing vehicles to accelerate and decelerate smoothly while maintaining safe distances, thereby reducing control complexity.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If ride vehicles are mechanically connected to maintain spacing, then desired distances are maintained, but the freedom of movement of individual vehicles is limited

Engineering Contradiction:
Improvedistance maintenanceVSAvoidvehicle movement freedom
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The system replaces mechanical couplings or physical connections between ride vehicles with an electronic control system. Each vehicle group is equipped with sensors and controllers that communicate wirelessly or through the control network, enabling spacing maintenance through electronic coordination rather than mechanical constraint, thus preserving vehicle movement freedom.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

Each ride vehicle group operates autonomously with its own controller that independently manages its speed and position based on feedback from position sensors and commands from the central control system. This self-regulating capability allows vehicles to maintain proper spacing without external mechanical constraints, enhancing movement flexibility.

Inventive Principle:
Principle #25Self-service

3Productivity

If separate groups of ride vehicles are controlled independently, then operational efficiency is improved, but synchronization of movements between groups becomes difficult

Engineering Contradiction:
Improveoperational efficiencyVSAvoidmovement synchronization
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The control system continuously monitors the position and speed of each ride vehicle group using sensors and feedback devices. This real-time feedback information is transmitted to the central controller, which compares actual positions against predetermined spacing requirements and dynamically adjusts control commands to maintain synchronization between groups, ensuring reliable coordinated movement.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

While each ride vehicle group is controlled independently for operational efficiency, the control systems are merged through a centralized control architecture that coordinates all groups. The central controller integrates information from all groups and issues synchronized control commands, combining the benefits of independent operation with reliable movement synchronization.

Inventive Principle:
Principle #5Merging (Combining)
