Solution Overview

Problem

Existing rail-guided amusement park devices, such as rollercoasters, face challenges in braking due to tight curves and unevenness in the rail course, making it difficult for conventional brake devices installed on the vehicle to effectively stop the vehicle at any desired point.

Innovation Solution

A brake device with a pivotally arranged brake pad carrier and brake pads that can pivot up to ±15° relative to the vehicle's direction of travel, allowing for flexible positioning and adjustment to compensate for rail irregularities, featuring a swivel pin, stop pins, and buffer elements to ensure secure braking at any point along the rail course.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If brake devices are fastened at the rail track at certain points, then braking power and effectiveness are improved, but the vehicle cannot be braked at any desired point along the route course

Engineering Contradiction:
Improvebraking powerVSAvoidbraking position flexibility
Core Design Contradiction:
PowerVSAdaptability or versatility

Solution Approach 1:

The brake pad carrier is made pivotable relative to the vehicle, allowing the brake pads to dynamically adjust their position and orientation. This enables the braking system to adapt to different locations along the rail track while maintaining effective braking power, resolving the contradiction between fixed braking points and flexible stopping positions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of brake pad position through pivoting motion. By allowing the brake pad carrier to pivot, the brake pads can reach different positions along the rail track, transforming a fixed-position system into one with variable positioning capability, thus enabling braking at any desired point.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If brake devices are located at the vehicle, then braking can occur at any position, but conventional brake devices cannot be used due to tight curves and unevenness in the rail course

Engineering Contradiction:
Improvebraking position flexibilityVSAvoidbraking effectiveness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The pivotable brake pad carrier allows the brake pads to dynamically compensate for rail irregularities and tight curves by adjusting their orientation. This maintains reliable braking effectiveness while preserving the ability to brake at any position along the route course.

Inventive Principle:
Principle #15Dynamics

3Speed

If brake pads are positioned close together, then braking response is faster, but unintended contact and friction loss occur in the idle state

Engineering Contradiction:
Improvebraking response speedVSAvoidfriction loss
Core Design Contradiction:
SpeedVSLoss of energy

Solution Approach 1:

The pivotable brake pad carrier enables the brake pads to be positioned close together for fast braking response while automatically pivoting to maintain a sufficient gap in the idle state. This dynamic adjustment prevents unintended contact and friction loss while preserving rapid braking capability.

Inventive Principle:
Principle #15Dynamics
