Solution Overview

Problem

Existing amusement devices, such as carousels and towers, provide repetitive experiences and require complex and energy-intensive mechanisms, which can be hazardous and costly to produce and operate, failing to offer a durable and safe thrill for users.

Innovation Solution

A gear system that allows for independent rotation of arms around a central shaft, with a distinct gear motor and safety gears to ensure synchronized movement and collision avoidance, reducing energy consumption and simplifying production, while allowing for a more dynamic user experience by simulating collisions between vehicles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a rotating gear at ground level is used to control arm rotation, then the arms can be rotated in opposite directions, but the structure becomes complex and energy-consuming due to the rotating gear and large structure inertia

Engineering Contradiction:
Improvearm rotation controlVSAvoidrotating gear structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the motor from the ground level and relocates it to the top of the central shaft. This removes the rotating gear structure from the ground level, simplifying the overall device complexity while maintaining the ability to rotate arms in opposite directions through the gear system at the top of the shaft.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent inverts the conventional arrangement by placing the motor at the top of the central shaft rather than at ground level. This inversion allows the gear system to operate differently, with the motor driving gears that control arm rotation without requiring a large rotating structure at ground level, thus reducing energy consumption and complexity.

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of operation

If a rotating gear at ground level is used to control arm rotation, then the arms can be rotated in opposite directions, but a great amount of energy is consumed due to the inertia of the large structure

Engineering Contradiction:
Improvearm rotation controlVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent extracts the motor from the ground level and relocates it to the top of the central shaft. This removes the rotating gear structure from the ground level, simplifying the overall device complexity while maintaining the ability to rotate arms in opposite directions through the gear system at the top of the shaft.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent inverts the conventional arrangement by placing the motor at the top of the central shaft rather than at ground level. This inversion allows the gear system to operate differently, with the motor driving gears that control arm rotation without requiring a large rotating structure at ground level, thus reducing energy consumption and complexity.

Inventive Principle:
Principle #13The other way round (Inversion)

3Adaptability or versatility

If visors are provided to create virtual reality experience, then user experience is improved, but the device becomes complex and expensive

Engineering Contradiction:
Improveuser experienceVSAvoidvisor system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical systems (such as visors for virtual reality) with a simpler mechanical solution. By using a gear system at the top of the central shaft to control arm rotation, the patent achieves enhanced user experience through mechanical means rather than through complex electronic or optical systems like visors.

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

4Adaptability or versatility

If the central shaft is rotated as a great structure, then the arms can be positioned dynamically, but a great amount of energy is consumed due to the inertia of the structure

Engineering Contradiction:
Improvearm positioningVSAvoidenergy consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent segments the rotation control into individual arm rotations controlled by the gear system at the top of the central shaft, rather than rotating the entire central shaft structure. This segmentation allows dynamic arm positioning while significantly reducing the mass and inertia that must be moved, thereby reducing energy consumption.

Inventive Principle:
Principle #1Segmentation
