Solution Overview

Problem

Existing wireless communication systems in amusement park attractions experience interference due to the use of consumer frequency bands, leading to signal bleed between scenes and limited connectivity, which can affect the synchronization and safety of complex ride experiences.

Innovation Solution

Utilizing high-frequency bands (60-80 GHz) for wireless communication that require line-of-sight transmission and are less susceptible to interference, combined with localized sensor networks and controllers to manage and synchronize attraction vehicles and scenes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional wireless communication techniques using consumer frequency bands are used, then wireless communication is available and easy to implement, but signal interference and bleed between attractions occur

Engineering Contradiction:

Improvewireless communication reliabilityVSAvoidsignal interference

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the frequency parameter of wireless communication from traditional consumer bands (2.4 GHz, 5 GHz) to high-frequency bands (60-80 GHz). This parameter change reduces signal propagation distance and eliminates interference between attractions while maintaining wireless communication capability. The high-frequency signals are confined to shorter ranges, preventing bleed between different ride attractions.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent implements location-specific frequency assignment where different attraction locations use different high-frequency bands. Each attraction or scene is assigned a specific frequency within the 60-80 GHz range, creating localized wireless communication zones that do not interfere with each other. This local quality approach ensures that wireless communication is optimized for each specific location without affecting neighboring attractions.

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If high-frequency bands (60-80 GHz) are used for wireless communication, then interference is reduced and transmission is isolated, but transmission distance is limited and requires line-of-sight

Engineering Contradiction:

Improvesignal interferenceVSAvoidtransmission distance

Core Design Contradiction:

Object-affected harmful factorsVSLength of stationary object

Solution Approach 1:

The patent divides the attraction into multiple zones with dedicated access points, each handling local wireless communication. By segmenting the communication infrastructure into distributed access points throughout the attraction, the system compensates for the limited transmission distance of high-frequency signals. Each access point serves a localized area, ensuring complete coverage through strategic placement rather than relying on long-range transmission.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces wireless access points as intermediary devices between attraction vehicles and the central control system. These access points receive and transmit high-frequency signals over short distances, acting as mediators that bridge the gap created by limited transmission range. The access points are strategically positioned to ensure line-of-sight connectivity with vehicles in their respective zones.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple locations transmit information simultaneously, then each location can operate independently, but signal bleed causes unintended actions in other locations

Engineering Contradiction:

Improvelocation independenceVSAvoidsignal isolation

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent assigns different frequency parameters to different locations within the attraction. Each scene or attraction zone operates on a unique high-frequency band within the 60-80 GHz range, enabling simultaneous independent operation without signal bleed. This frequency division multiplexing allows multiple locations to transmit information simultaneously while maintaining complete isolation between them.

Inventive Principle:

Principle #35Parameter changes
