Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication in amusement park attractions experiences interference due to traditional consumer frequency bands, leading to signal bleed between scenes and limited connectivity, which can disrupt synchronization and safety mechanisms.
Innovation Solution
Utilizing high-frequency bands (60-80 GHz) for wireless communication that require line-of-sight and are less prone to penetration, isolating attractions from external noise and minimizing interference by structuring walls to block signals, and employing localized sensor networks with high-speed data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional consumer frequency bands are used for wireless communication in attractions, then ease of operation and compatibility are improved, but signal interference and bleed between scenes increase
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 GHz, 80 GHz). This parameter change reduces signal penetration and interference between scenes while maintaining communication capability, directly resolving the contradiction between ease of operation and signal interference.
Solution Approach 2:
The patent segments the wireless communication spectrum by assigning different high-frequency bands to different scenes or attraction areas. This segmentation prevents signal bleed between adjacent scenes while maintaining ease of operation within each scene, addressing both the compatibility and interference issues.
2Object-affected harmful factors
If high-frequency bands (60-80 GHz) are used for wireless communication, then signal interference and bleed between scenes are reduced, but connectivity and signal penetration capability deteriorate
Solution Approach 1:
The patent transitions from two-dimensional wireless signal propagation (traditional bands that penetrate walls) to line-of-sight three-dimensional communication (high-frequency bands). This dimensional change requires direct visual contact between transmitter and receiver, ensuring reliable connectivity within scenes while preventing interference between scenes through structural walls.
Solution Approach 2:
The patent uses structural walls as intermediaries to block high-frequency signals between scenes. These walls act as natural barriers that prevent signal penetration, maintaining reliable connectivity within each scene while eliminating interference with adjacent scenes.
3Productivity
If multiple locations transmit information wirelessly, then information availability and responsiveness are improved, but interference and inadvertent actions in other locations increase
Solution Approach 1:
The patent assigns different high-frequency bands to different transmission locations within the attraction. This parameter differentiation allows multiple locations to transmit information simultaneously at high speeds without causing interference, as each location operates on a dedicated frequency channel.
