Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location systems fail to effectively monitor and guide individuals in crowded venues such as concerts, sporting events, and conventions, leading to long waits and difficulties in locating facilities and services, due to limitations in indoor GPS accuracy and cellular coverage.
Innovation Solution
Implementing a radio frequency locating system with wearable location devices that enable bi-directional communication, using RFIDs and UWB transceivers to provide precise location tracking and emit light or display images to guide users, while also allowing service requests and congestion management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS and cellular-based location systems are used, then device complexity is reduced, but measurement precision deteriorates in indoor and crowded environments
Solution Approach 1:
The patent introduces wearable location devices as intermediary components between users and the location system. These devices contain transceivers that communicate with base stations, serving as mediators to achieve precise indoor location tracking without relying on GPS. The wearable device acts as an intermediary that bridges the gap between the user and the complex infrastructure, maintaining measurement precision while managing device complexity at the user端.
Solution Approach 2:
The patent replaces GPS satellite-based electromagnetic positioning with a terrestrial radio frequency positioning system using wearable devices and base stations. This substitution eliminates dependence on satellite signals that fail indoors, providing continuous location tracking in crowded venues by using local RF communication infrastructure instead of space-based systems.
2Adaptability or versatility
If traditional unidirectional location monitoring is implemented, then device complexity is minimized, but adaptability deteriorates as users cannot request services or provide feedback
Solution Approach 1:
The wearable location device is designed with multi-functionality, serving both as a location tracker and a communication interface. It can receive instructions from the system (e.g., navigation guidance) and transmit service requests (e.g., restroom location, emergency help). This universal design allows a single device to handle multiple functions including positioning, navigation, and service interaction, thereby improving adaptability without proportionally increasing complexity.
Solution Approach 2:
The system implements bi-directional feedback loops where users can request services and receive responses through the wearable device. The device transmits user requests to the system and receives guidance or service confirmations back. This feedback mechanism enhances adaptability by allowing real-time interaction, while the automated processing keeps the communication system complexity manageable.
3Productivity
If detailed location tracking is implemented to reduce wait times, then productivity is improved, but loss of information increases due to privacy concerns
Solution Approach 1:
The system applies local quality by processing location data in a distributed manner. Base stations and local servers handle position calculations and service matching locally, transmitting only necessary aggregated information to central systems. This approach improves service efficiency through real-time local processing while minimizing privacy information loss by avoiding centralized collection of detailed personal location histories.

AI summary
An example disclosed method of receiving first blink data from a first tag, the first tag carried by a wearable location device associated with a monitored individual having a restricted region; determining tag location data based on the first blink data, the tag location data indicative of the monitored individual locations of the monitored individuals; determining if the monitored individual location is within the restricted region; and when the monitored individual location is within the restricted region: identifying a second tag associated with a security person in proximity to the monitored individual location; alerting the security personnel via the second tag as to the monitored individual being located in the restricted region.
