Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile electronic communication devices face challenges in providing reliable and secure complex messaging within shielded buildings, such as hospitals and police stations, due to limitations in existing pager and cellular phone systems, including difficulty in signal coverage and lack of centralized control and security features.
Innovation Solution
A mobile electronic communications device with a housing, memory, data entry mechanism, display, and multiple wireless transceivers configured to transmit and receive data using various protocols, along with a controller that detects available networks, prioritizes connections, and executes authentication processes, and a system comprising a user directory database, authentication authority, administration server, and messaging server for centralized management and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cellular telephones and smartphones are used for communication, then data exchanging capabilities are enhanced, but signal coverage becomes unreliable in shielded buildings
Solution Approach 1:
The mobile device incorporates multiple wireless transceivers that support different communication protocols (cellular, wireless LAN, short-range radio) allowing the device to adapt to various communication environments. This multi-functionality enables reliable communication in shielded buildings by switching between protocols depending on signal availability.
2Adaptability or versatility
If smartphones with complex functionality are deployed, then communication capabilities are enhanced, but device complexity and cost increase
Solution Approach 1:
The patent extracts and implements only the essential communication functions needed for the specific application (two-way messaging, alarm responses) while omitting unnecessary smartphone features. The mobile device is configured with specialized functionality for communication with the control system, separating essential communication capabilities from general-purpose smartphone features.
3Reliability
If centralized control and tracking of communications is implemented, then security and monitoring are improved, but system complexity increases
Solution Approach 1:
The control system serves as an intermediary between mobile devices and the network infrastructure. It centrally manages authentication, message routing, and communication tracking by receiving data from mobile devices via wireless transceivers and coordinating communication between devices and the network, thereby improving security without requiring complex modifications to individual devices.
4Adaptability or versatility
If multiple wireless transceivers with different protocols are integrated, then network adaptability is improved, but device complexity increases
Solution Approach 1:
The wireless communication capability is segmented into separate transceiver modules, each dedicated to a specific protocol (cellular, wireless LAN, short-range radio). Each transceiver handles a specific communication function independently, allowing the system to maintain protocol compatibility while managing complexity through modular architecture.

AI summary
A system for managing mobile electronic communications devices includes a user directory database configured to hold authentication data associated with at least one user, an authentication authority communicatively connected to the user directory database, an administration server configured to send and receive command messages with at least one mobile electronic communications device, a messaging server configured to send and receive communications messages with at least one mobile electronic communications device, and the authentication authority, administration server, and messaging server are configured to send and receive data via a data communications network. The authentication authority accepts or denies authentication data for a user received from at least one mobile electronic communications device, stores status information corresponding to authenticated users in the user directory database, and stores an association between each authenticated user and each mobile electronic device that sent authentication data for an authenticated user in the user directory database.
