Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite phones are used to provide communication in areas with limited network connectivity, then communication reliability is improved, but device cost increases significantly
Solution Approach 1:
The patent introduces a gateway device as an intermediary between mobile devices and cellular networks in areas with limited connectivity. This gateway acts as a mediator that receives communications from mobile devices and relays them through available network connections, providing reliable communication without requiring expensive satellite phone hardware.
2Ease of manufacture
If 2-way radios are used to provide communication in areas with limited network connectivity, then device cost is reduced, but communication richness and reliability deteriorate
Solution Approach 1:
The patent creates a universal communication system that can operate across multiple network types (cellular, Wi-Fi, other radio networks) through a single gateway device. This multi-functional approach allows the system to adapt to available network infrastructure, maintaining both cost-effectiveness and communication reliability by switching between different network types as needed.
3Area of stationary object
If multiple radio resources are managed separately to extend cellular coverage, then communication coverage is improved, but system complexity increases
Solution Approach 1:
The patent merges multiple discrete radio resources (cellular modems, Wi-Fi radios, other communication interfaces) into a single unified gateway device managed by one application processor. This consolidation extends communication coverage by utilizing multiple network types while reducing system complexity through centralized management and a single point of control.
Data Source
AI summary
The application describes an apparatus including a single application processor operably coupled to a non-transitory memory including instructions stored thereon. The apparatus also includes plural, discrete radio resources operably in communication with the single application processor. Each radio resource includes a modem operating on a network selected from at least one of LoRA, digital mobile radio and metro access network. In the apparatus, the single application processor is configured to execute the instructions of discovering the modem of each discrete radio resource. The single application processor is also configured to execute the instructions of assigning a TCP port to each discovered modem. In addition, the single application processor is configured to execute the instructions of creating an individualized session for each modem. Further, the single application processor is configured to execute the instructions of scanning an area experiencing limited connectivity for mobile equipment located a predetermined distance away from the single application processor.
