Solution Overview
Problem
Existing technologies face challenges in cost-effectively and efficiently transmitting large amounts of data to mobile electronic display devices, such as e-readers and smartphones, especially in areas with limited cellular coverage, while minimizing battery consumption and ensuring secure content delivery.
Innovation Solution
A method utilizing commercial or private broadcast radio transmitters with AM or FM receivers for one-way data transmission, combined with hybrid network technologies like cellular, Wi-Fi, and Bluetooth, to provide secure, cost-effective, and energy-efficient data delivery, including encryption and authentication systems for authorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cellular networks are used to transmit large amounts of data to mobile devices, then data transmission capability is improved, but battery consumption increases and cost increases
Solution Approach 1:
The patent replaces cellular network transmission with radio frequency broadcast transmission. The mobile display device uses a radio receiver instead of a cellular modem to receive content, substituting the mechanical/electronic system (cellular communication) with a different physical system (radio frequency reception) that consumes less battery power and provides broader coverage.
Solution Approach 2:
The patent makes the broadcast radio system capable of serving multiple functions: it can transmit news content, weather information, stock quotes, and other data services simultaneously over a wide area. The single broadcast infrastructure serves numerous devices and multiple content types, achieving multi-functionality that reduces overall system complexity and energy consumption.
2Productivity
If cellular networks are used to transmit large amounts of data to mobile devices, then data transmission capability is improved, but cost increases
Solution Approach 1:
The patent replaces expensive cellular data transmission with free or low-cost radio frequency broadcast transmission. By utilizing the radio receiver and antenna already present in mobile devices, the system eliminates costly cellular data charges while maintaining robust data transmission capability for content delivery.
3Use of energy by moving object
If broadcast radio transmission is used to deliver content, then battery consumption is reduced and coverage is extended, but data transmission speed and interactivity are limited
Solution Approach 1:
The patent employs preliminary action by pre-formating and pre-processing content into compact binary files optimized for broadcast transmission. Content is prepared in advance with compression and encoding that enables efficient reception and rapid display, compensating for the one-way broadcast nature by ensuring data is ready for immediate presentation upon receipt.
4Area of stationary object
If broadcast radio transmission is used to deliver content, then coverage area is extended, but security and authorized access control become more difficult
Solution Approach 1:
The patent introduces an intermediary authentication system that verifies device credentials before allowing content reception. The authentication server acts as a mediator between the broadcast transmission and the mobile display device, checking authorization tokens and granting or denying access to specific content based on subscription status, thereby securing the open broadcast channel.
5Device complexity
If one-way radio broadcast system is used, then device complexity is reduced and cost is lowered, but two-way communication capability is lost
Solution Approach 1:
The patent implements periodic action by having the mobile display device periodically wake from low-power mode to check for broadcast content updates, then return to sleep mode. This periodic activation allows the device to receive time-sensitive information (news, weather, stock quotes) without maintaining continuous communication, achieving a balance between responsiveness and energy conservation.
Data Source
AI summary
Digital content, particularly high volume digital content, such as newspapers or e-books are transmitted to an electronic device such as a handheld book reader over available bandwidth in a commercial FM radio station, private radio station, television station, or other one-way transmission system. A particular content item may be periodically rebroadcast along with other content on a rotating basis. GPS receivers and location-oriented databases may be used to allow the electronic device to find local broadcast outlets for the digital content when relocated to a new area. When no one-way transmission system is available or when packets of the high volume content are missing, a two-way communication system such as cellular (e.g. 3G or 4G systems), WiFi, WiMax, Bluetooth, etc. may be used to download all or part of the high volume content. Encryption schemes may be used to selectively authorize use of both electronic devices and content.
