Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current satellite television systems lack the ability to determine a vehicle's location, resulting in the broadcast of emergency messages that may not be relevant to the specific area, as they do not differentiate between regions for displaying local channels and emergency information.

Innovation Solution

A communication system that includes a satellite broadcasting data, an emergency broadcasting source, and a mobile receiving device equipped with a location receiver, which compares the vehicle's location to the broadcast area and displays emergency information only when within the relevant region, using GPS or cellular tower-based systems for location determination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If emergency information is broadcast to all users in a wide area, then the coverage is maximized, but the relevance of the information to specific users deteriorates

Engineering Contradiction:

Improvebroadcast coverage areaVSAvoidrelevance of emergency information

Core Design Contradiction:

Area of stationary objectVSLoss of information

Solution Approach 1:

The system implements local quality by determining the mobile device's geographic location and selectively displaying emergency information based on whether the device is within the relevant broadcast area. This ensures that each user receives emergency information specific to their location rather than a blanket broadcast to all areas, thereby maintaining high information relevance while preserving wide broadcast coverage capability

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent introduces an intermediary mechanism (location determination system and area comparison logic) between the emergency information broadcast and the user display. This intermediary filters the broadcast information based on the user's location, allowing the system to receive all emergency broadcasts but only display those relevant to the user's current area, thus resolving the contradiction between wide coverage and information relevance

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If satellite systems display all rebroadcast local channels in a region, then the system complexity is reduced, but the precision of location-based channel selection deteriorates

Engineering Contradiction:

Improvesystem complexityVSAvoidlocation-based channel selection precision

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The system performs preliminary action by determining the mobile device's location and comparing it with the broadcast area boundaries before displaying emergency information or selecting local channels. This pre-comparison step enables the system to automatically select the appropriate regional content without requiring complex real-time decision-making, thereby maintaining relatively simple system architecture while achieving precise location-based channel selection

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If emergency messages are broadcast without location differentiation, then the broadcast simplicity is maintained, but the usefulness of the information to specific users deteriorates

Engineering Contradiction:

Improvebroadcast operation simplicityVSAvoidusefulness of emergency information

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system implements self-service by automatically determining the mobile device's location, comparing it with emergency broadcast areas, and selectively displaying relevant emergency information without requiring user intervention. The system autonomously filters and presents only the emergency information pertinent to the user's current location, maintaining broadcast operation simplicity while significantly improving the reliability and usefulness of the information received

Inventive Principle:

Principle #25Self-service

AI summary

A mobile wireless system (10) includes a transmitter such as a satellite (18) that broadcasts wireless signals such as boundaries for specific areas to a mobile receiving device (22). Mobile receiving device (22) may include an antenna (26) and a mobile receiving device (28). A locating receiver (50) is used to generate locating signals so that a determination may be made to the location of the mobile receiving device. When the location is outside an area of interest the area of interest may be extended to provide services to the mobile device. Emergency information is broadcast to a first area. An emergency announcement indicator is also broadcast into a first area and an area outside the first area. The location of the mobile receiving device is compared to the first area and the emergency information is displayed when the location is within the first area.
