Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional location-based services rely on infrastructure-level filtering, raising privacy concerns regarding user location knowledge, as they do not effectively manage message dissemination based on user movement within specific geographic regions.

Innovation Solution

A mobile computing device system that integrates a message receiver, navigation module, and dissemination unit to filter and disseminate location-based messages based on the device's projected route and geographic region intersections, using wireless communication and geospatial data to determine message relevance and timing.

VSEngineering Contradiction Analysis

1Productivity

If infrastructure-level filtering is used to manage location-based services, then message dissemination can be controlled at the source, but privacy concerns arise due to infrastructure knowledge of user location

Engineering Contradiction:

Improvemessage dissemination controlVSAvoidprivacy concern

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

Instead of having infrastructure filter messages based on user location (top-down approach), the patent inverts the approach by having mobile devices autonomously determine their own location and filter incoming broadcast messages locally (bottom-up approach). This inversion transfers control from infrastructure to end devices, eliminating privacy concerns while maintaining effective message filtering.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

Mobile devices perform self-service by autonomously determining their current location, comparing it with geographic regions associated with broadcast messages, and independently filtering which messages to display. This self-service capability eliminates dependency on infrastructure-level location tracking while achieving effective message dissemination control.

Inventive Principle:

Principle #25Self-service

2Loss of information

If all broadcast messages are disseminated to users, then complete information availability is achieved, but unnecessary data exposure increases and message relevance decreases

Engineering Contradiction:

Improveinformation availabilityVSAvoidunnecessary data exposure

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by having mobile devices pre-determine their current location and pre-compare it with the geographic regions associated with incoming broadcast messages before displaying them. This preliminary filtering action ensures that only relevant messages are presented to users, preventing unnecessary data exposure while maintaining complete information availability for relevant content.

Inventive Principle:

Principle #10Preliminary action

AI summary

Systems and methods for disseminating messages to a user via a mobile computing device are provided. In an embodiment, a route of the mobile computing device that includes at least a destination and one or more segments is determined, and one or more generally-broadcast messages, each corresponding to a geographic region, are received. A determination is made as to whether the mobile computing device, while traveling along the route to the destination, will traverse a particular geographic region associated with a particular generally-broadcast message of the one or more generally-broadcast messages; and if/when the mobile computing device will traverse the particular geographic region, the particular generally-broadcast message is disseminated, through the mobile computing device, to the user.
