Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for obtaining accurate location information for online users are limited in accuracy and difficult to control, especially at valuable locations, which hinders effective ad targeting and content personalization.
Innovation Solution
A system that gathers geographic information from mobile devices using various wireless radios like cellular, GPS, Bluetooth, and Wi-Fi, and integrates this information into user profiles to deliver relevant advertisements by tying real-world locations with virtual leads, utilizing geofencing and geolocation beacons to enhance targeting accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS triangulation is used to obtain geographical location, then measurement precision is improved, but device complexity and user activity requirements increase
Solution Approach 1:
The patent combines multiple location determination methods (IP address geolocation, GPS triangulation, cellular tower triangulation, Wi-Fi positioning) into a unified location tracking system. This allows the system to achieve accurate geographical location measurement without requiring the device to actively use any single method, as multiple passive and active methods are merged together to provide comprehensive location data.
Solution Approach 2:
The system implements a universal location tracking approach that works across different device states (active and inactive). By making the system multi-functional to handle various location determination methods and device states, it achieves accurate geolocation without being constrained by device activity requirements of any single method.
2Device complexity
If IP address geolocation is used, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent merges passive IP address geolocation with more precise active methods (GPS, cellular triangulation, Wi-Fi positioning) into a composite location determination system. This combination allows the system to maintain simplicity while achieving high measurement precision by layering multiple methods together.
Solution Approach 2:
The system uses an intermediary approach where less precise methods (IP address geolocation) provide initial location context, which is then refined by more precise methods (GPS, cellular triangulation) when available. This intermediary layering resolves the contradiction between simplicity and precision.
3Measurement precision
If multiple wireless radios are used to gather location information, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The system dynamically selects and activates different wireless radios and location determination methods based on current conditions, device state, and required precision levels. Rather than continuously using all radios, the system adapts its energy consumption profile to match the actual location tracking needs, resolving the contradiction between precision and energy use.

AI summary
A system receives geographic information from devices to determine and deliver relevant advertisements or personalized content for consumers. This ties a user's real-world location, with virtual leads (e.g., advertisements). The system uses geographical information gathered by mobile devices and saves the geographical information to consumer profiles. For example, the system can use different wireless radios present on mobile devices to gather different types of geographical information. Some radios include cellular, Bluetooth, global positioning system (or GPS), Wi-Fi, near field communications (or NFC), and other radios.
