Solution Overview

Problem

Existing location services are hindered by the high cost of global positioning system detectors, making location information sharing inaccessible to non-location aware communication devices.

Innovation Solution

A system and method where non-portable wireless access points determine and share their location coordinates with portable communication devices, allowing non-location aware devices to estimate their location by detecting the closest location-aware device and triangulating their position using wireless signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If global positioning system detectors are used to provide location services, then location information accuracy is improved, but device cost increases

Engineering Contradiction:
Improvelocation information accuracyVSAvoiddevice cost
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent introduces location-aware communication devices as intermediaries that possess GPS receivers and share their location information with non-location-aware devices. This mediator approach allows non-location-aware devices to access accurate location data without equipping them with expensive GPS receivers, thus resolving the contradiction between location accuracy and device cost.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent enables non-location-aware devices to obtain location information by copying or sharing location data from location-aware devices. Instead of each device independently purchasing and maintaining its own GPS receiver, the system allows devices to access location information through sharing mechanisms, reducing overall system cost while maintaining accuracy.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If location-aware communication devices share location information, then accessibility of location services is improved, but device complexity increases

Engineering Contradiction:
Improveaccessibility of location servicesVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal location sharing mechanism where location-aware communication devices can serve multiple functions: providing location services to themselves and sharing location information with non-location-aware devices. This multi-functionality approach increases accessibility without requiring separate dedicated systems, thereby managing complexity through consolidation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system employs feedback mechanisms where non-location-aware devices detect the presence and location information of location-aware devices, then request and receive appropriate location data. This feedback loop enables adaptive location service delivery, allowing the system to manage complexity through intelligent information exchange protocols rather than hardware proliferation.

Inventive Principle:
Principle #23Feedback

AI summary

A system that incorporates teachings of the present disclosure may include, for example, a portable communication device having a controller to request location information from one or more non-portable wireless access points, receive one or more location coordinates from the one or more non-portable wireless access points, determine which of the one or more non-portable wireless access points is closest to the portable communication device according to one or more wireless signals generated by the one or more non-portable wireless access points, and record the location coordinate supplied by the closest non-portable wireless access point. Each of the one or more non-portable wireless access points can determine its location coordinate with a location receiver. Other embodiments are disclosed.
