Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users of dual-mode wireless communications devices cannot easily access and share current location information or view maps during an ongoing voice call without terminating the call, as conventional methods require launching a separate map application.

Innovation Solution

A method and device that enable displaying a map of the current location of a party on the phone screen during a voice call, using dual-mode wireless communications devices with separate voice and data channels, allowing for concurrent transmission and reception of location data without interrupting the call.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a separate map application is launched to view location information, then mapping functionality is accessed, but the voice call must be terminated

Engineering Contradiction:

Improveaccess to mapping informationVSAvoidvoice call continuity

Core Design Contradiction:

Ease of operationVSDuration of action of moving object

Solution Approach 1:

The patent merges the map application with the phone screen by embedding the map interface within the existing call display. This allows users to view location information and navigation instructions while the voice call remains active, eliminating the need to terminate the call to access mapping functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The phone screen serves multiple functions simultaneously: displaying call information (caller ID, call status) and displaying map information (location, directions) within the same interface. This multi-functionality allows the device to provide both voice communication and navigation services without requiring separate applications or terminating the call.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If location data is transmitted during voice call, then location information is shared, but device complexity increases

Engineering Contradiction:

Improveconcurrent voice and data transmissionVSAvoiddual-mode communication architecture

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the communication channels into separate voice and data pathways. The voice call uses one channel while location data and map updates use another channel, allowing both to operate simultaneously without interfering with each other. This segmentation enables concurrent voice and data transmission while managing complexity through structured separation of functions.

Inventive Principle:

Principle #1Segmentation

AI summary

A wireless communications device includes a radiofrequency transceiver having a wireless voice channel for transmitting and receiving voice communications and a separate wireless data channel for concurrently transmitting and receiving other data. The wireless communications device also includes a memory operatively connected to a processor for processing current location data received over the data channel from another communications device with which the wireless communications device is simultaneously communicating on the voice channel. The wireless communications further includes a display for displaying a phone screen during a voice call, the phone screen presenting call-related information. A map is displayed on the phone screen during the voice call, the map presenting a location current of the other communications device based on the current location data received over the data channel. Optionally, the map can also show the current location of the wireless communications device.
