Smartphone Navigation Audio Diversion During Incoming Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smartphone navigation systems interrupt voice guidance during incoming calls, causing driver distraction and potential safety issues due to prioritization of phone functionality over navigation.
Innovation Solution
A method and apparatus that divert navigation guidance from a smartphone to a vehicle's audio system or display screen when an incoming call occurs, using a cradle, haptic commander, or radio head unit to ensure continuous route guidance and track vehicle location, allowing the navigation system to resume upon call completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the smartphone prioritizes phone functionality over navigation functionality, then the phone can handle incoming calls, but the voice guidance is interrupted causing driver distraction
Solution Approach 1:
The patent segments the audio output function by routing navigation voice guidance and phone call audio through different channels. The navigation guidance is diverted to the vehicle's audio system (speaker or headphones) while phone calls use the smartphone's built-in speakerphone or earpiece, allowing both functions to operate simultaneously without mutual interruption
Solution Approach 2:
The patent introduces an intermediary mechanism (the vehicle's audio system) to deliver navigation voice guidance. This intermediary allows the navigation audio to be transmitted independently from the smartphone's audio output, preventing phone calls from interrupting the guidance while maintaining both functionalities
2Adaptability or versatility
If the smartphone audio output is switched to the phone ringer during an incoming call, then the phone call can be received, but the voice guidance is interrupted
Solution Approach 1:
The patent implements dynamic audio routing that automatically adjusts based on the operational state. When navigation is active, voice guidance is routed to the vehicle audio system; when phone calls occur, the system dynamically switches phone audio to speakerphone/earpiece while maintaining navigation audio routing, creating flexible adaptability without interruption
Solution Approach 2:
The patent makes the audio output system multi-functional by enabling it to handle both navigation voice guidance and phone call audio through different output channels simultaneously. The vehicle audio system serves universal purposes for navigation, while the smartphone's built-in audio handles phone calls, creating a versatile audio architecture

AI summary
An apparatus and method diverts navigation guidance provided by a phone when an incoming call occurs to achieve uninterrupted route guidance. In one aspect, a communication system is integrated with the phone to divert the route guidance to a vehicle audio system or display screen when there is an incoming call. The communication system can also be integrated with a cradle, a haptic commander or a radio head unit, which can be communicatively connected with the phone and the vehicle, such that when the incoming call occurs, the route guidance information is transmitted from the phone to the vehicle audio system or display screen through the cradle, etc. Furthermore, the communication system can continuously track the vehicle location to restart the navigation system in the phone when the call is ended.
