Driving Speed-Based Call Filtering for Mobile Phones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face safety concerns and distractions while handling mobile phone calls while driving, as existing hands-free devices do not adequately differentiate between important and unimportant calls, leading to potential accidents and missed important communications.
Innovation Solution
A method that connects a portable electronic device with a mobile phone to receive calls, calculates the vehicle's speed, and presents options to answer calls only when the speed is below a threshold or if the caller is an important contact, using Bluetooth technology and GPS for hands-free operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drivers use hands-free devices to take calls while driving, then drivers can free their hands to drive, but there remains a high level of distraction that can cause accidents
Solution Approach 1:
The system performs preliminary actions by pre-establishing speed thresholds and contact importance lists before calls occur. When a call arrives, the system immediately checks the current speed against stored thresholds and identifies important contacts from pre-loaded contact lists, enabling rapid decision-making without requiring the driver to manually assess safety conditions during the call.
Solution Approach 2:
The system provides feedback to the driver by presenting actionable information about incoming calls along with the current driving speed context. The interface shows whether the current speed allows for safe call handling based on pre-defined thresholds, enabling the driver to make informed decisions about whether to answer based on real-time speed feedback and call importance assessment.
2Reliability
If drivers cannot easily glance at the mobile phone, then drivers can maintain focus on the road, but the driver has no way of knowing who the caller is without first answering the call
Solution Approach 1:
The portable electronic device serves as an intermediary between the mobile phone and the driver. It receives call information from the mobile phone, processes the caller identification data, and presents this information to the driver through its own display interface. This intermediary device enables the driver to view caller information without needing to look at the mobile phone itself, maintaining road focus while obtaining necessary call information.
3Loss of information
If the system presents the option to answer all incoming calls, then important calls are not missed, but unnecessary disturbances occur when receiving unimportant calls
Solution Approach 1:
The system applies local quality by differentiating the handling of different calls based on their characteristics. Important calls from pre-identified contacts receive enhanced presentation and may be prioritized for answering, while unimportant calls from unknown numbers are filtered out or presented with less urgency. This selective approach allows the driver to focus on truly important communications while ignoring unnecessary disturbances.
Solution Approach 2:
The system changes the parameter of call presentation based on multiple factors including caller identity, call timing, and current driving speed. Important calls from known contacts trigger different presentation behaviors compared to unknown numbers. The system dynamically adjusts what information is presented and how urgent the call appears to be, based on changing parameters such as contact list matches and speed threshold comparisons.
4Reliability
If the system automatically filters out all calls above a speed threshold, then driving safety is maximized, but important calls from important contacts are incorrectly blocked
Solution Approach 1:
The system applies local quality by creating different handling rules for different call types. Instead of uniformly filtering all calls above a speed threshold, the system identifies important calls from pre-loaded contact lists and applies exception handling to those specific calls. Important calls maintain their delivery even when speed exceeds the threshold, while unknown calls are filtered. This localized differentiation ensures safety for unknown callers while preserving important communications.
Solution Approach 2:
The system performs preliminary action by pre-identifying important contacts and establishing speed thresholds before calls occur. The contact list and speed threshold parameters are prepared in advance, enabling the system to make informed exceptions for important calls without requiring real-time manual intervention. This preliminary setup allows the system to automatically distinguish between important and unimportant calls based on pre-established criteria.

AI summary
A method of responding to incoming calls while driving includes establishing a connection between an electronic device and a mobile phone to enable the electronic device to receive calls through the mobile phone. The electronic device receives position signals, calculates a speed at which the electronic device is moving, and thereby calculates a driving speed. The electronic device determines whether the driving speed is greater than a speed threshold when the mobile phone has an incoming call. The electronic device presents the user of the electronic device with an option to answer the incoming call when the driving speed is less than the speed threshold, and the electronic device presents the user with the option to answer the incoming call when the driving speed is greater than the speed threshold and when a phone number associated with the incoming call is present in a list of important contact numbers.
