Mobile Device Message Relay for Vehicle Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers using mobile communication devices while operating vehicles often become inattentive due to incoming messages, leading to dangerous driving situations, as existing solutions rely heavily on personal responsibility and lack effective automation to manage distractions.
Innovation Solution
A mobile communication device integrated with motion sensors and a processor that determines the vehicle's state of motion and message importance to selectively relay messages to the driver, using a message class system to delay or format notifications based on driving conditions, reducing distractions and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the mobile communication device notifies the driver of all incoming messages, then the driver receives complete information, but the driver becomes distracted and inattentive
Solution Approach 1:
The patent segments messages into different categories (urgent vs. non-urgent) based on their importance level. Urgent messages are delivered immediately while non-urgent messages are delayed or suppressed, allowing the system to maintain information completeness for critical messages while reducing distraction from non-critical ones
Solution Approach 2:
The patent applies different notification strategies to different message types based on their urgency level. Important messages receive immediate notification while less important messages are handled differently, creating localized quality differences in message delivery based on their characteristics
2Object-affected harmful factors
If the mobile communication device delays non-urgent messages, then driver distraction is reduced, but message delivery time is extended
Solution Approach 1:
The system performs preliminary classification of messages upon receipt, determining their urgency level before delivery. This preliminary action allows the system to pre-determine the appropriate delivery timing, delivering urgent messages immediately while scheduling non-urgent messages for later, thus reducing distraction without causing excessive delay
3Object-affected harmful factors
If the mobile communication device converts messages to audio format, then driver attention is maintained on the road, but the driver cannot read the message content
Solution Approach 1:
The patent dynamically adapts the message delivery format based on driving conditions and message urgency. The system can switch between visual, audio, and haptic feedback modes depending on the situation, allowing the driver to receive message content through the most appropriate channel without being forced into a single format that may cause distraction
4Measurement precision
If the mobile communication device uses motion sensors to determine vehicle state, then message relay decisions are more accurate, but the device complexity increases
Solution Approach 1:
The patent leverages the multi-functionality of motion sensors already present in smartphones for various purposes (accelerometer for orientation, gyroscope for rotation, etc.). By utilizing these existing sensors for driving state detection, the system avoids adding separate dedicated sensor systems, thereby reducing overall device complexity while maintaining measurement precision

AI summary
A mobile communication device (104) and method of communication is disclosed. A communication signal having a message class (108) is received at the mobile communication device (104) conveyed by a vehicle (102). A message class (108) of the received communication at the mobile communication device (104) is obtained. A state of motion of the vehicle (102) is determined at the mobile communication device (104). The message class (108) and the determined state of motion is used to select an action to relay the communication to a driver of the vehicle (102).
