Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices in vehicles lack the ability to differentiate between drivers and passengers, leading to inappropriate information being provided to users based on their roles within the vehicle.
Innovation Solution
An electronic device equipped with a sensor module to detect movement, a communication module to receive steering angle data, and a control module to determine whether the user is driving, allowing for the transmission of specific information based on the user's role.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If electronic devices in vehicles provide information to all users, then information coverage is improved, but information relevance deteriorates because different roles (driver/passenger) require different information
Solution Approach 1:
The electronic device automatically identifies the user's role (driver or passenger) by analyzing movement information and steering angle data without manual input. The system self-determines whether the user is operating the vehicle based on objective sensor data, eliminating the need for manual role selection or complex configuration settings.
Solution Approach 2:
The patent replaces manual role identification (mechanical/systematic approach) with automated sensor-based detection. Instead of requiring users to manually indicate their role or using complex camera/face recognition systems, the invention uses movement sensors and steering angle data to automatically determine user role through objective physical measurements.
2Measurement precision
If the system uses multiple sensors and data sources to accurately determine user role, then determination accuracy is improved, but device complexity increases
Solution Approach 1:
The electronic device utilizes existing multi-functional components (movement sensors and steering angle sensors) that serve multiple purposes. The movement information detects both device motion and user behavior patterns, while steering angle data indicates vehicle operation status. By combining these existing sensors, the system achieves accurate role determination without adding dedicated hardware.
Solution Approach 2:
The system uses movement information as an intermediary to infer user role. Rather than directly detecting whether the user is driving, the system analyzes movement patterns (acceleration, orientation changes) that correlate with driving behavior. This intermediary approach enables indirect but accurate role determination using available sensor data.
