Electronic Device for Safe Driving via Pedestrian Alert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic systems for safe driving support in intelligent transport systems lack efficient communication mechanisms to alert drivers and pedestrians about potential collisions, especially in dynamic environments like intersections, where real-time information exchange is crucial for ensuring safety.
Innovation Solution
An electronic apparatus that facilitates road-to-vehicle, inter-vehicle, and pedestrian-to-vehicle communication by exchanging information about traffic lights, highway regulations, vehicle positions, and pedestrian states, using a mobile device with sensors and communication protocols like Bluetooth and Wi-Fi, to support safe driving decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time communication between electronic devices, vehicles, and pedestrians is implemented, then safety and collision prevention are improved, but system complexity and communication overhead increase
Solution Approach 1:
The system segments communication into different types (safety-related vs. non-safety-related) and handles them through different mechanisms. Safety-related information is prioritized and transmitted with higher reliability, while non-critical communications use standard protocols. This segmentation allows the system to maintain high safety standards without requiring all communications to meet the same complex requirements.
Solution Approach 2:
The electronic device acts as an intermediary between pedestrians and vehicles, receiving information from both parties and relaying critical safety information. This intermediary role simplifies the direct communication requirements between pedestrians and vehicles while maintaining safety through the mediation of the electronic device that can prioritize and filter communications.
2Measurement precision
If frequent safety message monitoring and transmission is performed, then collision detection capability is improved, but energy consumption increases
Solution Approach 1:
The system performs safety message monitoring and transmission periodically rather than continuously. The periodicity is dynamically adjusted based on environmental factors such as vehicle proximity, pedestrian movement detection, and location context. This allows the system to maintain adequate collision detection capability while reducing energy consumption during low-risk periods.
Solution Approach 2:
The monitoring and transmission frequency is made dynamic rather than static. The system adjusts the periodicity of safety communications based on real-time environmental conditions, increasing frequency when collision risk is high and reducing it when the environment is safe. This dynamic adaptation optimizes the balance between detection capability and energy usage.
3Reliability
If comprehensive information exchange about traffic lights, regulations, and positions is implemented, then safe driving support is improved, but communication overhead and data processing requirements increase
Solution Approach 1:
The system applies different information exchange strategies based on local conditions and device roles. Not all devices exchange all types of information at all times. The electronic device selectively communicates specific information types (such as pedestrian presence, position, and movement) to relevant parties based on the current situation, reducing unnecessary communication overhead while maintaining comprehensive safety support where needed.

AI summary
An electronic apparatus comprises an indoor determiner and a notification determiner. The indoor determiner performs an indoor determination for determining whether or not a user of the electronic apparatus is located in an indoor. The notification determiner performs determination processing for determining whether or not the electronic apparatus transmits a notification outside the electronic apparatus based on a result of the indoor determination.
