Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pedestrian detection systems fail to prevent accidents as they only provide simple guidance, leading to increased safety risks when pedestrians are distracted by using wireless terminals while crossing streets, as they do not effectively ensure attention is diverted from screens during crossings.
Innovation Solution
A smart crosswalk safety system that uses bollard devices with pedestrian identification sensors, a camera to define a pedestrian identification area, and a beacon device to lock smartphone screens when a pedestrian enters the crosswalk, ensuring they focus on their surroundings during crossings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pedestrian detection apparatus provides simple guidance broadcasting, then the device complexity is low, but the safety effectiveness is insufficient to prevent accidents when pedestrians are distracted by wireless terminals
Solution Approach 1:
The system divides the crosswalk monitoring into multiple functional components: bollard devices with sensors for pedestrian detection, cameras for visual verification, beacon devices for terminal locking, and control devices for coordination. Each component handles a specific task, improving overall safety effectiveness while maintaining manageable complexity through modular design.
Solution Approach 2:
The control device acts as an intermediary that receives data from multiple sensors (bollard devices, cameras), processes this information, and coordinates the beacon devices accordingly. This intermediary layer integrates multiple functions and improves safety effectiveness without requiring direct complex interactions between all system components.
2Reliability
If the screen of the terminal is locked when a pedestrian enters the crosswalk, then the pedestrian's attention is diverted from the terminal to surroundings, but the device complexity increases due to multiple sensors and coordination systems
Solution Approach 1:
The system performs preliminary detection of pedestrian presence using bollard devices and cameras before the pedestrian actually enters the crosswalk. The beacon device is activated in advance to lock the terminal screen, ensuring the pedestrian's attention is diverted before the hazardous crossing situation begins, thereby improving safety effectiveness.
Solution Approach 2:
The bollard devices serve multiple functions: they detect pedestrians approaching the crosswalk, verify pedestrian presence through sensor arrays, and communicate with the control device. This multi-functionality reduces the need for separate dedicated components, improving safety effectiveness while managing system complexity.
3Measurement precision
If multiple sensors and devices are deployed to identify and track pedestrians, then the measurement precision of pedestrian location is improved, but the device complexity and cost increase
Solution Approach 1:
The system merges multiple detection methods into a unified pedestrian identification process: bollard devices with light sensors detect pedestrian presence, cameras capture visual confirmation, and these data streams are combined by the control device. This integration improves measurement precision of pedestrian location while managing complexity through coordinated multi-sensor operation.
Solution Approach 2:
The system continuously receives feedback from bollard sensors and cameras about pedestrian presence and location, processes this information through the control device, and adjusts beacon device activation accordingly. This feedback loop ensures high measurement precision for pedestrian tracking while maintaining efficient system operation through intelligent resource management.

AI summary
A smart crosswalk safety system for a pedestrian comprises bollard devices disposed in a sidewalk, each bollard device including a pedestrian identification sensor detecting a pedestrian, a camera photographing an area including the crosswalk, a beacon device transmitting a beacon signal toward the crosswalk when an operation signal is received from a control device, the control device generating an operation signal to drive the beacon device when the bollard device identifies a pedestrian who walks from the sidewalk toward the crosswalk and a pedestrian is identified to be present in the pedestrian identification area of an image captured by the camera, and a lock screen application installed in the pedestrian terminal of a pedestrian who crosses a street at the crosswalk to change screen of the terminal to a locked state when a beacon signal is received.
