Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pedestrians face challenges in ensuring their safety while navigating public roads, as they need to be aware of vehicles and potential suspicious individuals, and there is a lack of effective devices to enhance their situational awareness and safety.
Innovation Solution
An environmental state notification device that includes an environment information acquisition unit, an environmental state recognition unit, and a notification unit, which acquires and analyzes data about the surrounding environment and the user's state to provide timely notifications through visual, auditory, or tactile means, enhancing pedestrian safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pedestrians rely on their own observation and awareness to ensure safety, then they maintain full control and awareness of their surroundings, but they cannot detect hazards beyond their visual range or process multiple threats simultaneously in time
Solution Approach 1:
The system divides hazard detection into multiple specialized sensors (camera for visual hazards, microphone for auditory hazards, GPS for location-based hazards) and processes them separately through dedicated analysis modules before integrating results for notification
Solution Approach 2:
The wearable device acts as an intermediary between the pedestrian and the environment, using sensors and processing units to detect, analyze, and notify about hazards that the pedestrian cannot perceive directly, extending human sensory capabilities
2Reliability
If pedestrians pay close attention to all surrounding elements to ensure safety, then they improve their situational awareness, but they experience increased mental load and reduced ability to react quickly to new threats
Solution Approach 1:
The system continuously monitors the environment in advance using sensors and predictive algorithms to identify potential hazards before they become immediate threats, allowing the pedestrian to take preventive actions ahead of time
Solution Approach 2:
The system provides real-time feedback through notifications (visual, auditory, or haptic) when hazards are detected, creating a closed-loop system that continuously adjusts awareness based on environmental conditions and pedestrian behavior
3Reliability
If multiple safe driving support devices are deployed on vehicles, then vehicle safety is improved, but vehicles without such devices remain vulnerable and pedestrians still face risks from undetected hazards
Solution Approach 1:
The wearable device serves multiple safety functions simultaneously: hazard detection, predictive analysis, real-time notification, and communication with external devices, making it universally applicable to all pedestrians regardless of vehicle equipment levels
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively enhances pedestrian safety by providing real-time awareness of potential hazards and improving situational awareness, allowing users to take appropriate actions to avoid dangers.
Implementation Method 1
a wave sensor that receives at least one of an electromagnetic wave or a sound wave from an environment surrounding the user and acquires the environment information data
Implementation Method 2
an emission unit that emits a detection electromagnetic wave or a detection sound wave
Implementation Method 3
the wave sensor may receive the reflected detection electromagnetic wave or the detection sound wave
Implementation Method 4
The position information acquisition unit may acquire the position information of the user from a satellite positioning system
Data Source
AI summary
A technology advantageous for improving safety of a user is provided. An environmental state notification device includes an environment information acquisition unit that is attached to a user and acquires environment information data indicating information regarding a surrounding environment of the user, an environmental state recognition unit that recognizes a state of a surrounding environment with respect to the user on the basis of the environment information data, and a notification unit that notifies the user according to the state of the surrounding environment with respect to the user recognized by the environmental state recognition unit.
