Wearable Warning Device for Vehicle Driver Alerting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current warning systems for vehicle drivers fail to promptly alert them to changes in traffic conditions, leading to delayed or missed detection of potentially dangerous situations, especially in high-concentration traffic or autonomous driving modes, as drivers must divert attention from the road to check dashboards, mirrors, and blind spots.
Innovation Solution
A wearable warning system connected to a detection system, which can be positioned externally or internally within the vehicle, using ultrasound sensors, Lidar, cameras, or infrastructure signals to transmit immediate alerts via light, sound, or vibrations directly to the driver, ensuring continuous awareness of changing traffic conditions without requiring them to look away from the road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the driver uses traditional warning systems (dashboard, mirrors, direct vision), then the driver can access information about traffic conditions, but the driver must divert attention from the road and take time to shift gaze, leading to delayed response
Solution Approach 1:
The patent introduces an intermediary warning device (wearable device on the driver's body) that mediates between the detection system and the driver's awareness. This intermediary delivers warnings directly to the driver without requiring the driver to actively check traditional instruments, thus reducing the time loss while ensuring information delivery.
Solution Approach 2:
The patent replaces the mechanical/visual system of dashboard indicators and mirror checks with a more direct warning mechanism (such as haptic feedback, audio signals, or visual indicators on the wearable device) that can alert the driver immediately without requiring physical gaze shifts or manual checks.
2Reliability
If the driver focuses continuously on the road, then the driver maintains situational awareness and safety, but the driver cannot access warning information from traditional systems in time
Solution Approach 1:
The wearable warning device acts as an intermediary that bridges the gap between the detection system and the driver's focused attention on the road. It delivers critical warning information directly to the driver without requiring the driver to break concentration, thus maintaining both safety and information delivery.
Solution Approach 2:
The warning system operates autonomously by detecting traffic conditions and automatically delivering warnings to the driver through the wearable device, eliminating the need for the driver to actively monitor or access warning systems, thus allowing continuous focus on the road while ensuring warning detection.
3Measurement precision
If the driver checks mirrors and blind spots frequently, then the driver can detect vehicles in blind spots, but the driver increases response time and reduces driving efficiency
Solution Approach 1:
The patent replaces the mechanical action of manually checking mirrors and blind spots with an automated detection system that uses sensors and processing to continuously monitor blind spots, delivering warnings only when necessary. This substitution maintains precise blind spot detection while eliminating the time-consuming manual checking actions, thus preserving driving efficiency.
Solution Approach 2:
The detection system operates continuously to monitor blind spots without requiring intermittent manual checks by the driver. This continuous automated monitoring maintains precise detection capability while allowing the driver to maintain continuous focus on the road, thereby preserving driving efficiency.
