Solution Overview

Problem

Current Advanced Driving Assistant Systems (ADAS) are limited to providing immediate hazard warnings and do not offer preemptive or anticipatory warnings for changing driving conditions, focusing primarily on what is directly in front of the driver, which can lead to missed threats from the sides or rear, and often overwhelm the driver with information.

Innovation Solution

A visual alert system that monitors changing driving conditions, anticipates potential threats, and directs the driver's attention by displaying warning lights in the same direction as the threat, with adjustable intensity based on time to collision and relative angular distance, using a control module, sensors, and driver tracking devices to illuminate lights strategically within the vehicle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If warning systems focus on what is happening directly in front of the driver, then immediate hazard detection is improved, but predictive value of threats from sides or rear is lost

Engineering Contradiction:
Improvehazard detection accuracyVSAvoidthreat prediction capability
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The warning system is segmented into multiple independent detection zones (front, rear, left, right) with dedicated sensors for each direction. This allows the system to maintain precise hazard detection in the forward direction while simultaneously monitoring other directions for predictive threat information, resolving the contradiction between focused detection accuracy and comprehensive threat prediction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a single-dimension (forward-only) detection approach to a multi-dimensional spatial monitoring system. By adding detection capabilities in rear, left, and right dimensions, the system maintains precise forward hazard detection while gaining predictive value from multi-directional threat assessment, eliminating the information loss about side and rear threats.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If warnings are delivered on an already crowded information center, then all hazard information can be displayed, but driver reaction time is reduced due to information overload

Engineering Contradiction:
Improveinformation display completenessVSAvoiddriver reaction time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The system extracts critical warning information from the crowded information center and presents it through dedicated, simplified visual indicators. By separating essential threat information from the general information display, the system maintains complete hazard information availability while reducing the cognitive load on the driver, thus preserving reaction time.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Different regions of the display system are assigned different functions with varying information densities. Critical warnings receive prominent, high-visibility presentation in dedicated areas, while less urgent information is displayed in peripheral or less prominent regions. This local differentiation allows complete information display while ensuring critical threats receive immediate attention without overwhelming the driver.

Inventive Principle:
Principle #3Local quality

AI summary

An alert system for a vehicle includes a tracking device, lighting system, control module, and sensor that can detect hazards. The tracking device can detect a driver's line-of-sight. The lighting system can be disposed about the vehicle and can emit light visible to the driver. The control module can determine a location of the hazard relative to the line-of-sight, and to operate the lighting system in a first mode in response to the hazard being outside of an angular threshold of the line-of-sight, and a second mode in response to the hazard being within the angular threshold. When in the first mode, a first region of the lighting system that corresponds to a general direction of the hazard can be illuminated. When in the second mode, a second region of the lighting system that corresponds to a specific location of the hazard is illuminated.
