Solution Overview

Problem

Existing warning triangle devices face challenges in accurately determining the distance from a parked vehicle, especially in poor visibility conditions, and lack features for automatic assistance and enhanced safety and recognizability at night or in adverse weather.

Innovation Solution

Incorporating a distance measuring device and display on the warning triangle, along with automated activation mechanisms, GPS, and LED lighting elements that adjust brightness based on ambient conditions, to ensure precise placement and increased visibility, and a transmission unit for emergency calls.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If conventional passive reflective elements (cat's eyes) are used for visibility, then the warning triangle is recognizable when headlights hit it, but optical recognition at dusk and in the dark is insufficient

Engineering Contradiction:

Improvevisibility at dusk and in the darkVSAvoidoptical recognition sufficiency

Core Design Contradiction:

Illumination intensityVSReliability

Solution Approach 1:

The patent applies parameter changes by transitioning from passive reflective elements to active LED lighting elements that can dynamically adjust their illumination parameters. The control unit regulates the LED elements to provide active illumination during dusk and dark conditions, fundamentally changing the visibility parameter from passive reflection to active emission, thereby resolving the insufficiency of optical recognition in low-light conditions

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If distance estimation is performed manually in poor visibility conditions, then placement of the warning triangle can be attempted, but the uncertainty in determining actual distance increases significantly

Engineering Contradiction:

Improvewarning triangle placement processVSAvoiddistance determination accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent replaces the manual mechanical estimation method with an electronic distance measuring device that uses optical or electromagnetic principles. This substitution eliminates the uncertainty inherent in manual estimation by providing precise electronic measurement of the distance between the parked vehicle and the warning triangle, even in poor visibility conditions

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements feedback by displaying the measured distance information on a display device attached to the warning triangle. This feedback mechanism allows the person placing the triangle to see the actual distance measurement and adjust the position accordingly, ensuring precise placement at the required distance while maintaining ease of operation

Inventive Principle:

Principle #23Feedback

3Reliability

If automated assistance for medical care and technical assistance is integrated into the warning triangle, then comprehensive safety information can be transmitted, but the device complexity increases

Engineering Contradiction:

Improvesafety assistance provisionVSAvoidwarning triangle system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies universality by integrating multiple functions into a single warning triangle device. The transmission unit is designed to handle both medical care assistance information and technical assistance information through a unified communication system. This multi-functional approach increases safety assistance provision while managing device complexity through functional integration rather than separate systems

Inventive Principle:

Principle #6Universality (Multi-functionality)
