Solution Overview

Problem

Existing alert systems for open vehicle doors fail to effectively alert oncoming traffic, increasing the risk of collisions.

Innovation Solution

A vehicle-mounted alert system with a hingedly coupled door and a visual alert mechanism, comprising light emitters and a reflective layer on the door, which activates when the door is open to warn approaching traffic.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a visual alert mechanism is added to the door, then the ability to alert oncoming traffic is improved, but the device complexity increases

Engineering Contradiction:
Improvecollision preventionVSAvoidalert system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The alert mechanism is integrated directly into the door structure itself, merging the warning function with the door component. This eliminates the need for separate external alert devices and reduces overall system complexity while maintaining effective traffic warning capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The door serves multiple functions: it provides vehicle access/enclosure and simultaneously acts as a traffic alert device when open. The alert mechanism is activated automatically by the door's open position, making the door a multi-functional component that warns traffic without requiring additional dedicated warning systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Illumination intensity

If the alert is always active, then visibility to oncoming traffic is improved, but energy consumption increases

Engineering Contradiction:
Improvealert visibilityVSAvoidenergy consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The alert mechanism operates periodically or conditionally based on door position rather than continuously. The alert is activated only when the door is in the open position and automatically deactivates when closed, providing visibility exactly when needed while minimizing energy consumption by avoiding continuous operation.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The alert system is self-regulating through the door's own position. The door's open/closed state automatically triggers or deactivates the alert mechanism without requiring external control systems, ensuring the alert provides maximum visibility during hazardous conditions while consuming minimal energy during normal closed-door operation.

Inventive Principle:
Principle #25Self-service

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

Effectively alerts oncoming traffic to the open door, reducing the risk of collisions by providing a visible warning when the door is extended into the roadway.

Implementation Method 1

An alert is coupled to the at least one door. The alert issues a visual alert when the at least one door is in the open position.

Methodology Applied
Scientific EffectLight emission: Light Emitting Diode

Implementation Method 2

A reflective layer is coupled to the second surface 32. The reflective layer enhances visibility of the panel 28 with respect to the oncoming traffic when the at least one door 16 is positioned in the open position.

Methodology Applied
Scientific EffectLight reflection: Reflection

AI summary

A hazard alert system includes a vehicle that has a back side and at least one door that is hingedly coupled to the vehicle. The at least one door is positionable in an open position having the at least one door extending outwardly from the vehicle. An alert is coupled to the at least one door. The alert issues a visual alert when the at least one door is in the open position. Thus, oncoming traffic is alerted to avoid the at least one door.
