Solution Overview

Problem

Increased incidents of vehicles colliding with blocker vehicles at emergency scenes due to distracted drivers, posing risks to personnel and equipment.

Innovation Solution

A vehicle equipped with sensors and a control system that monitors the area in front of the vehicle, detects imperceptible objects due to visibility impairments, and generates a graphical representation for the operator to facilitate safe operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If blocker vehicles are used at emergency scenes to prevent approaching vehicles, then personnel and equipment are protected, but distracted drivers may collide with blocker vehicles causing damage and harm

Engineering Contradiction:

Improvesafety of personnel and equipmentVSAvoidcollision risk from distracted drivers

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary detection of distracted drivers using sensors (cameras, radar, LIDAR) before a collision occurs. The control system generates graphical representations of detected objects and displays them to the operator in advance, allowing proactive safety measures to be taken before the harmful collision event happens.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The graphical representation system acts as an intermediary between the sensor data and the operator. It processes raw sensor data into visual formats that enhance the operator's awareness of distracted drivers and potential collision risks, bridging the gap between detection and response.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If sensors and graphical display systems are added to the vehicle, then detection capability and safety are improved, but device complexity increases

Engineering Contradiction:

Improvedetection capabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The control system performs multiple functions using a single integrated architecture: it generates graphical representations of detected objects, displays them to the operator, and coordinates with other vehicle systems. This multi-functionality reduces the need for separate dedicated systems for each function, thereby managing complexity while maintaining high detection capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A vehicle includes a display positioned within the vehicle, at least one sensor positioned to facilitate (i) monitoring an area in front of the vehicle as the vehicle is responding to a scene and (ii) detecting an object in the area in front of the vehicle that is imperceptible to an operator because of a visibility-impairing condition, and a control system configured to generate a graphical representation of the area and the object for display to the operator on the display based on sensor data acquired by the at least one sensor to facilitate operation of the vehicle by the operator through the visibility-impairing condition.
