Solution Overview

Problem

Existing warning systems for vehicles, such as buses, fail to effectively alert drivers and other road users of pedestrians in hidden areas, leading to accidents, as they either do not cover the entire area around the vehicle or provide unclear warnings, and often result in false alarms from small objects.

Innovation Solution

A warning system with remotely detecting sensors and signaling means, including LEDs and a signal horn, that automatically alerts drivers and pedestrians of potential hazards by detecting objects within a specific vertical range and emitting signals from multiple sides of the vehicle, minimizing false alarms and ensuring visibility and audibility from various angles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sensors detect all objects in the vicinity of the vehicle, then detection coverage is improved, but false alarms increase due to small objects like animals or stones

Engineering Contradiction:
Improvedetection accuracyVSAvoidfalse alarm rate
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent applies local quality by configuring sensors to detect only within a specific vertical range (0.5-1.5 meters above ground), making the detection system selectively sensitive to pedestrian-height objects while ignoring smaller objects like animals or stones that fall outside this height range

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes the detection parameter from omnidirectional object detection to height-specific detection by setting a vertical range threshold, transforming the sensor's detection characteristics to match the typical height of pedestrians and exclude smaller objects

Inventive Principle:
Principle #35Parameter changes

2Use of energy by moving object

If warning signals are emitted only from the side where the object is detected, then energy consumption is reduced, but visibility to drivers on other sides of the vehicle is insufficient

Engineering Contradiction:
Improvesignal emission energyVSAvoidwarning visibility
Core Design Contradiction:
Use of energy by moving objectVSLoss of information

Solution Approach 1:

The patent segments the warning signal emission by placing signaling means at multiple locations around the vehicle (front, rear, and sides), allowing targeted signal emission from specific segments depending on where pedestrians are detected, thereby improving visibility without unnecessary energy consumption

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent adds spatial dimensionality to signal emission by distributing signaling means throughout the vehicle's perimeter rather than concentrating them at one location, enabling warnings to be visible from multiple directions and angles

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

AI summary

The present invention relates to a warning system mounted on a vehicle comprising detection means for detecting an object, and signalling means connected to said detection means, wherein said detection means are arranged to remotely detect an object in the vicinity of the vehicle and that said detection means is connected to said signalling means to automatically emit a signal that is detectable from at least one other side of the vehicle than the one where said object is present, and wherein said detection means (4) are arranged to avoid detecting objects lower than 0.5 m, preferably lower than 0.25 m from the ground.
