Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Vehicle-ramming attacks pose a significant threat due to the ease with which vehicles can be hijacked or controlled remotely, especially in crowded areas, and existing safety measures are inadequate to prevent such incidents.

Innovation Solution

An emergency stop system that allows non-drivers, such as pedestrians, to initiate a vehicle stop or slow down using a combination of signals from portable electronic devices, pressing sensitive parts on the vehicle, or specific sound patterns, requiring multiple independent confirmations to prevent misuse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the emergency stop system accepts signals from multiple users to stop the vehicle, then the system's ability to prevent vehicle-ramming attacks is improved, but the risk of false activation or misuse increases

Engineering Contradiction:

Improveprotection against vehicle-ramming attacksVSAvoidfalse activation or misuse

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary verification by checking whether multiple independent stop signals are received within a predetermined time window before activating the emergency stop. This preliminary action filters out false activations while allowing genuine emergency stops to proceed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by monitoring the sources and timing of stop signals, verifying that they come from multiple independent users within a specific time window. This feedback mechanism ensures that only legitimate crowd-sourced emergency stops are activated, preventing misuse while maintaining reliability.

Inventive Principle:

Principle #23Feedback

2Object-affected harmful factors

If the system requires multiple independent signals within a predetermined time window, then the prevention of misuse is improved, but the response time to stop the vehicle may be delayed

Engineering Contradiction:

Improvemisuse preventionVSAvoidvehicle stopping time

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system adjusts the time window parameter dynamically or optimizes it to balance between preventing misuse and ensuring rapid response. By carefully selecting the time window duration, the system prevents false activations from single users while ensuring that genuine emergency stops are activated quickly when multiple users independently signal danger.

Inventive Principle:

AI summary

There is provided a method to stop or slow down a vehicle in an emergency, said vehicle comprising an emergency stop system able to cause the vehicle to stop or slow down, the emergency stop system being able to receive stop signals from users that are not driving the vehicle, the method comprising the steps of a) the emergency stop system receiving a first signal to stop the vehicle, b) the emergency stop system immediately starting a timing procedure, c) the emergency stop system, within a predetermined time window, receiving a predetermined number of further signals to stop the vehicle, and d) the emergency stop system, if the required number of signals has been received, immediately causing the vehicle to stop or slow down.
