Solution Overview

Problem

Current methods for exchanging insurance information after a vehicle collision are inefficient, dangerous, and prone to errors, especially in cases of hit-and-run accidents or when drivers are incapacitated.

Innovation Solution

Vehicle-based devices use wireless communication technologies, including 5G, to exchange vehicle identification and collision information securely, using public and private encryption keys, and certify collision information through digital signatures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If drivers exchange insurance information in person after a collision, then information exchange can occur, but safety risks increase and time is lost

Engineering Contradiction:

ImprovesafetyVSAvoidtime for information exchange

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical system of in-person information exchange with an automated wireless communication system. Vehicle-based devices automatically exchange insurance and collision information via wireless networks, eliminating the need for drivers to physically interact. This substitution resolves the contradiction by improving safety (no need to exit vehicles) while reducing time loss (automated exchange occurs immediately after collision detection).

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service by allowing vehicles to automatically exchange information without human intervention. After a collision is detected, the vehicle-based devices autonomously initiate wireless communication, transmit necessary information, and complete the exchange process. This resolves the contradiction by eliminating safety risks associated with drivers exiting vehicles while reducing time loss through automated processing.

Inventive Principle:

Principle #25Self-service

2Loss of information

If drivers manually exchange insurance information, then information can be transmitted, but accuracy decreases due to human error

Engineering Contradiction:

Improveaccuracy of information exchangeVSAvoidcomplexity of information exchange process

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent replaces manual information entry and exchange with automated wireless transmission systems. Vehicle-based devices automatically capture collision data and insurance information, then transmit it wirelessly without requiring drivers to manually write down or verbally communicate details. This resolves the contradiction by eliminating human error (improving accuracy) while the standardized automated process actually simplifies operations despite the technical complexity behind the scenes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates digital copies of insurance information and collision data that are automatically transmitted. Instead of drivers manually copying information from one form to another, the system digitally replicates and transmits the data wirelessly. This resolves the contradiction by ensuring accurate copying without human error while the automated copying process simplifies the overall operation for users.

Inventive Principle:

Principle #26Copying

3Reliability

If police assistance is provided for information exchange, then information exchange can occur in difficult cases, but resource consumption increases

Engineering Contradiction:

Improveinformation exchange completionVSAvoidpolice time and effort

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements self-service functionality where vehicles automatically exchange information without requiring police intervention. The system handles all information exchange tasks autonomously, including capturing collision data, transmitting insurance information, and confirming receipt. This resolves the contradiction by ensuring reliable information exchange completion through automated means while eliminating the consumption of police time and resources.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The wireless communication system acts as an intermediary between vehicles, replacing the need for police as intermediaries. The automated exchange system facilitates direct communication between involved parties, ensuring information exchange completion without requiring external law enforcement involvement. This resolves the contradiction by maintaining reliable exchange completion while eliminating the resource consumption associated with police assistance.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The described technology is generally directed towards wireless communications for vehicle collision response. Devices onboard vehicles can wirelessly exchange information in response to detecting a collision. Public encryption keys can be exchanged, and exchanged information can optionally be encrypted using a received public encryption key. Exchanged information can include vehicle identification information and collision information. The collision information can furthermore be certified using a vehicle's private encryption key.
