Solution Overview

Problem

The increasing problem of insurance and consumer fraud in the automobile industry, particularly after natural disasters or accidents, where damaged vehicles are cosmetically repaired and resold, and substandard parts are used in repairs, making it difficult for insurance companies to detect fraudulent claims.

Innovation Solution

A system for testing automobiles and their parts by transmitting a test signal and analyzing the response to determine damage, using methods such as magnetic field disturbance detection and radio frequency identification (RFID) tags to create and compare baseline signals, ensuring the authenticity of the vehicle and replacement parts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If cosmetic repairs are performed on damaged vehicles to make them appear undamaged, then the vehicle appearance is improved, but fraud detection becomes more difficult

Engineering Contradiction:

Improvevehicle appearanceVSAvoidfraud detection difficulty

Core Design Contradiction:

ShapeVSDifficulty of detecting and measuring

Solution Approach 1:

The system performs preliminary actions by embedding unique magnetic signatures and RFID tags in vehicles and parts during manufacturing, and creating baseline records before any damage or repair occurs. This preliminary characterization enables later detection of unauthorized repairs by comparing current readings against the stored baselines, thus preventing fraud through advance preparation rather than post-repair inspection

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces magnetic field signatures and RFID tags as intermediary elements that serve as hidden identifiers and trackers within the vehicle and its parts. These intermediaries are invisible to consumers during cosmetic repairs but provide detectable signals to the system, allowing verification of part authenticity and detection of unauthorized repairs without affecting the vehicle's appearance

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If substandard parts are used in repairs to increase profit, then manufacturing cost is reduced, but vehicle safety and reliability deteriorate

Engineering Contradiction:

Improverepair costVSAvoidvehicle safety

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The system implements feedback by continuously monitoring the magnetic signatures and RFID responses of vehicle parts and comparing them against authenticated baseline records. When a part's signature deviates from the expected pattern or lacks proper authentication, the system generates an alert, providing real-time feedback to prevent installation of substandard parts and ensuring only approved components are used in repairs

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces traditional mechanical verification methods (visual inspection, physical tags) with magnetic field detection and RFID technology. This substitution enables non-intrusive, automated verification of part authenticity that cannot be easily circumvented, as the magnetic signatures are embedded within the part material itself rather than applied as external labels

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If comprehensive testing of vehicles and parts is implemented to detect fraud, then fraud detection accuracy is improved, but system complexity increases

Engineering Contradiction:

Improvefraud detection accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system achieves universality by using a single integrated approach that combines magnetic signature detection, RFID reading, and baseline comparison capabilities in one testing platform. This multi-functional system can verify both vehicle identity and part authenticity using the same hardware and software framework, reducing overall system complexity compared to separate specialized devices for each verification task

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The described embodiments contemplate a system, method and computer-readable medium with computer-executable instructions for accident notification. The novel system includes subsystems for testing an automobile, or a part of an automobile, and comparing the result of the test with a baseline result. The test may use various detectors, including radio frequency identification tags embedded in the paint of an automobile, magnetic variances caused by metal deformation, or electrical changes in a circuit. The test may be used for various purposes, including determining that an accident has occurred, verifying the authenticity of a repair part, or for processing an insurance claim.
