Solution Overview

Problem

Existing methods for documenting the condition of motor vehicles, such as those used by vehicle hire and car-sharing companies, are either too complex and expensive or lack the necessary reliability for evidence, especially in scenarios where multiple locations need to be covered.

Innovation Solution

A method and system where an image generation device, coupled to a control device of the motor vehicle via a data link, captures images and generates a data stamp that includes vehicle-specific and environmental information, which is then digitally signed to create a stamped image that can be used as reliable evidence, with the image generation signal initiated by the control device to ensure security and authenticity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a complex apparatus with turntable and digital video camera is used to document vehicle condition, then measurement precision and reliability are improved, but device complexity and cost increase significantly

Engineering Contradiction:
Improvevehicle condition documentation precisionVSAvoiddocumentation system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses a digital camera to capture images of the vehicle, creating a visual copy of the vehicle's condition. This image-based copying approach replaces the complex mechanical turntable system while maintaining documentation capability. The images serve as faithful replicas of the vehicle state at specific moments, enabling condition assessment without physical manipulation of the vehicle.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical turntable system with an electronic/image-based documentation approach. Instead of mechanically rotating the vehicle on a turntable to capture all surfaces, the system uses digital cameras to photograph vehicle surfaces from various positions. This substitution eliminates complex mechanical infrastructure while achieving comparable documentation goals through electronic means.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If a complex turntable-based documentation station is installed at every return location, then documentation reliability is improved, but implementation cost and infrastructure requirements increase

Engineering Contradiction:
Improvedocumentation reliabilityVSAvoiddeployment feasibility
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent employs inexpensive digital cameras instead of expensive turntable-based documentation stations. The digital camera is a relatively cheap, portable device that can be easily deployed at multiple locations without requiring permanent infrastructure installation. This approach allows vehicle hire companies to document vehicle conditions at numerous return locations without the prohibitive costs associated with installing complex turntable systems at each site.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The documentation system enables operators to independently capture vehicle condition images using digital cameras without requiring specialized turntable equipment or complex setup procedures. The system is self-sufficient, allowing any operator at any return location to document vehicle conditions using standard digital imaging devices that are already widely available and easy to operate.

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If conventional digital camera images are used without additional verification, then cost-effectiveness is improved, but evidence reliability and authentication capability deteriorate

Engineering Contradiction:
Improvedocumentation cost-effectivenessVSAvoidevidence cogency
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent introduces a data stamp as an intermediary element that connects the image to the vehicle's control device. The data stamp contains authentication information and links the captured image to the specific vehicle and documentation event. This intermediary mechanism verifies that the image genuinely represents the documented vehicle without requiring complex verification procedures, thereby maintaining cost-effectiveness while significantly enhancing evidence reliability and legal admissibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If multiple images are captured without standardized triggering, then flexibility is improved, but data consistency and comparability worsen

Engineering Contradiction:
Improveimage capture flexibilityVSAvoidcondition assessment accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent implements a standardized triggering mechanism where the control device sends trigger signals to the digital camera based on predefined conditions such as vehicle location, door status, or inspection checkpoints. This feedback-based triggering ensures that images are captured at consistent, predetermined moments and positions during the vehicle return process. The standardized approach maintains flexibility in choosing which conditions trigger captures while ensuring that all captured images are comparable and suitable for consistent condition assessment across different vehicles and locations.

Inventive Principle:
Principle #23Feedback

AI summary

A system and method are provided to document the condition of a motor vehicle with an image generation device coupled to a control device of the motor vehicle via a data link. An image generation signal is initiated, which is present both at the control device of the motor vehicle and at the image generation device. The image generation signal triggers the generation of an image of the motor vehicle by the image generation device and triggers the generation of a data stamp at the control device. The data stamp is linked to the image.
