Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If virtual vehicle key sharing is implemented with readily available keys located within a vehicle, then ease of operation is improved, but security deteriorates leading to vehicle theft

Engineering Contradiction:
Improveease of vehicle accessVSAvoidvehicle security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a telematic device as an intermediary between the user and the vehicle systems. This device communicates with the vehicle's control units to authorize access and operation, preventing direct unauthorized use while maintaining convenient access for authorized users. The telematic device acts as a mediator that verifies user identity and transmission of control commands through the vehicle's telematic system.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical key systems with electronic telematic communication systems. Instead of physical keys that can be easily copied or lost, the system uses electronic authorization codes transmitted through telematic devices, providing both convenience and enhanced security through digital authentication and remote control capabilities.

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

2Device complexity

If traditional access control systems are used without telematic integration, then device complexity is reduced, but ability to monitor and manage vehicle usage deteriorates

Engineering Contradiction:
Improvesystem simplicityVSAvoidvehicle usage monitoring capability
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The telematic device performs multiple functions including access authorization, vehicle operation control, usage monitoring, and data transmission. By integrating these diverse functions into a single device that communicates with the vehicle's existing telematic system, the patent avoids adding multiple separate systems while comprehensive monitoring and control capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system continuously monitors vehicle usage parameters such as location, speed, and operational status, and transmits this data to remote servers. This feedback mechanism provides real-time information about vehicle usage, enabling centralized management and monitoring without requiring complex local monitoring infrastructure in the vehicle.

Inventive Principle:
Principle #23Feedback
