Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If autonomous vehicles use only onboard sensors to recognize external situations, then the vehicle can operate independently, but the field of vision is limited and driving stability deteriorates

Engineering Contradiction:
Improvedriving stabilityVSAvoidlimited field of vision
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a mobile road traffic information providing apparatus as an intermediary device that collects road traffic information (traffic light signals, unexpected situations) and transmits it to autonomous vehicles. This mediator supplements the vehicle's onboard sensors, expanding the effective field of vision and improving driving stability without requiring direct modification to the vehicle itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If infrastructure is built to transmit road traffic information to autonomous vehicles, then driving stability improves, but the complexity and cost of infrastructure increases

Engineering Contradiction:
Improvedriving stabilityVSAvoidinfrastructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a mobile road traffic information providing apparatus that can move to different locations rather than being fixed. This dynamic approach allows the infrastructure to be deployed flexibly where needed, reducing the complexity of permanent infrastructure installation while still providing necessary road traffic information to improve autonomous vehicle driving stability.

Inventive Principle:
Principle #15Dynamics

3Reliability

If comprehensive road traffic information is collected and transmitted to all autonomous vehicles, then driving safety improves, but the quantity of data transmission and processing increases

Engineering Contradiction:
Improvedriving safetyVSAvoiddata transmission volume
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The mobile road traffic information providing apparatus transmits road traffic information (traffic light signals, unexpected situations) within a preset range around the vehicle, rather than broadcasting to all vehicles universally. This localized transmission approach maintains driving safety by providing relevant information to vehicles that need it, while reducing overall data transmission volume by limiting the broadcast area.

Inventive Principle:
Principle #3Local quality
