Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Smart cars equipped with cameras and sensors face challenges in detecting long distances ahead or around corners due to camera placement, leading to incomplete or inaccurate environmental data for navigation and safety operations.

Innovation Solution

Implementing a data sharing system among smart vehicles, where each vehicle shares information about its visible environment with others, using a credit-based rating system and cryptographic verification to ensure trustworthiness, allowing for reciprocal data exchange to enhance situational awareness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If cameras are contoured into the vehicle body for aesthetic purposes, then the appearance of the vehicle is improved, but the detection distance and field of view are reduced

Engineering Contradiction:

Improvevehicle appearanceVSAvoiddetection distance

Core Design Contradiction:

ShapeVSLength of stationary object

Solution Approach 1:

The patent combines the sensors of multiple vehicles into a shared detection network. By merging detection resources across vehicles, the system achieves extended detection distance and improved field of view without requiring individual vehicles to have protruding cameras, thus maintaining aesthetic appearance while overcoming detection limitations.

Inventive Principle:

Principle #5Merging (Combining)

2Difficulty of detecting and measuring

If cameras are mounted on extending arms to increase detection distance, then the detection capability is improved, but the device complexity and aesthetic appearance are worsened

Engineering Contradiction:

Improvedetection capabilityVSAvoidcamera mounting structure

Core Design Contradiction:

Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

The patent creates a universal detection network where multiple vehicles contribute their sensing capabilities to a shared system. This multi-functional approach allows the fleet to achieve extended detection ranges without any single vehicle requiring complex extending arm structures, distributing the detection function across the entire vehicle network.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If each vehicle relies only on its own sensors, then the system simplicity is maintained, but the environmental data completeness is reduced

Engineering Contradiction:

Improvesystem structureVSAvoidenvironmental data

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The patent introduces a communication network as an intermediary that facilitates information exchange between vehicles. This mediator enables vehicles to share sensor data, overcoming individual detection limitations and achieving more complete environmental awareness while maintaining relatively simple individual vehicle structures.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A smart car system that exchanges information between different vehicles. An embodiment exchanges information one for the other. Another embodiment determines or sends information from one vehicle to the other, and then receives information from a different vehicle and keeps a score of a ratio between the amount of information that is set in an amount of information received. The information is checked for trust.
