Solution Overview

Problem

Existing inter-mobile body communication systems struggle to effectively transmit data with limited amounts when mobile bodies with different control attributes, such as varying levels of automatic driving, due to differing requested information items.

Innovation Solution

An information generation device that estimates the control attribute of nearby mobile bodies and generates transmission data prioritizing information items relevant to those attributes, including essential items regardless of control attributes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If transmission data amount is limited, then communication efficiency is improved, but information completeness deteriorates

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidinformation completeness
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent applies local quality by differentiating the treatment of information items based on their relevance to the receiver's control attributes. Essential information items relevant to the receiver's control attributes are transmitted with high priority, while less relevant items are transmitted with lower priority or omitted. This selective prioritization ensures that limited transmission data amounts are allocated to the most critical information, maintaining communication efficiency while preserving information completeness for the receiver's needs.

Inventive Principle:
Principle #3Local quality

2Reliability

If information is prioritized according to control attributes, then information effectiveness is improved, but transmission data amount required increases

Engineering Contradiction:
Improveinformation effectivenessVSAvoidtransmission data amount
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts and separates information items into distinct categories based on their relevance to control attributes. By identifying and extracting essential information items that are highly relevant to the receiver's control attributes, the system can prioritize their transmission. This extraction approach allows the system to focus transmission resources on the most critical information, improving information effectiveness while managing transmission data amount requirements through selective transmission of only the most relevant extracted items.

Inventive Principle:
Principle #2Taking out (Extraction)

3Device complexity

If all mobile bodies transmit the same information items, then communication simplicity is improved, but communication effectiveness deteriorates

Engineering Contradiction:
Improvecommunication simplicityVSAvoidcommunication effectiveness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent applies dynamics by making the information transmission strategy adaptive rather than static. The system dynamically adjusts the prioritization of information items based on real-time estimation of the receiver's control attributes. This dynamic adaptation allows the communication system to maintain simplicity in its basic operation while achieving high effectiveness by automatically adjusting what information is transmitted and at what priority, resolving the contradiction between simplicity and effectiveness.

Inventive Principle:
Principle #15Dynamics
