Solution Overview

Problem

Current traffic information display systems increase driver distraction by requiring drivers to sift through lengthy lists of traffic events, making it difficult to identify new versus read or updated information, leading to increased mental workload and potential confusion.

Innovation Solution

A traffic information display system that includes a user receiving status determining unit to categorize and visually indicate traffic information using graphical elements such as colors or icons, allowing drivers to easily distinguish between new, read, and updated traffic events, thereby reducing search time and confusion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If traffic information is displayed in a detailed list format, then information completeness is improved, but driver distraction increases

Engineering Contradiction:
Improveinformation completenessVSAvoiddriver distraction
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent applies color coding to differentiate between new traffic information (highlighted in a distinct color) and already read information (displayed in a different color). This allows drivers to quickly identify and focus on new information without needing to read through the entire list, thereby maintaining information completeness while reducing driver distraction.

Inventive Principle:
Principle #32Color changes

2Loss of information

If all traffic information is displayed without filtering, then information completeness is improved, but search time increases

Engineering Contradiction:
Improveinformation completenessVSAvoidsearch time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

By using color coding to mark new traffic information, drivers can immediately identify what needs their attention without scanning through the entire list. This visual differentiation significantly reduces search time while ensuring no information is lost.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent segments traffic information into new information (highlighted) and already read information (non-highlighted). This segmentation allows drivers to quickly focus on only the relevant new information, reducing search time while maintaining completeness of the displayed information.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If traffic information is displayed without visual indicators, then display simplicity is improved, but information distinguishability worsens

Engineering Contradiction:
Improvedisplay simplicityVSAvoidinformation distinguishability
Core Design Contradiction:
Device complexityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent uses color coding as a simple visual indicator to distinguish between new and already read traffic information. This approach maintains display simplicity while significantly improving information distinguishability, allowing drivers to quickly identify new information without complex interfaces.

Inventive Principle:
Principle #32Color changes

AI summary

A traffic information display system (1) comprises a traffic information processing unit (4) adapted to receive traffic information data which are transmitted in multiple cycles and to generate at least one portion of traffic information (41, 61, 81) from the traffic information data which is indicative of a traffic event, and a displaying unit (10) coupled with the traffic information processing unit (4) and which is adapted to display the at least one portion of traffic information (41, 61, 81). The displaying unit (10) includes a user receiving status determining unit (13) which is adapted for assigning a category (101 - 103) of a plurality of categories to the at least one portion of traffic information (41, 61, 81), the plurality of categories being indicative of different user receiving statuses of traffic information. The displaying unit (10) is adapted for displaying at least one graphical element (55, 65; 75, 85) which is associated with the at least one portion of traffic information (41, 61, 81), wherein the at least one graphical element (55, 62) is indicative of the assigned category of the at least one portion of traffic information (41, 61, 81). Accordingly, the system may reduce driver distraction when searching for interesting traffic messages.
