Solution Overview

Problem

Conventional navigation systems often display both traffic congestion and parking space information simultaneously on a map, leading to information overload that complicates user comprehension.

Innovation Solution

A map display system that dynamically switches between displaying traffic congestion icons and on-street parking space icons based on the distance to the destination, using a threshold value to determine when to switch from congestion icons to parking space icons, allowing users to input the switch manually.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If both traffic congestion icons and on-street parking space icons are displayed simultaneously on the map, then comprehensive information is provided, but information overload occurs making it difficult for users to obtain required information

Engineering Contradiction:
Improveamount of information displayedVSAvoiduser comprehension
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The display system dynamically switches between traffic congestion icons and on-street parking space icons based on the vehicle's distance to the destination. When the distance exceeds a first threshold, traffic congestion icons are displayed; when the distance is within the threshold, on-street parking space icons are displayed. This dynamic adaptation prevents information overload while ensuring relevant information is always visible.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different types of icons are displayed in different spatial contexts based on the vehicle's position relative to the destination. The system applies local quality by making the display content dependent on the specific situation (distance to destination), showing traffic congestion information when far away and parking space information when close, thereby optimizing user comprehension for each context.

Inventive Principle:
Principle #3Local quality

2Loss of information

If traffic congestion icons are always displayed on the map, then traffic information is continuously provided, but the map becomes cluttered when the vehicle is near the destination

Engineering Contradiction:
Improvetraffic information availabilityVSAvoidmap display complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system dynamically adjusts the displayed information based on the vehicle's distance to the destination. A display control unit switches from showing traffic congestion icons to showing on-street parking space icons when the distance falls within a first threshold value, reducing map clutter while maintaining relevant information availability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system prepares for the transition by monitoring the distance to the destination in advance. When the distance approaches the first threshold, the system proactively switches the displayed icons from traffic congestion to on-street parking spaces, ensuring the map remains uncluttered before the vehicle actually arrives at the destination area.

Inventive Principle:
Principle #10Preliminary action

3Loss of information

If on-street parking space icons are always displayed on the map, then parking information is continuously provided, but important traffic congestion information may be missed when the vehicle is far from the destination

Engineering Contradiction:
Improveparking information availabilityVSAvoidtraffic information awareness
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The display system dynamically adapts the type of icons shown based on the vehicle's distance to the destination. When the distance exceeds a first threshold, traffic congestion icons are displayed to maintain traffic information awareness. When the distance is within the threshold, the system switches to displaying on-street parking space icons to ensure parking information availability near the destination.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system applies local quality by making the display content context-dependent on the vehicle's position. Different information types are prioritized in different spatial contexts: traffic congestion information is emphasized when far from the destination, while parking space information is emphasized when close, optimizing ease of operation for each situation.

Inventive Principle:
Principle #3Local quality

AI summary

There is provided a technique that can prevent too much information from being displayed. A map display system includes a current location obtaining part that obtains a current location of a vehicle; a destination obtaining part that obtains a destination of the vehicle; a map information obtaining part that obtains map information; a map display part that displays, based on the current location and the map information, a map including the current location and a traffic congestion icon on a display part, the traffic congestion icon indicating traffic congestion information of a road; and a display control part that performs deletion of the traffic congestion icon and display of an on-street parking space icon on the map, when a distance between the current location and the destination reaches less than or equal to a first threshold value, the on-street parking space icon indicating a parking space on a street.
