Solution Overview

Problem

Existing facility display systems that utilize multiple databases often result in erroneous recognition of facilities due to differences in database content, leading to inconsistent output even when displaying information about the same facility.

Innovation Solution

A facility display data creating device and system that retrieves and combines facility information from multiple databases, sorting and displaying it based on distance from a predetermined position to ensure adjacent display of corresponding facilities, thereby preventing user confusion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If facility information is sorted and displayed in order of distance from a predetermined position, then the display follows a logical spatial sequence, but corresponding facilities from different databases may be separated and displayed non-adjacently, leading to user confusion

Engineering Contradiction:

Improvedisplay organizationVSAvoidfacility identification accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent segments the display into two distinct parts: a distance-based sorted list and a correspondence indication section. This allows the main list to maintain logical spatial ordering while a separate section explicitly shows which facilities correspond to each other, resolving the contradiction between organized display and accurate identification.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary element (correspondence indication such as matching reference numbers or identifiers) that links corresponding facilities from different databases. This intermediary allows users to trace the relationship between facilities even when they appear at different positions in the distance-sorted list, maintaining both spatial organization and identification accuracy.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If facility information from multiple databases is combined and displayed, then comprehensive facility data is provided, but inconsistencies in database content cause the same facility to appear with different information, leading to erroneous user recognition

Engineering Contradiction:

Improvedata source integrationVSAvoidfacility information consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies local quality by providing different types of information in different parts of the display: basic facility information (name, address, phone number) is shown consistently for all facilities, while correspondence indicators are selectively applied only to facilities that have matches across databases. This allows comprehensive data integration while maintaining consistency where it matters most for user recognition.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent uses visual differentiation (such as highlighting, bolding, or color-coding corresponding facilities) to draw attention to facilities that have counterparts in other databases. This visual cue helps users quickly identify which facilities are duplicates or related, preventing erroneous recognition while maintaining the comprehensive multi-database approach.

Inventive Principle:

Principle #32Color changes

3Reliability

If corresponding facilities are displayed adjacently regardless of distance order, then user recognition of corresponding facilities is improved, but the overall spatial logic of the display is disrupted

Engineering Contradiction:

Improvefacility correspondence recognitionVSAvoiddisplay spatial logic

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent segments the display functionality into two modes or sections: the primary list maintains distance-based spatial logic, while a separate correspondence indication mechanism (such as matching identifiers or a linked view) provides the adjacency information. This segmentation allows both spatial logic and correspondence recognition to coexist without conflict.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent resolves the contradiction by adding another dimension to the display - instead of rearranging the one-dimensional distance-sorted list, it adds a second dimension (correspondence indicators, cross-references, or linked annotations) that shows relationships without disrupting the original spatial ordering. This allows users to perceive both the spatial sequence and the correspondence relationships simultaneously.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A facility display data creating device is provided. The device includes: a first processing unit that retrieves a first facility information group from a first database; a second processing unit that retrieves a second facility information group from a second database; a third processing unit that determines whether any of facilities indicated by the first facility information group corresponds to any of the facilities indicated by the second facility information group; and a fourth processing unit that creates display data to display facility information by combining and sorting the first and second facility information groups in an order of distance from a predetermined position, and that creates the display data to display the facility information of the corresponding facilities adjacently to each other and independently of the order of distance on condition that the corresponding facilities are determined.
