Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users find it difficult to easily identify specific facilities within complex indoor maps of large buildings like shopping malls, as existing indoor maps do not provide a simple and intuitive way to search for facility information.

Innovation Solution

A method and device that display a background map and indoor map on a screen, with a facility information search UI allowing users to select facility types, highlighting relevant facilities, and providing detailed information on demand.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If an indoor map displays various facilities in a large building, then the map provides comprehensive information, but users cannot easily identify specific facilities among the many facilities displayed

Engineering Contradiction:

Improvenumber of facilities displayedVSAvoiddifficulty of identifying specific facility

Core Design Contradiction:

Quantity of substanceVSDifficulty of detecting and measuring

Solution Approach 1:

The patent segments the indoor map display into multiple floors, allowing users to navigate and search for facilities floor by floor. This segmentation reduces the visual complexity by dividing the large building's facilities into manageable floor-specific sections, making it easier for users to locate specific facilities without being overwhelmed by the entire building's facility list.

Inventive Principle:

Principle #1Segmentation

2Loss of information

If the indoor map shows all facility types, then the information completeness is improved, but the search interface becomes complex and non-intuitive

Engineering Contradiction:

Improvecompleteness of facility informationVSAvoidsimplicity of search interface

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent implements preliminary action by providing a facility search function that allows users to pre-select facility types (such as restaurants, cafes, restrooms) before conducting the search. This pre-selection mechanism simplifies the interface by filtering out irrelevant facilities, enabling users to quickly find specific facility types without navigating through a complex display of all facility types in the building.

Inventive Principle:

Principle #10Preliminary action

3Loss of information

If the map displays detailed facility information, then the information value increases, but the interface becomes cluttered and harder to navigate

Engineering Contradiction:

Improvedetail level of facility informationVSAvoidinterface complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies dynamics by implementing an interactive search interface that adapts to user needs. When users select specific facility types through the search function, the map dynamically updates to display only relevant facilities with their locations marked on the indoor map. This dynamic filtering maintains information value while reducing interface clutter, as the display adjusts based on user preferences rather than showing all facilities simultaneously.

Inventive Principle:

Principle #15Dynamics

AI summary

A method of providing an indoor map search service, according to one embodiment of the present disclosure, may include: rendering and displaying, on a map screen, a background map and an indoor map of a point of interest (POI) on the background map; and displaying, in an area of the map screen, a facility information search user interface (UI) that facilitates a search for facility information about facilities included in the indoor map.
