Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current sound source position specifying devices cannot display sound transmission positions on a map, limiting their effectiveness in reducing accidents and aiding the hearing-impaired in locating sound sources.

Innovation Solution

A position information providing device and method that superimpose icons representing sound data transmission positions on a map, using a display control portion to visualize sound data transmission positions based on sound position information, with optional features like animated icons for immovable objects and priority display for moving sound sources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If sound source position specifying device is used to obtain direction and distance information, then sound source position can be specified, but the information cannot be displayed on a map

Engineering Contradiction:

Improvesound position informationVSAvoidvisual confirmation of sound position

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent transforms sound position information from abstract directional and distance data into a two-dimensional map representation. By projecting the sound source position onto a map plane and displaying it as an icon at the corresponding location, the system enables visual confirmation of sound positions that were previously only available as directional and distance measurements.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If sound data is obtained from multiple sound sources, then comprehensive sound information is available, but it becomes difficult to determine which sound has influence on the hearer

Engineering Contradiction:

Improvesound dataVSAvoidsound influence determination

Core Design Contradiction:

Quantity of substanceVSDifficulty of detecting and measuring

Solution Approach 1:

The patent segments the complex sound environment by extracting and identifying individual sound sources from the mixed sound data. Each sound source is separately analyzed to determine its position, type, and characteristics, allowing the system to evaluate which specific sounds have influence on the hearer rather than treating all sounds as a single undifferentiated mixture.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent uses visual differentiation (analogous to color changes) by displaying different types of sound sources as distinct icons or visual markers on the map. This allows users to quickly identify and distinguish between different sound sources and their relative positions, making it easier to determine which sounds are relevant or influential.

Inventive Principle:

Principle #32Color changes

AI summary

A position information providing device includes a display control portion which controls, based on sound position information showing sound data transmission positions, the display of a map display screen where icons showing the sound data transmission positions are superimposed on a map.
