Solution Overview

Problem

Existing image display devices require users to re-perform plotting when the coordinate system is displaced, leading to inefficiencies in maintaining plotted points' positions on the image.

Innovation Solution

An image display device with a plotting unit, data storage for plotted points, a graph display control unit, and a unit that updates plotted points' coordinates based on coordinate system displacements, ensuring plotted points remain in their original positions even after the coordinate system is moved.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the coordinate system is displaced on the image display region, then the display range of the coordinate system is improved, but the plotted points are shifted from their original positions on the image

Engineering Contradiction:

Improvedisplay range of coordinate systemVSAvoidposition accuracy of plotted points

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The system stores the coordinate values of plotted points in advance in a plotted point data storage unit. When the coordinate system is later displaced, the pre-stored coordinate values are retrieved and used to recalculate the plotted point positions, eliminating the need for re-plotting and maintaining position accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes the coordinate values of plotted points based on the displacement amount of the coordinate system. By adjusting the parameter (coordinate values) according to the coordinate system's displacement, the plotted points maintain their original positions on the image despite the coordinate system movement.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If the coordinate system is displaced on the image display region, then the coordinate system can be repositioned, but time and effort are required to re-perform plotting on the image

Engineering Contradiction:

Improvecoordinate system repositioningVSAvoidtime to re-perform plotting

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system creates a copy of the plotted point data by storing coordinate values in the plotted point data storage unit. When the coordinate system is displaced, this copied data is retrieved and used to regenerate the plotted points, eliminating the need to re-perform the plotting process and saving time.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The coordinate values of plotted points are stored in advance before any coordinate system displacement occurs. This preliminary storage of data enables rapid retrieval and reuse when the coordinate system is repositioned, eliminating the time-consuming re-plotting process.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If plotted points are stored with coordinate values in the coordinate system, then the plotted points can be retrieved, but the plotted points shift when the coordinate system is displaced

Engineering Contradiction:

Improvedata retrieval of plotted pointsVSAvoidposition accuracy of plotted points

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The system dynamically changes the coordinate values of plotted points based on the displacement of the coordinate system. By adjusting these parameters (coordinate values) in response to coordinate system movement, the plotted points maintain their original positions on the image while still being retrievable from storage.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system uses the displacement amount of the coordinate system as feedback to recalculate and adjust the coordinate values of plotted points. This feedback mechanism ensures that plotted points maintain their correct positions on the image after coordinate system displacement by compensating for the displacement through coordinate value adjustment.

Inventive Principle:

AI summary

An image display device includes a display unit, a graph display control unit, a display range displacement unit, a plotted point change unit and a graph update control unit. The graph display control unit displays an approximate graph for plotted points on an image display region to which a coordinate system is set. The display range displacement unit displaces a display range of the coordinate system with an image in the image display region fixed. Responding to the display range being displaced, the plotted point change unit changes coordinate values of the plotted points in accordance with displacements of the display range to maintain positions of the plotted points before and after the display range being displaced, and updates display of the plotted points, and the graph update control unit updates a content displayed by the graph display control unit.
