Solution Overview

Problem

Existing graph display devices require cumbersome operations to change the value of coefficients in functional expressions, necessitating multiple screen displays and resets, which is time-consuming and labor-intensive.

Innovation Solution

A graph display device with a touch panel and slider interface that allows users to easily change coefficient values within a functional expression by generating and operating sliders directly on the graph display, enabling immediate visualization of graph changes without needing separate setting screens.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If exclusive setting screens are displayed to change coefficient values, then coefficient values can be changed, but operational complexity and time consumption increase significantly

Engineering Contradiction:
Improvecoefficient value change operationVSAvoidtime for screen display and reset
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent merges the coefficient setting function directly into the graph display screen by adding sliders overlaying the graph area. This allows coefficient adjustment and graph visualization to occur simultaneously on the same screen, eliminating the need to switch between separate setting screens and graph screens, thereby reducing operational steps and time consumption.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The graph display screen is designed to serve multiple functions simultaneously: displaying the functional expression, showing the graph visualization, and providing coefficient adjustment controls through sliders. This multi-functional design eliminates the need for dedicated separate screens for each function, streamlining the user interface and reducing navigation time.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple screens are used for coefficient setting, then coefficient values can be adjusted, but device complexity increases

Engineering Contradiction:
Improvecoefficient adjustment capabilityVSAvoidscreen display system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the coefficient adjustment interface with the graph display interface into a single unified screen. The sliders are positioned to overlay or adjacent to the graph area, allowing users to adjust coefficients and view graph changes simultaneously without navigating between multiple screens, thereby reducing system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent adds a new dimension to the graph display screen by incorporating sliders as an additional interactive layer. Instead of using separate screens for coefficient adjustment, the sliders are integrated into the existing 2D graph display area, utilizing the screen space more efficiently and avoiding the need for additional display screens or complex screen switching mechanisms.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A graph display device includes an expression input unit, a graph display control unit, first and second display control units and a coefficient changed graph display control unit. The expression input unit recognizes a functional expression. The graph display control unit displays a graph corresponding to the recognized functional expression in a display part. The first display control unit displays a first user interface object for changing a numeric value set to a variable when a coefficient in the functional expression is the variable. The second display control unit displays a second user interface object for changing a numeric value as a constant when a coefficient in the functional expression is the constant. The coefficient changed display control unit displays a graph corresponding to the functional in which a numeric value changed by the first or second user interface object is set as a coefficient value,
