Solution Overview

Problem

Graphic display devices cannot easily change the length or size of designated graphic elements with simple user operations, limiting user flexibility in modifying displayed graphics.

Innovation Solution

A graphic drawing device with a display unit and processor that includes a slider interface for users to adjust measurement values of graphic elements, allowing for easy modification and display of changed graphics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a graphic display device designates a side or corner of a graphic to measure length or size, then the measurement value can be displayed, but the device cannot easily change the length or size of the designated part with simple user operations

Engineering Contradiction:

Improveease of changing graphic dimensionsVSAvoidcomplexity of graphic modification operation

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces a slider as an intermediary control element between the user and the graphic modification process. The slider acts as a mediator that translates simple user input (dragging the slider) into precise changes of measurement values, thereby enabling easy modification of graphic dimensions without complex operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical or manual methods of graphic modification (such as directly manipulating graphic elements or entering values) with a graphical user interface element (slider). This substitution allows users to change measurement values through intuitive drag operations rather than complex mechanical adjustments or manual input.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If a slider interface is added to allow easy adjustment of measurement values, then user flexibility in modifying graphics is enhanced, but the interface complexity increases

Engineering Contradiction:

Improveflexibility in graphic manipulationVSAvoidcomplexity of user interface

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The slider interface is designed to be universal and multi-functional. It can be applied to various measurement items (length, size, etc.) of different graphic elements, providing a single versatile control mechanism that handles multiple adjustment tasks rather than requiring separate controls for each parameter.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The slider enables easy changes of measurement parameters by translating the user's dragging action into numerical value adjustments. The system monitors the slider position and dynamically updates the measurement values, allowing flexible parameter modification through a simple visual interface rather than complex programming or manual calculation.

Inventive Principle:

Principle #35Parameter changes

AI summary

A graphic drawing device includes a display unit and a processor. The processor executes a process includes: displaying on the display unit, a measurement item corresponding to at least one graphic part drawn on the display unit; displaying on the display unit, a slider identifier for setting a slider in a case that the displayed measurement item is a type capable of setting a slider for changing a value of the displayed measurement item; and displaying on the display unit, a slider for changing the value of the displayed measurement item according to an operation by a user with respect to the displayed slider identifier.
