Solution Overview

Problem

Conventional electronic devices with touch screens require complex key manipulations for transforming mathematical formulas and graphics, limiting user intuitiveness and operability.

Innovation Solution

An electronic device with a display that detects contact positions, correlates touch manipulation modes with operational processing, allowing users to intuitively transform mathematical formulas and graphics through touch inputs, using a processor to read and perform corresponding processing from stored data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional key manipulation methods are used for transforming mathematical formulas and graphics, then operational functionality is achieved, but user operability and intuitiveness deteriorate due to complex manipulation requirements

Engineering Contradiction:
Improveuser operabilityVSAvoidmanipulation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical key input system with a touch panel interface that detects contact positions directly on the display. This substitution eliminates the need for separate physical keys and complex manipulation sequences, allowing users to transform mathematical formulas and graphics through intuitive touch gestures performed directly on the displayed content.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The touch panel enables users to perform transformations by directly interacting with the displayed mathematical formulas and graphics through touch gestures. The system responds automatically to touch inputs without requiring users to navigate through menus or learn complex key sequences, making the device serve itself through direct user interaction with the visual content.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If touch panel is used only as a continuation of conventional input method for selecting menu items, then device complexity is maintained, but ease of operation does not improve significantly

Engineering Contradiction:
ImproveintuitivenessVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements dynamic touch manipulation modes that adapt to the user's input gestures. The system detects different contact positions and gestures on the touch panel, dynamically determining the appropriate transformation operation to perform. This dynamic response allows the same touch interface to handle multiple transformation types without requiring complex predefined menus or modes.

Inventive Principle:
Principle #15Dynamics
