Solution Overview

Problem

Current electronic devices require unnecessary screen transitions and depth movements for handwriting input, making it inconvenient for users to input notes while viewing images, as they need to switch between different application screens and input windows.

Innovation Solution

An electronic device with a touch screen display and a force sensor that detects pressure inputs, allowing for continuous handwriting input without unnecessary screen transitions by processing touch and pressure data to provide a seamless user interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the electronic device provides a keypad or handwriting input window for data input, then data input capability is improved, but screen transitions and window switching are required which increases operation complexity

Engineering Contradiction:

Improvedata input convenienceVSAvoidscreen transition requirements

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the image viewing function and handwriting input function into a single integrated interface. The handwriting input window is overlaid directly on the image display area, allowing users to view images and input notes simultaneously without switching screens or applications. This combination eliminates the need for multi-screen transitions while maintaining both functionalities.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The touch screen display serves multiple functions simultaneously: it displays images, detects touch inputs, measures pressure inputs through the force sensor, and provides handwriting recognition. This multi-functionality allows the single interface to handle both viewing and input tasks without requiring separate dedicated screens or windows.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the electronic device switches between image application screen and notes application screen for note input, then note creation functionality is achieved, but multi-screen switching increases time consumption

Engineering Contradiction:

Improvenote creation capabilityVSAvoidscreen switching time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system prepares the handwriting input window in advance within the same screen interface, so when users want to input notes, the input area is already available and visible. This eliminates the need to switch to a separate notes application first, allowing immediate note input without time-consuming screen transitions.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If the electronic device requires switching between keypad input window and handwriting input window, then different input methods are provided, but input continuity is interrupted by window switching

Engineering Contradiction:

Improveinput method varietyVSAvoidinput continuity

Core Design Contradiction:

Adaptability or versatilityVSDuration of action of moving object

Solution Approach 1:

Both keypad input and handwriting input capabilities are merged into the same overlay interface structure. Users can switch between input methods without leaving the current screen or triggering window transitions, maintaining continuous input flow. The system detects the input type (keypad or handwriting) and processes it appropriately within the unified interface.

Inventive Principle:

Principle #5Merging (Combining)
