Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing screenshot methods on mobile terminals are complex and inaccurate, requiring users to manually adjust cropping areas using positioners, which can lead to capturing non-target content due to the presence of multiple display elements.

Innovation Solution

A method where the terminal enters a screenshot state with a corresponding relationship between display controls and elements, allowing users to select a target area by long pressing on a display control, eliminating the need for manual adjustments and improving accuracy through automatic determination of the cropping area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual adjustment using positioners is used for screenshot cropping, then the screenshot function can be implemented, but the operation becomes complex and inaccurate leading to capturing non-target content

Engineering Contradiction:

Improvecropping area accuracyVSAvoidscreenshot operation complexity

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system automatically determines the cropping area based on the localization operation position without requiring manual adjustment by the user. The terminal itself performs the task of area determination, eliminating the need for users to manually drag positioners and adjust boundaries, thus resolving the contradiction between operational simplicity and positioning accuracy.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical manual adjustment system (dragging positioners with fingers) with an automated computational system that calculates the cropping area based on touch coordinates and display control relationships. This substitution eliminates the complexity of manual mechanical adjustment while maintaining or improving accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If multiple display elements are present on the screen, then the display interface is rich and functional, but it becomes difficult to accurately capture only the target content

Engineering Contradiction:

Improvedisplay interface functionalityVSAvoidtarget area selection accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system establishes a corresponding relationship between display controls and their positions, and uses the localization operation feedback (touch position) to automatically determine the cropping area. This feedback mechanism allows the system to understand which display element the user intends to capture and automatically adjusts the cropping boundaries accordingly, resolving the difficulty of selecting target content among multiple display elements.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent divides the display interface into distinct regions corresponding to different display controls, and establishes a mapping between these segments and their control elements. This segmentation allows the system to identify and capture only the relevant target area based on the user's localization operation, even when multiple display elements are present.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If manual positioning and adjustment is required, then flexibility in selecting any area is achieved, but the operation time increases and efficiency decreases

Engineering Contradiction:

Improvecropping area selection flexibilityVSAvoidscreenshot operation efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The system pre-establishes the corresponding relationship between display controls and their positions before the screenshot operation. When the user performs a localization operation, the cropping area is immediately determined based on this pre-established mapping, eliminating the need for real-time manual adjustment and significantly improving operation efficiency while maintaining flexibility.
