Solution Overview

Problem

Current touch control unlocking methods on touch screen terminals, such as smartphones, are not user-friendly due to the requirement of dragging an unlock image along a specific path, which restricts flexibility and ease of use.

Innovation Solution

A method and device that allow touch control unlocking by defining unlock objects and locking zones on a touch-sensitive surface, enabling unlocking when the unlock object is moved outside the locking zone in any direction, providing a flexible and user-friendly operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional sliding gesture unlocking is used with confined positions and paths, then security control is maintained, but user-friendliness and operational flexibility deteriorate

Engineering Contradiction:
Improvesecurity controlVSAvoiduser-friendliness
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The unlocking zone is segmented into multiple candidate positions distributed across the screen, allowing users to choose from several valid unlocking locations rather than being confined to a single path. This segmentation maintains security by providing discrete valid positions while improving ease of operation by allowing flexible placement within the distributed candidate positions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from a one-dimensional sliding path constraint to a two-dimensional distributed position system. Multiple candidate positions are arranged across the screen surface in different dimensions, allowing users to drag the unlock image to any of these positions in various directions, thereby enhancing operational flexibility while maintaining security through controlled candidate position selection.

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

2Device complexity

If a fixed unlocking path is required, then system control is simplified, but operational flexibility and user-friendliness deteriorate

Engineering Contradiction:
Improvesystem controlVSAvoidoperational flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts the unlocking mechanism by providing multiple candidate positions instead of a fixed path. The unlock image can be dragged to any candidate position based on user preference and context, making the system adaptive to different user needs while maintaining manageable complexity through predefined position sets.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The unlocking system serves multiple functions by accommodating different user preferences and scenarios through multiple candidate positions. The same unlocking mechanism can adapt to various situations (one-handed operation, different screen orientations, accessibility needs) by allowing selection from distributed candidate positions, enhancing versatility without significantly increasing system complexity.

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

AI summary

For unlocking touch control of a touch control terminal, it is detected if any unlock object is selected, then the selected unlock object is tracked to see if the selected unlock object has slid to any of a plurality of unlocking positions outside the corresponding locking zone. If positive, the touch control for a function corresponding to the selected unlock object is unlocked.
