Solution Overview

Problem

Existing electronic devices face issues with accidental touch activation due to proximity sensor limitations, leading to unexpected power consumption and connectivity disruptions when in sleep mode, particularly in shallow or specially shaped pockets.

Innovation Solution

An anti-accidental touch management interface is provided, allowing users to enable or disable specific touch functions through a toggle system, with the processor determining and performing anti-accidental touch functions based on user settings and proximity detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the screen is made responsive to touch inputs in sleep mode to enable quick access to messages and calls, then user convenience is improved, but accidental touch activation occurs causing unnecessary power consumption and connectivity disruptions

Engineering Contradiction:

Improvequick access to messages and callsVSAvoidunnecessary power consumption

Core Design Contradiction:

Ease of operationVSLoss of energy

Solution Approach 1:

The system preemptively disables touch sensitivity in specific scenarios (sleep mode with pocket detection) before accidental touches can occur. By detecting pocket presence through proximity sensors or motion sensors beforehand, the system prevents accidental touch activation while maintaining quick access capability when genuinely needed.

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The system performs preliminary detection of pocket presence using proximity sensors or motion sensors before allowing touch inputs. This preliminary action enables the system to distinguish between intentional touches (when phone is out of pocket) and accidental touches (when phone is in pocket), thereby managing power consumption appropriately.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If proximity sensors are used to detect pocket presence for anti-accidental touch, then accidental touch prevention is improved, but the sensors cannot cover all pocket types particularly shallow or specially shaped pockets

Engineering Contradiction:

Improveaccidental touch preventionVSAvoidcoverage of different pocket types

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system combines multiple detection methods including proximity sensors, motion sensors, and touchscreen gesture recognition to detect pocket presence. This merged approach compensates for the limitations of individual sensors, enabling reliable detection across various pocket types including shallow or specially shaped pockets.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system implements a multi-functional detection mechanism that uses different sensor types and detection algorithms to universally cover various pocket scenarios. By making the detection system multi-functional, it can adapt to different pocket depths, shapes, and materials, thereby improving both reliability and adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Loss of energy

If touch functions are restricted in sleep mode to prevent accidental touches, then power consumption is reduced, but user access to quick settings and lock screen shortcuts is limited

Engineering Contradiction:

Improvepower consumption reductionVSAvoidaccess to quick settings and shortcuts

Core Design Contradiction:

Loss of energyVSEase of operation

Solution Approach 1:

The system dynamically adjusts touch sensitivity and responsiveness based on detected context (pocket presence, screen state, user interactions). When the phone is detected to be in a pocket, touch functions are restricted to save power. When taken out or when specific gestures are detected, full touch functionality is restored, providing flexible balance between power saving and user access.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system applies different touch sensitivity settings to different areas or modes of the interface. For example, certain areas of the lock screen may remain touch-responsive while others are disabled, or different gesture types may have different sensitivity thresholds. This local differentiation allows selective access to functions while maintaining overall power savings.

Inventive Principle:

Principle #3Local quality
