Solution Overview

Problem

Low-end and low-cost mobile phones without a motion sensor cannot enter doze mode, leading to increased standby power consumption, which compromises product competitiveness and battery life due to the requirement of an additional hardware device for motion detection.

Innovation Solution

A control method that determines if a virtual motion sensor is present in the mobile terminal, enters doze mode when a predetermined time threshold is met without motion sensor hardware, and exits when the device is powered on or connected to a power source.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If a motion sensor is added to enable doze mode, then standby power consumption is reduced, but device cost increases

Engineering Contradiction:
Improvestandby power consumptionVSAvoiddevice cost
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent creates a virtual motion sensor that replicates the functionality of a physical motion sensor through software simulation. The virtual sensor generates motion detection events based on system state changes (screen on/off, charging states) without requiring actual hardware, thereby enabling doze mode functionality in cost-sensitive devices while avoiding the expense of physical motion sensor components

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical/physical motion sensor hardware with a software-based virtual motion sensor implementation. By substituting the physical detection mechanism with logical state monitoring and simulation, the system achieves motion sensor functionality without the associated hardware costs, directly resolving the contradiction between energy efficiency and device cost

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

2Duration of action of moving object

If a motion sensor is added to support doze mode, then battery life is extended, but product competitiveness is weakened

Engineering Contradiction:
Improvebattery lifeVSAvoidproduct competitiveness
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The virtual motion sensor copies the essential functionality of a physical motion sensor enough to trigger doze mode transitions, maintaining battery life benefits while avoiding the hardware addition that would harm product competitiveness in cost-sensitive market segments

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent changes the fundamental parameter of motion detection from physical hardware-based detection to software-state-based detection. This parameter change allows the system to achieve the same functional outcome (enabling doze mode for extended battery life) without the hardware overhead that would reduce product competitiveness

Inventive Principle:
Principle #35Parameter changes

AI summary

A control method for a doze mode of a mobile terminal includes: determining whether the mobile terminal conforms with a mode switch condition; detecting whether a virtual motion sensor is disposed in the mobile terminal when the mobile terminal conforms with the mode switch condition; determining whether a duration for which the mobile terminal conforms with the mode switch condition exceeds a predetermined time threshold value, when the virtual motion sensor is disposed in the mobile terminal; and entering the doze mode when the duration for which the mobile terminal conforms with the mode switch condition exceeds the predetermined time threshold value. A computer readable storage medium and a mobile terminal are also provided.
