Solution Overview

Problem

Existing battery management systems fail to fully utilize the power level of batteries in electronic devices, leading to reduced endurance time due to inefficient power management during dormancy and wake-up states.

Innovation Solution

A battery management method that determines an operation mode based on the current power level of the battery, adjusting functions and power consumption to match the available power, and uses timers with adjustable delay and advance attributes to optimize wake-up times.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the electronic device is set in dormant state to prolong endurance time, then the battery endurance time is extended, but the battery power level is wasted and cannot be fully utilized

Engineering Contradiction:

Improvebattery endurance timeVSAvoidbattery power level waste

Core Design Contradiction:

Duration of action of moving objectVSLoss of energy

Solution Approach 1:

The patent implements dynamic operation modes that adjust the electronic device's power consumption characteristics based on real-time battery power levels. When the device wakes from dormant state, it dynamically selects between multiple operation modes (first operation mode with full functionality, second operation mode with restricted functionality) according to the current battery power level, thereby dynamically matching power consumption to available battery capacity and preventing energy waste.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of the electronic device by introducing operation modes that modify power consumption characteristics. The system monitors battery power level and adjusts operational parameters (functionality restrictions, performance levels) to match the available power, transforming the fixed dormant/wake-up binary state into a multi-level operational spectrum that optimizes energy utilization.

Inventive Principle:

Principle #35Parameter changes

2Loss of energy

If the electronic device wakes up frequently to check battery status, then the battery power level can be monitored and utilized effectively, but the power consumption increases and endurance time decreases

Engineering Contradiction:

Improvebattery power level utilizationVSAvoidpower consumption during wake-up

Core Design Contradiction:

Loss of energyVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic wake-up mechanisms where the electronic device wakes from dormant state at predetermined intervals to check battery power levels and determine appropriate operation modes. This periodic action balances the need to monitor battery status with the need to minimize wake-up frequency and associated power consumption, optimizing the trade-off between energy utilization and energy expenditure.

Inventive Principle:

Principle #19Periodic action
