Solution Overview

Problem

Current charging modes for terminals lead to rapid energy loss, shortened battery life, and potential safety hazards due to inefficient charging circuit management, especially when the terminal is in a high-power consumption state or remains in a charging state for an extended period.

Innovation Solution

A control method and apparatus that dynamically switch the charging circuit on or off based on the terminal's operational state, using state markers or function-interrupt requests to determine whether the terminal is in an operation or standby state, ensuring continuous charging during active use and conserving energy and preventing overheating during idle periods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the terminal is kept in charging state after full charge, then the battery can be continuously charged during high-power consumption services, but the terminal body heats up and energy is wasted

Engineering Contradiction:
Improvecharging durationVSAvoidterminal body temperature
Core Design Contradiction:
Duration of action of moving objectVSTemperature

Solution Approach 1:

The charging circuit's working state is dynamically adjusted based on terminal operational status. The system transitions between charging and non-charging states according to real-time detection of operational markers, optimizing both charging duration and temperature control

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system continuously monitors the terminal's operational state through markers from functional modules and uses this feedback to control the charging circuit. When no operational markers are detected, the charging circuit is switched off; when markers appear, charging is activated or maintained

Inventive Principle:
Principle #23Feedback

2Loss of energy

If the charging circuit is switched off after full charge, then energy waste and heating are prevented, but the terminal cannot be continuously charged during high-power consumption services

Engineering Contradiction:
Improveenergy wasteVSAvoidcharging availability
Core Design Contradiction:
Loss of energyVSDuration of action of moving object

Solution Approach 1:

The charging circuit operates in a dynamic manner, switching between on and off states based on terminal needs. This resolves the contradiction by enabling charging only when necessary (during operational states) while avoiding continuous charging during idle periods

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Real-time monitoring of operational markers provides feedback that triggers appropriate charging actions. The system detects when services are running and activates charging accordingly, ensuring energy is supplied only when the terminal actually needs it

Inventive Principle:
Principle #23Feedback

3Reliability

If trickle charge is applied after full charge, then the battery can be recharged when voltage drops, but the charging circuit remains on causing heat and energy waste

Engineering Contradiction:
Improvebattery charging reliabilityVSAvoidenergy waste
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The system replaces static trickle charging with dynamic state-based charging control. Charging is activated or maintained only when operational markers indicate the terminal is in use, and switched off when idle, regardless of battery voltage levels

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses feedback from operational markers rather than solely relying on battery voltage thresholds. This ensures charging occurs based on actual terminal needs rather than just battery state, preventing unnecessary energy consumption

Inventive Principle:
Principle #23Feedback

AI summary

The present disclosure provides a control method for charging a terminal and an apparatus thereof. The method includes steps of: judging whether the terminal is in an operation state or a standby state when the terminal is in a full-charged state (101); controlling a charging circuit of the terminal to be in a switching-on state when the terminal is in the operation state (102); and controlling the charging circuit of the terminal to be in a switching-off state when the terminal is in the standby state. With the control of switching-on or switching-off of the charging circuit based on the states of the terminal, the service life of the terminal is prolonged, a heat emission phenomenon caused by long-time charging of the terminal is avoided, and the charging safety of the terminal is ensured.
