Solution Overview

Problem

Mobile terminals face increased battery consumption due to enhanced performance, necessitating improved power management to extend usage time without compromising functionality.

Innovation Solution

A mobile terminal system that controls power consumption by designating contact addresses for battery management, implementing a limited mode based on battery levels, and selectively limiting functions to conserve power, while notifying designated contacts of the power status and allowing remote control operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If terminal performance is enhanced to provide multifunctionality, then device functionality is improved, but battery consumption increases

Engineering Contradiction:
Improvedevice functionalityVSAvoidbattery consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic power management by adjusting terminal functions based on real-time battery status. When battery level drops below a threshold, the system automatically limits non-essential functions while maintaining critical operations, creating a dynamic adaptation between performance and power consumption rather than a static trade-off

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments functions into priority levels, allowing critical functions to continue operating while non-critical functions are limited or suspended during low-power states. This segmentation enables selective power management where different function groups are independently controlled based on battery availability

Inventive Principle:
Principle #1Segmentation

2Duration of action of moving object

If battery power preservation mode is implemented to reduce power consumption, then battery life is extended, but device functionality is reduced

Engineering Contradiction:
Improvebattery lifeVSAvoiddevice functionality
Core Design Contradiction:
Duration of action of moving objectVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts functionality based on battery status, transitioning between full-performance mode and power-saving mode. This dynamic approach allows the device to maintain optimal functionality when power is abundant while automatically conserving energy when battery levels drop, resolving the contradiction between battery life and functionality

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies different power management strategies to different function groups based on their priority and power consumption characteristics. Critical functions receive preferential power allocation while non-critical functions are scaled back, creating localized quality differences in power distribution across the system

Inventive Principle:
Principle #3Local quality

3Ease of operation

If notification functions are activated to inform contacts of power status, then user convenience is improved, but additional power consumption occurs

Engineering Contradiction:
Improveuser convenienceVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The notification function is implemented partially - it activates only under specific conditions (when battery level drops below threshold and the device is in power-saving mode) rather than continuously. This conditional activation provides user convenience when needed while minimizing unnecessary power consumption during normal operation

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system automatically monitors battery status and triggers notifications without requiring user intervention. The notification mechanism serves itself by detecting power thresholds and autonomously contacting designated recipients, reducing the operational burden on users while managing power consumption efficiently

Inventive Principle:
Principle #25Self-service
