Solution Overview

Problem

Mobile terminals face challenges with low battery autonomy and high energy consumption due to increasing component demands, particularly for radio network detection, which requires user intervention and consumes battery life quickly.

Innovation Solution

A mobile terminal with automatic power supply means controlled by movement detection, using either a vibration detector powered by the battery or an autonomous vibration generator that detects and supplies power, allowing components like the radio interface to activate only when in a radio coverage area and deactivate when not in use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the terminal is kept in active mode to enable automatic radio network detection, then the service availability is improved, but the energy consumption increases and battery autonomy decreases

Engineering Contradiction:

Improveservice availabilityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The terminal dynamically adjusts its operational state based on motion detection. When motion is detected, the terminal transitions from standby to active mode, enabling radio network detection and service availability. When no motion is detected, the terminal returns to standby mode to conserve energy. This dynamic state transition resolves the contradiction by making the system adaptive to actual usage conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The terminal uses its own motion detection capabilities to automatically trigger power supply to the radio interface. The system self-activates when motion is detected without requiring user intervention, and self-deactivates when motion ceases. This self-service mechanism ensures service availability when needed while minimizing energy consumption during idle periods.

Inventive Principle:

Principle #25Self-service

2Use of energy by moving object

If the terminal switches to standby mode to save energy, then the energy consumption is reduced, but the activation requires user intervention which reduces ease of operation

Engineering Contradiction:

Improveenergy consumptionVSAvoiduser intervention requirement

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The terminal automatically activates from standby mode by detecting its own motion. The motion detection means trigger the power supply to the radio interface without requiring any user action. This self-service approach eliminates the need for user intervention while maintaining energy-saving standby operation during idle periods.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The terminal performs preliminary motion detection while in standby mode. When motion is detected, the system proactively activates the radio interface before any service request is made. This preliminary action ensures the terminal is ready for immediate service while automatically managing the transition from standby to active state.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If the radio interface is constantly active to detect radio networks automatically, then the service availability is improved, but the battery autonomy decreases due to high energy consumption

Engineering Contradiction:

Improveautomatic detection capabilityVSAvoidbattery autonomy

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The radio interface operates dynamically - active when motion is detected and standby when motion is absent. This dynamic operation provides automatic radio network detection capability when the terminal is in use, while extending battery autonomy during periods when the terminal is stationary or not being used.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The terminal periodically checks for motion and adjusts its operational state accordingly. Rather than continuous operation, the system uses periodic motion detection to trigger radio interface activation only when necessary, reducing overall energy consumption while maintaining automatic detection capability during active periods.

Inventive Principle:

Principle #19Periodic action
