Solution Overview

Problem

Mobile telephones experience increased power consumption and radiation exposure due to their expanded functionalities and poor signal strength areas, leading to frequent recharging and elevated radiation emission, particularly when indoors or in vehicles.

Innovation Solution

Implementing a reduced power sequence in mobile telephones that alternates between low and normal transmission power levels based on signal strength and location, such as being in a vehicle, to conserve battery life and reduce radiation exposure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mobile telephone continuously transmits at normal power level to maintain communication, then communication reliability is improved, but power consumption increases

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies periodic action by implementing a reduced power sequence that alternates between normal transmission power and reduced transmission power at predetermined intervals. The mobile telephone transitions from normal operation to reduced power mode after detecting poor signal conditions, maintaining communication functionality while significantly reducing power consumption during extended periods at reduced power levels.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent applies dynamics by making the transmission power level adaptive rather than static. The system dynamically adjusts transmission power based on detected signal conditions, transitioning between normal and reduced power states according to signal strength measurements and predetermined thresholds, thereby optimizing the balance between communication reliability and power consumption.

Inventive Principle:

Principle #15Dynamics

2Reliability

If mobile telephone increases transmission power to maintain signal quality in poor signal areas, then signal quality is improved, but radiation exposure increases

Engineering Contradiction:

Improvesignal qualityVSAvoidradiation exposure

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent reduces radiation exposure by implementing periodic transitions to reduced power mode. During poor signal conditions, the system alternates between normal and reduced transmission power levels, maintaining necessary communication signal quality while minimizing the duration and intensity of high-power transmissions that generate harmful radiation.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent applies parameter changes by modifying the transmission power level parameter from its normal value to a reduced value during poor signal conditions. This parameter adjustment allows the system to maintain communication functionality while reducing the harmful radiation exposure associated with continuous high-power transmission.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If mobile telephone performs multiple additional functions, then functionality is improved, but power consumption increases

Engineering Contradiction:

ImprovefunctionalityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent addresses the power consumption issue by implementing periodic reduced power sequences that allow the mobile telephone to perform multiple functions while reducing overall power usage. The system alternates between normal and reduced power modes, enabling functionality maintenance during normal periods while conserving battery life during extended reduced power periods.

Inventive Principle:

Principle #19Periodic action

4Duration of action of moving object

If mobile telephone operates in reduced power mode for extended periods, then battery life is extended, but communication reliability may deteriorate

Engineering Contradiction:

Improvebattery lifeVSAvoidcommunication reliability

Core Design Contradiction:

Duration of action of moving objectVSReliability

Solution Approach 1:

The patent resolves this contradiction by implementing periodic transitions between normal and reduced power modes rather than sustained reduced power operation. The system monitors signal conditions and transitions to normal power mode when signal quality improves or communication reliability requirements increase, thereby maintaining adequate communication reliability while extending battery life through extended periods at reduced power levels.

Inventive Principle:

Principle #19Periodic action
