Solution Overview

Problem

Conventional electronic devices capable of recording life logs face challenges in improving user convenience while minimizing power consumption, as the processing required for acquiring life log data increases power consumption and activating sensors can be inefficient.

Innovation Solution

An electronic device with a situation detecting unit, an acquiring unit, a situation determining unit, and a device setting unit that automatically adjusts its functions based on detected user situations and stored life log information, activating only necessary sensors and features for specific activities to conserve power.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If life log processing is performed continuously to improve user convenience, then user convenience is improved, but power consumption increases

Engineering Contradiction:

Improveuser convenienceVSAvoidpower consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary analysis of life log information to identify behavior patterns in advance, then uses these pre-established patterns to automatically set device functions when similar situations are detected, avoiding continuous processing and reducing power consumption while maintaining user convenience

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The device automatically adjusts its own functions based on detected behavior patterns from life log data, eliminating the need for manual user adjustments and enabling the system to serve itself by making intelligent decisions about function activation based on situational context

Inventive Principle:

Principle #25Self-service

2Measurement precision

If sensors are activated continuously to detect user situations accurately, then detection accuracy is improved, but power consumption increases

Engineering Contradiction:

Improvesituation detection accuracyVSAvoidpower consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

Instead of continuous sensor activation, the system periodically processes life log information and activates sensors only when behavior patterns indicate a need for situation detection, maintaining detection accuracy while significantly reducing power consumption through intermittent operation

Inventive Principle:

Principle #19Periodic action

3Adaptability or versatility

If device functions are activated for all possible activities to ensure versatility, then adaptability is improved, but power consumption increases

Engineering Contradiction:

Improvedevice function coverageVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system activates specific device functions locally and selectively based on the detected behavior pattern and situational context, rather than maintaining all functions active, thereby providing appropriate adaptability for each situation while minimizing overall power consumption

Inventive Principle:

Principle #3Local quality
