Solution Overview

Problem

Existing wearable devices with sensors at different positions face challenges in efficiently managing power consumption due to frequent communication between sensors, which is not adequately addressed in current technologies.

Innovation Solution

An information processing apparatus that includes a first sensor detecting a trigger signal and requesting second detection information from a second sensor at a different position, with a local communication unit receiving this information and a processing determination unit determining processing based on both sets of data, thereby reducing communication frequency and power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If sensors at different positions continuously transmit and receive detection data, then detection accuracy and responsiveness are improved, but power consumption increases

Engineering Contradiction:

Improvedetection accuracyVSAvoidpower consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The first sensor performs preliminary detection continuously and only triggers communication with the second sensor when a predetermined trigger signal is detected, meaning detection and communication actions are prepared and executed only when necessary

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of continuous periodic communication between sensors, the system uses event-driven periodic action where communication occurs only when trigger signals are detected, reducing overall communication frequency while maintaining detection accuracy

Inventive Principle:

Principle #19Periodic action

2Reliability

If communication frequency between sensors is increased, then data synchronization and detection reliability are improved, but power consumption increases

Engineering Contradiction:

Improvedetection reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary detection with the first sensor and only initiates communication with the second sensor when trigger signals are detected, ensuring reliable data collection while minimizing unnecessary communication

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The first sensor autonomously determines when trigger signals are detected and independently initiates requests for second detection information, reducing the need for continuous coordinated communication between sensors

Inventive Principle:

Principle #25Self-service

AI summary

Provided is an information processing apparatus including an information request unit, in a case in which a predetermined trigger signal is detected in a first sensor, requesting second detection information based on a signal detected in a second sensor located at a different position from that of the first sensor, a local communication unit receiving the second detection information, and a processing determination unit determining processing to be executed based on first detection information based on a signal detected in the first sensor and the second detection information. Power consumption can be further suppressed in an information processing apparatus in which sensors are provided at different positions.
