Solution Overview

Problem

Existing technologies do not effectively address power consumption reduction in wireless communication between measurement devices and information terminals, particularly in systems where connection opportunities are restricted by timing control, leading to inefficient power usage.

Innovation Solution

A measurement device and information terminal system that transmits an advertise signal before measuring biological information, connects to a requested terminal, and switches connections if the user changes, adjusting signal transmission intervals based on user identity, thereby reducing power consumption and maintaining convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the transmission timing for advertising is limited to reduce power consumption, then power consumption is reduced, but the opportunity for connection is likewise restricted

Engineering Contradiction:

Improvepower consumptionVSAvoidconnection opportunity

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the advertising transmission interval adjustable based on operational state. The control unit dynamically changes the advertising transmission interval from a first interval (when not measuring) to a second interval (when measuring), allowing the system to adapt transmission frequency to actual needs and resolve the contradiction between power saving and connection availability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of advertising transmission interval based on measurement state. By setting different transmission intervals (first interval when not measuring, second interval when measuring), the system optimizes power consumption while ensuring connections are available when measurement activities occur, thus resolving the technical contradiction.

Inventive Principle:

Principle #35Parameter changes

2Use of energy by moving object

If the advertising signal transmission interval is extended to reduce power consumption, then power consumption is reduced, but the connection responsiveness deteriorates

Engineering Contradiction:

Improvepower consumptionVSAvoidconnection responsiveness

Core Design Contradiction:

Use of energy by moving objectVSSpeed

Solution Approach 1:

The system dynamically adjusts the advertising transmission interval based on whether measurement is currently being performed. When measurement is active, the interval is shortened to ensure responsive connections; when measurement is inactive, the interval is extended to save power. This dynamic adjustment resolves the contradiction between power consumption and connection responsiveness.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements periodic advertising signal transmission with variable periods. By using different transmission intervals (first interval and second interval) depending on measurement state, the system creates an optimized periodic action pattern that reduces overall power consumption while maintaining responsiveness when needed.

Inventive Principle:

Principle #19Periodic action

3Ease of operation

If the connection is maintained continuously to improve data transfer convenience, then data transfer convenience is improved, but power consumption increases

Engineering Contradiction:

Improvedata transfer convenienceVSAvoidpower consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent uses periodic advertising signal transmission instead of continuous connection maintenance. The control unit transmits advertising signals at predetermined intervals, allowing the information terminal to periodically establish connections for data transfer. This periodic approach maintains data transfer convenience while significantly reducing power consumption compared to continuous connection.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The control unit transmits advertising signals in advance at predetermined intervals, allowing the information terminal to be notified before measurement data is ready. This preliminary action enables timely connection establishment for data transfer, maintaining convenience while avoiding continuous connection and reducing power consumption.

Inventive Principle:

Principle #10Preliminary action

AI summary

A measurement device, an information terminal, a control method and a control program that can reduce power consumption. A measurement device that can measure biological information. The measurement device includes a wireless communication unit and a controller. The wireless communication unit is configured to transmit the measurement data of the biological information to an information terminal. Before an instruction to measure the biological information, the controller performs control to wirelessly transmit an advertise signal and wirelessly connect to the information terminal that made a connection request in response to the advertise signal, and at a time of measuring the biological information, in a case where a subject is different from a user a of the information terminal, the controller controls the wireless communication unit to disconnect from the information terminal and wirelessly connect to the information terminal of the subject.
