Solution Overview

Problem

Conventional charging devices for biological information measurement devices fail to ensure proper temperature correction and measurement due to heat generated during charging, which prevents accurate temperature-based measurements, such as blood glucose levels, until the device has cooled.

Innovation Solution

Incorporating a non-contact charging system with a controller and display that indicates the device is incapable of measurement for a specific time after charging, allowing it to cool naturally before use, thus enabling proper temperature correction and measurement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the battery is charged using a conventional contact-based charging device, then the battery can be recharged, but heat is generated inside the biological information measurement device which prevents proper temperature correction and measurement

Engineering Contradiction:

Improvecharging capabilityVSAvoidinternal temperature

Core Design Contradiction:

Duration of action of moving objectVSTemperature

Solution Approach 1:

The patent replaces the mechanical contact-based charging system with a wireless charging system using electromagnetic fields. The charging device includes a charging coil that generates a magnetic field to induce current in the measurement device's coil, eliminating direct physical contact and reducing heat transfer to the internal components.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a magnetic field as an intermediary medium for energy transfer between the charging device and the biological information measurement device. This intermediary allows power transmission without direct contact, preventing the heat generation issues associated with conventional charging methods.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the device is used immediately after charging, then convenience is improved, but measurement accuracy deteriorates due to insufficient temperature correction

Engineering Contradiction:

Improveusage convenienceVSAvoidmeasurement accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent implements a feedback mechanism where the controller monitors the internal temperature and charging status, then provides feedback to the display unit to show appropriate messages. The system automatically determines when the device is ready for use based on temperature conditions, balancing convenience with measurement accuracy.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent performs preliminary temperature monitoring and assessment during and after charging before allowing measurement operations. The controller evaluates temperature conditions in advance and only permits measurement when appropriate, ensuring accuracy while minimizing waiting time.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If a contact-based charging system is used, then the charging structure is simple, but the device complexity increases due to additional temperature management requirements

Engineering Contradiction:

Improvecharging structureVSAvoidheat generation

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical contact charging structure with a wireless electromagnetic charging system. This substitution eliminates the need for physical charging contacts and reduces the complexity of temperature management by preventing direct heat transfer pathways from the charging interface to internal components.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Certain implementations have a main body case having a contact face of a biological information measurement device on its surface, and a first non-contact charging portion composed of a charging coil disposed opposite the contact face with the biological information measurement device inside the main body case. In addition, some may have a controller that is connected to the first non-contact charging portion, and a display section that is connected to the controller. Upon completion of the charging of the biological information measurement device via the first non-contact charging portion, the controller connected to the display section may display on the display section that the biological information measurement device will be incapable of measurement for a specific length of time.
