Solution Overview

Problem

Conventional body information obtaining devices face challenges in securely transmitting and managing biometric data across multiple electronic devices, often resulting in personal information leakage or incorrect data transmission due to pairing issues and lack of differentiation between user and non-user information.

Innovation Solution

An electronic device equipped with a communication circuit, memory for storing identifiers of external devices, and a processor that receives biometric information, selects the appropriate device based on received data, and transmits it securely, using a server to determine the correct device and manage data transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a body information obtaining device pairs with a single electronic device using Bluetooth or serial communication, then data transmission is established, but the user cannot differentiate their information from others' information and personal information leakage occurs

Engineering Contradiction:

Improvedata transmission accuracyVSAvoidpersonal information leakage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system pre-stores user information (identifiers, biometric data, device information) in a database before actual data transmission occurs. When a body information obtaining device connects, the server proactively compares the device's transmitted information with pre-stored user profiles to identify the correct user, preventing information leakage by ensuring data is sent only to the authenticated user's device.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The server implements a feedback mechanism where the body information obtaining device transmits its information to the server, which then compares this information against pre-stored user profiles and returns the identified user's device information. This closed-loop feedback ensures accurate device identification and prevents wrong data transmission.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If Wi-Fi enables peer-to-multiple data communication among several user terminals, then one-to-multiple data transmission is achieved, but the device still fails to differentiate user information and exposes personal information

Engineering Contradiction:

Improvemulti-device communication capabilityVSAvoidpersonal information exposure

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The server acts as an intermediary between the body information obtaining device and multiple user terminals. Instead of direct peer-to-peer communication that exposes user information, all communication passes through the server which mediates the interaction by comparing device information with pre-stored user profiles and routing data only to the authenticated user's device.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

User information is pre-stored in the server's database before any communication occurs. This preliminary preparation enables the server to quickly and accurately identify users during communication sessions, ensuring that even in multi-device Wi-Fi environments, personal information remains protected by proactive user identification.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If conventional devices require plugging into connection ports for data transmission, then direct connection is established, but the user must manually connect devices and pairing issues occur

Engineering Contradiction:

Improveconnection stabilityVSAvoiddevice connection convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces mechanical connection methods (physical plugging into ports) with wireless communication technologies (Bluetooth, Wi-Fi). This substitution eliminates the need for manual physical connection while maintaining reliable data transmission through server-mediated identification and routing of information.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
