Innovation Solution

A sample measuring device equipped with a sensor strip detector, measurement data storage, display unit, and a first data transmitter/receiver for wireless communication, which performs initial authentication and automatically establishes connections with nearby devices using the Bluetooth standard, allowing for automatic pairing and data transmission without user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cable connection is used to transfer measurement data to PC, then data transfer is reliable, but operation becomes cumbersome and time-consuming

Engineering Contradiction:
Improvedata transfer reliabilityVSAvoidconnection operation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical cable connection system with a wireless communication system. The sample measuring device includes a wireless communication unit that transmits measurement data to the personal computer wirelessly, eliminating the need for physical cable connections while maintaining data transfer reliability through protocol-based communication.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a wireless communication protocol as an intermediary between the sample measuring device and the personal computer. This intermediary enables data transfer without direct physical contact, resolving the contradiction between reliable data transfer and ease of operation by providing a standardized wireless interface.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If cable connection is required for data transfer, then data can be stored in PC, but user burden increases due to repeated connection operations

Engineering Contradiction:
Improvedata storage capabilityVSAvoidconnection setup time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements preliminary pairing and authentication between the sample measuring device and the personal computer. Once paired, the devices maintain a established wireless connection profile, allowing subsequent data transfers to occur automatically without requiring users to re-establish connections each time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The wireless communication unit automatically manages data transfer operations, including connection establishment, authentication, and data transmission. This self-service capability eliminates the need for manual connection setup by the user, reducing time loss while ensuring data is properly stored in the PC.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If wireless communication is implemented, then ease of operation improves, but device complexity increases

Engineering Contradiction:
Improveconnection operation easeVSAvoidcommunication system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The wireless communication unit is designed to perform multiple functions including data transmission, authentication, and connection management within a single integrated component. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while achieving improved ease of operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Productivity

If automatic authentication is performed, then productivity increases, but device complexity increases

Engineering Contradiction:
Improvedata transfer efficiencyVSAvoidauthentication system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The authentication functionality is merged with the wireless communication unit rather than being implemented as a separate system. The authentication process is integrated into the connection establishment protocol, allowing automatic verification of the personal computer's identity during the initial pairing phase without requiring additional dedicated authentication hardware or software components.

Inventive Principle:
Principle #5Merging (Combining)
