Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple measurement devices into a single integrated wearable data processing system that includes sensors, Bluetooth module, NFC module, and cloud platform. This merging approach maintains high data fidelity while simplifying data retrieval through unified communication protocols and centralized processing.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces an intermediary cloud platform that mediates between multiple measurement devices and the data retrieval process. The cloud platform receives data from various sensors, processes and stores it, and provides unified access points for data retrieval, thereby reducing the complexity of direct data retrieval from multiple devices.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Speed

If wireless data connections are used for data retrieval, then data transfer speed is improved, but reliability deteriorates in DIL environments

Engineering Contradiction:

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent implements dynamic communication switching between Bluetooth and NFC protocols based on environmental conditions. The system can transition between different communication modes to maintain reliable data transfer in DIL environments where one protocol may be more reliable than the other.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes communication parameters by switching between different wireless protocols (Bluetooth and NFC) with different transmission characteristics. This allows the system to adapt to varying environmental conditions and maintain reliable data transfer despite changes in connectivity reliability.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If continuous wireless connectivity is maintained for data transmission, then data retrieval efficiency is improved, but adaptability to DIL environments deteriorates

Engineering Contradiction:

Improvedata retrieval efficiencyVSAvoidadaptability to disconnected environments

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent implements preliminary data caching and local processing capabilities within the wearable device. Data is collected, processed, and stored locally before transmission, allowing the system to maintain productivity during disconnected periods and adapt to DIL environments by operating autonomously until connectivity is restored.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent employs periodic data synchronization instead of continuous transmission. The system periodically checks for connectivity and transmits data in batches, which maintains data retrieval efficiency while improving adaptability to disconnected environments by minimizing continuous dependency on wireless connectivity.

Inventive Principle:

Principle #19Periodic action

4Productivity

If high data transfer speeds are used for data retrieval, then data collection efficiency is improved, but loss of information increases during transmission

Engineering Contradiction:

Solution Approach 1:

The patent implements feedback mechanisms where the system verifies data transmission integrity and can request retransmission if errors are detected. This feedback loop maintains high data collection efficiency while preventing information loss through corrective actions when transmission errors occur.

Inventive Principle:

Principle #23Feedback
