Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical settings, especially in 'disconnection, intermittent, or low-bandwidth' environments, there is a challenge in accessing, processing, and exchanging healthcare data due to limitations in data transmission, storage, and processing capabilities, which is critical in urgent medical situations such as battlefields, remote operations, or natural disasters.
Innovation Solution
A computer-implemented method using near-field communications (NFC) and Bluetooth components to encode and decode healthcare data, allowing for efficient data transmission and storage through NFC initiation signals, data compression, and QR code generation and decoding, enabling data exchange even in limited bandwidth conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If healthcare data is transmitted using traditional wireless communication methods in DIL environments, then data transmission can occur, but transmission reliability and speed are severely limited
Solution Approach 1:
The patent segments the data transmission process into two distinct phases: NFC initiation for establishing secure connection and Bluetooth low-energy transmission for actual data transfer. This segmentation allows each protocol to operate optimally - NFC provides reliable pairing while Bluetooth handles efficient data transfer, resolving the contradiction between speed and reliability in DIL environments.
Solution Approach 2:
The patent uses NFC as an intermediary mechanism to establish secure communication channels between devices before Bluetooth data transmission occurs. This intermediary approach ensures reliable device pairing and authentication, which then enables efficient Bluetooth data transfer, simultaneously improving both transmission reliability and speed.
2Loss of information
If healthcare data is stored locally in wearable devices, then data accessibility improves, but data capacity and processing capabilities are limited
Solution Approach 1:
The patent implements multi-functionality by enabling the wearable device to operate in multiple modes: local data processing mode for immediate accessibility, cloud synchronization mode for unlimited storage capacity, and hybrid mode combining both. This allows the system to adapt between data accessibility and storage capacity requirements based on environmental conditions and user needs.
Solution Approach 2:
The patent dynamically adjusts data handling strategies based on real-time conditions - when connectivity is available, data is synchronized to cloud for expanded capacity; when disconnected, data is processed locally for immediate accessibility. This dynamic adaptation resolves the contradiction between storage capacity and accessibility by allowing both to be achieved at different times as needed.
3Productivity
If data compression algorithms are applied to healthcare data, then data transmission efficiency improves, but processing complexity increases
Solution Approach 1:
The patent implements self-service by having the wearable device automatically detect data types, select appropriate compression algorithms, and execute compression without user intervention. The system monitors its own processing capabilities and environmental conditions to autonomously optimize data transmission efficiency while managing processing complexity through intelligent algorithm selection and execution.

AI summary
A wearable data storage and transmission device and related systems that collect and store sensor data from sensors worn by a user. The device components can include a processor, battery, data storage media, NFC components, Bluetooth components, Wi-Fi components, and wired communications components. The device can remain powered down, powering up periodically to collect sensor data using low energy methods and/or in response to receiving a signal (e.g., NFC, power, Bluetooth, etc.) from an external device that causes the device to power up its components and make sensor data available to the external device. The collected sensor data may be encoded, compressed, stored, and/or exchanged in one or more structured records using various methods to improve the information storage capabilities of the device, including using the disclosed QR coding methods.
