Data Transmitting Apparatus Unidirectional Confidentiality Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blood pressure monitors using Bluetooth Low Energy (BLE) for data transmission face challenges such as user complexity in operations, hardware requirements, high development costs, and unsuitability for low-capacity data transmissions, leading to potential data loss and confidentiality issues due to unidirectional communication limitations.
Innovation Solution
A data transmitting apparatus that selectively transmits first and second data packets through unidirectional communication, allowing for confidential data transmission only when the user intentionally approaches the device, ensuring high confidentiality and reducing data loss by switching between non-confidential and confidential data transmission based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If unidirectional communication is used for data transmission, then power consumption is reduced and device complexity is lowered, but data confidentiality deteriorates and data loss risk increases
Solution Approach 1:
The patent implements dynamic switching between advertisement packet transmission modes: normal mode for general data and confidential mode for sensitive data. The transmission control unit dynamically adjusts transmission behavior based on data type identification, enabling the system to adapt its communication characteristics to protect confidentiality when needed while maintaining low power consumption during normal operation.
Solution Approach 2:
The patent applies different transmission qualities to different data types. Confidential data receives enhanced transmission protection through dedicated confidential advertisement packets with stricter transmission control, while non-confidential data uses standard advertisement packets. This local differentiation of transmission quality allows the system to protect confidentiality without compromising the overall efficiency of unidirectional communication.
2Device complexity
If unidirectional communication is used for data transmission, then device complexity is reduced, but data loss risk increases due to inability to confirm reception
Solution Approach 1:
The patent implements a feedback mechanism where the blood pressure monitor transmits not only measurement data but also reception status information about advertisement packets. This feedback allows the monitor to determine whether data was successfully received by the portable terminal, enabling the system to compensate for the lack of bidirectional communication by monitoring transmission outcomes and adjusting subsequent transmission attempts accordingly.
3Ease of operation
If advertisement packets are used for data transmission, then ease of operation is improved by eliminating pairing requirements, but data confidentiality deteriorates due to open transmission
Solution Approach 1:
The patent segments advertisement packets into different types: normal advertisement packets for general data transmission and confidential advertisement packets for sensitive data. This segmentation allows the system to maintain the ease of operation benefits of unidirectional communication while selectively applying confidentiality protection to specific data types through dedicated packet handling and transmission control.
