Aerosol Device BTLE Advertising Packet Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data communication methods for aerosol delivery devices, such as electronic nicotine delivery devices, often require connection-based protocols like Bluetooth, which consume more energy and are less efficient for data logging and predictive maintenance.
Innovation Solution
The method involves using a connectionless communication link via BTLE or BTLE-like protocols to transmit advertising and response packets from an aerosol delivery device, including usage characteristics like battery status and error codes, without establishing a formal connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection-based protocols like Bluetooth are used for data communication, then reliable data transmission is achieved, but energy consumption increases
Solution Approach 1:
The patent segments the communication process into two distinct modes: connection-based communication for reliable data transmission, and connectionless advertising for energy-efficient status broadcasting. The aerosol delivery device can selectively use advertising mode for routine status updates (battery level, usage characteristics) to conserve energy, while switching to connection-based mode when reliable bidirectional communication is needed
Solution Approach 2:
The device implements periodic advertising transmissions at configurable intervals, allowing it to broadcast status information without maintaining a continuous connection. This periodic approach reduces energy consumption compared to continuous connection-based protocols while still providing regular updates to paired devices
2Adaptability or versatility
If connection-based protocols are used, then comprehensive data exchange is enabled, but device complexity increases
Solution Approach 1:
The patent implements a universal communication framework where a single advertising mechanism can convey multiple types of information (battery status, usage characteristics, error codes, device identity) through standardized packet formats. This multi-functional advertising approach reduces the need for separate communication channels for different data types, simplifying the overall system while maintaining versatility
3Use of energy by moving object
If connectionless communication is used, then energy efficiency improves, but data transmission reliability may deteriorate
Solution Approach 1:
The patent introduces a paired device (smartphone, tablet, or base station) as an intermediary that receives advertising packets from the aerosol delivery device and manages data storage, processing, and forwarding. This intermediary handles the complexity of reliable data aggregation and can retransmit information as needed, allowing the aerosol device itself to use energy-efficient connectionless advertising without sacrificing overall system reliability
