Aerosol Nebulizer Control with Identifier-Based Data Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control devices for aerosol nebulizers lack mechanisms to ensure data completeness and integrity of usage data transmission, particularly in wireless communication environments, which can lead to loss or incomplete data sets when multiple devices are used, affecting adherence to therapy protocols.
Innovation Solution
Implementing a data integrity mechanism that includes a circular buffer for storing aerosol nebulizer data units with unique identifiers, and a verification system to ensure complete data transmission by evaluating the sequence of received identifiers, allowing for re-transmission of missing data units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used for data transmission between control device and aerosol nebulizer, then ease of operation and mobility are improved, but data completeness and reliability deteriorate due to potential data loss in wireless environments
Solution Approach 1:
The patent implements preliminary action by storing usage data in a circular buffer with sequential identifiers before transmission. This allows the receiving device to detect missing data units based on identifier sequences and request retransmission, ensuring data completeness while maintaining wireless mobility.
Solution Approach 2:
The patent employs feedback mechanisms where the control device evaluates the sequence of received identifiers to detect missing data units and triggers retransmission requests. This feedback loop ensures reliable data collection despite wireless communication uncertainties, resolving the contradiction between mobility and data reliability.
2Reliability
If multiple control devices are used to monitor therapy, then adherence tracking reliability is improved, but data consistency and completeness worsen due to potential data loss across multiple devices
Solution Approach 1:
The patent applies preliminary action by pre-numbering data units with sequential identifiers before transmission to multiple control devices. This enables any receiving device to identify missing data units by checking the identifier sequence, ensuring data consistency across multiple devices without requiring complex synchronization protocols.
Solution Approach 2:
The patent implements universality by designing a data transmission system where multiple control devices can independently receive and validate usage data using the same identifier-based verification mechanism. This universal approach ensures data consistency across multiple devices while maintaining adherence tracking reliability.
3Reliability
If data retransmission is implemented to ensure completeness, then data reliability is improved, but transmission time and energy consumption increase
Solution Approach 1:
The patent uses preliminary action by pre-assigning sequential identifiers to data units in the circular buffer before transmission. This enables the receiving device to quickly identify missing data units through simple sequence evaluation rather than complex verification, minimizing retransmission overhead and time loss while ensuring data completeness.
