Innovation Solution
A position determination device that uses a combination of sensors, including gyroscopes and accelerometers, to accurately determine and register injection locations, providing data on where and when injections occur, and includes a locking mechanism for secure attachment to the drug administration device, along with wireless communication for data transmission and indicator elements for user feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually track injection locations using memory or simple memory systems, then the device complexity is low, but the reliability of injection location management deteriorates due to poor compliance and forgotten injection sites
Solution Approach 1:
The patent replaces manual tracking methods (memory, paper diaries) with an automated electronic system that uses sensors, processors, and wireless communication to automatically detect, record, and manage injection locations. This substitution of mechanical/manual systems with electronic automation directly improves reliability while the complexity is managed through integrated design.
Solution Approach 2:
The system enables self-service by automatically tracking injection locations without requiring active user intervention for recording. The position determination element and processing units autonomously monitor and record injection sites, reducing reliance on user memory and manual documentation while improving compliance.
2Object-affected harmful factors
If users rotate injection locations to avoid tissue damage, then the health outcome improves, but the difficulty of detecting and measuring injection locations worsens due to the need for precise location tracking
Solution Approach 1:
The patent uses electronic sensors and processing units to automatically detect and record injection locations, replacing the need for manual visual assessment and memory-based tracking. This electronic detection system makes precise location measurement straightforward, enabling effective rotation schemes to prevent tissue damage.
Solution Approach 2:
The system provides feedback by recording injection locations and notifying users when a previously injected area is selected again. The processing unit compares current injection location data with historical data and alerts users through the output interface, preventing repeated injections in the same area and avoiding tissue damage.
3Measurement precision
If precise data about actual injection locations is collected, then the measurement precision improves, but the device complexity worsens due to additional sensors and processing requirements
Solution Approach 1:
The patent integrates multiple functions into a single device: the position determination element not only tracks location but also records timing, stores data in memory, and communicates wirelessly. This multi-functionality achieves precise measurement while managing complexity through integration rather than separate components for each function.
Solution Approach 2:
The system merges the position determination element, processing units, memory storage, and wireless communication into an integrated apparatus. This consolidation achieves precise injection location tracking while reducing overall system complexity compared to having separate independent systems for each function.
