Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If add-on devices are detachably connected to injection devices, then they can be used with various injection devices, but the device labels may be covered and manual calibration is required leading to potential errors
Solution Approach 1:
The add-on device performs preliminary actions by automatically reading the machine-readable identification code of the injection device and container upon attachment, obtaining device and container information before dose setting. This preliminary data acquisition enables automatic calibration of the dose-size-determination algorithm, eliminating manual calibration errors and ensuring accurate dose measurement from the start of use.
Solution Approach 2:
The add-on device serves itself by automatically acquiring device information and container information through its reader, and autonomously calibrating its dose determination algorithm using this information. The system performs self-calibration without requiring external manual intervention, thereby maintaining measurement precision while preserving versatility across different injection devices.
2Reliability
If manual calibration is required for add-on devices, then device information can be obtained, but it leads to potential errors and inefficiencies
Solution Approach 1:
The add-on device autonomously performs calibration by automatically reading the machine-readable identification code, extracting device and container information, and configuring its dose determination algorithm without requiring manual user intervention. This self-calibration process eliminates potential human errors while maintaining ease of operation.
Solution Approach 2:
The patent replaces manual mechanical calibration operations with an automated electronic system. The reader optically or electronically reads the machine-readable identification code, and the control unit automatically processes this data to calibrate the dose determination algorithm, substituting manual operations with automated electronic processes that are both more accurate and easier to use.
3Reliability
If automated detection and logging of dose injection is implemented, then security and convenience are improved, but device complexity increases
Solution Approach 1:
The add-on device integrates multiple functions into a single compact unit: the reader reads machine-readable identification codes, the sensor detects movable component positions, the control unit processes data and performs calculations, and the transceiver communicates with external devices. This multi-functional integration achieves automated detection and logging for improved security without proportionally increasing device complexity.
Solution Approach 2:
The transceiver acts as an intermediary that enables wireless communication between the add-on device and external electronic devices. This intermediary function allows the add-on device to log and transmit dose administration data automatically, improving security and convenience while keeping the add-on device itself relatively simple by offloading data storage and processing to external devices.
