Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an add-on device is designed to work with multiple injection devices, then versatility is improved, but device complexity increases due to the need for code recognition and adaptation mechanisms
Solution Approach 1:
The add-on device is designed with a universal code recognition unit that can detect and adapt to multiple types of injection devices (disposable and reusable) through different codes (first code on disposable devices, second code on reusable devices). This allows a single add-on device design to work across multiple device types without requiring separate specialized devices for each injection device type.
Solution Approach 2:
The code recognition unit acts as an intermediary between the add-on device and various injection devices. It detects the type of injection device through code detection and automatically adapts the add-on device's operation accordingly, serving as a mediator that translates between different injection device interfaces and the unified add-on device interface.
2Reliability
If manual dose logging is used, then device complexity is reduced, but reliability of medication monitoring deteriorates
Solution Approach 1:
The system enables automatic self-service monitoring where the add-on device automatically detects injection device attachment, reads the code to identify device type, and logs medication usage information without requiring manual user input. The system self-configures and self-monitors, eliminating the need for users to manually record doses while maintaining high reliability.
Solution Approach 2:
The system implements automated feedback loops where the add-on device continuously monitors injection device usage, detects code information, and automatically updates medication logs. This closed-loop feedback system ensures accurate tracking of medication administration without relying on user memory or manual recording, significantly improving monitoring reliability.
3Ease of operation
If a disposable injection device is used, then ease of operation is improved, but adaptability to different device types deteriorates
Solution Approach 1:
The add-on device achieves universality by incorporating a code recognition unit that can identify and adapt to both disposable injection devices (with first code) and reusable injection devices (with second code). This allows the add-on device to maintain simple, consistent operation across different device types while adapting its internal logic based on the detected code, effectively providing universal compatibility without sacrificing ease of use.
