Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user holds an external electronic device in one hand and the injection device in the other hand to receive assistance, then the user can receive instructions or recommendations, but the user may accidentally cause stitch damage when entering commands on the external electronic device
Solution Approach 1:
The injection device itself serves as an intermediary input device. The sensor assembly detects user gestures (such as pressing buttons or touching the device surface) and automatically translates them into control signals for the external electronic device, eliminating the need for the user to manually input commands on the external device while holding the injection device
Solution Approach 2:
The injection device autonomously captures gesture inputs from the user and self-translates them into appropriate control signals for the external electronic device, reducing the cognitive and physical burden on the user
2Loss of information
If complex input methods are used on external electronic devices for medication assistance, then monitoring and logging can be achieved, but the operation becomes complicated and cumbersome for users
Solution Approach 1:
Complex manual input operations are replaced by simple gesture detection. The sensor assembly automatically detects and interprets user gestures (such as button presses or touch interactions) and converts them into structured control signals for monitoring and logging functions on the external electronic device
Solution Approach 2:
The system provides automatic feedback loops where the sensor detects user gestures, the processor interprets them, and the external electronic device receives appropriate control signals for monitoring and logging, creating a seamless automated interaction that reduces user burden while maintaining data accuracy
