Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual insertion guidance is provided, then ease of operation is improved, but reliability of optimal positioning is worsened due to user variability
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated sensor-based system. Orientation sensors (accelerometers, gyroscopes) detect the device's angular position in the nostril and send data to a mobile device that provides real-time feedback, eliminating reliance on user skill and ensuring consistent optimal positioning.
Solution Approach 2:
The system implements a feedback loop where orientation sensors continuously monitor device positioning, the mobile device processes this data to determine optimal orientation, and provides real-time visual or audible feedback to guide the user in achieving and maintaining the correct position for reliable medication delivery.
2Productivity
If automated actuation is implemented, then productivity is improved, but device complexity is worsened
Solution Approach 1:
The patent replaces manual mechanical actuation with an automated motorized system. A motor driven by a microcontroller automatically actuates the dispensing mechanism when optimal positioning is detected, eliminating the need for manual button pressing and ensuring precise timing of medication delivery.
Solution Approach 2:
The system performs self-service by automatically detecting optimal positioning through sensors and triggering actuation without user intervention. The device monitors its own orientation and autonomously executes the dispensing action when conditions are met, improving efficiency while keeping the interface simple.
3Measurement precision
If orientation sensors are added, then measurement precision is improved, but device complexity is worsened
Solution Approach 1:
The patent leverages the multi-functionality of modern mobile devices that already contain orientation sensors for other purposes (screen rotation, step counting). By utilizing these existing sensors and their associated processing capabilities, the system achieves precise orientation measurement without adding dedicated sensor hardware, thereby minimizing complexity increase.
