Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are integrated into the medication delivery device to detect and analyze dispensing events, then measurement precision and reliability are improved, but device complexity increases
Solution Approach 1:
The electronic module is designed as a separate, detachable unit that can be coupled to the medication delivery device. This segmentation allows the sensing and data processing functions to be isolated from the main injection mechanism, reducing the complexity of the primary device while maintaining high measurement precision through dedicated electronic components.
Solution Approach 2:
The electronic module acts as an intermediary between the mechanical injection components and the data analysis system. It contains the sensor elements that detect dispensing events and converts mechanical signals into electronic data, serving as a bridge that improves measurement precision without directly complicating the core medication delivery mechanism.
2Loss of information
If multiple sensor types are used to detect various dispensing characteristics, then information completeness is improved, but device complexity increases
Solution Approach 1:
The electronic module is designed with multi-functionality, capable of accommodating multiple types of sensors (acoustic, vibration, force) within a single integrated unit. This universal design allows the system to capture comprehensive dispensing event information through various sensing modalities without requiring separate devices for each function, thus improving information completeness while managing complexity through consolidation.
3Ease of operation
If the electronic module is designed as detachable and portable, then ease of operation is improved, but reliability of coupling may worsen
Solution Approach 1:
The coupling mechanism between the electronic module and medication delivery device is designed to be dynamically adjustable. It provides secure attachment during operation to ensure reliable signal detection and data collection, while allowing easy detachment when not in use. This dynamic coupling capability enables the system to switch between ease of operation and reliability based on the operational state.
