Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If remote alert systems and sensors are used to remind patients to take medication, then patient awareness of medication schedules is improved, but actual medication adherence cannot be verified
Solution Approach 1:
The system implements feedback by using weight sensors to continuously monitor medication containers and provide real-time data on whether medication has been taken. The scale measures weight changes in the container, automatically verifying adherence without relying on patient self-reporting, thus closing the feedback loop between medication dispensing and verification.
Solution Approach 2:
The system enables self-service by having the medication monitoring system automatically track and verify its own usage through integrated weight sensors. The system independently monitors whether medication has been taken by detecting weight changes, eliminating the need for external verification or patient manual input, thus making the adherence verification self-sufficient.
2Loss of information
If cap sensors are used to detect when medication containers are opened, then medication access is monitored, but actual dosage taken cannot be determined
Solution Approach 1:
The system implements feedback by using weight sensors to continuously monitor medication containers and provide real-time data on whether medication has been taken. The scale measures weight changes in the container, automatically verifying adherence without relying on patient self-reporting, thus closing the feedback loop between medication dispensing and verification.
Solution Approach 2:
The system replaces the mechanical cap sensor approach with a weight-based measurement system. Instead of detecting cap removal mechanically, the system uses electronic weight sensors to precisely measure dosage changes by detecting weight differences before and after medication dispensing, providing quantitative dosage verification.
3Ease of operation
If refrigerator trays are used to store liquid medications, then medication organization is improved, but dosage monitoring capability is lost
Solution Approach 1:
The system merges the medication storage organization function of refrigerator trays with the dosage monitoring capability of weight sensors. The tray structure provides organized storage for liquid medication containers while integrated weight sensors continuously measure weight changes, combining storage convenience with precise dosage tracking in a single unified system.
Solution Approach 2:
The system achieves multi-functionality by designing a refrigerator tray that simultaneously provides medication organization and dosage monitoring. The tray serves dual purposes: organizing liquid medication containers for easy access and continuously measuring weight changes to track dosage consumption, eliminating the need for separate monitoring devices.
4Adaptability or versatility
If patients are responsible for measuring loose powder medications, then medication flexibility is maintained, but dosage accuracy deteriorates
Solution Approach 1:
The system implements feedback by using weight sensors to continuously monitor medication containers and provide real-time data on whether medication has been taken. The scale measures weight changes in the container, automatically verifying adherence without relying on patient self-reporting, thus closing the feedback loop between medication dispensing and verification.
Solution Approach 2:
The system replaces manual patient measurement with automated electronic weight sensing. Instead of relying on patients to manually measure loose powder medications, the system uses precision weight sensors to automatically detect and record dosage changes, maintaining dispensing flexibility while ensuring accurate dosage measurement.
