Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a medicament delivery device is equipped with sensor and logging devices to track user behavior, then user behavior tracking capability is improved, but device complexity increases
Solution Approach 1:
The sensor device serves multiple functions: detecting motion, determining orientation, and tracking user behavior patterns. By making the sensor system multi-functional, the patent reduces the need for separate dedicated sensors for each function, thereby improving user behavior tracking capability while minimizing the increase in device complexity.
Solution Approach 2:
The patent introduces a processing unit as an intermediary that receives data from sensors and generates user behavior patterns. This intermediary layer simplifies the overall system architecture by centralizing data processing and interpretation, allowing the sensor device to track user behavior effectively without requiring complex direct connections between all components.
2Measurement precision
If motion detection sensors are added to the medicament delivery device, then user handling analysis is improved, but manufacturing cost increases
Solution Approach 1:
The patent implements the sensor device and logging device in a disposable hub assembly that is discarded after use. This approach allows the use of precision motion detection sensors without concern for long-term durability or recalibration, as the entire assembly is replaced after a single use. The low cost of the disposable unit offsets the expense of precision sensors, resolving the contradiction between measurement precision and manufacturing cost.
3Speed
If real-time data transmission is implemented, then real-time feedback capability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic data transmission where the logging device transmits user behavior patterns at scheduled intervals rather than continuously. This periodic transmission approach maintains real-time feedback capability for analysis while significantly reducing energy consumption compared to continuous transmission, as the communication module remains inactive between transmission cycles.
