Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed user-friendly identifier is provided on the data logger, then identification is simplified for users, but flexibility and efficiency are reduced
Solution Approach 1:
The identification system is segmented into two parts: a fixed device identifier on the data logger and a separate personal identifier from the back-end unit. This segmentation allows the device to maintain a simple fixed identifier for basic operation while enabling flexible personal identification through the separate personal identifier that can be assigned to different users.
Solution Approach 2:
The pairing unit acts as an intermediary that links the fixed device identifier with the personal identifier from the back-end unit. This intermediary mechanism enables the system to maintain both the simplicity of a fixed identifier and the flexibility of personalized identification by mediating between the two identifier types.
2Ease of operation
If a fixed user-friendly identifier is provided on the data logger, then user identification is simplified, but efficiency in handling incontinence is reduced
Solution Approach 1:
By segmenting the identification into a fixed device identifier and a separate personal identifier, the system maintains operational simplicity while enabling efficient user-specific data tracking and management, thereby improving handling efficiency without sacrificing ease of use.
Solution Approach 2:
The system transitions from a static fixed identifier to a dynamic identification system where the personal identifier can be changed and reassigned. This dynamic capability allows the system to adapt to different users and situations, improving efficiency in handling incontinence while maintaining the simplicity of the fixed device identifier for basic operations.
3Reliability
If sensing capabilities and monitoring units are added to the identification device, then monitoring and management capabilities are enhanced, but device complexity increases
Solution Approach 1:
The sensing capabilities and monitoring units are merged with the identification device in such a way that they share common components and processing resources. The processor that handles identification also processes sensor data, and the communication unit that transmits identification information also transmits monitoring data, thereby enhancing monitoring capabilities without proportionally increasing device complexity.
Solution Approach 2:
The identification device is designed with multi-functionality, where the same hardware components serve multiple purposes. The processor handles both identification and sensing tasks, the communication unit transmits both identification and monitoring data, and the power supply supports both functions, thereby reducing the overall device complexity while enhancing monitoring capabilities.
4Adaptability or versatility
If multiple communication means for short-range and long-range communication are integrated, then communication flexibility and remote monitoring are improved, but device complexity and energy consumption increase
Solution Approach 1:
The communication unit employs periodic action by switching between short-range and long-range communication modes based on operational needs. Short-range communication is used for frequent, low-energy data transmission during active monitoring, while long-range communication is activated periodically for remote data synchronization, thereby reducing overall energy consumption while maintaining communication flexibility.
Solution Approach 2:
The communication system implements self-service by automatically selecting the appropriate communication mode (short-range or long-range) based on the current operational context. The device autonomously decides when to use energy-efficient short-range communication and when to activate long-range communication for remote monitoring, thereby optimizing energy consumption without requiring manual intervention or increasing device complexity.
