Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the wearable detecting apparatus is used for long-term monitoring, then the duration of action is improved, but measurement precision deteriorates due to dislocation and environmental changes
Solution Approach 1:
The system performs preliminary actions by continuously monitoring physiological parameters and establishing baseline data before abnormal conditions occur. The processor proactively identifies trends and potential issues, allowing the system to take preventive measures or alert users before measurement accuracy deteriorates significantly due to dislocation or environmental changes.
Solution Approach 2:
The system implements feedback mechanisms by continuously comparing measured physiological values against reference ranges and historical data. When dislocation or environmental changes cause measurement drift, the feedback loop detects these deviations and triggers corrective actions, such as notifying the user to reposition the device or adjusting measurement parameters to maintain accuracy over long-term usage.
2Ease of operation
If the detecting apparatus performs simplified operations for portability, then ease of operation is improved, but measurement precision deteriorates due to reduced detection capabilities
Solution Approach 1:
The detecting apparatus applies self-service by automatically performing calibration, noise filtering, and abnormal value identification without requiring user intervention. The processor autonomously processes raw optical signals, applies algorithms to identify abnormal physiological values, and replaces them with reliable values, maintaining measurement precision while keeping the device simple for users to wear and operate.
Solution Approach 2:
The system dynamically changes measurement parameters such as optical signal wavelengths, pulsing frequencies, and detection sensitivity based on ambient conditions and user activity. This allows the simplified wearable device to maintain high measurement precision by adapting its detection parameters in real-time without requiring complex user configuration or manual adjustment.
3Measurement precision
If the detecting apparatus continuously monitors physiological information, then measurement precision is improved, but use of energy increases leading to reduced battery endurance
Solution Approach 1:
The detecting apparatus implements periodic action by measuring physiological parameters at optimized intervals rather than continuously. The processor analyzes trends in physiological data and adjusts the measurement frequency dynamically, performing more frequent measurements when changes are detected and reducing frequency during stable periods, thereby maintaining measurement precision while significantly reducing overall power consumption for extended battery operation.
4Measurement precision
If the detecting apparatus processes and replaces abnormal physiological values, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The processing system applies self-service by autonomously identifying abnormal physiological values through built-in algorithms and automatically replacing them with reliable values derived from historical data or alternative measurement methods. This self-contained approach maintains high measurement precision without requiring external intervention or complex user-facing controls, keeping the device interface simple despite sophisticated internal processing.
