Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric sensors (optical sensor for fingerprint and heart rate) are integrated into the aerosol generating apparatus, then security and user verification capability are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions (aerosol generation, fingerprint sensing, heart rate monitoring, and user verification) into a single integrated device. The optical sensor serves dual purposes by capturing both fingerprint patterns and heart rate information through the same hardware component, reducing the need for separate sensors and simplifying the overall device architecture.
Solution Approach 2:
The optical sensor is designed to perform multiple functions: it captures reflected optical signals to extract both fingerprint information and heart rate data. This multi-functional approach allows a single component to fulfill multiple verification and monitoring roles, thereby improving security capabilities without proportionally increasing device complexity.
2Measurement precision
If multiple sensors (optical sensor, security sensor) are integrated to obtain biometric information, then measurement capability is improved, but device complexity increases
Solution Approach 1:
The patent merges fingerprint sensing and heart rate monitoring capabilities into a single optical sensor system. By using the same optical sensor to capture both types of biometric data through different signal processing approaches, the device achieves comprehensive measurement capability without the complexity of multiple separate sensors.
Solution Approach 2:
The optical sensor is designed as a universal sensing component that can extract multiple types of biometric information (fingerprint patterns and heart rate variations) from the same optical signal source. This approach enhances measurement precision across different biometric parameters while maintaining a simplified sensor architecture.
3Productivity
If the apparatus controls power to the heater based on heart rate information, then operation optimization is improved, but processing complexity increases
Solution Approach 1:
The patent implements a feedback control mechanism where the processor continuously monitors heart rate information obtained from the optical sensor and dynamically adjusts the power supplied to the heater accordingly. This closed-loop control optimizes the aerosol generation process based on real-time physiological data, improving operational efficiency and user experience.
Solution Approach 2:
The system uses the user's own physiological data (heart rate) to automatically adjust its operation parameters (heater power). This self-service approach allows the device to adapt to the user's state without requiring manual input or complex external control systems, simplifying the overall control architecture while achieving operation optimization.
