Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device operates continuously to transmit RFID signals and monitor motion, then the functionality and reliability are improved, but the battery power is depleted quickly
Solution Approach 1:
The device implements periodic operation by cycling through sleep mode, sampling mode, analysis mode, monitoring mode, and transmission mode. The microprocessor activates from sleep mode to sampling mode periodically, enabling continuous operation while conserving battery power during inactive periods.
Solution Approach 2:
The device dynamically adjusts its operational state based on detected motion activity. The multi-axis accelerometer monitors motion continuously, and when motion is detected, the system transitions from low-power sleep mode to active sampling and analysis modes, optimizing power consumption according to actual usage conditions.
2Productivity
If the microprocessor and accelerometer are activated frequently to detect motion and transmit data, then the responsiveness and functionality are improved, but the battery power is depleted faster
Solution Approach 1:
The device performs preliminary action by continuously monitoring motion activity in a low-power state using the accelerometer. When motion is detected, the system is already prepared to quickly transition to sampling and transmission modes, eliminating delays while minimizing power consumption during the monitoring phase.
Solution Approach 2:
The device maintains continuity of useful action by continuously monitoring motion activity through the accelerometer while in sleep mode, and seamlessly transitioning to active modes when needed. This ensures no data is missed while keeping power consumption minimal during inactive periods.
3Measurement precision
If the device uses sophisticated components with varying power requirements, then the functionality and measurement precision are improved, but the battery power is depleted more quickly
Solution Approach 1:
The device applies local quality by using the multi-axis accelerometer for continuous low-power motion monitoring, and only activating the microprocessor and radiofrequency components when motion is detected. This allows high-precision measurement capabilities to be available on-demand while minimizing power consumption during normal operation.
