Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the wearable device is made small and compact, then it is less intrusive and more convenient for daily wear, but the battery capacity is limited requiring frequent charging
Solution Approach 1:
The transceiver is activated periodically based on predetermined patterns rather than continuously. The processor module compares sensor data to predetermined patterns and only activates the transceiver when conditions are met, creating a periodic activation cycle that reduces overall power consumption while maintaining necessary communication functionality.
Solution Approach 2:
The wearable device autonomously determines when to activate the transceiver by comparing sensor data against predetermined patterns stored in the processor module. This self-service mechanism eliminates the need for continuous user input or manual activation, allowing the device to automatically optimize its power usage based on actual usage conditions.
2Use of energy by moving object
If high power components such as transceiver remain off as long as possible, then power consumption is reduced and battery life is extended, but data transmission cannot be initiated when needed
Solution Approach 1:
The processor module continuously monitors sensor data and compares it against predetermined patterns to determine when transceiver activation is appropriate. This feedback mechanism ensures the transceiver is activated only when actual usage conditions warrant it, optimizing the balance between power conservation and operational readiness.
Solution Approach 2:
The device pre-establishes predetermined patterns in the processor module that define when data transmission should occur. These patterns are configured in advance based on expected usage scenarios, allowing the transceiver to be activated proactively when conditions match the predetermined criteria rather than waiting for user initiation.
3Productivity
If periodic sync is performed on a set time base, then data is regularly uploaded to mobile devices, but a lot of power is consumed
Solution Approach 1:
The synchronization frequency is made dynamic rather than fixed. The transceiver activation is adjusted based on real-time comparison of sensor data against predetermined patterns, allowing the system to synchronize data at variable intervals that adapt to actual usage conditions rather than following a rigid time-based schedule.
4Reliability
If the transceiver is actively listening for connection requests, then data can be transmitted when needed, but power consumption increases significantly
Solution Approach 1:
The continuous listening function is extracted from the normal operation mode. Instead of the transceiver continuously monitoring for connection requests, it is only activated when the processor module determines that predetermined patterns are met, separating the power-intensive listening function from continuous operation and limiting it to specific triggered events.
Data Source
AI summary
The disclosure discloses a wearable computing device (WCD) that would selectively and automatically activate a transceiver of the WCD for data transmission based on sensor data obtained from a sensor module of the \VCD. In some example, the sensor module may convert the physical movements of the WCD into sensor data. Then, a processor module of the WCD compares the sensor data to a predetermined pattern pre-stored in the memory. If the sensor data matches the predetermined pattern, the processor module activates the transceiver to receive/transmit data packets. If the sensor data does not match the predetermined pattern, the process goes back to the beginning, where the processor module monitors the movement of the WCD through the sensors.
