Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the mobile terminal uses a single processor (AP) for both active mode operations and Bluetooth data processing, then the device structure remains simple, but the processor cannot process Bluetooth data immediately when in sleep mode, causing data processing delays
Solution Approach 1:
The patent divides the processing system into two separate processors: a first processor (AP) for active mode operations and a second processor (low-power processor) for sleep mode Bluetooth data processing. This segmentation allows each processor to be optimized for its specific function, enabling immediate Bluetooth data processing in sleep mode without requiring the AP to wake up, thus reducing data processing delay while maintaining reasonable device complexity through functional separation.
2Reliability
If the AP stays in active mode to periodically receive data from Bluetooth, GPS, and Wi-Fi, then data reception is continuous, but periodic signal scanning causes significant power consumption
Solution Approach 1:
The patent segments the power consumption responsibilities by assigning the second processor (low-power processor) to handle Bluetooth data reception in sleep mode, while the first processor (AP) remains in active mode only when needed for other operations. This allows continuous Bluetooth data reception without keeping the entire AP active, significantly reducing power consumption while maintaining data reception reliability through the dedicated low-power processor.
Solution Approach 2:
The second processor is designed to autonomously handle Bluetooth data reception and initial processing in sleep mode without requiring the AP to wake up. This self-service capability allows the system to maintain continuous Bluetooth monitoring while the AP remains in low-power state, reducing overall power consumption while ensuring reliable data reception through the dedicated low-power processor.
3Loss of energy
If the mobile terminal enters sleep mode to reduce power consumption, then battery span increases, but the terminal cannot process Bluetooth data immediately even when received successfully
Solution Approach 1:
The patent segments processing responsibilities between two processors: the first processor (AP) that enters sleep mode to conserve battery, and a second processor (low-power processor) that remains active to immediately process Bluetooth data. This segmentation allows the system to achieve both low battery consumption (through AP sleep mode) and immediate data processing (through the always-on second processor), resolving the contradiction between energy savings and processing speed.
4Use of energy by moving object
If the AP cuts off power to function blocks and communication interface in sleep mode, then power consumption decreases, but the terminal cannot use functions connected to the AP including Bluetooth processing
Solution Approach 1:
The patent segments the system into two independent processing paths: one through the first processor (AP) for active mode functions, and another through the second processor (low-power processor) for sleep mode Bluetooth functions. This segmentation allows the system to maintain Bluetooth functionality in sleep mode by routing it through the second processor, which remains operational even when the AP cuts power to its connected function blocks, thus preserving function availability while reducing power consumption.
Solution Approach 2:
The second processor acts as an intermediary that enables Bluetooth data processing to continue in sleep mode independently of the AP's power state. This intermediary processor receives and processes Bluetooth data even when the AP has cut off power to its connected function blocks, maintaining Bluetooth adaptability and functionality during sleep mode without requiring the AP to remain active.
