Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the processor is activated to manage find network devices through Bluetooth chips, then the interaction between electronic device and find network device is achieved, but power consumption increases
Solution Approach 1:
The patent divides the management function into two segments: the processor handles high-level pairing and connection establishment, while the microcontroller unit handles low-level status management and broadcast message scanning. This segmentation allows the processor to remain dormant during status management operations, reducing power consumption while maintaining interaction capability.
Solution Approach 2:
The microcontroller unit acts as an intermediary between the processor and the Bluetooth chip for status management operations. It receives accessory management information from the processor, performs status management independently, and communicates with the Bluetooth chip without requiring processor activation, thus reducing power consumption while enabling continuous interaction.
2Use of energy by moving object
If the processor remains dormant to save power, then power consumption is reduced, but status management capability is limited
Solution Approach 1:
The patent segments status management capabilities between the processor and microcontroller unit. The microcontroller unit independently performs status management operations including broadcast message scanning and connection state monitoring, enabling continuous productivity without processor activation.
Solution Approach 2:
The microcontroller unit performs self-service status management by autonomously scanning broadcast messages, determining find network device states, and managing connections without requiring processor intervention. This enables the system to maintain full status management capability while the processor remains dormant for power saving.
3Reliability
If continuous monitoring of find network devices is performed, then device availability is improved, but power consumption increases
Solution Approach 1:
The patent segments the monitoring function by implementing continuous broadcast message scanning at the microcontroller unit level while keeping the processor dormant. The microcontroller unit independently monitors device availability through broadcast messages and maintains connection states without requiring processor activation, thus ensuring reliability while minimizing power consumption.
