Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device scans all external electronic devices using all communication protocols, then the discovery capability is comprehensive, but the scan resources are wasted and scan time increases
Solution Approach 1:
The patent applies local quality by making the scan configuration protocol-specific. Each communication protocol (e.g., Bluetooth, Wi-Fi, Zigbee) has its own dedicated scan parameters including scan interval, scan window, and filter settings. This allows the device to optimize scan resources for each protocol individually rather than using a uniform configuration, thereby reducing overall resource consumption while maintaining comprehensive discovery capability across different protocol types.
Solution Approach 2:
The patent segments the scan operation by protocol type. Instead of performing a single monolithic scan across all protocols simultaneously, the system divides the discovery process into separate scan operations for each communication protocol. This segmentation allows independent optimization of scan parameters for each protocol and enables selective activation of scans based on which protocols are actually supported by target devices, reducing unnecessary resource expenditure.
2Adaptability or versatility
If the electronic device scans all external electronic devices using all communication protocols, then the discovery capability is comprehensive, but the scan time increases
Solution Approach 1:
The patent implements dynamic scan time adjustment based on protocol characteristics and environmental conditions. The scan interval and scan window for each communication protocol are not fixed but can be dynamically modified. For example, if Bluetooth Low Energy (BLE) devices are detected or expected, the system can increase the BLE scan window and decrease the interval, while reducing resources allocated to protocols that are not supported by nearby devices. This dynamic adaptation reduces total scan time while maintaining comprehensive discovery capability.
Solution Approach 2:
The patent changes scan parameters (interval, window, filters) based on the identified communication protocols of target devices. When the system determines which protocols are supported by external devices in the environment, it adjusts the scan parameters accordingly - increasing scan frequency for supported protocols and decreasing or suspending scans for unsupported protocols. This parameter optimization significantly reduces the time required to discover devices while ensuring all relevant devices are found.
3Ease of operation
If the electronic device performs scan operations without considering protocol support, then the scan operation is simple, but the scan performance is inefficient
Solution Approach 1:
The patent implements self-service by enabling the electronic device to automatically identify which communication protocols are supported by external devices and autonomously adjust its scan configuration accordingly. The system performs protocol detection, analyzes the results, and modifies scan parameters without requiring manual user input or configuration. This self-adjusting mechanism maintains operational simplicity for the user while dramatically improving scan performance through protocol-optimized scanning.
Solution Approach 2:
The patent incorporates feedback loops where the scan results from protocol detection are fed back into the scan configuration system. The device scans for external devices, identifies their supported communication protocols based on response characteristics, and uses this feedback information to adjust subsequent scan parameters. This closed-loop approach automatically optimizes scan performance based on real-time environmental conditions while keeping the operation simple for the user.
