Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device performs scanning operations for multiple communication protocols simultaneously, then the device can discover more external electronic devices, but scan resources are duplicated and wasted
Solution Approach 1:
The patent segments the scanning process by dividing external electronic devices into different groups based on their communication protocols (e.g., Wi-Fi devices, Bluetooth devices). The electronic device then performs scanning operations separately for each group using protocol-specific scanning methods, avoiding the waste of resources that would occur if all protocols were scanned simultaneously or uniformly.
Solution Approach 2:
The patent changes the scanning parameters dynamically based on the target external electronic device. By identifying the communication protocol of the target device first, the system adjusts the scanning parameters (such as scanning frequency, duration, and method) to match the specific protocol requirements, thereby optimizing resource utilization while maintaining comprehensive device discovery capability.
2Reliability
If the electronic device scans all possible external electronic devices, then no desired device is missed, but scan performance deteriorates due to resource duplication and ambient interference
Solution Approach 1:
The patent applies preliminary action by first identifying the communication protocol of the target external electronic device before performing the actual scanning operation. This preliminary identification step allows the system to prepare appropriate scanning strategies and resources in advance, ensuring that the subsequent scanning is both comprehensive and efficient, thus maintaining reliability while improving productivity.
Solution Approach 2:
The patent implements partial action by performing scanning operations only for the communication protocols that are relevant to the target external electronic device. Instead of exhaustively scanning all possible protocols, the system selectively applies scanning methods based on protocol identification, achieving sufficient device discovery without the performance penalty of excessive scanning operations.
3Adaptability or versatility
If the electronic device uses multiple communication protocols for scanning, then more external devices can be discovered, but the complexity of scan resource management increases
Solution Approach 1:
The patent implements a universal scanning framework that can handle multiple communication protocols through a common interface and management mechanism. The system maintains a protocol identification module that recognizes different protocols and routes scanning operations through appropriate handlers, allowing the electronic device to support multiple protocols without proportionally increasing the complexity of resource management.
Solution Approach 2:
The patent introduces an intermediary protocol identification module that acts as a mediator between the scanning system and multiple communication protocols. This intermediary component identifies the target device's protocol and coordinates the scanning resources accordingly, simplifying the overall management complexity by centralizing the protocol-handling logic rather than requiring separate management systems for each protocol.
