Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If time division multiplexing is used to switch between Wi-Fi and Wi-Fi Direct channels, then both communication types can operate simultaneously, but transmission speed decreases due to frequent channel switching
Solution Approach 1:
The patent merges Wi-Fi and Wi-Fi Direct communications onto the same channel when possible, eliminating the need for channel switching between the two communication types. This is achieved by having the wireless communication unit perform both communications on a common channel, thereby maintaining high transmission speed while supporting both communication modes simultaneously.
Solution Approach 2:
The patent dynamically adjusts channel allocation based on communication status. When Wi-Fi Direct communication is not active, the channel is allocated to Wi-Fi communication. When Wi-Fi Direct communication starts, the channel is dynamically switched to support P2P communication. This dynamic allocation optimizes transmission speed by minimizing unnecessary channel switching while maintaining adaptability to different communication scenarios.
2Reliability
If different channels are used for Wi-Fi and Wi-Fi Direct communications, then channel congestion can be avoided, but device complexity increases due to channel management
Solution Approach 1:
The wireless communication unit automatically determines whether to use the same channel or different channels for Wi-Fi and Wi-Fi Direct communications based on the communication status. The system self-manages channel allocation without requiring complex external control, by checking whether P2P communication is active and automatically switching channels accordingly, thereby reducing device complexity while maintaining communication reliability.
Solution Approach 2:
The patent implements feedback mechanisms where the wireless communication unit continuously monitors the status of P2P communication and adjusts channel allocation based on this feedback. When P2P communication status changes, the system receives feedback and automatically switches channels to avoid congestion, maintaining reliable communication without requiring complex manual channel management.
3Adaptability or versatility
If channel switching is performed frequently to support both communication types, then adaptability is improved, but transmission speed decreases due to switching overhead
Solution Approach 1:
The patent combines Wi-Fi and Wi-Fi Direct communications on the same channel to eliminate switching overhead. By merging the channel usage of both communication types, the system achieves high productivity without sacrificing adaptability, as the channel is dynamically allocated based on which communication type is currently active.
Solution Approach 2:
The patent ensures continuous useful action by maintaining the communication channel in an active state for both Wi-Fi and Wi-Fi Direct communications. Instead of switching channels frequently, the system keeps the channel continuously available and dynamically allocates it based on communication needs, eliminating switching overhead and maintaining high communication efficiency while preserving adaptability.
