Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If Bluetooth transmission is used, then transmission speed and real-time communication are improved, but transmission distance is limited and obstructed by obstacles
Solution Approach 1:
The patent combines Bluetooth and WIFI transmission channels into a unified communication system. The system establishes both channels simultaneously and selects the appropriate one based on transmission distance and obstacles, merging the advantages of both technologies to achieve both high speed and long distance transmission capabilities.
Solution Approach 2:
The patent implements dynamic switching between Bluetooth and WIFI channels based on real-time detection of transmission distance and obstacles. The system dynamically adjusts the transmission channel selection to optimize performance, transitioning from Bluetooth for close-range high-speed communication to WIFI for long-range transmission.
2Length of moving object
If WIFI transmission is used, then transmission distance is extended, but transmission stability deteriorates
Solution Approach 1:
The patent merges WIFI and Bluetooth channels into a complementary transmission system. WIFI provides long-distance coverage while Bluetooth ensures stable communication for close-range devices, and the system uses obstacle detection to select the most reliable channel, thereby achieving both extended distance and maintained stability.
Solution Approach 2:
The patent employs real-time feedback mechanisms to detect transmission distance and obstacles, using this information to dynamically select the optimal transmission channel. The system continuously monitors communication quality and adjusts channel selection to maintain transmission stability while extending reach.
3Device complexity
If a single wireless communication channel is used, then device complexity is reduced, but communication quality and link reliability deteriorate
Solution Approach 1:
The patent segments the transmission system into two distinct channels: Bluetooth for close-range high-speed communication and WIFI for long-range transmission. Each channel is optimized for specific use cases, and the system uses simple distance-based selection logic to manage complexity while achieving high communication quality through specialized channel usage.
