Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple transceiver devices are deployed to increase transmission and reception range, then the network coverage is improved, but signal collisions and interference increase
Solution Approach 1:
The system segments the communication channels by assigning different frequency channels to different transceiver modules. The host device allocates specific frequency channels to each module, allowing simultaneous operations on multiple channels without signal collision. This frequency division segmentation resolves the interference problem while maintaining expanded network coverage.
Solution Approach 2:
The host device acts as an intermediary that coordinates communication between multiple transceiver modules and external devices. It manages frequency channel allocation, assigns modules to specific channels, and handles signal routing, thereby preventing signal collisions while enabling extended network coverage through multiple modules.
2Productivity
If multiple transceiver modules operate concurrently to increase connection capacity, then the number of connections is improved, but signal collisions occur
Solution Approach 1:
The system divides the communication spectrum into multiple frequency channels and assigns each transceiver module to a specific channel. This segmentation allows concurrent operations of multiple modules without signal collision, simultaneously improving connection throughput and maintaining communication reliability through dedicated channel allocation.
Solution Approach 2:
The system changes the frequency parameter of operation for each transceiver module. By operating modules on different frequency channels rather than the same frequency, the system enables concurrent high-capacity connections while preventing signal collisions, thus improving both throughput and reliability.
3Adaptability or versatility
If a single master transceiver is used to receive signals from multiple devices, then device connectivity is improved, but signal collisions cause interference
Solution Approach 1:
Instead of a single master transceiver handling all connections, the system segments the reception function across multiple transceiver modules, each operating on different frequency channels. This allows the host to maintain versatile device connectivity while avoiding signal collisions through frequency division.
Solution Approach 2:
The host device achieves universal connectivity by coordinating multiple transceiver modules that can simultaneously communicate with different external devices on different channels. This multi-functional approach enhances device connectivity versatility while preventing signal interference through channel allocation.
