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 time slots to different transceiver devices. Each device transmits only during its designated time slot, which divides the shared medium into separate transmission segments. This prevents signal collisions while maintaining extended network coverage through multiple distributed transceivers.
Solution Approach 2:
The system implements periodic transmission cycles where each transceiver device is assigned specific time slots for transmission. This periodic scheduling ensures that devices transmit in an organized sequence rather than simultaneously, reducing signal interference while preserving the benefits of multiple transceivers for extended coverage.
2Productivity
If multiple transceiver devices operate concurrently to increase network capacity, then the number of connected devices is improved, but signal collisions cause communication failures
Solution Approach 1:
The system performs preliminary channel assignment and time slot allocation before actual data transmission begins. Each transceiver device is pre-configured with specific transmission time slots and frequency channels, ensuring that concurrent operations do not result in signal collisions. This preliminary organization maintains both high network capacity and reliable communication.
Solution Approach 2:
The system incorporates feedback mechanisms where transceiver devices monitor the communication channel for signal quality and transmission success. Based on this feedback, devices can adjust their transmission timing and power levels to optimize performance, maintaining reliable communication while utilizing multiple devices for increased network throughput.
