Engineering Contradiction Analysis
1Productivity
If additional material resources are allocated to enhance data transmission capacity, then data throughput is improved, but material costs increase
Solution Approach 1:
The patent combines multiple data streams from different sensors into a single coded packet using network coding techniques. This merging approach allows multiple data streams to share the same transmission channel, thereby improving data throughput without requiring additional transmission materials or infrastructure.
Solution Approach 2:
The transmission medium is made universal by enabling it to carry multiple data streams simultaneously through coding. The same physical channel can transmit data from multiple sensors, making the transmission system multi-functional and eliminating the need for separate dedicated channels for each sensor, thus reducing material costs.
2Productivity
If data transmission capacity is increased to handle high volume sensor data, then data throughput is improved, but expenditure of time increases
Solution Approach 1:
By merging multiple data streams into coded packets, the system reduces the total number of transmission operations required. Instead of transmitting each sensor's data separately, multiple streams are combined and transmitted together, which decreases transmission time and prevents data from becoming outdated.
3Reliability
If multiple separate transmission channels are used for each sensor data stream, then data processing reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple data streams into coded packets that can be transmitted through a single channel. The receiving device reconstructs the original data streams from the coded packets, maintaining data processing reliability while significantly reducing device complexity compared to having separate channels for each sensor.
