Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If zero-power devices are deployed with high density and large scale, then deployment cost is reduced, but data transmission performance deteriorates
Solution Approach 1:
The patent applies forward error correction encoding as a preliminary action to the data transmission process. The transmitting device encodes the data signal with FEC codes before transmission, enabling the receiving device to correct errors that occur during transmission. This preliminary encoding action ensures reliable data transmission even in high-density zero-power device deployments where transmission errors are more likely to occur.
2Device complexity
If no encoding is applied to transmitted signals, then device complexity is reduced, but transmission error rate increases
Solution Approach 1:
The patent changes the parameter of the transmitted signal by applying forward error correction encoding. This transforms the original data signal into an encoded signal with added redundancy bits. The encoding process modifies the signal parameters (adding check bits according to FEC codes) to enable error detection and correction at the receiving end, thereby improving transmission reliability while maintaining relatively simple device complexity.
