Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If code block repetitions are used to support longer range communication, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments the data transmission into multiple code blocks that can be independently repeated and transmitted. Each code block can be separately decoded, allowing the system to achieve reliable long-range communication by transmitting multiple segments rather than requiring the entire data set to be transmitted perfectly in one go.
Solution Approach 2:
The patent applies pre-forward error correction padding before code block repetition to prepare the data for reliable transmission. This preliminary error correction preparation ensures that even if some repeated code blocks are corrupted during long-range transmission, the original data can still be recovered.
2Reliability
If pre-forward error correction padding is calculated before code block repetitions, then communication reliability is improved, but processing time increases
Solution Approach 1:
The patent performs pre-forward error correction padding before code block repetition as a preliminary action to ensure data integrity. By preparing the error correction codes in advance, the system ensures that even if transmission errors occur during long-range communication, the data can be reliably recovered without requiring complex post-transmission processing.
3Adaptability or versatility
If extended long-range packets are used to support devices with varied transmit capabilities, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal packet structure that can accommodate devices with different transmit capabilities. The extended long-range packet format with code block repetitions and pre-FEC padding can be used by any device regardless of its specific transmit power or range capabilities, making the system universally applicable across diverse device types.
Solution Approach 2:
The patent enables dynamic adaptation of transmission parameters including the number of code block repetitions and pre-FEC padding levels based on the specific transmit capabilities and channel conditions. This dynamic configuration allows the system to optimize performance for each device while using a unified packet structure.
4Reliability
If multiple code block repetitions are transmitted, then communication reliability is improved, but loss of time increases
Solution Approach 1:
The patent segments data into code blocks that can be repeated and transmitted in parallel or sequentially. By dividing the data into manageable segments, the system can transmit multiple repetitions without requiring the entire data set to be transmitted multiple times, thereby reducing overall transmission time while maintaining reliability.
