Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the UE device transmits longer messages to convey more information, then the information completeness is improved, but the transmission reliability deteriorates under poor channel conditions
Solution Approach 1:
The patent dynamically adjusts message length based on real-time channel conditions. The UE device determines channel quality indicators and adapts the message length parameter accordingly, transforming from static message transmission to dynamic adaptation. This resolves the contradiction by making message length flexible rather than fixed, allowing optimization between information completeness and transmission reliability based on current channel state.
Solution Approach 2:
The patent changes the message length parameter according to channel conditions. By modifying this key parameter dynamically, the system achieves better transmission reliability without permanently sacrificing information completeness. The parameter adjustment allows the same communication system to operate effectively under varying channel conditions.
2Reliability
If the UE device retransmits messages to improve delivery reliability, then the transmission reliability is improved, but the time delay increases
Solution Approach 1:
The patent performs preliminary action by adjusting message length before transmission based on predicted or current channel conditions. This preventive approach avoids the need for retransmission delays by ensuring the message is optimized for the current channel state from the outset, thus improving delivery reliability without incurring retransmission time penalties.
Solution Approach 2:
The patent enables the system to skip retransmission by transmitting an optimally sized message that is more likely to succeed on the first attempt. By rushing through with a well-prepared, condition-adapted message, the system avoids the time-consuming retransmission process while maintaining high delivery reliability.
3Adaptability or versatility
If the UE device increases processing functionality to handle complex communications, then the communication capability is improved, but the power consumption increases
Solution Approach 1:
The patent applies partial action by implementing only the necessary level of processing complexity required for the current channel conditions. Rather than always using maximum processing capability, the system adjusts its processing intensity to match the actual needs, reducing unnecessary power consumption while maintaining adequate communication capability.
Solution Approach 2:
The patent dynamically adjusts processing functionality based on channel conditions and message requirements. The UE device activates higher-level processing functions only when needed, rather than maintaining constant high-processing state. This dynamic adaptation reduces average power consumption while preserving communication capability when required.
