Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional advertisement signals are used in wireless communication, then device discovery and connection can be established, but coverage performance and anti-interference capability are insufficient
Solution Approach 1:
The patent changes the modulation parameter from conventional schemes to Phase-Shift Keying (PSK) modulation with polar code encoding. This parameter change improves the signal's resistance to interference and noise, directly addressing the technical contradiction by enhancing reliability through modified signal characteristics rather than changing the fundamental advertisement mechanism.
Solution Approach 2:
The patent substitutes conventional advertisement signal modulation with PSK modulation combined with polar code encoding. This substitution replaces the weaker conventional approach with a more robust mathematical encoding scheme that provides superior anti-interference capability while maintaining the advertisement function.
2Measurement precision
If advertisement signals are transmitted in noisy environments, then device communication can occur, but receiver sensitivity is insufficient
Solution Approach 1:
The patent modifies the signal parameter by implementing PSK modulation with polar code encoding, which fundamentally changes how the advertisement signal is structured and transmitted. This parameter modification enables the receiver to achieve higher sensitivity by exploiting the mathematical properties of polar codes that facilitate more accurate signal detection in noisy conditions.
Solution Approach 2:
The patent incorporates a feedback mechanism where the receiver uses the structured PSK-modulated signal with polar codes to improve detection accuracy. The encoded structure provides inherent feedback capabilities that allow the receiver to better distinguish the signal from noise, thereby improving receiver sensitivity in low signal-to-noise ratio environments.
