Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio signals are used to detect peripheral device position, then positioning capability is improved, but measurement precision deteriorates due to erroneous detection
Solution Approach 1:
The patent introduces an intermediary processing mechanism between audio signal reception and position determination. The processor analyzes multiple audio signals from different speakers and uses time difference calculations as an intermediary step to derive position information, thereby filtering out erroneous detections and improving measurement precision while maintaining positioning capability
Solution Approach 2:
The system implements feedback by continuously monitoring audio signal reception times and comparing calculated positions with expected positions. When discrepancies are detected, the system adjusts its detection parameters or requests re-detection, thereby eliminating erroneous detections and improving measurement accuracy
2Measurement precision
If multiple speakers output distinct audio signals for positioning, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The patent divides the audio output function into multiple independent speakers that emit distinct audio signals. Each speaker acts as an independent element in the positioning system, allowing the processor to calculate position based on time differences from multiple sources. This segmentation improves positioning accuracy while keeping each speaker relatively simple
Solution Approach 2:
The processor performs multiple functions: it manages audio signal output coordination, calculates time differences, determines peripheral device position, and provides positioning information to the user. By making the processor multi-functional, the patent avoids adding separate dedicated hardware for each function, thereby improving positioning accuracy without proportionally increasing device complexity
