Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wireless communication is used for data transfer between rotating and stationary assemblies, then device complexity and cost are reduced, but data reliability and throughput stability deteriorate due to signal loss and electromagnetic interference
Solution Approach 1:
A deterministic positioning system acts as an intermediary between the rotating and stationary assemblies, providing precise real-time position information that enables the communication system to adapt to rotational motion and maintain reliable data transfer despite the challenging wireless environment
Solution Approach 2:
The communication system dynamically adjusts its parameters based on real-time rotational position data, allowing the transceivers to optimize signal transmission and reception as the rotating assembly moves through different angular positions, thereby maintaining reliability without increasing overall system complexity
2Productivity
If high bandwidth transmission is used to transfer scan data, then data throughput is improved, but signal corruption and data loss increase due to electromagnetic interference and relative motion
Solution Approach 1:
The deterministic positioning system provides continuous feedback on the rotational position to the communication system, enabling real-time adjustment of transmission parameters to maintain high throughput while compensating for electromagnetic interference and relative motion effects
Solution Approach 2:
Beamforming parameters are pre-calculated and stored for different rotational positions, allowing the system to quickly switch to appropriate parameters as the rotating assembly moves, thereby maintaining high data throughput without signal corruption
3Ease of manufacture
If conventional wireless transceivers are used without specialized shielding, then cost is reduced, but electromagnetic interference causes latency and throughput fluctuations
Solution Approach 1:
The system dynamically adapts communication parameters based on real-time rotational position feedback, allowing conventional transceivers to operate effectively without expensive specialized shielding by compensating for electromagnetic interference through software-based adjustments
