Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the detection device is integrated into a carrying device coupled to the head area, then the mobility and flexibility of the system is improved, but the alignment precision and positioning accuracy deteriorates
Solution Approach 1:
The system transitions from a static, permanently installed configuration to a dynamic, mobile configuration by coupling the detection device to a carrying device worn on the head. This allows the system to adapt to different measurement locations and orientations while maintaining functional precision through real-time data processing and visualization.
Solution Approach 2:
The carrying device acts as an intermediary between the user and the detection device, providing a stable platform that moves with the user's head while maintaining the relative positioning of the detection device. This intermediary structure enables mobility while preserving the functional relationship between the detection device and the acoustic field.
2Measurement precision
If the detection device is permanently installed in a test environment, then the measurement precision is improved, but the ease of operation and adaptability deteriorates
Solution Approach 1:
The system is designed to function both as a permanently installed measurement system and as a mobile handheld system. The detection device can be coupled to a carrying device for mobile operation or positioned in fixed locations for stationary measurement, providing universal applicability across different operational requirements.
Solution Approach 2:
The system allows dynamic switching between stationary and mobile operational modes. The detection device can be permanently installed for precision measurements or coupled to a carrying device for mobile applications, enabling the system to adapt to different operational needs while maintaining measurement capability.
3Measurement precision
If the entire system is reoriented for precise positioning, then the measurement precision is improved, but the device complexity and time consumption increase
Solution Approach 1:
The system extracts the detection device from the complex, permanently installed infrastructure and places it on a simple carrying device. This separation allows the detection device to be positioned and oriented independently without requiring complex system-wide realignment, simplifying the positioning process while maintaining measurement precision.
Solution Approach 2:
The system enables dynamic positioning where the detection device can be quickly oriented and positioned by simply moving the carrying device on the user's head, eliminating the need for complex, time-consuming system realignment procedures required by traditional permanently installed systems.
