Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional radiation sources (neutrons, electrons) are used for diffraction and analysis, then measurement precision and analytical capability are improved, but device size and weight increase significantly, making the equipment immobile and suitable only for large laboratory premises
Solution Approach 1:
The device is divided into separate functional modules: a radiation source unit, a detection unit, and a robotic positioning system. Each module can be independently positioned and controlled, allowing the system to achieve precise measurements without requiring a single large, fixed installation. The robotic arms with controlled paths enable each segment to be moved to appropriate positions for diffraction measurements.
Solution Approach 2:
Traditional mechanical goniometers and fixed positioning mechanisms are replaced with a robotic system that uses controlled path movement. The robotic arms can position the radiation source and detector along predetermined trajectories, eliminating the need for large mechanical goniometer structures while maintaining the precision required for diffraction measurements.
2Measurement precision
If traditional mechanical goniometers are used for precise positioning, then measurement accuracy is improved, but device complexity and size increase, preventing easy deployment and transportation
Solution Approach 1:
Complex mechanical goniometers are replaced with a robotic positioning system that uses controlled path movement. The robotic arms follow predetermined trajectories to position the radiation source and detector, achieving the necessary angular precision for diffraction measurements without the mechanical complexity of traditional goniometers. This substitution reduces mechanical linkages, gears, and adjustment mechanisms.
Solution Approach 2:
The system transitions from static mechanical goniometer structures to dynamic robotic positioning. The robotic arms can move along controlled paths to achieve the required positioning accuracy, allowing the system to adapt to different measurement configurations without reconfiguring mechanical components. This dynamic approach simplifies the overall mechanical structure.
3Adaptability or versatility
If multiple radiation sources are used contemporaneously, then analytical versatility and complementary information are improved, but device complexity and control difficulty increase
Solution Approach 1:
The device is designed with multiple radiation sources (neutron, electron, X-ray) that can be used either simultaneously or interchangeably. Each source type provides complementary information for different analytical purposes, making the device universally applicable to various measurement requirements. The robotic positioning system and controlled path movement enable the device to accommodate different source configurations without requiring separate specialized equipment for each radiation type.
