Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional millimeter-wave receiving devices are used, then high detection capability is achieved, but high cost and complicated construction occur
Solution Approach 1:
The receiving device is divided into independent modular units, each comprising a radiometer and its dedicated positioning assembly. This segmentation allows each module to be optimized independently while maintaining overall system performance, reducing the complexity of the entire system.
Solution Approach 2:
The patent employs simplified positioning members with basic geometric features (saw-shaped steps, positioning surfaces) instead of complex mechanical positioning systems. These simple structures achieve adequate positioning precision at significantly lower cost and complexity.
2Device complexity
If radiometers are positioned without precise positioning assembly, then device simplicity is maintained, but thermal drift and electrical-magnetic interference occur
Solution Approach 1:
The positioning assembly acts as an intermediary structure between the radiometer and the support framework. It provides both mechanical support and electromagnetic shielding, isolating the radiometer from external interference while enabling precise positioning through saw-shaped steps and positioning surfaces.
Solution Approach 2:
The positioning assembly is designed with built-in compensation features that preemptively counteract thermal drift and electromagnetic interference. The structured design with radiating fins and shielding walls prevents these issues before they affect measurement accuracy.
3Ease of manufacture
If radiometers are not precisely oriented, then ease of installation is improved, but radiation path alignment accuracy deteriorates
Solution Approach 1:
The positioning assembly incorporates pre-formed saw-shaped steps and positioning surfaces that establish the correct radiation path alignment before the radiometer is installed. This preliminary structuring ensures accurate orientation is achieved automatically during installation without requiring complex adjustment procedures.
