Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional waveguide structures are used, then electromagnetic wave transmission is achieved, but weight and cost increase
Solution Approach 1:
The waveguide structure is divided into multiple sections with alternating conductive and insulating carriers. Conductive carriers (first and third) provide electromagnetic shielding and signal transmission, while insulating carriers (second and fourth) provide structural support and electrical isolation. This segmentation allows the waveguide to achieve effective electromagnetic wave transmission with reduced weight compared to fully conductive structures.
Solution Approach 2:
The waveguide employs a composite structure combining conductive materials (for electromagnetic wave guidance) and insulating materials (for mechanical support and electrical isolation). The alternating arrangement of conductive and insulating carriers creates a composite waveguide that optimizes both electromagnetic performance and weight characteristics.
2Loss of energy
If conventional waveguide structures are used, then electromagnetic wave transmission is achieved, but manufacturing cost increases
Solution Approach 1:
The waveguide is constructed from modular repeating units of alternating conductive and insulating carriers, each with grooves accommodating conductive bodies. This standardized segmentation enables efficient manufacturing through repetitive production processes and simplifies assembly, thereby reducing overall manufacturing cost while maintaining low insertion loss performance.
Solution Approach 2:
The insulating carriers provide structural support and electrical isolation at lower cost compared to using entirely conductive materials. By strategically placing inexpensive insulating carriers between conductive carriers, the design achieves the required electromagnetic performance with reduced material costs.
3Weight of moving object
If conductive bodies are placed in grooves of insulating carriers, then weight is reduced, but assembly precision requirements increase
Solution Approach 1:
The grooves in the insulating carriers are strategically positioned and dimensioned to precisely accommodate the conductive bodies at critical locations. This local precision in groove design ensures proper alignment and electrical connection while allowing the overall structure to maintain reduced weight through the use of insulating materials.
