Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive adhesives or solder are used to mitigate leakage through joints in two-piece waveguides, then leakage is reduced, but device complexity and cost increase
Solution Approach 1:
The waveguide is divided into two separate pieces that can be manufactured independently using injection molding, then assembled together. The segmentation is designed so that the joint between pieces does not require complex mitigation measures, as the orthogonal configuration naturally minimizes leakage paths.
Solution Approach 2:
The waveguide pieces are configured with orthogonal extensions where the radiator portion extends in one direction perpendicular to the separation plane, and the input portion extends in the opposite direction. This dimensional arrangement creates natural leakage barriers at the joint interface without requiring additional conductive materials.
2Reliability
If conductive adhesives or solder are used to mitigate leakage through joints, then leakage is reduced, but manufacturing cost increases
Solution Approach 1:
The waveguide is divided into two separate pieces that can be manufactured independently using injection molding, then assembled together. The segmentation is designed so that the joint between pieces does not require complex mitigation measures, as the orthogonal configuration naturally minimizes leakage paths.
Solution Approach 2:
The design eliminates the need for expensive conductive adhesives or solder by using the geometric configuration itself to prevent leakage. The orthogonal extensions create natural barriers that are sufficient for the application, removing the need for additional costly materials.
3Device complexity
If symmetrical two-piece design is used without solder or conductive adhesives, then assembly is simplified and cost is reduced, but leakage mitigation becomes challenging
Solution Approach 1:
The waveguide pieces are configured with orthogonal extensions where the radiator portion extends in one direction perpendicular to the separation plane, and the input portion extends in the opposite direction. This dimensional arrangement creates natural leakage barriers at the joint interface without requiring additional conductive materials.
Solution Approach 2:
While the overall design is symmetrical, the joint interface utilizes an orthogonal configuration where the extensions meet at right angles. This asymmetric angular relationship at the joint creates effective leakage barriers while maintaining the simplicity of assembly.

AI summary
A symmetrical two-piece waveguide is described herein. The waveguide comprises an upper structure that forms a first symmetrical portion of at least one channel that defines an energy path between an input portion and a radiator portion of the channel. The waveguide further comprises a lower structure that forms a second symmetrical portion of the channel that is symmetrical to the first symmetrical portion about a separation plane when the upper and lower structures are mated. The upper structure further forms the radiator portion that extends orthogonally from an upper surface of the first symmetrical portion opposite the separation plane. The lower structure further forms the input portion that extends orthogonally from a lower surface of the second symmetrical portion opposite the separation plane. By using symmetry, the disclosed waveguide leverages the benefits of a two-piece design while enabling near-lossless channeling of energy without conductive bonding.
