Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive adhesives or solder are used to mitigate leakage in two-piece waveguides, then leakage is reduced, but device complexity and manufacturing cost increase
Solution Approach 1:
The waveguide structures employ asymmetrical design where the first and second waveguide structures are configured to be asymmetrical with respect to each other at the interface, creating a capacitive effect that blocks leakage without requiring conductive adhesives or solder
Solution Approach 2:
The patent changes the geometric parameters of the waveguide structures at the interface to create specific capacitive effects. By adjusting the asymmetry and dimensional parameters of the waveguide structures, the design achieves leakage mitigation through electromagnetic field manipulation rather than physical sealing
2Reliability
If conductive adhesives or solder are used to mitigate leakage in two-piece waveguides, then leakage is reduced, but manufacturing cost increases
Solution Approach 1:
The asymmetrical configuration of the waveguide structures creates a capacitive effect that inherently blocks leakage, eliminating the need for expensive conductive adhesives or solder materials while maintaining manufacturing simplicity
Solution Approach 2:
The patent extracts and eliminates the need for conductive adhesives or solder from the waveguide assembly process by replacing them with a geometric design solution that achieves the same leakage mitigation function through capacitive effects
3Productivity
If traditional two-piece waveguide designs are used, then mass production is enabled, but leakage mitigation requires additional materials and processes
Solution Approach 1:
The asymmetrical waveguide structure design integrates leakage mitigation directly into the geometry of the mass-producible components, allowing standard manufacturing processes to produce the asymmetrical features without requiring additional assembly steps or materials

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.
