Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional rigid waveguides and transmission lines are used, then structural stability is maintained, but flexibility and adaptability to changing environments are lost
Solution Approach 1:
The patent employs flexible substrates and thin film conductive layers to create waveguides and transmission lines that can deform while maintaining electrical performance. The conductive structures are fabricated on flexible substrates using deposition techniques, enabling the entire assembly to bend and adapt to dynamic environments without compromising structural integrity or electrical functionality
Solution Approach 2:
The invention uses composite material structures combining flexible substrates with conductive layers (such as metal films or conductive polymers). This composite approach allows the waveguide to exhibit both mechanical flexibility for adaptability and sufficient structural stability to maintain electrical performance during deformation
2Adaptability or versatility
If deformable materials are used to achieve flexibility, then adaptability to dynamic environments is improved, but manufacturing precision and electrical performance consistency may deteriorate
Solution Approach 1:
The conductive structures are fabricated on flexible substrates before the substrates are deployed in dynamic environments. This preliminary fabrication ensures precise control over conductor geometry, width, and spacing while the substrate is in a stable, flat state, thereby maintaining manufacturing precision even though the final application involves deformation
Solution Approach 2:
The patent controls electrical performance parameters (such as characteristic impedance) by precisely controlling the geometry and material properties of the conductive structures during fabrication. By maintaining consistent physical parameters during manufacturing on flexible substrates, the invention ensures electrical performance consistency despite the flexible nature of the final product

AI summary
A conductive assembly may include a deformable substrate disposed around an axis, and a deformable conductor arranged on the deformable substrate. The substrate may be arranged to form a channel along the axis, and the deformable conductor may be arranged on the deformable substrate to form a waveguide. The deformable substrate, the first deformable conductor, and a second deformable conductor may be arranged to form a microstrip or a coaxial transmission line. A deformable transmission line may include a deformable substrate arranged in a substantially enclosed channel around an axis, a first deformable conductor arranged in a trace along the axis of the deformable substrate, and a second deformable conductor arranged on the deformable substrate to form a reference conductor for the first deformable conductor. A method of fabricating a deformable conductive assembly may include forming a deformable conductor on a deformable substrate, and disposing the deformable substrate around an axis.
