Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a dielectric lens is used to control electromagnetic waves, then radio wave refraction is achieved, but the device becomes bulky and complex
Solution Approach 1:
The patent divides the radio wave control function into multiple discrete resonator elements arranged in an array. Each resonator element acts as an independent unit that can be individually designed and positioned, replacing the monolithic dielectric lens structure with a segmented, planar configuration that achieves the same wave control function with reduced thickness and complexity.
Solution Approach 2:
The patent transitions from a three-dimensional dielectric lens structure to a two-dimensional resonator array configuration. By arranging resonators in a planar array with specific spacing and orientations, the patent achieves volume-to-surface transformation, maintaining wave control functionality while significantly reducing the device thickness and eliminating the need for bulky dielectric materials.
2Adaptability or versatility
If resonator elements are arranged to control radio waves, then phase change capability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent assigns different orientations and configurations to resonator elements at different positions within the array. Each resonator is locally optimized with specific spacing and angular orientations relative to its neighbors, allowing the overall system to achieve wide phase change capability while each individual element maintains simple, manufacturable geometry that tolerates standard manufacturing variations.

AI summary
A radio wave control plate includes a plurality of unit structures arrayed in a first plane direction, and a reference conductor serving as a reference potential of the plurality of unit structures. Each of the plurality of unit structures includes a first resonant structure and a second resonant structure that are rotationally symmetric in the first plane direction, each of the first resonant structure and the second resonant structure including a first resonator extending in the first plane direction and second resonators formed on the same plane as the first resonator and electromagnetically connected to the reference conductor. The first resonant structure and the second resonant structure are spaced apart from each other in a first direction such that the first resonator and the second resonators of the first resonant structure correspondingly face the first resonator and the second resonators of the second resonant structure.
