Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If antenna size is reduced, then device size is reduced, but radiation gain becomes insufficient
Solution Approach 1:
The patent implements a nested structure where multiple ring-shaped metal elements (first ring, second ring, third ring) are arranged concentrically around the antenna element. Each ring serves as a director element, with the rings nested within each other's spatial envelope, thereby enhancing radiation gain without proportionally increasing the overall antenna volume.
Solution Approach 2:
The patent transitions from a planar antenna design to a three-dimensional structure by introducing multiple ring-shaped director elements at different radial distances from the antenna element. This spatial arrangement in multiple dimensions enhances the radiation pattern and gain while maintaining a compact footprint suitable for contact lens integration.
2Reliability
If multiple ring-shaped metal structures are added, then radiation gain is improved, but device complexity increases
Solution Approach 1:
Each ring-shaped metal structure serves multiple functions: it acts as a director element for the antenna, provides structural support, and can be configured with specific geometries to control the radiation pattern. This multi-functionality reduces the need for separate components, thereby managing complexity while achieving enhanced radiation gain.
Solution Approach 2:
The ring-shaped metal structures can be designed with asymmetric geometries or non-uniform spacing to optimize radiation patterns for specific communication directions. This asymmetric design allows tailored performance without requiring complex active control mechanisms, balancing complexity and performance.
