Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple antennas are used to improve antenna gain, then antenna gain is improved, but device complexity increases
Solution Approach 1:
A lens is introduced as an intermediary component between the antenna and the electromagnetic field. The lens focuses and directs electromagnetic energy to achieve improved antenna gain and directivity without requiring multiple antennas, thereby avoiding increased system complexity while still achieving the desired performance improvement
2Power
If directional antennas are used to concentrate electromagnetic energy, then gain in a specific direction is improved, but adaptability deteriorates
Solution Approach 1:
The lens design enables dynamic control of electromagnetic energy distribution. By adjusting the lens configuration or positioning, the system can optimize performance for different directions or maintain omnidirectional coverage as needed, providing adaptability while still achieving concentrated energy delivery when required
3Power
If lens is used to focus electromagnetic energy omnidirectionally, then antenna gain and directivity are improved, but manufacturing precision requirements increase
Solution Approach 1:
The lens is divided into multiple discrete elements or zones, each contributing to the overall omnidirectional focusing function. This segmentation allows for more tolerant manufacturing of individual elements while achieving the cumulative effect of precise omnidirectional energy concentration, reducing the overall manufacturing precision requirements
