Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a radiating antenna with greater transmit power is used to transmit signals to a wider range, then transmission quality is improved, but temperature increases due to heat generation
Solution Approach 1:
The patent divides a single high-power antenna into multiple low-power radiating antennas arranged in an array. Each antenna element operates at lower power individually, but collectively they achieve the required transmission quality through coherent combining. This segmentation resolves the contradiction by maintaining transmission quality while reducing temperature and heat generation at each antenna element.
Solution Approach 2:
The patent combines multiple low-power antenna elements into a unified phased array system that achieves high-gain transmission through constructive interference. By merging the signals from multiple low-power antennas with phase control, the system attains the transmission quality of a single high-power antenna without the associated heat generation and temperature issues.
2Temperature
If multiple radiating antennas with lower transmit power are used, then temperature is reduced, but wiring complexity increases
Solution Approach 1:
The patent replaces the traditional mechanical/electrical connection system (physical wiring from each antenna to the transmitter) with a wireless feeding mechanism. A feed antenna wirelessly transmits signals to each radiating antenna element, eliminating the need for complex physical wiring and connectors. This substitution resolves the contradiction by maintaining the low-power multi-antenna configuration while dramatically reducing wiring complexity.
Solution Approach 2:
The patent introduces a feed antenna as an intermediary element that wirelessly couples the transmitter to the multiple radiating antenna elements. This intermediary enables signal distribution to multiple antennas without requiring direct physical connections from the transmitter to each antenna element, thereby reducing wiring complexity while maintaining the temperature benefits of low-power operation.
3Reliability
If multiple radiating antennas are used to achieve power gain, then transmission quality is improved, but control complexity increases
Solution Approach 1:
The patent implements dynamic phase control of the signals fed to each antenna element through electronic phase shifters. The phase of each antenna element can be dynamically adjusted to achieve beam forming and steering, enabling coherent combining for improved transmission quality. This dynamic control resolves the contradiction by providing a systematic method to manage multiple antenna elements with relatively simple electronic control rather than complex mechanical or manual adjustment.
