Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If omnidirectional antennas are used for controlling flight of unmanned aerial vehicle, then the antenna can transmit or receive electromagnetic signals in all directions, but the gain is low and transmission distance is short
Solution Approach 1:
The antenna is divided into distinct functional segments: a radome for omnidirectional signal reception, a reflecting bottom housing for directional signal reflection, and an antenna module for signal generation. This segmentation allows the antenna to simultaneously achieve omnidirectional adaptability and enhanced directional transmission distance by reflecting signals toward the radome opening.
Solution Approach 2:
The patent introduces a spatial dimension by adding a reflecting bottom housing that redirects signals from the antenna module upward toward the radome. This creates a three-dimensional signal path where signals are transmitted both directly and via reflection, extending the effective transmission distance in the vertical dimension while maintaining omnidirectional coverage.
2Adaptability or versatility
If the antenna module radiates electromagnetic signal in all directions, then the signal coverage is comprehensive, but the signal intensity in any single direction is insufficient
Solution Approach 1:
The antenna structure implements local quality enhancement by concentrating signal intensity in specific regions. The reflecting bottom housing creates a localized high-intensity zone by reflecting signals toward the radome opening, while the radome itself maintains omnidirectional signal distribution. This allows the antenna to provide comprehensive coverage with enhanced intensity in the direction of the radome opening.
Solution Approach 2:
The reflecting bottom housing acts as an intermediary element that redirects electromagnetic signals from the antenna module toward the radome. This intermediary structure enhances signal intensity by concentrating reflected waves in the upward direction, thereby improving the overall signal strength without compromising the omnidirectional coverage capability of the radome.
