Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex mechanical equipment is employed for vertical beam tilt adjustment, horizontal steering, and horizontal beam width control, then beam control functionality is improved, but device complexity and cost increase
Solution Approach 1:
The antenna system is divided into multiple independent radiation units arranged in a matrix configuration, where each unit can be independently controlled. This segmentation allows complex beam control functionality to be achieved through coordinated operation of simpler individual units, rather than requiring a single complex mechanical adjustment system.
Solution Approach 2:
The patent employs adjustable and reconfigurable radiation units that can dynamically change their operational characteristics. The beam control is achieved through dynamic adjustment of phase and amplitude parameters of individual radiation units, replacing static mechanical beam tilt and steering mechanisms with dynamic electronic control.
2Adaptability or versatility
If complex mechanical equipment is employed for beam control, then beam control functionality is improved, but reliability decreases due to potential malfunctions
Solution Approach 1:
The patent replaces mechanical beam adjustment mechanisms with electronic phase and amplitude control systems. Instead of using mechanical motors and linkages to physically tilt or steer the antenna beam, the system uses electronic signal processing to control the phase and amplitude of signals fed to each radiation unit, achieving beam control without moving parts and thereby improving reliability.
3Adaptability or versatility
If complex mechanical equipment is employed for beam control, then beam control functionality is improved, but manufacturing cost increases
Solution Approach 1:
The radiation units are designed as universal, standardized components that can perform multiple functions through electronic reconfiguration. Each radiation unit can contribute to different beam directions, tilt angles, and beam widths by adjusting its phase and amplitude parameters, eliminating the need for separate mechanical mechanisms for each control function and reducing manufacturing complexity and cost.

AI summary
The present invention relates to a variable beam control antenna for a mobile communication system, the antenna comprising: a radome formed on the front surface at which a signal is emitted; multiple emitters vertically arranged in at least one row; a frame portion for supporting the radome and the multiple emitters; and a direction-changing module which rotates each of the multiple emitters vertically and horizontally with respect to a reference point in order to change the emission direction of the multiple emitters.
