Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracking systems face inefficiencies due to antenna polarization alignment issues, leading to attenuation and cross-polarization challenges in positioning signal transmission and reception between positioning devices and objects, which affect the accuracy and reliability of object positioning.
Innovation Solution
The system involves offsetting the polarization axes of antennas on positioning devices and objects by greater than thirty degrees from both parallel and perpendicular orientations, typically set at forty-five degrees, to minimize attenuation and cross-polarization effects, thereby optimizing communication and positioning accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the polarization axes of antennas are aligned parallel or perpendicular, then the antenna structure is simple and easy to manufacture, but signal attenuation and cross-polarization effects increase
Solution Approach 1:
The patent changes the polarization angle parameter from the conventional 0° (parallel) or 90° (perpendicular) alignment to a 45° offset configuration. This parameter modification reduces signal attenuation and cross-polarization effects while maintaining manufacturing feasibility, directly resolving the contradiction between signal loss and device complexity.
2Reliability
If the polarization axes are offset by greater than thirty degrees, then communication efficacy and positioning accuracy improve, but the antenna alignment complexity increases
Solution Approach 1:
The patent introduces asymmetric polarization axis alignment at 45° offset, breaking the symmetric parallel or perpendicular configuration. This asymmetric arrangement optimizes signal transmission reliability and positioning accuracy while the fixed angular specification keeps the implementation complexity manageable.
