Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional horizontally-polarized omni-directional antennas are used, then electromagnetic interference is reduced, but the antenna becomes expensive and difficult to install
Solution Approach 1:
The patent applies the copying principle by mimicking the size, shape, and appearance of conventional vertically-polarized antennas. The horizontally-polarized omni-directional antenna is designed to have the same external form factor as standard vertical antennas, making it visually indistinguishable and interchangeable in appearance. This allows the antenna to reduce electromagnetic interference through horizontal polarization while maintaining the ease of installation and familiar appearance of conventional vertical antenna designs.
2Object-affected harmful factors
If conventional horizontally-polarized omni-directional antennas are used, then electromagnetic interference is reduced, but mechanical design issues arise especially in vehicle-mounted applications
Solution Approach 1:
The patent resolves mechanical reliability issues by copying the proven mechanical design of conventional vertically-polarized antennas. The supporting structure, mounting bracket, and overall mechanical architecture are designed to match standard vertical antenna configurations. This allows the antenna to achieve horizontal polarization for interference reduction while relying on the tested and reliable mechanical design of conventional vertical antennas, particularly for vehicle-mounted applications where mechanical robustness is critical.
3Object-affected harmful factors
If conventional horizontally-polarized omni-directional antennas are used, then electromagnetic interference is reduced, but the antenna becomes expensive
Solution Approach 1:
The patent reduces manufacturing cost by copying the production processes and component specifications of conventional vertically-polarized antennas. The tube dimensions, slot aperture specifications, supporting structure materials, and assembly procedures are designed to match industry-standard vertical antenna manufacturing. This enables manufacturers to produce horizontally-polarized omni-directional antennas using existing tooling, materials, and assembly lines, thereby avoiding the need for expensive new manufacturing infrastructure while still achieving interference reduction through horizontal polarization.
