Solution Overview
Problem
The challenge is to develop a clamping apparatus for antennas that enhances installation freedom and workability in spatially restricted environments while maintaining a predetermined antenna direction, preventing arbitrary tilting and rotation.
Innovation Solution
The apparatus includes a rotation unit for horizontal adjustment, a tilting unit for vertical adjustment, and a rotation/vibration prevention unit with a motor, worm gear, and damping idle gears to secure the antenna direction, using a combination of spur and worm wheel gear teeth to prevent unwanted movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of antennas is increased to expand coverage and data transmission capacity, then channel capacity and coverage are improved, but device size and weight increase
Solution Approach 1:
The patent implements a nested antenna structure where multiple antennas are arranged in layers, with second antennas positioned behind first antennas. This nesting approach allows multiple antennas to occupy a compact spatial volume, increasing channel capacity without proportionally increasing the overall device footprint and weight.
Solution Approach 2:
The patent transitions from two-dimensional antenna arrangement to three-dimensional layered configuration. By stacking antennas in multiple layers along the depth dimension, the system achieves higher antenna density and channel capacity while maintaining a compact form factor that does not linearly scale with antenna count.
2Volume of moving object
If RF components are miniaturized to reduce size and weight, then installation space requirement is reduced, but heat dissipation becomes more difficult
Solution Approach 1:
The patent divides the antenna system into multiple independent antenna modules arranged in layers. Each module can be separately designed with its own heat dissipation path, allowing heat to be managed at the module level rather than requiring the entire compact structure to dissipate heat simultaneously, thus managing thermal load in miniaturized configurations.
3Adaptability or versatility
If antennas are installed on a single support pole in limited space, then installation freedom is improved, but adjustment of antenna direction becomes difficult
Solution Approach 1:
The patent incorporates rotatable and tiltable mechanisms that enable dynamic adjustment of antenna directions. The first and second antennas can be independently rotated and tilted to different angles, allowing operators to optimize signal coverage and transmission quality even when constrained to a single support pole installation location.
4Volume of moving object
If the antenna structure is made compact for dense installation, then spatial utilization is improved, but stability against arbitrary rotation is reduced
Solution Approach 1:
The patent employs locking mechanisms that secure the rotatable and tiltable components at predetermined positions. These locking structures are designed to maintain antenna orientation stability once adjusted, preventing arbitrary rotation or tilting due to external forces such as wind or vibration, while the compact overall structure remains space-efficient.

AI summary
The present invention relates to a clamping apparatus for an antenna, the clamping apparatus including a rotation unit configured to rotate an antenna in a horizontal direction, a tilting unit configured to rotate the antenna in a vertical direction, and a rotation/vibration prevention unit configured to adjust a direction of the antenna by rotating at least one of the rotation unit and the tilting unit and prevent the antenna from arbitrarily rotating after the direction of the antenna is adjusted, in which the rotation/vibration prevention unit includes a rotation motor, a worm gear configured to be rotated by the rotation motor, a shaft configured to define at least one rotation center, and a worm wheel gear installed on an outer peripheral surface of the shaft and configured to rotate at least one of the rotation unit and the tilting unit while being rotated by the worm gear, thereby easily adjusting the direction of the antenna by controlling the rotation motor and preventing the antenna with the adjusted direction from arbitrarily rotating.
