Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio wave reflection devices face challenges in achieving high reflection intensity, especially when the angle of incidence is large, and adjusting the reflector orientation to maximize reception levels is impractical due to the complexity of adjusting multiple parameters in three-dimensional space.
Innovation Solution
A radio wave reflection device with a joint unit allowing independent adjustment of the reflector's azimuth and elevation angles, utilizing two reflectors tilted at 45 degrees, and incorporating angle scales and scopes for precise alignment, enables effective reflection of radio waves around obstacles between antennas.

1Device complexity
If one reflector is used to relay radio waves, then the device structure is simple, but it is difficult to achieve high reflection intensity when the angle of incidence is large
Solution Approach 1:
The single reflector is divided into two separate reflectors (first reflector and second reflector). Each reflector handles a portion of the radio wave reflection process, allowing independent optimization of each reflector's orientation and angle to achieve high reflection intensity even at large angles of incidence.
Solution Approach 2:
The patent introduces a second reflector to create a multi-stage reflection system. This adds a dimensional aspect to the reflection process, where radio waves undergo sequential reflection from two different surfaces, enabling better control over the final reflection intensity and direction.
2Reliability
If multiple parameters (orientations of first antenna, reflector, and second antenna) are adjusted to maximize reception level, then the reception quality improves, but the adjustment process becomes practically impossible by trial and error
Solution Approach 1:
Orientation scales are pre-installed on the first antenna, second antenna, and reflector to indicate their respective orientations. This preliminary marking system allows operators to directly read and adjust orientations without complex trial-and-error procedures, making the adjustment process practical and systematic.
Solution Approach 2:
The orientation scales provide immediate visual feedback on the current orientation of each component. By comparing the scale readings with the desired orientation values, operators can systematically adjust the three parameters (first antenna orientation, reflector orientation, second antenna orientation) to achieve maximum reception level.

AI summary
A mounting unit (210) securely mounts a radio wave reflection device (200) on a stable installation place such as a pole (20). A reflector unit (300) holds two reflectors (350, 360) at a tilt angle of 45°, allowing the two reflectors (350, 360) to be coaxial and rotatable independently of each other. A joint unit (220) connects the reflector unit (300) and the mounting unit (210). The joint unit (220) has rotational freedom along two axes (AZ axis and EL axis) orthogonal to each other. A radio wave reflecting device that relays, by reflection, radio communications between a first antenna device and a second antenna device distant from each other is thereby provided.
