Flush-Mounted RF Transmitter Antenna for Building Signal Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless systems for activating appliances often face interference from building materials like stucco, steel, or aluminum siding, leading to signal degradation and unsightly aesthetics due to protruding transmitter units.
Innovation Solution
The wireless transmitter apparatus positions its antenna within an opening in a building's structural element, such as a drilled hole, to minimize interference and absorption, ensuring signal quality and aesthetic appeal by mounting the transmitter flush to the wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the wireless transmitter is mounted on the exterior wall surface, then the installation is simple and aesthetic, but the building materials (stucco, steel, aluminum siding) interfere with and absorb the wireless signals
Solution Approach 1:
The patent transitions the antenna from a surface-mounted configuration to a three-dimensional position by extending it through the wall opening. This dimensional change allows the antenna to protrude beyond the wall surface, positioning it in a spatial location that avoids signal interference from building materials while maintaining aesthetic appearance when retracted.
Solution Approach 2:
The patent introduces a wall opening as an intermediary structure that facilitates signal transmission. The opening acts as a pathway that allows RF signals to pass through the building structure without being absorbed or interfered with by stucco, steel, or aluminum siding materials.
2Reliability
If the antenna extends through the wall opening, then signal transmission is improved without interference, but the aesthetic appearance is compromised due to protrusion
Solution Approach 1:
The patent applies a retractable mechanism to the antenna, making it dynamic rather than fixed. The antenna can extend through the wall opening when signal transmission is needed and retract into the wall cavity when not in use, thereby adapting its position to balance both aesthetic appearance and functional performance.
Solution Approach 2:
The patent divides the transmitter system into separate functional components: the main housing that mounts flush to the wall for aesthetic purposes, and the antenna that can independently extend and retract. This segmentation allows each component to optimize for its primary function while minimizing compromise of the other.
3Reliability
If the transmitter unit protrudes from the wall, then the antenna can transmit signals without interference, but the aesthetic appeal is reduced
Solution Approach 1:
The retractable antenna mechanism allows the system to dynamically adjust its configuration based on operational needs. When installed, the antenna retracts to maintain aesthetic appeal, and only extends when signal transmission is required, thus resolving the conflict between appearance and function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for effective, interference-free transmission of RF signals to appliances, enhancing user satisfaction with improved aesthetics and ease of implementation.
Implementation Method 1
When a wireless actuator is actuated, a radio frequency (RF) signal is formed and then transmitted via an antenna to the appliance
Implementation Method 2
The antenna is disposed within an opening in the structural element of the building and is of dimensions so as to extend at least partially through the opening. The antenna transmits the signal to the appliance without significant interference or absorption from the structural element of the building
