Illuminated Antenna Cover for Ceiling Wireless Control Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load control devices in buildings face a challenge in minimizing device size while maintaining excellent antenna gain, as large antennas for effective communication are unsightly and distracting, and hiding them compromises communication range.
Innovation Solution
A wireless control device with a protruding antenna structure illuminated by visible light, featuring a light-transmissive cover that extends from the device, allowing for both aesthetic integration and functional visibility, enhancing communication reliability and simplifying troubleshooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the antenna size is reduced to minimize device appearance, then the aesthetic appearance is improved, but the antenna gain deteriorates
Solution Approach 1:
The patent extends the antenna in the vertical dimension by allowing it to protrude from the ceiling surface. This dimensional change enables the antenna to achieve sufficient length for good gain while maintaining a compact horizontal footprint that minimizes visual distraction in the ceiling plane.
2Reliability
If the antenna size is increased to improve antenna gain, then the communication range is improved, but the device becomes more distracting to users
Solution Approach 1:
The antenna is oriented vertically protruding from the ceiling, utilizing the third dimension (height) rather than expanding horizontally. This allows the antenna to achieve the necessary length for good communication range while presenting a minimal visual profile when viewed from typical user eye level in the room.
Solution Approach 2:
The antenna structure incorporates a light-transmissive cover that can be illuminated to indicate operational status. This local functional enhancement provides visual feedback to users about device status without requiring the antenna itself to be visually prominent or distracting.
3Shape
If the antenna is hidden behind the ceiling tile to improve appearance, then the aesthetic appearance is improved, but the communication range deteriorates
Solution Approach 1:
Rather than hiding the antenna completely behind the ceiling tile, the patent allows controlled protrusion in the vertical dimension. This partial exposure maintains aesthetic appearance by keeping the antenna out of the horizontal ceiling plane while providing sufficient exposed length for effective communication.
4Shape
If the device size is minimized to reduce visual distraction, then the aesthetic appearance is improved, but the antenna gain deteriorates
Solution Approach 1:
The antenna is configured to protrude vertically from the ceiling surface, utilizing the height dimension to achieve sufficient antenna length for good gain. This vertical orientation allows the device body to remain compact and minimally distracting in the horizontal ceiling plane while the antenna extends downward to provide necessary communication performance.

AI summary
A wireless control device, such as a system controller for a load control system, may comprise a light-transmissive cover for an antenna that may be illuminated to provide feedback to a user of the load control system. The light-transmissive cover may receive light energy from a light-generating circuit to provide a visible display of the light energy. The wireless control device may be mounted to, for example, a ceiling, and the light-transmissive cover may extend from the wireless control device (e.g., down from the ceiling). The light-transmissive cover may be viewed by a user at large viewing angles and at a distance away from the wireless control device, which may simplify and improve reliability of commissioning of the load control system as well as speed up troubleshooting of the load control system after commissioning is completed.
