Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In light fixtures with wireless control, the internal structure often obstructs the effective reception of RF signals by the antenna, limiting the accessibility and efficiency of wireless control signals.
Innovation Solution
The design includes a housing with a first PCB for power control and a second PCB with an antenna that converts RF signals, where the second PCB is operatively interconnected and projects outward from the first PCB to optimize RF signal reception, allowing the antenna to be located outside the housing for unobstructed signal reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the PCB and housing structure are designed to contain all components, then the device structure is compact and integrated, but the RF signal reception is obstructed by the housing and internal structure
Solution Approach 1:
The PCB is divided into two separate sections: a first PCB section containing power control circuitry and a second PCB section containing the antenna and RF signal conversion circuitry. This segmentation allows the antenna to be positioned separately from the housing structure that would otherwise obstruct RF signals, while still maintaining overall device integration.
Solution Approach 2:
The second PCB section is oriented to project outward from the first PCB section in a direction that optimizes RF signal reception. This dimensional arrangement positions the antenna in a location where it can receive RF signals effectively, avoiding obstruction by the housing and other internal components.
2Volume of moving object
If the antenna is positioned inside the housing for compact integration, then the device structure is compact, but the antenna access for RF signals is obstructed
Solution Approach 1:
The separation of the antenna-containing second PCB section from the main housing structure allows the antenna to be positioned in a location that is both integrated into the device and accessible to external RF signals. The second PCB section can project outward through apertures in the housing or be positioned in a manner that maintains compactness while ensuring unobstructed signal reception.

AI summary
A light fixture may have a housing containing a lighting element and any number of PCBs. A first PCB section may have circuitry that controls the lighting element. A second PCB section may have an antenna and circuitry that converts RF signals into control signal input to the first PCB section. The second PCB section may be operatively interconnected with the first PCB section, and may be contained in the housing in an orientation projecting from the first PCB section.
