Solution Overview
Problem
Conventional light fixtures with integrated sensors often have aesthetically unappealing antenna components that can cause signal interference, and there is a need for efficient energy conservation in lighting systems through improved sensor integration.
Innovation Solution
The integration of an antenna assembly with a sensor module in light fixtures, where the antenna is disposed on an exposed component with a substantially unobstructed line of sight, allowing for efficient signal transmission and reception while being aesthetically integrated into the fixture's design, and utilizing various communication technologies such as RFID, WiFi, or Bluetooth for occupancy detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If antenna components are integrated into light fixtures, then wireless communication functionality is achieved, but aesthetic appearance deteriorates
Solution Approach 1:
The patent combines the antenna assembly with the sensor module into a single integrated unit. The antenna elements are positioned within the sensor module housing, merging two functional components (antenna and sensor) into one unified structure that serves both wireless communication and occupancy detection purposes while maintaining aesthetic appearance.
2Adaptability or versatility
If antenna components are integrated into light fixtures, then wireless communication functionality is achieved, but signal interference increases
Solution Approach 1:
The patent positions the antenna assembly on an exposed component of the light fixture with substantially unobstructed line of sight to the ambient environment. This local positioning strategy ensures that the antenna elements are located in a specific zone (exposed external surface) that provides optimal signal transmission and reception while minimizing interference from the fixture's internal metal components.
3Reliability
If antenna is disposed on exposed component with unobstructed line of sight, then signal transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The antenna assembly is integrated with the sensor module, combining wireless communication functionality with occupancy sensing capabilities in a single unit. This merger reduces the number of separate components and simplifies the overall device structure while achieving unobstructed signal transmission through strategic positioning on the light fixture's exposed surface.
