Adjustable Luminaire Sensor Housing for Flexible Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting fixtures with integrated sensors face challenges in flexible sensor placement, as the fixed location can interfere with aesthetics and effective monitoring, making it difficult to adjust the sensor's position after installation.
Innovation Solution
An adjustably attachable sensor housing that allows the sensor to be movably attached to the luminaire housing along the edge, using attachment structures like hooks, clips, or magnets, enabling flexible placement before and after installation without disrupting the lighting fixture's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sensor is mounted at a fixed location during manufacturing, then the sensor is securely attached to the luminaire housing, but the sensor location cannot be adjusted for aesthetic or functional reasons
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a fixed sensor mounting to a movable/adjustable mounting system. The sensor housing can be repositioned along the luminaire housing edge and remains secured through a mechanism that allows both movement and stable positioning, enabling adaptation to different aesthetic and functional requirements while maintaining secure attachment.
2Ease of operation
If the sensor is repositioned to a different location on the luminaire housing, then the aesthetic appearance and monitoring effectiveness are improved, but the installation and reconfiguration become more difficult
Solution Approach 1:
The patent applies segmentation by separating the sensor housing from the luminaire housing, allowing the sensor to be independently repositioned. The attachment mechanism is divided into distinct components (attachment structure on luminaire housing, corresponding receptacle on sensor housing) that enable easy connection and disconnection, simplifying repositioning operations.
Solution Approach 2:
The patent uses an intermediary attachment mechanism that mediates between the sensor housing and luminaire housing. This intermediate structure provides a standardized interface that simplifies the repositioning process, allowing the sensor to be easily attached, detached, and reattached at different locations without complex procedures.
3Reliability
If the sensor is integrated into the luminaire housing, then the sensor is protected and securely mounted, but the sensor location cannot be changed after installation
Solution Approach 1:
The patent resolves this contradiction by creating a dynamic mounting system where the sensor housing can be repositioned along the luminaire housing edge. The attachment mechanism provides stable securing at any position while allowing deliberate repositioning, combining the reliability of fixed mounting with the adaptability of adjustable positioning.

AI summary
A sensor assembly includes a sensor housing having an attachment end portion, and a sensor disposed at least partially in the sensor housing. The sensor housing is movably attachable to a luminaire housing of a luminaire. The attachment end portion is designed to be positioned on an edge of the luminaire housing to retain the sensor housing attached to the luminaire housing.
