Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems lack a modular and relocatable sensor solution for controlling recessed luminaires, which is easy to install and integrate with existing ceiling constructions, to manage light output and energy usage based on environmental conditions.
Innovation Solution
A relocatable add-on sensor module with a modular design that can be easily integrated into t-bar grid systems, featuring a trim flange for clean installation, clamping mechanisms for secure attachment, and adjustable positioning, along with various sensors for motion, light intensity, and environmental control, allowing for flexible control of recessed luminaires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed integrated sensor system is used in recessed lighting, then the control function is built-in, but the system lacks flexibility and is difficult to relocate or reposition
Solution Approach 1:
The system is divided into separate functional modules: a sensor module that detects environmental conditions and a control module that interfaces with the lighting system. This segmentation allows the sensor module to be independently installed, removed, and repositioned without affecting the fixed lighting infrastructure, thereby achieving relocatability while maintaining system functionality
Solution Approach 2:
An intermediary control module serves as the bridge between the relocatable sensor module and the fixed lighting system. This intermediary handles the complex communication and control signals, allowing the simple sensor module to be easily relocated while the intermediary manages the integration complexity with the lighting system
2Ease of manufacture
If sensors are permanently integrated into luminaires, then control functionality is built-in, but installation is complex and requires modification of existing lighting systems
Solution Approach 1:
By separating the sensor functionality from the luminaire housing into an independent module, the system eliminates the need to modify existing lighting fixtures during installation. The sensor module can be independently manufactured and then simply attached to the ceiling grid, dramatically simplifying installation while maintaining full control functionality
Solution Approach 2:
The sensor module is designed with universal mounting capabilities that work with standard ceiling grid systems and can control multiple types of luminaires. This universal design allows a single module to serve multiple functions and locations, reducing installation complexity and enabling easy deployment without custom integration work for each luminaire
3Ease of operation
If a modular sensor module is used for easy installation, then installation simplicity is improved, but secure attachment to ceiling structures may be compromised
Solution Approach 1:
The mounting system uses dynamic clamping mechanisms that can be quickly engaged and disengaged by hand, providing easy installation and relocation. The clamps are designed to automatically tighten to secure strengths when engaged, maintaining strong attachment without requiring tools or complex procedures, thus achieving both installation simplicity and attachment strength
Solution Approach 2:
The mounting clips feature curved or rounded geometries that allow them to flex during installation and then conform tightly to the ceiling grid structures. This curvature enables simple snap-in installation while creating strong friction-based attachment that secures the module firmly to the ceiling structure

AI summary
A relocate able add-on control sensor module is described which electrically connects and controls at least one recessed light fixture. The relocate able add-on control module is mounted to a suspended ceiling t-bar grid and can be positioned anywhere in the ceiling grid while still controlling one or more recessed lighting fixtures. The control sensor module containing at least one sensor controlling light output of at least one recessed lighting fixture based on human occupancy, light intensity or both.
