Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional rotating brackets for linear luminaires are high-profile and unsuitable for many installations due to their height, which limits their versatility and application in various settings.
Innovation Solution
A rotating bracket system comprising an endcap, fastener, support, and securement structure that attaches internally to the linear lighting channel, allowing for precise positioning and reduced profile, along with a ferromagnetic base for pivoting, utilizing permanent magnets for secure attachment and rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional rotating bracket is designed to attach entirely to the exterior of a linear luminaire, then the bracket provides functional rotation capability, but the bracket becomes high-profile and unsuitable for many installation types
Solution Approach 1:
The rotating bracket mechanism is nested within the linear luminaire channel itself. The channel is designed with internal features (slots, endcaps with openings) that accommodate the rotation mechanism, allowing the bracket to be contained within the luminaire's existing profile rather than extending outward. This nesting approach enables rotation functionality while maintaining a low-profile installation suitable for various mounting surfaces.
2Length of stationary object
If a rotating bracket is designed with internal attachment to reduce profile, then the bracket achieves low-profile installation, but the attachment mechanism becomes more complex
Solution Approach 1:
The linear luminaire channel serves multiple functions: it houses the LED light source, provides structural support, enables rotation through internal slots and endcaps, and facilitates mounting to various surfaces. By making the channel multi-functional, the design avoids adding separate complex attachment mechanisms, as the channel itself is engineered to perform both structural and rotational functions.
Solution Approach 2:
The attachment mechanism is segmented into discrete, simple components: endcaps with keyed openings, slots in the channel, and corresponding fasteners. Rather than a single complex integrated mechanism, the system uses multiple simple elements that work together, making the overall attachment system easier to manufacture and assemble despite the low-profile requirement.
3Adaptability or versatility
If a low-profile rotating bracket is designed, then the bracket becomes suitable for various installation types, but the structural integrity may be compromised
Solution Approach 1:
The linear luminaire channel and bracket components are designed as composite structures that combine multiple materials or material properties to achieve both low-profile dimensions and high structural integrity. The channel may combine rigid materials for structural support with integrated rotational mechanisms, while endcaps and fasteners use complementary materials to ensure secure attachment without requiring a high-profile design.

AI summary
A rotating bracket includes an endcap, a fastener, a support, a spacer, and securement structure. The endcap is adapted to fit an end of a linear lighting channel and has a keyed opening. The fastener has a keyed shank complementary to the keyed opening of the endcap and is adapted to be inserted into the endcap with the keyed shank of the fastener engaging the keyed opening of the endcap. The support has a slot or opening adapted to accommodate the fastener. The spacer is adapted to insert over the fastener such that it is positioned between the endcap and an inner face of the support. The securement structure engages the end of the fastener beyond an outer face of the support. Linear luminaires using the rotating bracket are also disclosed.
