Luminaire Connection Using Angled Catch and Segmented Fastener
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminaire connection systems face challenges in providing a secure and discreet connection between luminaires, especially in spatially constrained environments where traditional connection methods are not effective.
Innovation Solution
A system comprising a first luminaire with a receiving portion angled upward and a catch, and a second luminaire with a moveable arm and threaded opening, utilizing a threaded fastener with a head diameter greater than the catch width and a shank diameter smaller than the catch, allowing for progressive alignment and tightening to secure the connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connection methods are used, then the connection structure is simple, but the connection is not secure and not discreet in spatially constrained environments
Solution Approach 1:
The fastener head is nested within the plane of the receiving portion, with the fastener shaft passing through the catch feature. When tightened, the fastener head sits flush with or recessed into the receiving portion surface, creating a discreet connection that appears integrated rather than attached with visible hardware.
Solution Approach 2:
The catch feature extends beyond the plane of the receiving portion in a third dimension, allowing the fastener to engage from a different spatial plane. This enables secure connection in constrained environments where traditional in-plane fastening would not work, while the final appearance remains flush with the surface.
2Reliability
If the fastener head diameter is larger than the catch width, then the connection is more secure, but the fastener cannot pass through the catch
Solution Approach 1:
The fastener is segmented into two distinct parts: a head portion with diameter larger than the catch width for secure clamping, and a shaft portion with diameter smaller than the catch width for passage through the catch. This segmentation allows each part to fulfill its specific function - the shaft passes through easily while the head provides secure retention.
Solution Approach 2:
The system transitions from an initial state where the fastener is loose and the arm is in a first position, to an intermediate state where the arm moves to a second position bringing luminaires into contact, resulting in a final tightened state. This dynamic sequence allows the fastener to be installed easily first, then secured tightly afterward.
3Ease of operation
If the arm is held in the raised position during connection, then alignment is easier, but additional support structures are needed
Solution Approach 1:
The arm's own weight provides the necessary support when in the lowered position, eliminating the need for additional support structures. During installation, the arm naturally settles into the lowered position under gravity, automatically providing stable support for the connection process without requiring external bracing or support mechanisms.

Function Achieved in This Case
Enables a secure and discreet connection between luminaires, even in limited spaces, with the system adapting to varying distances and angles to ensure a tight clamp, enhancing the stability and aesthetics of luminaire installations.
Implementation Method 1
a first threaded fastener comprising a head and a threaded shank for threading engagement with the threaded opening of the second luminaire
Implementation Method 2
the arm of the second luminaire is lowered from the raised position to the lowered position by gravity
