Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting fixtures lack flexibility and ease of installation, particularly in terms of adjusting orientation and securing to various ceiling types, such as junction boxes and recessed cans, due to limited rotational movement and securement mechanisms.
Innovation Solution
A lighting arrangement featuring a luminaire with a housing assembly and spring arms that extend along a torturous path, allowing for rotational adjustment and securement to different ceiling types through a receiving aperture, enabling easy alignment and locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a lighting fixture uses a fixed mounting structure, then it provides stable attachment to the ceiling, but it lacks flexibility for rotational adjustment and orientation changes
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed mounting structure into a dynamic system with spring arms that can rotate and adjust. The spring arms are designed to be flexible yet maintain engagement through their elastic properties, allowing the luminaire to rotate and reposition while remaining securely attached to the ceiling mounting structure.
Solution Approach 2:
The mounting system is segmented into separate components: the ceiling mounting structure, the spring arms, and the luminaire housing. This segmentation allows independent optimization of each component - the mounting structure provides stable attachment points, while the spring arms provide flexible rotational capability, resolving the contradiction between stability and flexibility.
2Adaptability or versatility
If a lighting fixture uses a complex securement mechanism for various ceiling types, then it achieves versatile attachment options, but it increases installation complexity
Solution Approach 1:
The spring arms are designed with universal engagement features that can attach to multiple ceiling types (junction boxes, recessed cans, etc.) through a single standardized interface. The spring arms' elastic tips can accommodate different mounting surface geometries without requiring different securement mechanisms, achieving versatility while maintaining simplicity.
Solution Approach 2:
The spring arms utilize parameter changes in their elastic properties to adapt to different ceiling types. By varying the spring constant, arm length, and tip geometry within a single design family, the system achieves adaptability across multiple ceiling configurations without increasing overall mechanism complexity.
3Ease of operation
If spring arms extend along a straight path, then the structure is simple and easy to manufacture, but it cannot provide rotational adjustment capability
Solution Approach 1:
The spring arms incorporate curved and torturous paths instead of straight lines, allowing rotational movement while maintaining spring functionality. The curved geometry enables the arms to flex and rotate within their elastic limits, providing orientation adjustment capability. These curved paths can be manufactured using standard spring forming processes, keeping manufacturing complexity manageable.

AI summary
A lighting arrangement can include a luminaire and a first plurality of spring arms. The luminaire can include a housing assembly and a light emitter portion at least partially enclosing the light emitter portion. The first plurality of spring arms can each be engageable with the luminaire and extend from a respective base end to a respective distal end. The base ends can be positioned closer to the housing assembly than the distal ends. Each of the first plurality of spring arms can extend vertically upward and away from the housing assembly along the axis such that the base ends are vertically lower than the distal ends. Each of the first plurality of spring arms can extend along a torturous path and be cantilevered off of the housing assembly.
