Lighting Arrangement Dual Spring Arm Tool-Free Junction Box Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting arrangements require additional holes in ceilings or walls for installation and often necessitate tool usage for assembly, complicating the installation process and potentially leading to misalignment.
Innovation Solution
A lighting arrangement featuring a dual spring arm system that allows for tool-free assembly and alignment, attaching directly to a standard junction box without protruding into it, using a luminaire and mounting bracket with spring arms that slide and deform to securely engage, providing tactile feedback upon successful assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional lighting arrangements are installed using additional holes in ceilings or walls, then secure mounting is achieved, but installation complexity increases and alignment difficulties arise
Solution Approach 1:
The mounting system is divided into separate components: a mounting bracket that attaches to the junction box and spring arms that connect the luminaire to the bracket. This segmentation allows each component to be optimized independently and simplifies installation by eliminating the need for additional holes in ceilings or walls
Solution Approach 2:
The spring arms are received within slots defined by the mounting bracket and luminaire, creating a nested structure. The spring arms fit into the slots and engage with engagement features, providing secure mounting without requiring additional structural modifications to the building
2Strength
If traditional lighting arrangements require tool usage for assembly, then strong engagement is achieved, but installation time increases and ease of installation decreases
Solution Approach 1:
The spring arms are designed as flexible, deformable elements that can be easily positioned and then automatically engage with the luminaire and mounting bracket. The spring arms deform during installation to slide across each other and into their final engaged position, providing strong holding strength without requiring tools
Solution Approach 2:
The spring arms automatically engage with the luminaire and mounting bracket through their own elastic deformation and spring force. The engagement features on the spring arms self-align and self-engage with corresponding features on the luminaire and bracket, eliminating the need for external tools or complex adjustment procedures
3Manufacturing precision
If spring arms are designed to slide across each other during assembly, then alignment precision is improved, but structural complexity increases
Solution Approach 1:
The spring arms feature an asymmetric geometry with a first bend, second bend, and third bend at different positions along their length. This asymmetric design allows the spring arms to slide across each other in a controlled manner during assembly while maintaining structural integrity and achieving precise alignment in the final assembled position

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy, tool-free installation directly into junction boxes with improved holding strength and alignment assurance, eliminating the need for additional holes and simplifying the installation process while ensuring secure mounting.
Implementation Method 1
The at least one first spring arm and the at least one second spring arm can slide across each other as the luminaire and the mounting bracket are moved closer together along an assembly axis

AI summary
A lighting arrangement can include a mounting bracket, a luminaire, at least one first spring arm, and at least one second spring arm. The mounting bracket can be releasably mountable to at least one of a junction box, a wall and a ceiling. The luminaire can extend along a longitudinal axis between a light emanating face and a rear face. The at least one first spring arm can extend between a base end and a distal end wherein the base end can be mounted to a first of the mounting bracket and the luminaire. The at least one second spring arm can extend between a base end and a distal end wherein the base end of the at least one second spring arm can be mounted to a second of the mounting bracket and the luminaire.
