Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light panels and lamps face challenges with mount assemblies that obscure access to hardware, interfere with cable rotation, and require additional space for use and storage, making them difficult to reorient and operate efficiently.
Innovation Solution
A lighting assembly with an adjustable mount that includes a mounting assembly configured to pass through the center of gravity, allowing for easy adjustment and storage without interfering with cables, featuring a channel for translational movement and rotational adjustment via joints, enabling the lighting apparatus to be stowed within its perimeter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional mount assembly is used to attach lighting apparatus to a support, then the lighting apparatus can be secured to the support, but the mount assembly obscures access to hardware and interferes with cable rotation
Solution Approach 1:
The mounting assembly is divided into separate functional components: a mounting plate for attachment to the support, a mount arm for positioning, and a first joint for rotation. This segmentation allows each component to be optimized independently and facilitates easier access to hardware on the lighting apparatus by distributing mounting functions across multiple elements rather than a single obstructive assembly.
Solution Approach 2:
The pivot axis is extracted and positioned to pass through the center of gravity of the lighting apparatus, separating the rotational function from the mounting structure. This extraction allows the mount assembly to be more compact and less obstructive, while cables can rotate freely around the pivot axis without interference from mounting hardware.
2Adaptability or versatility
If a conventional mount assembly with external mounting structure is used, then the lighting apparatus can be adjusted to different orientations, but additional space is required for use and storage
Solution Approach 1:
The mount arm is designed to nest within the perimeter of the lighting apparatus when in the stowed position. The mount arm can be positioned inside the boundary defined by the frame of the lighting apparatus, allowing the entire mounting assembly to be stored within the footprint of the lighting apparatus itself, minimizing additional space requirements for storage and transport.
Solution Approach 2:
The mounting assembly incorporates dynamic elements including a first joint that enables rotation of the mount arm relative to the mounting plate, and a second joint that enables rotation of the lighting apparatus relative to the mount arm. These dynamic joints allow the assembly to adapt to different orientations and positions, providing versatility while maintaining a compact stowed configuration.
3Ease of operation
If the pivot axis is offset from the center of gravity, then the mounting assembly can be simpler in design, but the lighting apparatus is harder to balance and reorient
Solution Approach 1:
The pivot axis is positioned to pass through the center of gravity of the lighting apparatus, creating a balanced configuration where the apparatus can be easily reoriented without excessive torque requirements. This equipotential positioning ensures that the lighting apparatus can be rotated to any orientation with equal ease, as the center of gravity remains aligned with the rotation axis, eliminating the need for complex balancing mechanisms.

AI summary
A lighting assembly includes a lighting apparatus that includes a component housing that receives a light source and first and compartments for housing electronic components, the second compartment spaced from the first compartment by a channel. The lighting apparatus includes a mounting assembly that includes a first joint received within the channel, coupled to the component housing, and translatable along the channel between a use position and a stowage position. The mounting assembly also includes a mount arm coupled to the component housing by the first joint and rotatable relative to the joint about a pivot axis. When the first joint is in the use position the pivot axis extends through a center of gravity of the lighting apparatus.
