Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing and aiming light emitting diode (LED) luminaires in large and complex environments, such as sports arenas, are labor-intensive, prone to human error, and difficult to achieve precise orientation due to environmental factors like wind and precipitation, leading to inefficiencies in field installation time and accuracy.
Innovation Solution
A lighting device with a mounting structure that includes a housing with an interface plate featuring tilt apertures and a fastening device, allowing for precise pivotal mounting and locking of the light fixture at predetermined tilt angles, enabling accurate pre-aiming and easy adjustment of the lighting device's orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment and aiming of light fixtures is performed by workers elevated high in the air or standing on towers, then the light fixtures can be installed and oriented, but the process becomes labor-intensive, time-consuming, and prone to human error due to difficult working conditions
Solution Approach 1:
The light fixture is pre-assembled on the ground with the mounting structure and interface plate before being elevated to the installation location. This preliminary assembly allows workers to prepare the fixture in a safe, accessible environment, reducing the complexity and time of work performed at height.
Solution Approach 2:
The mounting system is divided into separate components: the light fixture, the mounting structure with pivot axis, and the interface plate with aperture. This segmentation allows for independent assembly and adjustment of each component, simplifying the overall installation process and reducing the need for complex adjustments at height.
2Manufacturing precision
If manual adjustment and aiming of light fixtures is performed by workers elevated high in the air or standing on towers, then the light fixtures can be installed and oriented, but the precision of orientation is reduced due to environmental factors like wind and precipitation
Solution Approach 1:
The interface plate with precisely positioned aperture is assembled at ground level in a controlled environment, ensuring high precision orientation without exposure to environmental factors. The pre-assembled fixture is then elevated and locked into position, protecting the precision work from wind and precipitation.
Solution Approach 2:
The mounting structure incorporates a self-aligning mechanism where the aperture in the interface plate automatically aligns with the pivot axis when the fixture is mounted, eliminating the need for manual alignment adjustments at height and ensuring precise orientation without human intervention in harsh conditions.
3Manufacturing precision
If accurate preliminary aiming is performed at the manufacturer or assembler, then the device orientation can be pre-set, but errors are introduced during assembly and installation that compound the orientation inaccuracies
Solution Approach 1:
The interface plate acts as an intermediary component that provides a precise mechanical reference (aperture) for orientation. This intermediary element ensures that the pre-assembled fixture maintains its orientation accuracy during installation, as the aperture-pivot axis alignment serves as a reliable reference that prevents error compounding.
Solution Approach 2:
The fixture is pre-assembled on the ground with the mounting structure and interface plate before being elevated to the installation location. This preliminary assembly allows workers to prepare the fixture in a safe, accessible environment, reducing the complexity and time of work performed at height.

AI summary
This document describes a mounting structure that is used to pivotally mount and orient a lighting device with respect to a support structure. The light fixture includes an interface plate having at least one tilt aperture. Each tilt aperture corresponds to a tilt angle of the light fixture. The mounting structure includes a mounting slot for engaging with a mounting element of the interface plate, along with a semi-circular slot that overlaps the at least one tilt aperture when the light fixture is pivotally mounted on the mounting structure. The mounting structure also includes a fastening device that, when routed through the semi-circular slot for insertion into the tilt aperture, orients the light fixture pivotally mounted on the mounting structure at a tilt angle. The fastening device is lockably engaged within the semi-circular slot at a position corresponding to the tilt angle.
