Lighting Fixture Assembly With Pre-Configured Mounting Tube
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting fixture assemblies for masts are labor-intensive and prone to incorrect settings during installation, as they require precise adjustment of multiple LED light sources, which can shift during transportation and storage, leading to costly reconfiguration on-site.
Innovation Solution
A lighting fixture assembly with a cylindrical tube part and fixture coupling pieces that allow adjustment over two axes, featuring predrilled bores for secure positioning, reducing the need for continuous adjustments and ensuring fixtures are correctly aligned before installation, using a limited set of discrete angles and rotation settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If lighting fixtures are adjusted manually on-site to achieve correct beam configuration, then the light beam can be aligned properly, but the installation becomes time-consuming and expensive requiring skilled engineers
Solution Approach 1:
The lighting fixtures are pre-configured in the factory with precise angular adjustments and secured in their final positions before shipping. The mounting element includes pre-drilled holes and positioning features that ensure correct installation orientation without requiring on-site adjustment, thereby eliminating time-consuming manual alignment while maintaining precision
Solution Approach 2:
The mounting element is divided into modular components including a mounting plate with multiple pre-configured fixture holders, each capable of independent positioning. This segmentation allows fixtures to be pre-assembled in correct configurations and enables rapid installation by simply mounting the entire assembly rather than adjusting each fixture individually
2Productivity
If lighting fixtures are secured to the mounting element beforehand, then installation time is saved, but the fixtures may shift during transportation and storage resulting in incorrect configuration
Solution Approach 1:
The fixture holders on the mounting element include built-in clamping mechanisms and securing features that are activated during installation to lock fixtures in place. These mechanisms prevent any shifting during transportation while allowing quick release and positioning during installation, thus maintaining both stability and installation speed
Solution Approach 2:
A specialized mounting bracket or coupling mechanism serves as an intermediary between the lighting fixture and the mounting element. This intermediary component provides secure attachment points that prevent movement during transport while enabling rapid installation through simple connection actions, thereby maintaining both reliability and productivity
3Adaptability or versatility
If multiple adjustment freedoms are provided for lighting fixtures, then the light beam can be precisely configured, but the setting operation becomes labor-intensive and requires significant accuracy
Solution Approach 1:
The mounting element provides different types of adjustment mechanisms for different fixtures based on their specific requirements. Some fixtures have fixed positions, others have limited angular adjustment, and some have full rotational capability. This localized differentiation maintains beam configuration flexibility while reducing overall operational complexity by providing only the necessary adjustment freedoms for each position
Solution Approach 2:
The optimal angular positions and orientations for all lighting fixtures are pre-calculated and pre-marked on the mounting element during design. This includes pre-drilled holes at correct angles, pre-positioned fixtures, and clear installation markings that guide workers to the correct configuration without requiring complex calculations or adjustments on-site, thereby maintaining versatility while simplifying operation
