Quick-Coupling Light Fixture Mounting With Plug-In Angular Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pole-mounted lights, such as streetlights, require complex adjustment mechanisms and numerous fastening components to achieve angular positioning, which complicates installation and increases the number of components needed to absorb significant torque from wind and weight forces.
Innovation Solution
A simplified adjustable fastening system using plug-in elements and support areas on the mast flange, allowing the lamp housing to be securely attached without screws, with multiple plug-in positions for angular adjustment and a spring or toggle lock for additional security, enabling easy assembly and reduced component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple screws or fasteners are used to secure the luminaire housing to the mast flange, then the connection can withstand significant torque from wind and weight forces, but the installation becomes more complex and time-consuming
Solution Approach 1:
The patent removes the traditional screw fastening system entirely, extracting only the essential functions of connection and positioning. The plug-in element with geometric interlocking replaces multiple fasteners, achieving secure attachment without requiring screws, nuts, or complex fastening mechanisms.
Solution Approach 2:
The connection system is designed to be self-securing through geometric interlocking. The plug-in element's shape and the corresponding receptacle geometry automatically provide mechanical engagement and torque resistance without requiring additional fastening components or complex assembly procedures.
2Adaptability or versatility
If a complex adjustment mechanism with multiple components is used to achieve angular positioning, then precise angular adjustment is possible, but the device complexity and number of components increase
Solution Approach 1:
The angular adjustment is achieved by segmenting the possible positions into discrete angular increments. The plug-in element can be inserted into different angular positions on the mast flange, providing stepwise adjustment capability without requiring a continuous complex mechanism. This segmentation approach delivers sufficient positioning precision while maintaining system simplicity.
3Reliability
If numerous fastening components are used to secure the luminaire, then the connection can withstand wind and weight forces, but the installation time increases
Solution Approach 1:
The patent extracts and eliminates the time-consuming screw fastening operation entirely. The plug-in element system requires only simple insertion and geometric engagement, removing the need for tools, multiple fasteners, and complex assembly steps while maintaining secure mounting capability through geometric interlocking.
4Force
If multiple screws are used to attach the luminaire housing, then the connection can absorb significant torque, but the number of components and assembly steps increases
Solution Approach 1:
The patent merges multiple fastening functions into a single integrated plug-in element. This single component simultaneously provides positioning, connection, and torque resistance that would traditionally require multiple separate fasteners. The geometric interlocking design consolidates the functions of multiple screws into one unified element.

AI summary
The invention relates to a light fixture for fastening to a post, the light fixture having the following: a light fixture housing in which lamps are arranged to emit light through a light exit surface of the light fixture; and a post flange which has a receptacle for fastening to an end of a lamppost. The post flange is mountable on the light fixture housing in different angular positions so that the light exit surface can be positioned in different positions relative to the receptacle. The light fixture housing has an insertion region having multiple insertion positions into which an insertion element of the post flange can be electively inserted, and the light fixture housing has a contact face which is supported on a supporting region, spaced from the insertion region, of the post flange when the insertion element is inserted in any of the insertion positions.
