Streetlight Bracket Reinforcement Using Split Mounting Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connections between streetlight mounting brackets and utility poles often rely on a single fastener, which reduces the structural integrity and increases susceptibility to damage from adverse weather conditions.
Innovation Solution
A device comprising first and second mounting arms with wedge-shaped bases and slots, along with an optional adapter, that uses a single fastener to secure the mounting bracket to the pole, providing enhanced stability and resistance to movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only one fastener is used to secure the mounting bracket to the pole, then the installation process is simpler and faster, but the structural integrity and resistance to adverse weather conditions deteriorates
Solution Approach 1:
The mounting arm is divided into multiple segments (first mounting arm and second mounting arm) that can be independently positioned on opposite sides of the pole. Each segment has its own slot for fastener engagement, allowing the single fastener to secure multiple distributed attachment points rather than a single concentrated point, thereby improving connection stability while maintaining installation simplicity
Solution Approach 2:
The invention transitions from a single-point attachment to a multi-point attachment by distributing fastener engagement across opposite sides of the pole (spatial dimension). The slots in the mounting arms engage the fastener at different locations around the pole circumference, creating a three-dimensional securement pattern that enhances structural integrity without complicating the installation process
2Reliability
If multiple fasteners are used to secure the mounting bracket to the pole, then the connection stability and resistance to adverse weather conditions improves, but the installation process becomes more complex and time-consuming
Solution Approach 1:
The first and second mounting arms are combined into a single integrated device that uses one fastener to secure both arms to the pole. The fastener passes through slots in both mounting arms simultaneously, merging multiple attachment functions into a single fastening operation. This eliminates the need for multiple separate fasteners and installation steps while maintaining the stability benefits of multi-point attachment
Solution Approach 2:
The single fastener serves multiple functions by engaging with both the first and second mounting arms that are positioned on opposite sides of the pole. This universal fastener design allows one component to perform the work of multiple fasteners, simplifying the installation process while maintaining connection stability across different pole configurations

AI summary
A device for reinforcing a connection between a mounting bracket and a pole includes a first mounting arm having a first base with a first slot. A first projection extends from the first base for engaging a first side of the pole. A second mounting arm includes a second base with a second slot and a second projection extending from the second base for engaging a second side of the pole. A single fastener extends through the first and second slots in the first and second mounting arms, an opening in the mounting bracket, and into the pole for fixing the device to the pole.
