Signal Head Mounting Set for Ground-Level Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of signal heads in transportation and traffic systems often requires personnel to work at height, which is dangerous and inefficient, with existing solutions like hydro hinged poles being expensive and requiring a large footprint, and slotted brackets being cumbersome.
Innovation Solution
A signal head mounting set with a base fastening kit and head fastening kit that allows for a plug-in-and-swing-in mounting system, utilizing pintles and studs for secure attachment, enabling easier and safer installation with reduced need for high ladders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If personnel climb a high ladder to install a signal head, then the signal head can be positioned and fastened, but the installation becomes dangerous and requires protective equipment
Solution Approach 1:
The mounting set enables ground-based installation by creating an equipotential working condition where the installer remains at ground level while the signal head is elevated. The base bracket is fastened to the pole base at ground level, and the signal head is lowered onto the mounting set, eliminating the need for the installer to work at height.
Solution Approach 2:
The traditional installation sequence is inverted: instead of lifting the signal head up to the installer, the base bracket is first attached to the pole base, then the signal head is lowered down onto the mounting set. This inversion allows ground-based installation and eliminates ladder climbing.
2Ease of manufacture
If a second installer is used to pass the signal head to the person on the ladder, then the signal head can be installed, but the installation process becomes more complex and requires coordination
Solution Approach 1:
The mounting set is divided into two separate brackets: a base bracket that remains attached to the pole base and a head bracket that attaches to the signal head. This segmentation allows the signal head to be lowered onto the base bracket while the installer remains on the ground, eliminating the need for a second installer to pass components upward.
3Productivity
If securing nuts and washers are fitted to U-Bolts before lifting the signal head, then the signal head can be secured, but the process requires precise positioning at height
Solution Approach 1:
The base bracket is pre-fastened to the pole base at ground level before the signal head is attached. This preliminary action establishes a stable mounting platform on the ground, allowing the signal head to be lowered and secured without requiring precise positioning operations at height.
Solution Approach 2:
The mounting set acts as an intermediary between the pole base and the signal head. It provides a mechanical interface that allows the signal head to be lowered and secured from ground level, eliminating the need for direct manual positioning and fastening at height.
4Reliability
If protective equipment is used to mitigate installation risks, then safety is improved, but the installation process becomes more cumbersome and expensive
Solution Approach 1:
The mounting set is designed to be self-contained and self-supporting. The base bracket fastens to the pole base with sufficient strength to support the signal head without requiring additional protective equipment or structural modifications. The system serves its own safety needs through its inherent design.
