Pivoting Anti-Tipping Roller Support for Wheeled Electrical Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wheeled electrical equipment, such as circuit breakers, have a high center of gravity due to the placement of mass at the upper portion, leading to a tipping risk during movement, especially on uneven surfaces, which can cause damage to the equipment and operators.
Innovation Solution
An anti-tipping device with a pivotally mounted wheel mount and roller system that can transition between a folded and unfolded position, providing auxiliary support to prevent toppling, comprising a support structure, a pivotally mounted wheel mount, and a retaining device using tension springs for stabilization, allowing the rollers to adapt to inclined surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the main mass is located at the upper portion of the wheeled electrical equipment, then the structural design is simplified, but the center of gravity position becomes high causing tipping risk
Solution Approach 1:
The patent introduces a counterweight mechanism consisting of a counterweight block and counterweight rod that extends downward from the upper portion of the equipment. This counterweight structure compensates for the high center of gravity caused by placing main mass at the upper portion, thereby reducing the tipping risk while maintaining the simplified structural design benefit
2Stability of the object's composition
If a fixed support structure is used to prevent tipping, then stability is improved, but the device complexity increases
Solution Approach 1:
The patent employs a dynamic support structure with a wheel mount that can pivot between a folded position (adjacent to the equipment) and an unfolded position (extending outward). This movable structure provides stability during movement when needed, while remaining compact and simple when not in use, thus improving stability without permanently increasing device complexity
Solution Approach 2:
The support structure is divided into separable components: a wheel mount, rollers, and a counterweight mechanism. These segmented parts can be deployed independently when needed for stability and retracted when not required, allowing the system to maintain simplicity while providing enhanced stability during critical operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The anti-tipping device effectively reduces the risk of equipment toppling during movement by providing additional support, ensuring stability and safety without hindering the operation of the electrical equipment, even on uneven surfaces.
Implementation Method 1
The retaining device may comprise a tension spring, one end of which is attached to the support and the other end of which is attached to the wheel mount
Implementation Method 2
the wheel mount is away from the electrical equipment to enable the rollers to roll relative to a support surface at a predetermined distance from the electrical equipment
