Curb Broom Device Lateral Sweep Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brush devices for skidsteer vehicles are unable to effectively sweep and clear debris from newly formed curbs due to the lack of an offset and elevated brush mechanism.
Innovation Solution
A brush device with a frame attached to a vehicle, featuring a pivotally coupled rail and extendable brush arm with a rotatable brush, allowing lateral sweeping of surfaces offset from the vehicle, utilizing hydraulic components for adjustable positioning and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a conventional brush device is mounted directly on a skidsteer vehicle, then the device structure is simple, but the brush cannot reach lateral surfaces offset from the vehicle
Solution Approach 1:
The brush assembly is extended laterally from the vehicle in a direction perpendicular to the vehicle's forward motion, allowing the brush to reach surfaces offset from the vehicle path. This lateral extension resolves the contradiction by adding a dimensional component that increases reach without requiring excessive forward overhang.
Solution Approach 2:
The brush arm is made extendable and adjustable rather than fixed, allowing the operator to modify the brush's lateral position and reach. This dynamic adjustment capability enables the brush to adapt to different curb positions and distances, maximizing reach while maintaining a manageable frame structure.
2Ease of operation
If the brush is positioned laterally offset from the vehicle, then the brush can sweep curb surfaces, but the brush becomes difficult to control and position precisely
Solution Approach 1:
The system incorporates position sensing and control feedback mechanisms that allow the operator to monitor and adjust the brush arm's lateral position and angle. This feedback enables precise positioning of the brush relative to the curb while maintaining stability and sweeping effectiveness.
Solution Approach 2:
The frame structure is designed with multiple adjustment points and universal mounting capabilities that allow the brush to be positioned for various sweeping scenarios. This multi-functionality enables the same system to handle different curb configurations and positions while maintaining ease of operation and reliability.
3Adaptability or versatility
If the brush arm is made extendable laterally, then the brush can reach offset surfaces, but the device complexity increases
Solution Approach 1:
The brush arm is divided into segmented sections that can extend and retract independently along the lateral direction. This segmentation allows the brush to achieve extended reach while keeping each individual section manageable in size and complexity, reducing the overall structural burden.
Solution Approach 2:
The extendable brush arm uses a telescopic design where smaller sections are nested within larger sections, allowing compact storage when retracted and extended configuration when needed. This nesting principle reduces the complexity of the retracted state while maintaining full extendability for versatile operation.
