Laterally Offset Curb Brush with Adjustable Roll Axis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brush devices lack the capability to sweep and clear debris from newly formed curbs, as they are not designed for offset and elevated sweeping, and cannot adapt to the configuration of the curb surface relative to the adjacent ground.
Innovation Solution
A curb brush device with a frame attached to a vehicle, featuring a pivotally coupled rail and brush arm that extends laterally, allowing the brush to sweep surfaces offset from the vehicle. The device includes a roll axis orientation adjustment assembly to adjust the brush's orientation and a motor to rotate the brush for effective debris removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional brush device is used, then the vehicle structure remains simple, but the device cannot sweep surfaces laterally offset from the vehicle
Solution Approach 1:
The brush assembly is positioned laterally offset from the vehicle's centerline, allowing it to sweep surfaces that are not directly in front of the vehicle. The rail extends laterally from the frame, and the brush arm can extend further laterally, creating a multi-dimensional sweeping capability that addresses surfaces at various lateral distances from the vehicle.
Solution Approach 2:
The brush arm is made extendable along the rail, allowing dynamic adjustment of the brush's lateral position. This extendable mechanism enables the brush to adapt to different sweeping requirements by moving along the rail to optimal positions, providing versatility without requiring a completely rigid complex structure.
2Adaptability or versatility
If the brush is fixed in position, then the device structure is simple, but the brush cannot adapt to different curb configurations
Solution Approach 1:
The brush arm can extend and retract along the rail, allowing dynamic positioning to adapt to different curb configurations. The roll axis orientation adjustment assembly allows the brush assembly to rotate about a roll axis, enabling the brush to conform to various surface angles and configurations of the curb being swept.
Solution Approach 2:
The adjustment system is divided into separate functional components: the rail for lateral positioning, the extendable brush arm for distance adjustment, and the roll axis orientation assembly for angular adjustment. This segmentation allows each component to be optimized independently while working together to provide comprehensive adaptability.
3Productivity
If the brush cannot rotate, then the device structure is simple, but the brush cannot effectively clear debris from the surface
Solution Approach 1:
The rotation of the brush is achieved through a motor coupled to the brush, replacing complex mechanical drive systems with a more efficient motorized rotation mechanism. This motor-driven rotation enables effective debris clearing while maintaining relatively simple overall device structure.
