Line Striper With Deployable Sweeper for Debris Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing line stripers face challenges in efficiently removing debris from surfaces before applying paint or other materials, leading to inconsistent application quality and increased effort due to the need for manual sweeping, which can be time-consuming and prone to delays, especially in outdoor environments where debris accumulation is rapid.
Innovation Solution
A line striper equipped with a debris removal system that includes a rotating brush or contact mechanism to apply consistent friction and dislodge debris, integrated with a material deployment system and actuated by a controller for autonomous operation, ensuring effective debris removal before material application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual sweeping is used to remove debris before painting, then labor flexibility is maintained, but time consumption increases and application quality becomes inconsistent
Solution Approach 1:
The patent combines the debris removal system and paint application system into a single integrated line striper unit. The debris removal mechanism (rotating brush) and paint spray gun are positioned one after another on the same device, allowing continuous operation without time loss between sweeping and painting operations.
Solution Approach 2:
The debris removal system performs preliminary cleaning action automatically before the paint application system operates. The rotating brush clears the surface in advance, ensuring the paint is applied to a clean surface without requiring separate manual sweeping steps.
2Reliability
If a fixed debris removal system is installed on the line striper, then debris removal consistency is improved, but adaptability to different working conditions deteriorates
Solution Approach 1:
The debris removal system employs a rotating brush that can dynamically adjust its operation. The brush rotation speed and contact pressure with the surface can be modified to adapt to different pavement types and debris conditions, maintaining consistent cleaning performance across varying working conditions.
Solution Approach 2:
The system allows parameter adjustments including brush rotation speed, brush contact force, and paint application pressure. These parameters can be changed to optimize performance for different surface types (asphalt, concrete) and debris conditions while maintaining reliable debris removal.
3Productivity
If an integrated debris removal and painting system is used, then operational efficiency is improved, but device complexity increases
Solution Approach 1:
The line striper is designed as a multi-functional device that performs both debris removal and paint application using a single power source (engine) and control system. The hydraulic system serves dual purposes by powering both the brush rotation and paint pump, reducing overall system complexity despite the integrated functionality.
Solution Approach 2:
The system operates autonomously with the engine automatically powering both the debris removal brush and the paint application system. The hydraulic fluid circulation system self-regulates to provide power to both mechanisms without requiring separate operators or control systems for each function.
