Electric Line Striper with Removable Reservoir Stage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wheeled line striping systems rely on internal combustion engines, which are noisy, emit fumes, and are cumbersome, limiting their use in indoor and sensitive environments, and are difficult to maneuver due to their weight and noise.
Innovation Solution
A line striper powered by an electric motor, with a removable stage for the fluid reservoir positioned over the rear axle to balance the weight and protect batteries, allowing for easier access and maneuverability, and using a battery configuration that positions batteries between the rear wheels for balance and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If an internal combustion engine is used to power the pump, then the pump can deliver sufficient power for paint application, but the system becomes noisy and emits fumes, limiting its use in indoor and sensitive environments
Solution Approach 1:
The patent replaces the internal combustion engine with an electric motor that draws power from a battery pack. This substitution eliminates the harmful emissions and noise associated with combustion engines while maintaining the necessary power output for the paint pump through electric motor propulsion.
2Productivity
If traditional wheeled line striping systems are used, then they can perform ground marking effectively, but they are heavy and difficult to maneuver
Solution Approach 1:
The patent implements a removable stage that can be detached from the main body of the line striper. This dynamic configuration allows the heavy fluid reservoir to be separated during transport, reducing the overall weight and improving maneuverability while maintaining full ground marking capability when the stage is attached.
3Device complexity
If the fluid reservoir is permanently mounted on the line striper, then the system structure is simplified, but the weight distribution becomes fixed and maneuverability is reduced
Solution Approach 1:
The patent divides the line striper into separable modules, including a removable stage for the fluid reservoir. This segmentation allows the system to maintain structural simplicity through standardized connection interfaces while enabling weight redistribution and improved maneuverability when components are detached or repositioned.
4Use of energy by moving object
If batteries are positioned in the line striper, then the system can operate electrically, but the batteries are vulnerable to damage and require easy access for maintenance
Solution Approach 1:
The patent places the battery pack within a protective cavity or compartment in the line striper frame. This nesting arrangement shields the batteries from external damage while maintaining accessibility through designated access panels or openings, allowing maintenance without complete disassembly of the system.
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 electric motor reduces noise and emissions, enabling indoor use and improving maneuverability by balancing the weight of the system, making it suitable for a wider range of environments and reducing user fatigue during operation.
Implementation Method 1
A line striper for ground marking with a sprayable fluid comprises a body, a removable stage for holding a fluid reservoir
