Surface Cleaner Roller Clip Mount for Stable Ground Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lighter duty power washer surface cleaner attachments lack mobility as they directly contact the ground, causing the shroud to intermittently hover over the surface during use due to inadequate support, which affects cleaning efficiency.
Innovation Solution
A roller kit with a resilient clip system that secures a rotating roller to the surface cleaner attachment, allowing it to roll over the surface and guide the attachment's movement, featuring a bracket and clip configuration that bends to receive the shroud's side wall and rebounds to grip it for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If lighter duty power washer surface cleaner attachments directly contact the ground, then the device can be simpler in structure, but the mobility and cleaning efficiency deteriorate due to intermittent hovering over the surface
Solution Approach 1:
The patent introduces an intermediary component (roller or caster) between the shroud and the ground surface. This intermediary element provides continuous rolling contact that maintains consistent spacing between the shroud and surface, eliminating the intermittent hovering problem while keeping the overall device structure relatively simple.
Solution Approach 2:
The patent changes the contact parameter from direct static contact (shroud to ground) to rolling contact (roller/caster to ground). This parameter change transforms the interaction mode, allowing the shroud to maintain a consistent distance from the surface through the rolling mechanism, thereby improving cleaning efficiency without significantly increasing structural complexity.
2Productivity
If rollers are added to improve mobility, then cleaning efficiency improves, but device complexity increases
Solution Approach 1:
The roller or caster acts as a simple intermediary element that provides the necessary rolling function. By using a single, straightforward rolling component rather than a complex suspension or height-adjustment mechanism, the patent achieves improved mobility and cleaning efficiency while minimizing the increase in device complexity.
3Device complexity
If the shroud hovers intermittently over the surface, then the structure can remain simple, but the cleaning consistency and reliability deteriorate
Solution Approach 1:
The roller or caster serves as a reliable intermediary that ensures continuous and consistent contact with the ground surface. This consistent rolling contact maintains a stable distance between the shroud and surface, improving cleaning consistency and reliability without requiring complex active control systems or adjustable mechanisms.
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
Enhances the mobility and ease of use of power washer surface cleaner attachments by allowing them to smoothly traverse surfaces, improving cleaning efficiency and maneuverability, especially in units without sufficient pressure to maintain consistent contact.
Implementation Method 1
The clip is configured to bend resiliently in an opening direction to define an opening between the arm portion and the base portion for receiving a side wall of the shroud and to rebound in a gripping direction to grip the side wall between the arm portion and the base portion

AI summary
A roller kit for a power washer surface cleaner attachment. A roller mount includes a bracket mounting a roller for rotation with respect to the roller mount and a clip for securing the roller kit to the surface cleaner attachment such that the roller is operatively aligned with the surface cleaner attachment for rolling over a surface to guide movement of the surface cleaner attachment along said surface. The clip includes a base portion supporting the bracket and an arm portion opposing the base portion. The clip is configured to bend resiliently in an opening direction to define an opening between the arm portion and the base portion for receiving a side wall of the shroud and to rebound in a gripping direction to grip the side wall between the arm portion and the base portion and thereby secure the roller kit to the surface cleaner attachment.
