Surface cleaner system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface cleaners require frequent and independent movement of both the pressure washer and the cleaner when cleaning large surfaces, which is inefficient and labor-intensive.
Innovation Solution
A surface cleaner system with a base assembly that includes a movable housing, a pump for pressurizing fluid, and a spray assembly that can rotate to distribute fluid evenly, along with a spray gun that can connect to the base assembly for directed spraying or operate independently for hard-to-reach areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both the pressure washer and surface cleaner are moved independently when cleaning large surfaces, then the cleaning can be performed on different areas, but the operator effort and time required increases significantly
Solution Approach 1:
The patent combines the pressure washer and surface cleaner into a single integrated unit where the pressure washer is mounted on the surface cleaner housing. This merging eliminates the need to move two separate devices independently, allowing the operator to move one unified device to clean both large surfaces and hard-to-reach areas, thereby reducing operator time and effort while maintaining cleaning versatility.
2Measurement precision
If the spray gun is connected to the base assembly for directed spraying, then precise fluid application is achieved, but the system cannot reach hard-to-access areas
Solution Approach 1:
The spray gun is designed with a detachable connection to the base assembly through a quick-connect mechanism. This dynamic configuration allows the spray gun to switch between two states: connected to the base assembly for precise directed spraying on accessible surfaces, and disconnected for manual operation in hard-to-reach areas. The quick-connect feature enables rapid transition between these states, maintaining both precision and reachability.
3Stability of the object's composition
If the spray assembly is fixed in position, then fluid distribution is consistent, but the system cannot adapt to different cleaning scenarios
Solution Approach 1:
The spray system is segmented into a fixed spray assembly mounted on the base assembly and a detachable spray gun. The fixed spray assembly provides consistent fluid distribution when connected to the base assembly for large surface cleaning, while the detachable spray gun component enables adaptation for hard-to-reach areas. This segmentation allows the system to maintain stability in its primary function while gaining versatility through modular components.
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 system allows for efficient and continuous cleaning of large surfaces with reduced operator effort, as the base assembly can be moved easily and the spray gun can be used to reach areas where the base assembly cannot, maintaining consistent fluid distribution and pressure.
Implementation Method 1
a pump supported by the housing and operable to pressurize a fluid
Implementation Method 2
a spray assembly coupled to the housing. The spray assembly is operable to discharge fluid from the pump toward the surface

AI summary
A surface cleaner system includes a base assembly having a housing movable along a surface, a pump supported by the housing and operable to pressurize a fluid, and a prime mover supported by the housing. The prime mover is coupled to the pump to drive the pump. The surface cleaner system also includes a spray assembly coupled to the housing. The spray assembly is operable to discharge fluid from the pump toward the surface. The surface cleaner system further includes a spray gun in fluid communication with the pump to receive pressurized fluid from the pump. The spray gun includes an outlet portion that is connectable to the base assembly to direct the pressurized fluid from the pump into the spray assembly. When the outlet portion is disconnected from the base assembly, the spray gun discharges the pressurized fluid from the pump toward the surface without directing the pressurized fluid into the spray assembly.
