Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pressure washing systems lack an efficient and cost-effective method to prevent damage to surfaces underneath the system when a spray gun component is used to clean adjacent or second surfaces.
Innovation Solution
A pressure washer system with a pump, pressure regulating valve, diversion block, and rotary nozzle system, where the system includes a first fluid path for cleaning surfaces underneath and a second fluid path that activates when needed to clean adjacent surfaces, using a valve trigger and rotary nozzle system to control fluid flow and pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a spray gun component is used to clean adjacent surfaces, then cleaning versatility is improved, but risk of damage to underlying surfaces increases
Solution Approach 1:
The fluid delivery system is segmented into two separate paths: a first fluid path for cleaning adjacent surfaces through the spray gun, and a second fluid path for cleaning underlying surfaces through the rotary nozzle system. This segmentation allows independent control of each cleaning path, enabling the operator to selectively activate only the spray gun for adjacent surfaces, thereby preventing damage to underlying surfaces while maintaining cleaning versatility.
Solution Approach 2:
A diversion block acts as an intermediary component that receives fluid from the pump and directs it to either the spray gun or the rotary nozzle system based on operational needs. This intermediary mechanism enables safe switching between cleaning modes, allowing versatile cleaning of different surface types while preventing harmful effects on underlying surfaces.
2Productivity
If fluid pressure is increased for efficient cleaning, then cleaning effectiveness is improved, but risk of surface damage increases
Solution Approach 1:
The system dynamically adjusts fluid pressure delivery by providing two distinct fluid paths with different pressure characteristics. The first fluid path delivers lower pressure suitable for adjacent surfaces, while the second fluid path delivers higher pressure for underlying surfaces. This dynamic pressure management allows efficient cleaning at appropriate pressure levels without causing damage.
Solution Approach 2:
Different parts of the fluid delivery system are designed with different pressure characteristics: the spray gun component in the first fluid path is optimized for lower pressure application to adjacent surfaces, while the rotary nozzle system in the second fluid path is optimized for higher pressure application to underlying surfaces. This local quality differentiation enables effective cleaning without surface damage.
3Device complexity
If a single fluid path is used for both cleaning modes, then system complexity is reduced, but ability to prevent surface damage is compromised
Solution Approach 1:
The pump and diversion block serve multiple functions: the pump provides fluid to both cleaning paths, and the diversion block directs fluid to either the spray gun or rotary nozzle system based on operational requirements. This multi-functionality allows the system to prevent surface damage through controlled fluid path selection while avoiding excessive complexity.

AI summary
Disclosed herein are various embodiments of a system and method for operating a surface pressure washer with a wand component. The method may include the steps of cleaning a first surface through a first fluid path, where the first fluid path includes a pump, a pressure regulating valve, a diversion block, and a spray gun, while spray nozzles are not discharging fluid to a second surface, actuating a valve connected to the diversion block, thereby reducing the pressure available to the first fluid path and creating a second fluid path, where the second fluid path includes the pump, the pressure regulating valve, the diversion block and the spray nozzles, where the spray nozzles are configured to rotate above the second surface when the second fluid path is open, and cleaning a second surface underneath the pressure washer system through the second fluid path.
