Interchangeable High-Pressure Washer Pump with Modular Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure washers and sprayers are cumbersome and limited in maneuverability due to their design, requiring users to move the entire device, including a heavy liquid tank, which restricts freedom of movement and leads to inefficiencies in use.
Innovation Solution
A device for discharging a pressurized liquid with a pump and lance connected via a solid joint allowing rotational and translational freedom, eliminating the need for a separate liquid tank and enabling use with an external motor, thus reducing weight and increasing mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pressure washer includes a liquid tank integrated in its structure, then it can operate independently, but the device becomes heavy and difficult to maneuver
Solution Approach 1:
The invention extracts the liquid tank from the pressure washer structure, allowing the device to operate without carrying its own liquid supply. The pressure washer can now draw liquid from external sources, eliminating the need for an integrated tank and reducing overall device weight while maintaining operational capability.
2Stability of the object's composition
If the pressure washer has a rigid body structure with integrated components, then it is structurally stable, but it reduces maneuverability and flexibility during use
Solution Approach 1:
The invention segments the pressure washer into separable components: the motor-pump assembly can be detached from the lance and hose assembly. This allows the user to carry only the necessary components during operation, improving maneuverability while maintaining structural stability when components are assembled and connected.
3Reliability
If the motor-pump assembly is positioned inside a body, then components are protected, but the device requires continuous movement of heavy mass and creates standing water in hoses
Solution Approach 1:
The invention extracts the motor-pump assembly from the enclosed body structure, allowing it to be positioned externally. This eliminates the need to continuously move heavy enclosed mass during operation and prevents standing water accumulation in hoses by enabling proper drainage and positioning, thereby improving operational efficiency while maintaining component protection through appropriate mounting.
4Ease of manufacture
If the pressure washer is designed as a single integrated structure, then it is easier to manufacture, but it cannot be transformed for different uses or shared with other devices
Solution Approach 1:
The invention segments the pressure washer into modular components (motor-pump assembly, lance, hose connections) that can be independently manufactured and then assembled. This modular design enables the same components to be configured for different uses, such as attaching the motor-pump assembly to different lances or applications, while maintaining manufacturing simplicity through standardized connection interfaces.

Function Achieved in This Case
The device allows for efficient and flexible operation by enabling the user to handle it as a single component, reducing weight and enhancing maneuverability, allowing use near any water source without the need to carry a liquid tank, thereby improving usability and reducing user fatigue.
