Pressure Washer Pump and Hose Reel Intersection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure washers require a large installation space due to the unfavorable arrangement of the high-pressure pump and hose reel, which leads to wasted space and material.
Innovation Solution
The high-pressure pump and hose reel are arranged such that the axis of rotation of the hose reel intersects the high-pressure pump, allowing them to be positioned very close to each other, thus reducing the need for a long connecting line and minimizing installation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the high-pressure pump and hose reel are arranged far apart in the conventional manner, then the components can be easily accessed and maintained, but the installation space is significantly increased and material is wasted
Solution Approach 1:
The patent changes the spatial arrangement by orienting the hose reel axis perpendicular to the piston movement direction, allowing the hose reel to be positioned adjacent to the high-pressure pump rather than behind it. This dimensional reconfiguration reduces the footprint in the piston movement direction while maintaining component accessibility through side access routes.
2Area of stationary object
If the high-pressure pump and hose reel are positioned close together, then installation space is minimized and portability is enhanced, but a long connecting line is required which increases device complexity
Solution Approach 1:
The patent merges the high-pressure pump and hose reel into a closely integrated assembly where the hose reel is positioned immediately adjacent to the pump. The connecting line is minimized by direct coupling, and the overall system is treated as a unified compact unit that achieves space efficiency without proportionally increasing complexity.
3Ease of manufacture
If the hose reel axis is oriented parallel to the piston movement direction, then the components can be arranged in a linear fashion simplifying manufacturing, but the installation space in the movement direction is significantly increased
Solution Approach 1:
The patent reorients the hose reel axis from parallel to perpendicular relative to the piston movement direction. This dimensional change allows the hose reel to be positioned in the transverse direction adjacent to the pump, converting a long linear arrangement into a compact L-shaped or T-shaped configuration that dramatically reduces the footprint in the piston movement direction.

AI summary
A pressure washer includes a high-pressure pump by which cleaning fluid can be pressurized in the pressure washer, a hose reel, which is mounted so that it can rotate about an axis of rotation, a reel hose, which can be wound onto and unwound from the hose reel, and a housing. The high-pressure pump is arranged in the housing and includes at least one piston, which can be moved back and forth in a direction of movement to generate pressure on the cleaning fluid. The high-pressure pump has a middle axis running in the direction of movement of the at least one piston. During the operation of the pressure washer, cleaning fluid can be conveyed to the reel hose by the high-pressure pump. The axis of rotation runs transversely to the direction of movement of the at least one piston. The axis of rotation intersects the high-pressure pump.
