Spring-Loaded Hose Reel Assembly for Pressure Washer Hose Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure washers face difficulties with loose high-pressure hoses that are stiff and cumbersome to handle, and manual hose reels require physical effort to operate, especially when dealing with long and heavy hoses.
Innovation Solution
A self-winding hose reel assembly for pressure washers, featuring a fastening mechanism that secures the reel to the pressure washer's frame, allowing it to rotate between vertical and horizontal positions, and includes a spring-actuated drum for automatic hose winding and unwinding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual hose reel is used to store and manage the high-pressure water hose, then the hose management convenience is improved, but the user experience deteriorates due to the physical effort required to manually crank the handle, especially when the hose is long and heavy
Solution Approach 1:
The hose reel is designed with a self-winding mechanism that automatically winds the hose onto the drum without requiring manual cranking. The spring-loaded reel activates itself when the hose is pulled out, providing self-service functionality that eliminates the physical effort previously needed to operate the reel while maintaining convenient hose management
Solution Approach 2:
The spring mechanism is pre-loaded and ready to automatically wind the hose as soon as it is pulled out. This preliminary preparation of the winding mechanism ensures that the hose is automatically retracted without requiring user intervention, resolving the contradiction between ease of operation and physical effort
2Power
If the high-pressure water hose is made stiff to handle pressurized water effectively, then the water delivery performance is improved, but the ease of operation deteriorates as users experience difficulties when handling the stiff hose
Solution Approach 1:
The self-winding reel automatically manages the stiff hose by winding it onto the drum using spring force. This self-service mechanism compensates for the hose's stiffness, allowing the hose to maintain its rigid structure for effective water delivery while the reel handles the manipulation tasks that would otherwise be difficult for users
Solution Approach 2:
The hose reel acts as an intermediary between the user and the stiff hose. Instead of the user directly handling the difficult-to-manipulate hose, the reel mediates by automatically winding and unwinding it, thus resolving the contradiction between maintaining hose stiffness for power and improving ease of operation
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 self-winding hose reel provides convenient and effortless management of high-pressure hoses, reducing user effort and enhancing usability by automatically winding and unwinding the hose during use and storage.
Implementation Method 1
The hose reel may include a housing, a spring-loaded reel disposed in the housing and configured to rotate about an axis, and a water hose wound on the reel

AI summary
An assembly for high-pressure cleaning and a method for manufacturing an assembly for high-pressure cleaning are provided. The assembly includes a self-winding hose reel, a pressure washer, and a fastening mechanism. The pressure washer includes a pump and a frame. The frame includes a first side pipe and a second side pipe parallel to the first side pipe. The fastening mechanism is designed to secure the self-winding hose reel to the frame between the first side pipe and the second side pipe. The fastening mechanism allows rotation of the self-winding hose reel with respect to a plane formed by the first side pipe and the second side pipe.
