Self-Winding Hose Reel Layout for Stable Pressure Washers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure washers require manual effort to wind and unwind high-pressure hoses, which can be tiresome, and elevated hose reels pose stability issues leading to safety hazards.
Innovation Solution
A self-winding hose reel system for pressure washers that automatically winds and unwinds the hose, integrated with a handle mechanism that rotates between vertical and horizontal positions, ensuring stable placement and reducing manual effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual hose reel is used, then hose storage is improved, but ease of operation deteriorates due to physical effort required
Solution Approach 1:
The hose reel system performs self-service by automatically winding the hose back onto the reel using a spring mechanism. When the user releases the hose, the spring automatically winds it back without requiring manual intervention, thus eliminating the need for physical cranking effort while maintaining hose storage capability
Solution Approach 2:
The spring mechanism is pre-loaded with potential energy before use. This preliminary action stores energy that is then released to automatically wind the hose, eliminating the need for the user to perform the winding action manually each time
2Ease of operation
If hose reel is placed elevated on frame, then hose management is improved, but stability deteriorates causing tipping hazard
Solution Approach 1:
The hose reel system is segmented into a separate, self-contained unit with its own housing and mounting structure. This allows the reel to be positioned elevated for convenient hose access while the housing and mounting design ensure it does not compromise the overall stability of the pressure washer frame
Solution Approach 2:
A dedicated mounting structure acts as an intermediary between the elevated hose reel and the pressure washer frame. This intermediary component provides stable support for the reel at an elevated position without transferring destabilizing forces to the main frame, thus maintaining both hose management convenience and system stability
