Integrated Hose Reel Structure for Single-User Drain Pipe Clearing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flexible hose reels for unclogging drain pipes require two people to operate due to the need for manual RPM control and stability issues during single-user operations, making them inefficient and costly.
Innovation Solution
A hose reel design with a cylindrical basket, rotating disk, and adjustable base member, equipped with a torque impact wrench and remote control system, allowing for remote RPM control and single-user operation by integrating a controller and remote control for the torque impact wrench.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotating device is mounted on an existing flexible hose reel and protrudes from the reel, then the hose reel can be used for drain pipe clearing, but it becomes inconvenient to move and dispose the hose reel while the hose reel is oriented in one direction
Solution Approach 1:
The rotating device is integrated into the hose reel such that it is recessed within the reel body rather than protruding outward. The rotating disk and torque impact wrench are positioned inside the reel's housing, allowing the entire unit to be moved and disposed of conveniently in any orientation without the protruding structure interfering with handling or storage.
2Productivity
If manual RPM control is required during operation, then the rotating device can be operated, but two people are needed to work together, resulting in increased labor costs
Solution Approach 1:
The torque impact wrench is equipped with a built-in RPM control mechanism that automatically regulates the rotational speed of the flexible cord. This self-regulating feature eliminates the need for manual RPM control by a second operator, allowing a single user to operate the drain pipe clearing device independently while maintaining optimal operational speed throughout the process.
3Device complexity
If the hose reel is oriented in one direction with the rotating device protruding, then the structure is simplified, but it is inconvenient to move and dispose the hose reel
Solution Approach 1:
The hose reel is designed with a compact, integrated structure where the rotating device is recessed within the reel body rather than fixed in a protruding orientation. This dynamic design allows the hose reel to be easily moved and disposed of in any direction without structural constraints, improving mobility while maintaining a simplified overall form factor.
