Integrated High-Pressure Cleaning Device With Valve Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-pressure cleaning devices suffer from insufficient rigidity in the connection between the brush and the water gun, leading to wobbling and low efficiency in cleaning, especially in extensive areas like roads and parks. Additionally, these devices often incorporate gasoline engines, causing vibration, noise, and pollution, and require users to bear the weight of both the cleaning water gun and the floor brush, resulting in user fatigue.
Innovation Solution
A high-pressure cleaning device is designed with a carrier that integrates a power unit, a valve assembly, a high-pressure water gun, and a floor brush. The valve assembly allows for switchable positions to control the flow of water, and the device includes a DC motor pump or an internal combustion engine driven pump, reducing user fatigue by allowing the user to push the carrier without bearing the weight of the cleaning equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user holds the water gun and pushes the floor brush along the road, then the cleaning function is achieved, but the connection rigidity is insufficient causing wobbling and user fatigue
Solution Approach 1:
The patent combines the water gun and floor brush into an integrated cleaning device where the brush is mounted on the gun rod through a quick-connect fitting. This merging eliminates the separate handling of two tools and provides a rigid connection structure that prevents wobbling at the interface while maintaining cleaning effectiveness.
2Ease of operation
If the user holds the water gun and pushes the floor brush, then cleaning is performed, but the user has to bear the full weight resulting in high physical demands
Solution Approach 1:
The patent introduces a support stand with adjustable height and angle that can bear the weight of the cleaning device. The support stand includes a support rod connected to the gun body, allowing the device to be stabilized on the ground or a surface, thereby counterbalancing the weight and reducing the physical burden on the user during operation.
3Adaptability or versatility
If the cleaning water gun is designed to be short for flexibility, then user flexibility is improved, but the user has to bend over during operation compromising comfort
Solution Approach 1:
The patent implements an adjustable gun rod length mechanism that allows the user to extend or retract the rod according to the cleaning requirements. The gun rod includes a telescopic structure with locking mechanisms, enabling dynamic adjustment of the rod length to reach different areas while maintaining ergonomic operation height and user comfort.
4Ease of manufacture
If a quick-connect fitting is used to attach the floor brush, then the connection is easy to assemble, but the rigidity is insufficient leading to wobbling
Solution Approach 1:
The quick-connect fitting is designed with segmented components including a male connector on the brush and a female connector on the gun rod, allowing easy assembly and disassembly. The segmentation enables simple attachment while incorporating internal rigidizing structures such as engagement ribs and locking features that prevent wobbling and ensure stable connection during 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 integrated design of the high-pressure cleaning device reduces user workload and improves comfort by allowing the user to push the carrier without bearing the weight of the cleaning equipment, enhancing efficiency and adaptability for large-scale cleaning tasks.
Implementation Method 1
The power unit includes a pump. The valve assembly includes a liquid inlet, a first liquid outlet and a second liquid outlet. The liquid inlet is in communication with an outlet of the pump.
Implementation Method 2
The valve assembly is configured to be switchable between at least two of the following positions: position one and position two. In position one, the liquid inlet is in communication with the first liquid outlet, and the liquid inlet is disconnected from the second liquid outlet.
