Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning systems for objects are cumbersome due to the weight of fluid containers on handles, leading to user fatigue and difficulty in precise guidance, and lack the ability to adjust cleaning intensity and efficiently remove dirt particles and cleaning fluid.
Innovation Solution
A system incorporating a line for carrying compressed air, a valve device to control air and fluid flow, and an outlet device that mixes compressed air and fluid for adjustable cleaning intensity, with a modular housing that can serve as a handle and integrate with vacuum cleaners for efficient dirt removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the fluid container is mounted on the handle, then the cleaning system can carry fluid, but the user's arm quickly becomes fatigued due to increased weight
Solution Approach 1:
The system separates the fluid container from the handle, placing it in a separate mobile unit (cleaning cart or vacuum cleaner). The handle only carries essential components for operation, while the fluid container resides in the mobile unit and is connected via hoses, thereby reducing handle weight while maintaining fluid availability.
Solution Approach 2:
Flexible hoses serve as intermediaries connecting the handle to the mobile unit containing the fluid container. This allows the fluid to be transported from the mobile unit to the handle without requiring the heavy container to be mounted on the handle itself, resolving the weight issue while maintaining fluid delivery capability.
2Ease of operation
If the fluid tank is disposed on the handle, then the system can deliver fluid, but it becomes difficult to precisely guide the cleaning device
Solution Approach 1:
The system divides the cleaning device into separate functional modules: a lightweight handle for precise maneuvering and a separate mobile unit containing the fluid tank. This segmentation allows the handle to remain simple and easy to guide while the fluid storage function is relocated to the mobile unit.
Solution Approach 2:
Flexible hoses act as intermediaries that provide fluid connection between the mobile unit and handle without adding structural complexity to the handle. The hoses can accommodate the movement and positioning needs of the lightweight handle, enabling precise guidance while maintaining fluid delivery capability.
3Adaptability or versatility
If compressed air and fluid are mixed in a controlled manner, then cleaning intensity can be adjusted, but the system requires multiple valves and flow control mechanisms
Solution Approach 1:
The system employs dynamic flow control where the mixing ratio of compressed air and fluid can be adjusted during operation. Multiple valves and flow control mechanisms allow users to dynamically adapt the cleaning intensity to match different soiling levels, transforming a static system into a versatile, adaptable cleaning solution.
Solution Approach 2:
The system controls cleaning intensity by changing parameters such as air-to-fluid mixing ratios, pressure levels, and flow rates through multiple valves and control mechanisms. These parameter adjustments enable the system to adapt to various cleaning requirements, from light dusting to heavy-duty cleaning tasks.
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 system reduces user fatigue by distributing weight, allows for adjustable cleaning intensity based on soiling levels, and efficiently removes dirt and fluid through the controlled mixture of compressed air and fluid, enhancing cleaning effectiveness and comfort.
Implementation Method 1
The released fluid is captured and carried along by the compressed air flow in the connecting flange and/or in the outlet device
