Hard surface vacuuming device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hard surface suction devices, such as those used for cleaning window panes, often require significant operator effort due to the need to guide the device along surfaces, leading to fatigue.
Innovation Solution
The handle of the suction device is positioned below the suction unit, with the dirty liquid tank also located below, allowing the operator to support the device and reducing tilting moments, and incorporating a rechargeable battery and detachable components for improved handling and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle is positioned above or at the same level as the suction unit, then the device structure is simpler, but the operator effort and fatigue increase due to unfavorable weight distribution
Solution Approach 1:
The handle is repositioned from a horizontal or upper arrangement to a lower vertical arrangement below the suction unit. This spatial reconfiguration in the vertical dimension creates a more favorable center of gravity position, allowing the operator to better support the device weight with their hand, thereby reducing operator effort and fatigue during operation.
2Ease of operation
If the dirty liquid tank is positioned above the handle, then the liquid drainage is more effective, but the device becomes harder to handle as the tank fills with liquid
Solution Approach 1:
The dirty liquid tank is repositioned from an upper location to a lower location below the handle. This vertical repositioning changes the center of gravity dynamics, allowing the tank weight to be better supported by the operator's hand. The tank maintains its drainage functionality through the liquid outlet connection to the suction unit, while improving overall handling comfort during operation.
3Ease of operation
If the handle surrounds the dirty liquid tank, then the weight distribution is improved, but the device complexity increases
Solution Approach 1:
The handle is designed to surround and integrate with the dirty liquid tank, creating a unified structural assembly. This merging of components achieves favorable weight distribution and center of gravity positioning, allowing the operator to better support the combined weight. The integrated design improves handling comfort while maintaining structural efficiency.
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
This configuration reduces operator effort and fatigue by distributing the weight and center of gravity, allowing easier handling and operation, even as the device fills with liquid, and enables independent operation with a rechargeable battery.
Implementation Method 1
the suction unit can apply negative pressure to the separation chamber. Under the effect of the negative pressure, a suction flow is formed from the suction nozzle through the separation chamber to the suction unit
