Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mop bucket systems experience significant liquid spillage due to turbulence and changing forces during movement, leading to splash hazards and inefficiencies.
Innovation Solution
A mop bucket system featuring a liquid-retaining portion with an energy-dissipation device that includes baffles and projections to break surface tension and inhibit momentum buildup, reducing wave amplification and splashing by distributing energy across a larger surface area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mop bucket is moved from one location to another, then the cleaning liquid can be transported to different areas, but the changing forces during movement cause wave amplification and splashing that results in liquid spillage
Solution Approach 1:
An energy-dissipation device is introduced as an intermediary element within the mop bucket. This device includes a baffle structure with specific geometric features (projections extending from the baffle surface) that interact with the liquid to dissipate wave energy and reduce splashing during bucket movement
Solution Approach 2:
The invention changes the physical parameters of the liquid-bucket system by introducing a baffle structure with optimized dimensions. The baffle has a height of 2-4 inches and projections with specific heights (0.5-2 inches) and spacing (1-3 inches apart) that are designed to break surface tension and dissipate wave energy at critical momentum regions
2Quantity of substance
If cleaning liquid spills onto the floor or stairway, then the liquid can be distributed across surfaces, but this creates slip-and-fall hazards and requires additional cleaning time
Solution Approach 1:
The energy-dissipation device performs preliminary anti-action by preemptively breaking wave surface tension and dissipating liquid momentum before waves can reach the bucket rim and cause spillage. The baffle structure with its projections creates turbulence and energy dissipation in advance, preventing the harmful spilling effect before it occurs
3Stability of the object's composition
If the mop bucket experiences turbulent forces at the liquid-air interface, then the liquid can be agitated for mixing, but this causes wave amplification that leads to liquid droplets exiting the bucket
Solution Approach 1:
The baffle structure is strategically positioned to affect only specific regions of the liquid. The projections on the baffle create localized turbulence and energy dissipation in the higher-momentum region (center 70% of the bucket width) while leaving other regions relatively undisturbed, thus achieving mixing without excessive wave amplification
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 effectively reduces splashing by 40% at one-quarter full capacity and 15% at one-half full capacity compared to conventional buckets, minimizing spillage and associated hazards.
Implementation Method 1
The energy-dissipation device is configured to inhibit build up of momentum of liquid in the higher-momentum region along at least a portion of the liquid-movement direction by breaking surface tension of the liquid

AI summary
A mop bucket system includes a liquid-retaining portion and an energy-dissipation device. The liquid-retaining portion is configured to retain liquid. It has a bottom wall portion, a first sidewall portion, a second sidewall portion facing the first sidewall portion, a third sidewall portion, and a fourth sidewall portion facing the third sidewall portion. The liquid-retaining portion permits retained liquid to move in a liquid-movement direction extending from the first sidewall portion toward the second sidewall portion within a higher-momentum region having a width that is approximately 70% of a distance between the third sidewall portion and the fourth sidewall portion. The energy-dissipation device is disposed within the liquid-retaining portion and extends into the higher-momentum region. The energy-dissipation device being configured to inhibit build up of momentum of liquid in the higher-momentum region along at least a portion of the liquid-movement direction by breaking surface tension of the liquid.
