Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Car washing methods often result in potential paint damage from abrasive action due to dirt and residue remaining on the vehicle's surface, and existing water filtration systems are expensive and inefficient in removing particles.
Innovation Solution
A cleaning device with a porous body containing a dispensing reservoir and a perforated fluid supply conduit, where the dispensing reservoir and fluid supply conduit are not directly fluidly coupled, allowing for controlled flow of cleaning solution and water through strategically arranged openings and perforations, optimizing the washing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water is used to wet the vehicle surface before applying cleaning solution, then dirt and residue can be removed, but large quantities of water are consumed
Solution Approach 1:
The dispensing reservoir is nested within the porous body, with the reservoir containing cleaning solution and the porous body absorbing and distributing water. This nested structure allows both water and cleaning solution to be delivered simultaneously through the same cleaning implement, reducing the need for separate wetting and soaping steps, thereby reducing water consumption while maintaining effective dirt removal
Solution Approach 2:
The patent combines the water delivery system (perforated conduit) and cleaning solution delivery system (dispensing reservoir with openings) into a single integrated cleaning device. This merging allows water and cleaning solution to be applied simultaneously through the same porous body, eliminating the need for separate wetting and soaping operations, thus reducing overall water usage while maintaining cleaning effectiveness
2Object-affected harmful factors
If filtering devices are used to remove particles from water supply, then paint damage from abrasive particles is prevented, but the filtering devices are expensive
Solution Approach 1:
The patent uses a disposable or replaceable porous body that can be discarded after use, eliminating the need for expensive reusable filtration systems. The porous body itself acts as a simple, low-cost filter that removes particles from both water and cleaning solution, providing adequate protection against paint damage without the complexity and cost of sophisticated filtration devices
Solution Approach 2:
The patent employs a porous body made of porous material that naturally filters particles from water and cleaning solution as they pass through its structure. This porous material provides effective particle removal protection for the vehicle paint at minimal cost and complexity, replacing the need for expensive mechanical filtration systems while maintaining adequate protection against abrasive damage
3Reliability
If a soapy sponge is used to wipe off dirt and residue, then cleaning is performed, but paint coating could be scratched or damaged from abrasive action
Solution Approach 1:
The patent delivers water through the porous body before or simultaneously with the cleaning solution to pre-wet and loosen dirt and residue on the vehicle surface. This preliminary wetting action softens and suspends particles, making them less abrasive when subsequently removed by the soapy sponge, thereby reducing the risk of paint scratching while maintaining cleaning effectiveness
Solution Approach 2:
The patent uses water as an intermediary substance delivered through the porous body to mediate between the dirt/residue and the soapy sponge. The water suspends and removes loose particles before the soapy sponge contacts the surface, creating a protective layer that reduces direct abrasive contact between embedded particles and the paint coating, thus preventing scratches while maintaining cleaning effectiveness

AI summary
A cleaning device includes a porous body and a dispensing reservoir disposed within the porous body. The dispensing reservoir has at least one opening being disposed at a predetermined location along a length of the dispensing reservoir such that a rate at which the solution flows into the porous body varies based specific orientations of the porous body. A perforated fluid supply conduit is also disposed within the porous body and extends alongside the dispensing reservoir, the perforated fluid conduit having a plurality of perforations. The dispensing reservoir and the perforated fluid supply conduit are not directly fluidly coupled.
