Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning devices face challenges in controlling the amount of water on the floor, leading to inconsistent cleaning performance and potential floor damage, due to issues with water distribution systems that are prone to clogging and dependent on user variables such as force and speed.
Innovation Solution
A closed liquid distribution system where the cleaning cloth acts as a wick, using capillary forces to absorb and distribute water from a reservoir, maintaining consistent wetness levels independent of user speed and reducing clogging risks by using larger holes and a replaceable cloth system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If small holes are used in the liquid distribution system, then liquid distribution precision is improved, but the holes become clogged with dirt or residue
Solution Approach 1:
The patent uses a porous distribution plate with controlled pore sizes that balance liquid distribution precision and clogging resistance. The porous structure allows consistent liquid flow while the pore design prevents accumulation of dirt and residue, resolving the contradiction between precision and reliability.
Solution Approach 2:
The patent optimizes the pore size parameter of the distribution plate to a specific range that simultaneously achieves precise liquid distribution and resistance to clogging. By carefully selecting and adjusting this critical parameter, both requirements are satisfied without compromise.
2Manufacturing precision
If electric pumps are used for liquid distribution, then liquid distribution control is improved, but the system becomes vulnerable to pollution and clogging
Solution Approach 1:
The patent replaces electric pumps with a passive liquid distribution system based on capillary action and gravity. This mechanical substitution eliminates vulnerable electric components that are sensitive to pollution and chemical damage, while maintaining controlled liquid distribution through carefully designed porous structures and flow channels.
Solution Approach 2:
The liquid distribution system operates autonomously using capillary forces and gravity without requiring external power sources. The porous distribution plate and flow channels self-regulate liquid flow, eliminating the need for electric pumps that are susceptible to clogging and chemical degradation.
3Manufacturing precision
If pre-wetted cloths are used, then water amount control is improved, but the surface area that can be cleaned is very limited
Solution Approach 1:
The patent incorporates a liquid reservoir that pre-stores cleaning solution, allowing the system to maintain controlled water distribution over extended periods. This preliminary preparation of liquid supply enables continuous operation across large surface areas while maintaining precise water amount control through the porous distribution system.
Solution Approach 2:
The patent divides the liquid distribution system into multiple components: a reservoir for liquid storage, a porous distribution plate for controlled dispensing, and multiple flow channels. This segmentation allows the system to maintain precise water control while extending the cleaning capability to large surface areas through continuous liquid supply.
4Adaptability or versatility
If bucket and mop system is used, then adaptability is improved, but the amount of water on the floor is difficult to control
Solution Approach 1:
The patent incorporates feedback mechanisms where the porous distribution plate and reservoir system automatically regulate liquid flow based on saturation levels and capillary pressure. This self-regulating feedback control maintains consistent water distribution without requiring user intervention, resolving the contradiction between user adaptability and precise water control.
Solution Approach 2:
The liquid distribution system performs self-regulation through capillary action and gravity-driven flow control. The porous structure automatically adjusts liquid distribution based on demand, eliminating the need for manual wringing and pressure control by the user, thus achieving both adaptability and precision.
