Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wet robot cleaners without suction structures are prone to contamination by foreign substances, which reduces their cleaning effectiveness and can lead to additional surface contamination.
Innovation Solution
Incorporation of an electrostatic adsorption pad and a foreign substance barrier wall in the wet cleaning robot to prevent foreign substances from adhering to the rotational wet pad, using electrostatic adsorption to trap and contain foreign substances before they reach the pad.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a wet robot cleaner is designed without a suction structure to maintain its main function of wet cleaning, then the device complexity is reduced and the wet cleaning function is preserved, but the wet pad becomes easily polluted by foreign substances on the surface
Solution Approach 1:
The cleaning system is divided into two functional modules: a wet cleaning module with the rotational wet pad and a contamination prevention module with the electrostatic adsorption pad. This segmentation allows each module to perform its specific function independently, resolving the contradiction by adding contamination prevention capability without integrating a full suction structure
Solution Approach 2:
The electrostatic adsorption pad acts as an intermediary component between the surface and the wet pad. It intercepts foreign substances through electrostatic attraction before they can reach the wet pad, preventing contamination while maintaining the simple wet cleaning structure
2Productivity
If the wet pad contacts the surface directly to perform wet cleaning, then the cleaning function is effective, but foreign substances stick to the wet pad reducing cleaning time and area
Solution Approach 1:
The electrostatic adsorption pad performs preliminary action by capturing foreign substances on the surface before they can reach the wet pad. This preliminary contamination prevention extends the effective cleaning time and area of the wet pad without affecting its wet cleaning performance
3Duration of action of stationary object
If the wet pad is used continuously without contamination prevention, then the device operates continuously, but additional contamination of the surface occurs due to the contaminated wet pad
Solution Approach 1:
The electrostatic adsorption pad converts the harmful effect of foreign substances on the surface into a beneficial function by actively attracting and trapping them. This prevents the wet pad from becoming contaminated and subsequently re-contaminating the surface, enabling continuous operation without harmful side effects

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
