Magnetic Panel Cleaner With Dual-Blade Force Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices for aquarium panels are not optimally adapted to remove various types of soiling, including both easily removable and stubborn deposits, due to uniform pressing forces and contact areas of the blades.
Innovation Solution
The use of blades of different lengths with varying magnetic forces and geometries allows for adjustable pressing forces, enabling effective removal of light and obstinate soiling by employing longer and shorter blades respectively, along with a base member spaced to prevent scratching and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two blades of identical length and geometry are used, then the cleaning device has simple structure and easy manufacture, but it cannot effectively remove various types of soiling (light and stubborn deposits) simultaneously
Solution Approach 1:
The patent applies local quality by making the two blades different in length and geometry, so that each blade has different pressing force characteristics. The shorter blade exerts greater pressing force for stubborn soiling, while the longer blade exerts lesser pressing force for light soiling, allowing the device to handle various types of contamination effectively.
Solution Approach 2:
The patent implements asymmetry by using blades of unequal length and different geometries. This asymmetric configuration creates different pressing forces on the panel surface, enabling the cleaning device to address both light and stubborn deposits with a single device, thereby improving adaptability without requiring multiple separate tools.
2Adaptability or versatility
If uniform pressing force is applied by both blades, then the magnetic arrangement is simple, but it cannot provide differentiated cleaning action for light and stubborn soiling
Solution Approach 1:
The patent applies local quality by creating non-uniform pressing forces through asymmetric blade geometries and differential magnetic element arrangements. The shorter blade is configured to receive greater magnetic attraction force, creating higher pressing force localized at that blade, while the longer blade receives lesser force, enabling differentiated cleaning actions for different types of soiling.
3Object-affected harmful factors
If the base member contacts the panel directly, then the structure is simple, but it may scratch or damage the panel and seals
Solution Approach 1:
The patent introduces the two blades as intermediary elements between the base member and the panel. Instead of the base member contacting the panel directly, the blades serve as the contact interface, concentrating the cleaning action at their edges while the rounded portions of the blades prevent direct contact between the base member and the panel, thereby avoiding scratching and damage.
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 results in a flexible and efficient cleaning device capable of quickly and effectively removing diverse types of soiling from aquarium panels, including algae and coralline algae, while minimizing damage to the panel and seals.
Implementation Method 1
the control member and the cleaning member can be made to interact magnetically through the panel by means of appropriately disposed magnetic elements

AI summary
A cleaning device for cleaning the back side of a panel with a control member and a cleaning member, which is separate from the control member and which has a base member and two blades disposed thereon. The control member and the cleaning member interact magnetically through the panel, so that the cleaning member disposed on the back side of the panel can be guided along the panel while pressing the cleaning edges of both blades on the back side of the panel by means of the control member disposed in a manner corresponding to it on the front side of the panel. The two blades may be of different lengths and, by suitable geometry and arrangement of the blades or of magnetic elements, the shorter of the two blades exerts a greater pressing force on the panel with its cleaning edge than does the longer.
