Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor scrubbers require manual disassembly or wiping for cleaning, which is inconvenient and troublesome for users.
Innovation Solution
A floor scrubber with a self-cleaning device that includes a barrel with a wiper member and a ratchet mechanism, allowing the scrubbing disc to be automatically cleaned and dried by rotating and using a water supply system to remove dirt and water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual wiping or disassembly is used to clean the scrubbing disc, then the cleaning process becomes troublesome and inconvenient, but the structure remains simple
Solution Approach 1:
The floor scrubber automatically cleans itself by rotating the scrubbing disc against a wiper member during the return stroke, eliminating the need for manual disassembly or wiping. The system uses its own operational motion to perform the cleaning function, making the device serve itself.
Solution Approach 2:
The wiper member is positioned to contact the scrubbing disc only during the return stroke when the disc rotates in a specific direction. The dynamic positioning allows the wiper to engage with the scrubbing disc surface during rotation, enabling automatic cleaning without interfering with the forward scrubbing operation.
2Productivity
If the scrubbing disc is designed to rotate for cleaning, then cleaning efficiency improves, but the device requires additional components like wiper members and support structures
Solution Approach 1:
The cleaning function is merged with the existing return stroke motion of the scrubbing disc. The wiper member is integrated into the housing structure, and the cleaning action occurs simultaneously with the disc's rotational movement during the return stroke, combining two functions into one operational cycle.
Solution Approach 2:
The scrubbing disc serves dual functions: it scrubs the floor during the forward stroke and enables self-cleaning during the return stroke through rotation against the wiper member. This multi-functionality increases productivity without requiring separate dedicated cleaning mechanisms.
3Ease of operation
If automatic self-cleaning is implemented, then user convenience is significantly improved, but the device structure becomes more complex with additional mechanisms
Solution Approach 1:
The system automatically cleans the scrubbing disc using its own operational motion. The user simply operates the floor scrubber as normal, and the self-cleaning function activates during the return stroke without requiring any additional user actions or interventions.
Solution Approach 2:
The wiper member is dynamically positioned to contact the rotating scrubbing disc during the return stroke. The cleaning mechanism utilizes the dynamic rotation of the disc rather than requiring complex automated positioning systems, reducing overall mechanism complexity while achieving automatic cleaning.
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
Enables convenient and rapid cleaning of the scrubbing disc, eliminating the need for manual disassembly and improving the cleaning process by using a rotating wiper member and water supply system.
Implementation Method 1
the wiper member abuts against the scrubbing disc; and when the scrubbing disc rotates or the wiper member moves, water and/or dirt on the scrubbing disc are/is wiped off by the wiper member
Implementation Method 2
the self-cleaning device further comprises a ratchet mechanism used for realizing unidirectional rotation of the roller

AI summary
A floor scrubber and a self-cleaning device matched with the same are disclosed. The floor scrubber comprises a housing connected to a handle. A motor is arranged in the housing. A scrubbing disc is arranged below the housing and is driven by the motor to rotate. The self-cleaning device comprises a barrel connected to a support member used for supporting the floor scrubber. A wiper member is arranged in the barrel. When the floor scrubber is placed in the barrel to be dried, the support member supports the floor scrubber, and the wiper member abuts against the scrubbing disc; and when the scrubbing disc rotates or the wiper member moves, water and/or dirt on the scrubbing disc are/is wiped off by the wiper member.
