Robot Cleaner Sliding Module with Detachable Mop Fixing Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robot cleaners face challenges in efficiently performing mopping operations due to issues with mop attachment and detachment, user convenience, accurate fixing of mops, and the inability to effectively remove both large and micro-scale foreign matter, leading to incomplete cleaning.
Innovation Solution
A robot cleaner design featuring a sliding module with a mop fixing unit that allows for easy attachment and detachment of mops, utilizing a friction-forming surface and guide protrusions for secure fixing, and an air channel to enhance mop performance in capturing micro-scale debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mop is strongly fixed to the robot cleaner, then the mop does not separate during mopping operation, but a large amount of time or effort is required to detach the mop
Solution Approach 1:
The robot cleaner is divided into separable modules: the main body and the sliding module with mop fixing unit. This allows the mop to be strongly fixed during operation while enabling quick detachment by separating the sliding module from the main body.
Solution Approach 2:
The mop fixing mechanism transitions from a static strong fixation to a dynamic state where the sliding module can be easily separated. The friction-forming surface provides strong fixation during operation, but the entire fixing unit can be dynamically detached by removing the sliding module.
2Ease of operation
If the replaceable mop is weakly fixed to the robot cleaner, then the mop is easy to detach, but the mop may become separated from the robot cleaner during mopping operation
Solution Approach 1:
The mop fixing system is segmented into the mop fixing unit and the sliding module. The friction-forming surface provides strong fixation between the mop and fixing unit, while the sliding module can be easily separated from the main body for quick mop replacement.
Solution Approach 2:
The sliding module acts as an intermediary between the user and the mop fixing mechanism. Users interact with the sliding module for easy detachment, while the friction-forming surface ensures reliable mop fixation during operation.
3Ease of operation
If the user overturns the entire robot cleaner to replace the mop, then the mop can be accessed, but user convenience is reduced due to the weight and complexity of the operation
Solution Approach 1:
The robot cleaner is segmented into a main body and a detachable sliding module containing the mop fixing unit. Users only need to remove the lightweight sliding module to access and replace the mop, avoiding the need to overturn the entire heavy robot cleaner.
Solution Approach 2:
The mop fixing unit is extracted from the main body and placed in a separable sliding module. This extraction allows users to access the mop by removing only the necessary component rather than the entire device.
4Speed
If air flows from the front end of the contact region between the mop and the floor, then the robot cleaner moves forward, but micro-scale foreign matter flies away without clinging to the mop
Solution Approach 1:
The air channel is designed to counteract the harmful air flow that causes micro-scale foreign matter to fly away. By introducing air flow in the opposite direction through the air channel, the system prevents foreign matter from being blown away while maintaining forward movement.
Solution Approach 2:
The air flow that initially causes micro-scale foreign matter to fly away is converted into a beneficial force. The air channel uses this air flow to blow foreign matter toward the mop, improving mopping performance while maintaining robot cleaner movement speed.
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
The design enables efficient and thorough mopping by ensuring secure mop attachment, improved user convenience, and effective removal of both large and micro-scale foreign matter, enhancing the overall cleaning performance.
Implementation Method 1
the mop fixing unit may have a friction-forming surface that provides relatively high frictional force in the state in which the mop is in contact with the friction-forming surface
