Robot Brush Cleaning Assembly for Hair Entanglement Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous cleaning machines face challenges in maintaining consistent cleaning performance due to foreign substances like hair and threads getting wound around the brushes, leading to overcurrent and temperature issues, which can cause malfunction.
Innovation Solution
The autonomous cleaning machine incorporates a brush unit with first and second brush cleaning members that are inclined and arranged symmetrically to move foreign substances to the central portion, and a third brush cleaning member that elastically deforms the brushes to prevent entanglement, along with a dust collection assembly to remove these substances effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the brush unit continuously rotates to clean the floor, then cleaning productivity is improved, but foreign substances get wound around the brushes causing reliability deterioration
Solution Approach 1:
The brush cleaning unit is activated preliminarily when foreign substances are detected on the brush unit before they cause malfunction. The controller detects foreign substances and activates the brush cleaning unit to remove them, preventing overcurrent and temperature issues that would otherwise occur during continuous operation
Solution Approach 2:
The brush cleaning unit enables the brush unit to clean itself autonomously. The cleaning members contact the rotating brush to remove wound foreign substances, allowing the system to maintain reliability without external intervention while continuing its cleaning function
2Reliability
If brush cleaning members are added to remove foreign substances, then brush unit reliability is improved, but device complexity increases
Solution Approach 1:
The brush cleaning unit is integrated with the existing brush unit structure. The cleaning members are positioned to contact the brush during its rotation, merging the cleaning function with the existing rotational mechanism rather than adding separate complex systems
Solution Approach 2:
The cleaning members act as intermediaries between the brush unit and foreign substances. These members contact the brush surface to remove wound substances, providing a simple mechanical solution that bridges the gap between continuous rotation and foreign substance removal
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 ensures the autonomous cleaning machine maintains high cleaning performance by effectively removing foreign substances from the brush unit, preventing malfunctions and ensuring continuous operation.
Implementation Method 1
the first brush cleaning members may be installed such that each of the first brush cleaning members is respectively inclined in a designated direction based on a rotating direction of the brush unit so as to apply pressure to the brushes to elastically deform the brushes in the designated direction
