Robot Cleaner Wheel Rim Guard Against Wire Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robot cleaners often entangle wires or lines dragged on the floor, causing them to be wound around the wheels, which hinders the cleaning process as the wheels become difficult to roll.
Innovation Solution
The integration of wire winding prevention members, such as torsion springs, at the lower side of the robot cleaner, with one end extending to the wheel rim and having a guide slit, prevents wires from being entangled by maintaining contact with the rim and applying pressure to prevent winding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the robot cleaner travels with wheels rolled on the floor, then the robot cleaner can move and perform cleaning, but wires or lines dragged on the floor become entangled in the wheel and are wound into the main body
Solution Approach 1:
A wire winding prevention member is introduced as an intermediary element between the wheel and the wire. This member extends from the lower surface of the main body to contact the rim of the wheel, creating a barrier that prevents wires from being entangled in the wheel while allowing the wheel to roll freely for mobility.
Solution Approach 2:
The wire winding prevention member is positioned in advance to intercept wires before they can be entangled in the wheel. By extending to contact the wheel rim and creating a guide slit structure, the system proactively prevents wire entanglement before it occurs during the robot's movement.
2Object-affected harmful factors
If wire winding prevention members are added to prevent wire entanglement, then wire entanglement is prevented, but the device complexity increases
Solution Approach 1:
The wire winding prevention member utilizes a flexible structure with a guide slit that can bend and conform to the wheel rim. This thin, flexible design provides effective wire prevention while maintaining a simple, lightweight construction that does not significantly increase device complexity.
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 effectively prevents wires from being wound into the robot cleaner, ensuring smooth operation and continued mobility during cleaning.
Implementation Method 1
The one end of the wire winding prevention member may have elasticity toward the center of the rotation shaft of the wheel in a contact state with the rim of the wheel. The wire winding prevention member may be a torsion spring.

AI summary
A robot cleaner includes wheels mounted at a lower side of a main body of the robot cleaner to allow for traveling of the main body, and wire winding prevention members mounted at the lower side of the main body, each wire winding prevention member having one end extending to be contactable with a rim of the corresponding wheel. The wire winding prevention member is preferably a torsion spring.
