Remote-Controlled Floor Surfacing Head Drive for Stable Grinding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor surfacing machines, particularly planetary-type machines, face challenges with stability and control when operated remotely, as they require steady pace and precise navigation to avoid uneven surfaces and obstacles, and operators must manually propel the machines, leading to fatigue and potential for uneven results.
Innovation Solution
A floor surfacing machine design featuring independently operable planetary and satellite heads, driven by separate motors, with a remote control system allowing for independent control of each wheel, enabling oscillating movement of the planetary head between leftmost and rightmost positions for enhanced stability and control, and a wider surfacing path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator manually propels the floor surfacing machine, then the machine can be controlled and steered, but the operator experiences fatigue and it is difficult to maintain a steady pace
Solution Approach 1:
The floor surfacing machine propels itself using a first motor and planetary head mechanism, eliminating the need for manual propulsion by the operator. The machine serves itself by generating its own driving force through the interaction between the planetary head and the floor surface, allowing the operator to focus solely on steering and monitoring without physical exertion.
Solution Approach 2:
The manual mechanical propulsion system is replaced with an automated motor-driven system. The first motor converts electrical energy to mechanical rotation of the planetary head, which then propels the machine forward through friction with the floor surface, substituting human physical effort with an automated electromechanical system.
2Ease of operation
If the machine is remotely controlled, then the operator can monitor the grinding result, but the machine requires very steady pace without uncontrolled deviations
Solution Approach 1:
The control system monitors the operating conditions and adjusts the propulsion force accordingly to maintain steady pace. The first control unit receives signals from the remote control panel and automatically regulates the first motor's output to compensate for variations in frictional forces, ensuring consistent forward motion without uncontrolled deviations.
Solution Approach 2:
The machine autonomously maintains its propulsion characteristics through the motor-controlled planetary head system. The independently operable planetary head automatically adjusts its rotation to provide consistent propulsive force, enabling the machine to maintain steady pace without requiring continuous manual intervention for pace regulation.
3Device complexity
If the planetary head and satellite surfacing heads are driven by a single motor, then the structure is simpler, but the control and stability are reduced
Solution Approach 1:
The single motor system is segmented into two independent motors: a first motor for propelling the planetary head and a second motor for driving the satellite surfacing heads. This segmentation allows independent control of propulsion and surfacing functions, enabling separate optimization of each function's parameters and improving overall control stability.
Solution Approach 2:
The system transitions from a static coupled drive mechanism to a dynamic independently controllable system. The first and second motors can operate at different speeds and torques independently, allowing the planetary head and satellite heads to be optimized for their respective functions while maintaining stable and reliable control throughout operation.
