Skid Steer Floor Grinding System with Rotating Beam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional floor grinders are limited in size due to their 'push-behind' design, leading to reduced usable cutting area and increased labor intensity for large area grinding and polishing tasks.
Innovation Solution
A motor-driven grinding wheel assembly attached to a rotating beam that moves in a circular motion, allowing for a larger polishing area and effective flattening and polishing of floors, with adjustable legs and swiveling caster wheels for improved maneuverability and counterbalances for load balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional floor grinders use a push-behind design with a round disk containing radial array of cutting disks, then the device is easy to maneuver manually, but the usable cutting area is reduced and labor intensity increases
Solution Approach 1:
The floor grinder is divided into multiple independent cutting heads (first, second, third, and fourth cutting heads) arranged around a central axis. Each cutting head can be independently positioned and adjusted, allowing the system to process large floor areas simultaneously while maintaining manageable device size through modular segmentation.
Solution Approach 2:
The invention transitions from a two-dimensional cutting surface (conventional round disk) to a three-dimensional arrangement of cutting heads positioned at different radial distances and angular positions around a central axis. This spatial distribution dramatically increases the total usable cutting area while keeping each individual cutting head within manageable size limits.
2Device complexity
If conventional floor grinders use a push-behind design, then the device structure is simple, but the labor intensity increases for large area grinding
Solution Approach 1:
Multiple cutting heads are merged into a single integrated system that operates simultaneously on different sections of the floor. The first and second cutting heads are positioned on one side of the central axis while the third and fourth cutting heads are on the opposite side, creating a balanced configuration that processes large areas in one pass, thereby reducing overall labor intensity despite increased device complexity.
Solution Approach 2:
Each cutting head is equipped with adjustable legs and swiveling caster wheels, allowing the same structural components to serve multiple functions: supporting the cutting head, enabling height adjustment, and providing maneuverability. This multi-functionality reduces the need for separate adjustment mechanisms for each cutting head, managing device complexity while enhancing productivity.
3Area of stationary object
If floor processing system uses multiple cutting heads at different radial positions, then the processing area is expanded, but the device complexity increases
Solution Approach 1:
The cutting heads are positioned asymmetrically relative to the central axis, with the first and second cutting heads at a first radial distance on one side, and the third and fourth cutting heads at a second radial distance on the opposite side. This asymmetric arrangement maximizes the processing area coverage while maintaining structural balance and managing complexity through non-uniform distribution.
Solution Approach 2:
The device incorporates counterbalances to offset the weight distribution created by having multiple cutting heads at different radial positions. The counterbalances compensate for the asymmetric mass distribution, maintaining device stability and ease of maneuverability despite the expanded processing area and increased structural 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
The system enables efficient processing of large areas with reduced labor intensity by providing a wide sweeping motion and simultaneous axial and radial processing capabilities, overcoming the limitations of conventional floor grinders.
Implementation Method 1
a motor driven, grinding wheel assembly which attaches to the end of a rotating beam which is also motor driven. The rotating beam moves the grinding wheel assembly in a circular motion providing for a large polishing area during operation.
Implementation Method 2
All concrete grinders use some sort of abrasive to grind or polish such as diamond tools or Silicon carbide. The cutting tools used for grinding most commonly are diamond grinding cup wheels, and for polishing are usually diamond polishing pads.
