Grout Removal Tool with Segmented Grinding and Vacuum
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grout removal tools are labor-intensive, inefficient, and generate significant dust and debris, particularly in large commercial settings like kitchens, due to their design limitations and inability to handle non-linear tile joints effectively.
Innovation Solution
A tool with a pair of disc-shaped grinding wheels spaced apart to cover multiple non-linear tile joints, coupled with a vacuum attachment to minimize dust and debris, allowing for simultaneous grinding and efficient removal of grout across larger areas without the need for frequent repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single grinding element is used in conventional grout removal tools, then the tool structure remains simple, but the productivity and efficiency of grout removal from large flooring areas is reduced
Solution Approach 1:
The single grinding element is divided into multiple grinding elements (first grinding element and second grinding element) mounted on the same rotating shaft. Each grinding element can independently contact and remove grout from different tile joints, effectively segmenting the grout removal function to handle multiple joints simultaneously and improve productivity without requiring multiple separate tools
Solution Approach 2:
The invention transitions from a single-point grinding approach to a multi-point grinding approach by mounting grinding elements at different axial positions on the shaft. This spatial arrangement in the axial dimension allows the tool to simultaneously engage with multiple tile joints across different locations, expanding the effective working area without increasing the tool's footprint
2Productivity
If conventional grout removal tools are used to remove grout from multiple paths, then all grout can be removed, but the tool requires frequent lifting and repositioning which reduces efficiency
Solution Approach 1:
By segmenting the grinding function into multiple elements spaced apart along the shaft, the tool can simultaneously target multiple tile joint paths without needing to lift and reposition between paths. The operator can maintain continuous contact with the flooring surface while all grinding elements work in parallel on different joints
Solution Approach 2:
The multiple grinding elements enable continuous grout removal operation without interruption for repositioning. While the tool moves along one path, the spaced-apart grinding elements can engage with multiple paths simultaneously, ensuring the useful action of grout removal continues without idle time for lifting or repositioning
3Productivity
If conventional grout removal tools are used to grind grout, then grout is removed, but considerable dust and debris are created and spread
Solution Approach 1:
A vacuum attachment is introduced as an intermediary system that works in conjunction with the grinding elements. The vacuum attachment captures dust and debris generated during grinding through suction, preventing it from being spread into the environment. This intermediary system allows the grinding function to continue while neutralizing the harmful effect of dust generation
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 tool significantly accelerates grout removal by enabling simultaneous grinding in multiple joints, reducing labor and dust generation, making it more efficient and suitable for larger commercial settings while maintaining a clean environment.
Implementation Method 1
the grinding element abrades the undesirable grout from the joint
Implementation Method 2
a slight downward force is applied onto the tool so that the grinding element abrades the undesirable grout from the joint

AI summary
A grout removal tool includes a cover shaped to define a substantially enclosed interior cavity and a grinding assembly designed to simultaneously abrade grout from multiple, non-linear tile joints. The grinding assembly includes a motor-driven shaft that is rotatably coupled to the cover by a pair of ball bearings. The grinding assembly additionally includes two or more grinding elements that are axially mounted on the shaft in a spaced apart relationship, each grinding element including at least one disc-shaped grinding wheel. A vacuum attachment is externally mounted on the cover and is in communication with the interior cavity through a plurality of circular openings formed in the cover in direct alignment with the grinding elements. One end of the vacuum attachment is preferably connected to a vacuum device that forcibly withdraws and contains debris created during the grout grinding process.
