Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional concrete grinders are limited in their ability to grind concrete surfaces close to walls, requiring labor-intensive hand grinding and resulting in visible boundaries between machine and hand-grinded areas, which increases costs and affects the uniformity of the finish.
Innovation Solution
A grinding machine with a head assembly and tooling plate that can be displaced orthogonally to the rotational axis, allowing for efficient grinding up to the wall surface, eliminating the need for hand grinding and improving visual blending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional tooling is used with segments mounted close together, then the tooling structure is compact, but the removed stock material cannot be efficiently swept away
Solution Approach 1:
The tooling is divided into multiple segments that are spaced apart from each other in the circumferential direction. This segmentation creates radial gaps between segments that allow removed stock material to be swept away by radial centrifugal forces during rotation, improving the efficiency of material removal without requiring complex additional mechanisms.
2Adaptability or versatility
If the tooling plate cannot be displaced orthogonally to the rotational axis, then the structure is simpler, but grinding close to walls is not possible
Solution Approach 1:
The tooling plate is designed with the capability to be displaced orthogonally to the rotational axis, transforming a static structure into a dynamic one. This displacement capability allows the grinding machine to adapt to different working conditions, specifically enabling grinding operations close to walls while maintaining a relatively simple overall structure through controlled movement rather than complex mechanical arrangements.
3Ease of operation
If hand grinding is used to finish areas close to walls, then the machine can maintain a simple structure, but labor costs increase and visible boundaries appear
Solution Approach 1:
The invention combines the capabilities of machine grinding and hand grinding into a single automated system. By enabling the tooling plate to be displaced orthogonally to the rotational axis, the machine can perform both bulk grinding and precision edge grinding close to walls, eliminating the need for separate hand grinding operations and achieving uniform finishes without visible boundaries.
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 solution reduces labor and costs by enabling efficient grinding close to walls, ensuring a seamless and uniform finish without the need for hand grinding, thus enhancing the quality and consistency of concrete surface treatment.
Implementation Method 1
subsequent circumferentially-spaced tooling segments could sweep away removed stock material in the circumferential direction. Additionally, the inventor recognized that the improved tooling would advantageously provide a radial gap based on the circumferential spacing between the segments in the direction 1004, which would provide an efficient means for sweeping away removed stock material due to radial centrifugal forces during the use of the tooling along the surface.

AI summary
Tooling is provided for mounting to a tooling plate to remove stock material from a surface based on rotation of the tooling plate about an axis. The tooling includes a backing plate and a plurality of segments. Each segment includes a bond and diamonds. The plurality of segments are secured to the backing plate such that a spacing is provided between the plurality of segments in a circumferential direction defined by an arc from a first side to a second side of the backing plate and/or a radial direction orthogonal to the circumferential direction. A method is also provided for removing stock material from a surface using the tooling.
