Multi-disc Grinding Tool for Large Area Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface grinding tools with standard-sized grinding discs and sandpaper are inefficient and costly for large area grinding operations, as they require specialized and expensive larger discs and sandpaper with limited material and specification options.
Innovation Solution
A machine tool with a tool body, rotary bracket, and multiple grinding portions of equal size and weight, driven by a spindle to form a larger grinding plane, allowing for higher speed and efficiency by using smaller grinding discs that rotate synchronously to cover a larger area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If conventional standard-sized grinding discs and sandpaper are used, then the machine tool can operate with readily available and affordable materials, but the grinding area is limited and operation speed is slower
Solution Approach 1:
The invention divides a single large grinding disc into multiple smaller grinding discs (typically 3-5 discs) arranged in a circular pattern. Each small disc rotates independently but synchronously, collectively forming a large effective grinding area. This segmentation allows the use of standard-sized discs while achieving the productivity of a large-area grinder.
2Area of moving object
If larger specifications grinding discs and sandpaper are used, then the grinding area increases and efficiency improves, but the materials are difficult to acquire and expensive
Solution Approach 1:
Instead of requiring one large expensive grinding disc, the system uses multiple small standard-sized discs that are commercially available and affordable. The segmented approach transforms a material availability problem into a solution where off-the-shelf components are assembled into a high-performance system.
Solution Approach 2:
Multiple independent small grinding discs are merged into a single functional unit that operates as one large grinding surface. The combining of several standard discs creates an effective grinding area equivalent to or exceeding that of a single large disc, while maintaining material availability and cost-effectiveness.
3Area of moving object
If a single large grinding disc is used, then the grinding area is sufficient for large area operations, but the structure becomes complex and costly
Solution Approach 1:
The complex single large disc structure is segmented into multiple simple small discs. Each small disc has a straightforward mounting structure with a central hole for the spindle, eliminating the need for complex large-diameter disc constructions while achieving the same effective grinding area.
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 machine tool achieves higher grinding efficiency and speed by forming a balanced grinding plane with multiple smaller grinding discs, increasing the grinding area and reducing costs by utilizing standard-sized sandpaper, while maintaining balanced operation and effective dust management.
Implementation Method 1
a driving motor and a spindle driven by the driving motor to spin axially
Implementation Method 2
The grinding portions have grinding zones at the same horizontal level and are driven by the rotary bracket to rotate synchronously therewith to jointly form a grinding plane

AI summary
A machine tool providing a large grinding area includes a tool body, a rotary bracket driven by the tool body and a plurality of grinding portions coupled to the rotary bracket. The tool body includes a driving motor and a spindle driven by the driving motor to spin axially. The rotary bracket is coupled to and driven by the spindle to rotate and includes a plurality of connecting portions equally spaced from each other on the circumference formed by rotation of the rotary bracket. The grinding portions are coupled with the connecting portions and have grinding zones at the same horizontal level and are driven by the rotary bracket to rotate synchronously therewith to jointly form a grinding plane. Thereby a larger grinding area can be achieved through smaller grinding discs.
