Solution Overview

Problem

Existing granite polishing machines are heavy and require oil lubrication for their gear systems, limiting their efficiency and effectiveness in polishing the edges of countertops.

Innovation Solution

A multi-wheel grinder tool utilizing a pulley system instead of a gear system, which reduces weight and eliminates the need for oil lubrication, featuring a support platform, motor, pulley system, pad drivers, square bearing housings, pad holders, and a water spraying system to maximize surface polishing area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If a gear system is used in the granite polishing machine, then the transmission of rotational motion is achieved, but the weight of the machine increases and oil lubrication is required

Engineering Contradiction:

Improvetransmission of rotational motionVSAvoidweight of the polishing machine

Core Design Contradiction:

PowerVSWeight of moving object

Solution Approach 1:

The patent replaces the gear system with a pulley system driven by a belt. The motor drives a drive pulley that transmits rotational motion through a belt to multiple driven pulleys, each connected to a polishing pad. This substitution eliminates the need for heavy gear components and oil lubrication while maintaining effective power transmission to all polishing pads.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Power

If a gear system is used in the granite polishing machine, then the transmission of rotational motion is achieved, but the need for oil lubrication increases

Engineering Contradiction:

Improvetransmission of rotational motionVSAvoidoil lubrication

Core Design Contradiction:

PowerVSLoss of substance

Solution Approach 1:

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If traditional polishing pads are used, then the edges of countertops are polished, but the polishing area is limited

Engineering Contradiction:

Improvepolishing of countertop edgesVSAvoidpolishing area

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The patent divides the polishing function into multiple independent polishing pads (at least three pads) arranged in a triangular configuration. Each pad can contact a different section of the countertop edge, allowing simultaneous polishing of multiple areas. This segmentation increases the total polishing area and improves efficiency compared to a single pad system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent arranges the polishing pads in a three-dimensional triangular configuration rather than a linear arrangement. This spatial distribution allows the pads to contact different portions of the countertop edge simultaneously, maximizing the polishing area and enabling more comprehensive edge treatment in a single operation.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

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 pulley system-based multi-wheel grinder tool minimizes weight and eliminates oil lubrication needs while maximizing the area polished by the pads, enhancing efficiency and usability in polishing granite countertops.

Implementation Method 1

a pulley system which includes four pulley wheels that are arranged horizontally linearly within the grinder housing, three idle pulleys that are staggered between each pulley wheel, a belt tension wheel that is positioned at a position that is above the four pulley wheels and that is secured to the handling surface, and a belt that operatively connects the motor pulley wheel, the four pulley wheels, the idle pulleys and the belt tension wheel

Methodology Applied

Scientific EffectFriction: Friction

Implementation Method 2

within the central channel there is a set of two spring holding cavities that run in the same direction as the central channel and that are positioned at an equal distance from each opposite support surface

Methodology Applied

Scientific EffectElasticity: Elasticity
