Solution Overview

Problem

Grinding devices face inefficiencies due to the time-consuming and costly process of exchanging grinding media, which can lead to premature or unnecessary replacement, affecting the quality of the grinding result.

Innovation Solution

A method that uses data collection and processing to monitor the condition of the grinding medium by recording actual data, comparing it to target data, and determining the optimal time for replacement, allowing for automatic adjustment of grinding parameters to maintain desired results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the grinding medium is exchanged frequently to maintain grinding quality, then the grinding result quality is improved, but the time loss and cost increase due to frequent exchanges

Engineering Contradiction:

Improvegrinding result qualityVSAvoidtime loss due to exchange

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent implements a feedback mechanism where actual data from the grinding medium (such as vibration, temperature, or performance metrics) is continuously monitored and compared against target data. This feedback loop enables determination of the optimal exchange time based on actual condition rather than fixed schedules, preventing both premature and delayed exchanges that would otherwise cause time loss or quality degradation

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary monitoring and analysis of grinding medium condition data to predict when exchange will be necessary. By detecting wear patterns and performance degradation trends before critical failure occurs, the system allows for planned exchanges during optimal moments rather than reactive exchanges that disrupt production

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If the grinding medium is exchanged based on predetermined cycles to simplify operation, then the ease of operation is improved, but the manufacturing precision deteriorates due to premature or unnecessary replacement

Engineering Contradiction:

Improveease of exchange operationVSAvoidgrinding result quality

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The grinding medium monitoring system operates autonomously, automatically collecting data, comparing it with target values, and determining exchange timing without human intervention. This self-service capability eliminates the need for operator judgment while maintaining precise control over grinding medium performance, thereby preserving manufacturing precision while simplifying operation

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual assessment and decision-making processes with an automated electronic system that monitors grinding medium conditions and determines exchange timing. This substitution of mechanical/operator-based systems with electronic automation maintains precision while improving ease of operation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Loss of energy

If the grinding medium is used for extended periods to reduce costs, then the cost efficiency is improved, but the manufacturing precision deteriorates due to excessive wear

Engineering Contradiction:

Improvecost efficiencyVSAvoidgrinding result quality

Core Design Contradiction:

Loss of energyVSManufacturing precision

Solution Approach 1:

The continuous feedback mechanism monitors actual grinding medium performance and compares it against target thresholds. This enables extension of grinding medium life until the optimal exchange point is reached, preventing premature replacement that would waste resources while ensuring quality is maintained by detecting degradation trends before they cause defects

Inventive Principle:

Principle #23Feedback

AI summary

A method for operating a grinding device includes grinding of a surface of the workpiece with at least one grinding medium. Actual data is recorded on a data collection device during grinding with the at least one grinding medium. The actual data is then compared with target data stored in an electronic memory in an electronic data processing device. From this comparison, a determination is made of the exchange time at which the at least one grinding medium is to be changed.
