Problem

The current load adjustment process for bevel grinding devices is cumbersome, requiring manual reading and inputting of pressing load information from a load measuring device, leading to inefficiencies and potential errors.

Innovation Solution

A load adjusting system and method that includes a control device which acquires measurement data from a load measuring device, calculates an adjustment value based on set parameters, and controls the pressing operation of the grinding head to efficiently adjust the pressing load, reducing manual intervention and increasing accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual reading and inputting of pressing load information is performed, then measurement capability is achieved, but operation time and error rate increase

Engineering Contradiction:
Improvepressing load measurementVSAvoidadjustment work time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical process of reading and inputting load data with an automated information processing system. The control device automatically acquires measurement data from the load measuring device, calculates adjustment values, and controls the pressing operation, eliminating manual intervention entirely.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs self-adjustment by automatically acquiring its own measurement data, calculating the necessary adjustments, and executing the pressing control without external human input. The control device serves the system's own adjustment needs autonomously.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If manual reading and inputting of pressing load information is performed, then measurement capability is achieved, but operation complexity increases

Engineering Contradiction:
Improvepressing load measurementVSAvoidadjustment operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent merges the measurement device, control device, and pressing mechanism into an integrated system. The control device combines multiple functions: acquiring measurement data, calculating adjustment values, and controlling the pressing operation, simplifying the overall operation to a single automated process.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The manual operational steps are replaced by an automated information processing system that handles data acquisition, calculation, and control execution, transforming a multi-step manual process into a single automated operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If manual reading and inputting of pressing load information is performed, then measurement capability is achieved, but error rate increases

Engineering Contradiction:
Improvepressing load measurementVSAvoidadjustment accuracy
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent eliminates human reading and inputting operations by using automated data acquisition and processing. The control device directly receives measurement data from the load measuring device and processes it without human intervention, removing the source of manual errors.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system implements a closed-loop feedback mechanism where the control device continuously monitors pressing load through the load measuring device, automatically calculates adjustments based on measured values, and adjusts the pressing operation accordingly, ensuring accurate and reliable control.

Inventive Principle:
Principle #23Feedback
