Solution Overview

Problem

The production of circular saw disks requires manual handling and processing to ensure planarity, which is time-consuming, operator-dependent, and poses safety risks due to the weight and size of the disks, leading to inefficiencies and increased costs.

Innovation Solution

A machine tool with a spindle unit, capacitive sensor assembly, and hammer assembly that automatically detects and corrects planarity discrepancies on saw disks by using a database to determine the necessary force and number of hammer blows for precise and repeatable planarization, allowing for self-learning and autonomous operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual processing is used to ensure planarity, then planarity precision can be maintained within tolerances, but processing time increases and operator dependency increases

Engineering Contradiction:
Improveplanarity precisionVSAvoidprocessing speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent replaces the manual mechanical system with an automated system comprising a sensor assembly that optically detects planarity deviations and a hammer assembly that automatically strikes corrective areas. The processor controls the hammer assembly based on sensor data, eliminating manual intervention while maintaining planarity precision within tolerances and significantly improving processing speed.

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

Solution Approach 2:

The machine tool performs self-correction by using the sensor assembly to detect planarity issues and the hammer assembly to automatically strike the necessary corrective blows without operator intervention. The system serves itself by autonomously identifying and correcting deviations, reducing both processing time and operator dependency while maintaining precision.

Inventive Principle:
Principle #25Self-service

2Manufacturing precision

If manual hammering is used to correct planarity deviations, then corrective force can be applied precisely, but operator skill dependency increases and processing becomes slower

Engineering Contradiction:
Improveplanarity correction precisionVSAvoidoperator skill requirement
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The sensor assembly continuously monitors planarity deviations and provides feedback to the processor. The processor then controls the hammer assembly to strike corrective areas with precise force and positioning. This closed-loop feedback system eliminates the need for operator skill while maintaining high correction precision, as the system automatically adjusts based on real-time sensor data.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If larger and heavier disks are processed, then market demands are met, but safety risks increase and handling difficulty increases

Engineering Contradiction:
Improvedisk size capacityVSAvoidsafety risks
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual handling and processing with an automated system where the sensor assembly scans the disk surface and the hammer assembly applies corrective forces. This automation eliminates the need for operators to physically handle large, heavy disks, thereby maintaining the ability to process oversized disks while significantly reducing safety risks and handling difficulties.

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