Solution Overview

Problem

Existing computer numerical control apparatuses face challenges in processing workpieces that exceed their processing range, requiring manual conveyance and leading to potential workpiece deflection and discontinuous patterns.

Innovation Solution

A workpiece conveying device with first and second conveying assemblies arranged to face each other, forming a clamping portion to securely hold the workpiece, and a lifting assembly to adjust the spacing distance for adaptability to various workpiece sizes, ensuring stable and safe conveyance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the workpiece is directly placed under the processing head for processing, then the processing operation is simple, but the workpiece may deflect during conveyance causing discontinuous patterns

Engineering Contradiction:
Improveprocessing operation simplicityVSAvoidpattern continuity
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The conveying device is divided into multiple conveying assemblies (first conveying assembly and second conveying assembly) that work together to provide stable support and conveyance for the workpiece, preventing deflection while maintaining operational simplicity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The conveying device acts as an intermediary between the workpiece and the processing head, providing a stable conveyance path that prevents workpiece deflection while enabling continuous processing operations

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If manual conveyance is used for workpieces exceeding processing range, then the workpiece can be moved into position, but workpiece deflection and discontinuous patterns occur

Engineering Contradiction:
Improveworkpiece positioning capabilityVSAvoidworkpiece stability during conveyance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The conveying device features adjustable spacing between conveying assemblies that can be dynamically modified to accommodate workpieces of different sizes and lengths, while maintaining stable conveyance through controlled movement

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The conveying device is designed with universal applicability to handle workpieces of various dimensions by adjusting the spacing between conveying assemblies, providing both positioning and stable conveyance functions in one system

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Device complexity

If the spacing between conveying assemblies is fixed, then the device structure is simple, but it cannot adapt to various workpiece sizes

Engineering Contradiction:
Improveconveying device structureVSAvoidworkpiece size adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The spacing between conveying assemblies is made adjustable rather than fixed, allowing the device to adapt to different workpiece sizes while maintaining a relatively simple overall structure through controlled modification of one parameter

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The key parameter of spacing between conveying assemblies can be changed to accommodate different workpiece sizes, providing adaptability without requiring complete structural redesign for each workpiece dimension

Inventive Principle:
Principle #35Parameter changes
