Solution Overview

Problem

Current metal sheet machining systems require a fixed schedule for workpiece transfer and are limited to processing one workpiece at a time, necessitating reprogramming and mechanical adaptation for each workpiece, which is inefficient and labor-intensive.

Innovation Solution

A loading device with driven rollers and positioning elements that allow flexible placement and transportation of workpieces, enabling simultaneous supply and removal of metal sheets from any point, optimizing the use of machine space and reducing operator intervention through precise positioning and automated feeding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a fixed schedule for workpiece transfer is used, then efficient transport within the machine is achieved, but the machine can only process one defined workpiece at a time and requires reprogramming for other workpieces

Engineering Contradiction:
Improveprocessing capacityVSAvoidworkpiece flexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making the positioning elements movable rather than fixed. The positioning elements can be repositioned along the transport area to accommodate different workpiece sizes and types, allowing the system to adapt dynamically to various machining requirements while maintaining automated transport efficiency

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements universality through a standardized transport area with adjustable positioning elements that can handle multiple workpiece types. The same transport infrastructure serves both single-workpiece precision machining and multi-workpiece batch processing, eliminating the need for separate systems

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

2Ease of operation

If manual or semi-automatic loading is used, then operator control is maintained, but labor-intensive operation and precise placement requirements reduce efficiency

Engineering Contradiction:
Improveoperator controlVSAvoidloading efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent applies self-service by enabling the system to automatically transport and position workpieces without continuous operator intervention. The automated transport area moves workpieces between machining stations, and positioning elements automatically adjust to place workpieces correctly, reducing manual labor while maintaining operational control

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces an automated transport area as an intermediary between manual loading and machining operations. This intermediary system handles the repetitive tasks of transporting and positioning workpieces, allowing operators to focus on higher-value tasks while maintaining oversight of the automated process

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If mechanical adaptation is required for each workpiece, then precise machining is achieved, but reprogramming and mechanical adjustment increase setup time

Engineering Contradiction:
Improvemachining accuracyVSAvoidsetup time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent applies dynamics by replacing fixed mechanical adaptations with movable positioning elements that can be quickly repositioned. This allows the system to maintain machining precision for different workpiece types without requiring time-consuming mechanical reconfiguration or reprogramming of the entire system

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements preliminary action by pre-configuring the transport area with multiple positioning elements that are ready to accommodate different workpiece types. When a workpiece change is needed, the system can quickly switch between pre-positioned elements rather than performing complex mechanical adaptations from scratch

Inventive Principle:
Principle #10Preliminary action
