Solution Overview

Problem

Existing machining devices are limited by serial processing of workpieces, which reduces their effectiveness in machining operations.

Innovation Solution

A workpiece feeding device with a conveying system that allows multiple workpieces to be placed simultaneously in a defined position, enabling them to be fed to a workpiece table individually or in batches, thereby increasing processing efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If workpieces are fed into the machining device one at a time in serial order, then the machining device can process each workpiece individually with proper positioning and control, but the overall productivity and effectiveness of the machining operation is fundamentally limited

Engineering Contradiction:
Improvemachining effectivenessVSAvoidworkpiece feeding system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The workpiece feeding device is segmented into multiple independent conveying paths (first conveying device for long workpieces, second conveying device for short workpieces) that can operate simultaneously. Each conveying path is equipped with its own stop elements and positioning mechanisms, allowing parallel processing of different workpiece types without interference, thus resolving the contradiction between productivity improvement and system complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from single-file serial feeding to multi-dimensional parallel feeding by arranging workpieces in both longitudinal and transverse directions on the workpiece table. Multiple workpieces can be positioned at different locations (first, second, third, fourth positions) simultaneously, converting the time-based serial process into a space-based parallel process, thereby dramatically improving productivity without proportionally increasing complexity

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If multiple workpieces are positioned simultaneously on the workpiece table, then processing efficiency is enhanced through parallel operations, but the complexity of positioning and controlling multiple workpieces increases

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidworkpiece positioning and control
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The stop elements are designed with multi-functionality to handle different workpiece types and positions. The same stop element structure can constrain workpieces in various positions (first through fourth positions) and accommodate both long and short workpieces by adjusting the positioning of individual stop elements. This universal design simplifies operation while enabling complex multi-workpiece positioning

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

Solution Approach 2:

The conveying devices are equipped with automatic stop elements that can be adjusted to different positions to accommodate various workpiece lengths and types. The system provides self-service positioning where the stop elements automatically constrain workpieces at appropriate locations based on their dimensions, reducing the operational burden on operators while maintaining precise control over multiple workpieces

Inventive Principle:
Principle #25Self-service
