Solution Overview

Problem

Current workpiece transport devices require serial feeding and removal of workpieces, which can lead to inefficiencies in processing capacity and handling precision, especially as the processing capacity increases, necessitating improved methods for handling multiple workpieces in the correct order.

Innovation Solution

A workpiece transport device with multiple receiving and removal positions, equipped with signaling means such as optical and acoustic indicators, allows for the correct placement and removal of workpieces based on pre-programmed sequences, enabling simultaneous handling and processing of multiple workpieces in an optimized manner.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If workpieces are fed and removed serially one after another, then the device construction remains simple, but the processing capacity and operational efficiency are limited

Engineering Contradiction:
Improveprocessing capacityVSAvoiddevice construction complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The workpiece transport device is divided into multiple workpiece receiving positions (first, second, third receiving positions) arranged in parallel, allowing simultaneous placement of multiple workpieces. This segmentation enables parallel processing while maintaining a relatively simple overall device structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from a single-file serial arrangement to a multi-position parallel arrangement by adding spatial dimensions. Multiple receiving positions are distributed across different locations, allowing workpieces to be processed simultaneously in parallel streams rather than sequentially.

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

2Productivity

If multiple workpieces are processed in parallel, then processing capacity increases, but the complexity of ensuring correct order and positioning increases

Engineering Contradiction:
Improveprocessing capacityVSAvoidworkpiece positioning precision
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The invention incorporates signaling means that provide visual feedback to indicate which workpiece receiving position should be filled next and which position's workpiece should be removed first. This feedback mechanism ensures correct ordering and positioning without requiring complex manual tracking or control systems.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The signaling means utilize visual indicators (such as colored lights or visual displays) to communicate the status of different workpiece positions. These visual signals change or activate to guide operators on where to place and remove workpieces, ensuring precision in parallel operations.

Inventive Principle:
Principle #32Color changes

3Productivity

If workpiece receiving positions are arranged in parallel, then simultaneous handling of multiple workpieces is enabled, but the device footprint and space requirements increase

Engineering Contradiction:
Improveparallel handling capabilityVSAvoiddevice footprint
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The invention combines multiple workpiece receiving positions and conveyor paths into a single integrated transport device. By merging these functions into one coordinated system rather than separate devices, the footprint is minimized while still enabling parallel workpiece handling.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The workpiece receiving positions and conveyor mechanisms are arranged in a nested or compact configuration where components are space-efficiently organized. The parallel receiving positions are arranged to share common structural elements and control systems, reducing the overall device area.

Inventive Principle:
Principle #7Nested doll (Nesting)
