Solution Overview

Problem

Existing systems fail to efficiently automate the handling and machining of tubular elements, particularly in the handling and machining of tubular elements, due to the lack of precise identification and orientation, and the presence of scraps hindering subsequent operations.

Innovation Solution

A system comprising optical sensors distributed on a scanning plane orthogonal to the feeding direction, scanning tubular elements to determine their shape, orientation, and presence of scraps, and comparing the data with stored models to automate handling and machining.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual inspection is used to check tubular elements for scraps and machining correctness, then product quality can be ensured, but production speed decreases and full automation cannot be achieved

Engineering Contradiction:
Improveproduct qualityVSAvoidproduction speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces manual inspection with an automated optical scanning system using sensors to detect scraps and verify machining correctness. The scanning device captures images of tubular elements and automatically analyzes them to identify defects, eliminating the need for manual visual inspection while maintaining quality assurance and enabling continuous production operation.

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

Solution Approach 2:

The patent introduces an image processing system as an intermediary between the manufacturing process and quality assessment. The system uses captured images as intermediate data to automatically detect scraps, verify machining accuracy, and control product quality without requiring direct manual intervention, thereby maintaining both high speed and reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the handling device is equipped with advanced sensing and orientation capabilities to handle section bars in any orientation, then handling accuracy improves, but device complexity increases

Engineering Contradiction:
Improvehandling accuracyVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements preliminary scanning and identification of tubular elements before handling operations. The optical sensors capture images and determine the exact shape, position, and orientation of each element in advance, allowing the handling device to prepare appropriate gripping and positioning actions beforehand. This preliminary information gathering simplifies the actual handling operation while maintaining high accuracy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent employs a feedback mechanism where the scanning system continuously provides information about the tubular element's position and orientation to the control system. The control system processes this feedback information and adjusts the handling device's actions accordingly, enabling accurate handling of elements in any orientation through adaptive control rather than complex mechanical design.

Inventive Principle:
Principle #23Feedback
