Solution Overview

Problem

Current machines for processing panels, such as wood, plastic, metal, and glass, face inefficiencies in detecting and repositioning cut panels after nesting-type processing, as each panel must be manually assigned a spatial reference by a pick-up device, leading to time-consuming and complex procedures.

Innovation Solution

A machine equipped with a processing unit, a detection unit, and a logic control unit that uses linear scanning and image reconstruction to determine the position of cut panels on a working plane, allowing for precise orientation and transport of panels to subsequent processing stations without the need for manual reference assignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a pick-up device manually assigns spatial reference to each cut panel, then the panels can be transported and processed in subsequent stations, but the procedure becomes time-consuming and complex

Engineering Contradiction:
Improvespatial reference assignmentVSAvoidprocessing speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the mechanical pick-up device that manually assigns spatial references with an optical detection system (camera) that automatically captures and processes images of cut panels. The detection unit captures images of all panels simultaneously, and the control unit automatically determines positions and orientations, eliminating the need for mechanical manipulation and manual reference assignment.

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

Solution Approach 2:

The patent creates an optical copy (image) of the panel arrangement on the working plane. Instead of physically manipulating each panel with a pick-up device, the system captures a visual representation of all panels simultaneously and processes this image data to determine positions and orientations, significantly reducing processing time.

Inventive Principle:
Principle #26Copying

2Measurement precision

If a pick-up device processes each panel individually to assign spatial reference, then accurate positioning is achieved, but the complexity of the procedure increases

Engineering Contradiction:
Improveposition detection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges the detection of multiple panels into a single simultaneous operation. Instead of processing each panel individually through separate pick-up operations, the detection unit captures images of all panels on the working plane at once, and the control unit processes all position and orientation data in a unified manner, reducing system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system creates a comprehensive optical copy of the entire panel arrangement and processes this single image to extract position and orientation information for all panels simultaneously, maintaining measurement precision while reducing operational complexity.

Inventive Principle:
Principle #26Copying

3Reliability

If manual reference assignment is performed for each panel, then subsequent processing stations can recognize panel positions, but the overall processing time increases

Engineering Contradiction:
Improvepanel recognitionVSAvoidreference assignment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the time-consuming mechanical pick-up and reference assignment process with an optical detection system that instantly captures panel positions. The camera-based detection unit and control unit automatically generate recognition data for all panels simultaneously, eliminating the sequential manual processing time.

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

Solution Approach 2:

The detection and recognition process operates continuously and simultaneously for all panels rather than sequentially. The system maintains continuous operation by capturing all panel positions in a single imaging operation and processing the data without interruption, maximizing productivity.

Inventive Principle:
Principle #20Continuity of useful action
