Solution Overview

Problem

Existing cutting systems for flat materials face challenges in providing intuitive and accessible information for user guidance, material placement, and efficient sorting of cut pieces, particularly in harsh environments, due to complex and error-prone visualization tools and cost-intensive projectors.

Innovation Solution

A system that incorporates an augmented reality display device, such as AR glasses or a head-up display, to provide real-time information about the material's position, alignment, and quality zones, allowing for precise placement and sorting of cut pieces, using a camera for image processing and sensors for accurate positioning, and enabling gesture control for user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If complex projectors and visualization tools are used to provide material information and guidance, then information completeness is improved, but device complexity and cost increase

Engineering Contradiction:
Improveinformation completenessVSAvoiddevice complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent uses a camera to capture images of the material and displays them on a screen, creating a visual copy of the material surface. This allows operators to view material information without complex projectors, reducing device complexity while maintaining information completeness. The camera-based approach replaces expensive projection systems with simpler imaging technology.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces mechanical projectors and physical visualization tools with electronic display systems. The camera captures material images, which are then processed and displayed on a screen, substituting mechanical projection mechanisms with electronic imaging and display technology, thereby reducing device complexity.

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

2Loss of information

If traditional projectors are used for material visualization, then information provision is improved, but reliability in harsh environments deteriorates

Engineering Contradiction:
Improveinformation provisionVSAvoidreliability
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

The camera creates a digital copy of the material surface that can be displayed and analyzed without exposing sensitive projection equipment to harsh environmental conditions. The imaging system remains protected while still providing complete material information through the captured images.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The camera and display system act as an intermediary between the material and the operator. Instead of projectors directly interacting with the material in harsh environments, the camera captures images that are then displayed, creating a buffer that protects the visualization equipment while maintaining information provision.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If manual material placement and sorting is performed without guidance, then operation simplicity is improved, but productivity and accuracy deteriorate

Engineering Contradiction:
Improveoperation simplicityVSAvoidproductivity
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system provides visual feedback by displaying captured material images on a screen, showing operators the actual material surface, defects, and positioning information. This feedback loop enables operators to make informed decisions about material placement and sorting, improving both accuracy and productivity while maintaining operational simplicity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The camera captures and displays material images before the cutting or sorting process begins, allowing operators to pre-assess material quality, identify defects, and plan placement strategies. This preliminary visualization enables better preparation and decision-making, improving productivity without complicating the actual operation.

Inventive Principle:
Principle #10Preliminary action

4Measurement precision

If expensive projectors are used for quality zone visualization, then measurement precision is improved, but loss of substance increases due to material waste

Engineering Contradiction:
Improvequality zone detection precisionVSAvoidmaterial waste
Core Design Contradiction:
Measurement precisionVSLoss of substance

Solution Approach 1:

The camera creates accurate visual copies of quality zones and material defects, enabling precise identification and mapping of problematic areas. This allows operators to plan cutting paths that avoid defects and optimize material usage, improving measurement precision while reducing material waste through better nesting and placement strategies.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The displayed material images provide immediate visual feedback about quality zones and defects, enabling operators to adjust placement and cutting strategies in real-time. This feedback allows for optimization of material utilization by avoiding defective areas and improving nest efficiency, thereby reducing material waste while maintaining detection precision.

Inventive Principle:
Principle #23Feedback
