Solution Overview

Problem

Existing cutting machines require operators to constantly switch attention between screens and the cutting machine, leading to complex and error-prone operations, increased waste, and safety risks due to distraction.

Innovation Solution

An improved method using augmented reality to superimpose cutting sequences and feedback on real-time images of the panel, allowing operators to maintain focus on the cutting process while receiving optical, acoustic, or haptic guidance for accurate positioning and waste management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If operators use traditional cutting machines with screens displaying cutting sequences, then operators can receive cutting instructions, but operators must constantly switch attention between screens and the cutting machine, leading to complex and error-prone operations

Engineering Contradiction:
Improvecutting sequence informationVSAvoidoperator attention management
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent introduces an augmented reality display as an intermediary device that bridges the gap between the cutting machine interface and the physical cutting area. The display superimposes cutting sequence information directly onto the operator's field of view, allowing simultaneous access to instructions and the cutting area without requiring attention switching. This mediator resolves the contradiction by making information accessible in the original context of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transitions cutting sequence information from a two-dimensional screen display to a three-dimensional augmented reality overlay that exists in the operator's physical workspace. By projecting virtual cutting lines, panel positions, and sequence steps into the physical space above the cutting area, the system allows operators to perceive cutting information in the same spatial dimension as the actual cutting operation, eliminating the need to shift attention between separate viewing planes.

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

2Loss of information

If operators constantly switch attention between screens and cutting machine, then operators can access cutting instructions, but this leads to increased errors and waste

Engineering Contradiction:
Improvecutting sequence informationVSAvoidcutting accuracy
Core Design Contradiction:
Loss of informationVSManufacturing precision

Solution Approach 1:

The augmented reality display acts as an intermediary that delivers cutting sequence information directly to the operator's visual field without requiring distraction from the cutting area. This maintains continuous visual contact with the panel and cutting tool while providing real-time guidance on cut lines, panel positioning, and sequence steps, thereby preventing positioning errors and improving cutting precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system provides real-time feedback by displaying cutting sequence information, panel position indicators, and instructional cues directly in the operator's field of view. This immediate feedback loop allows operators to verify their actions against the required cutting sequence without looking away, reducing errors and improving manufacturing precision through continuous visual confirmation.

Inventive Principle:
Principle #23Feedback

3Loss of information

If operators constantly switch attention between screens and cutting machine, then operators can receive instructions, but this creates safety risks due to distraction

Engineering Contradiction:
Improvecutting sequence informationVSAvoidoperator safety
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The augmented reality display serves as a safe intermediary that delivers cutting instructions without requiring operators to look away from the cutting area. By projecting information directly into the operator's field of view above the panel, the system eliminates the safety hazard of distraction while maintaining continuous visual awareness of the cutting zone, tool position, and panel location.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Productivity

If traditional cutting machines are used without augmented reality, then device complexity is lower, but the cutting process is slower and less efficient

Engineering Contradiction:
Improvecutting process speedVSAvoidcutting system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The augmented reality display is introduced as an intermediary information delivery system that enhances productivity without fundamentally redesigning the cutting machine mechanics. By overlaying cutting sequences, panel positions, and instructional information in the operator's field of view, the system accelerates the cutting process through improved information access while maintaining the existing cutting mechanism, thus managing complexity incrementally.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The augmented reality display system serves multiple functions simultaneously: displaying cutting sequences, indicating panel positions, providing instructional guidance, and showing real-time feedback. This multi-functionality consolidates multiple information delivery roles into a single device, improving productivity without proportionally increasing overall system complexity.

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