Solution Overview

Problem

Operators of machine tools, such as circular saws, face challenges in efficiently managing settings and configurations due to the need to frequently switch between viewing a control screen and the machine, leading to increased errors, machining waste, and safety risks due to distraction.

Innovation Solution

Implementing a method that uses augmented reality to display information directly on the machine tool's environment, allowing operators to view configuration parameters and interact with virtual commands overlaid on real images, reducing the need for constant screen monitoring and enhancing ergonomic operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If information is displayed on a control screen, then information is provided to the operator, but the operator must frequently switch between the screen and the machine, increasing errors and safety risks

Engineering Contradiction:
Improveinformation accessVSAvoidoperational safety
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

The patent transitions the information display from a two-dimensional screen to a three-dimensional augmented reality overlay that appears to float in the operator's field of view. This dimensional change allows information to be viewed without shifting gaze to a separate screen, eliminating the need for frequent attention switching and reducing safety risks while maintaining complete information access.

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

Solution Approach 2:

The patent introduces an augmented reality display system as an intermediary between the control screen and the operator's direct view of the machine. This intermediary technology projects information into the operator's visual field, serving as a bridge that allows simultaneous viewing of both machine operations and configuration information without requiring the operator to physically move between viewing locations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If information is displayed on a control screen, then configuration parameters are visible, but the operator experiences distraction and increased error rates

Engineering Contradiction:
Improveconfiguration informationVSAvoidoperational focus
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

By projecting configuration information into the three-dimensional space above the machine rather than confining it to a two-dimensional screen, the system allows operators to view all necessary parameters while maintaining their focus on the machine operations. This spatial repositioning of information eliminates the cognitive load of switching attention between separate viewing locations.

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

3Device complexity

If a concentrated interface area is used, then the control system is compact, but the operator must move gaze continuously between screen and machine

Engineering Contradiction:
Improveinterface layoutVSAvoidgaze switching time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent eliminates the need for a physically concentrated interface area by projecting the interface into the operator's field of view in three-dimensional space. This allows the interface to be virtually positioned wherever needed in the operator's visual field, removing the time loss associated with physically moving gaze between a concentrated screen location and the machine.

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

4Loss of information

If traditional display methods are used, then information is provided, but non-expert operators struggle to manage settings efficiently

Engineering Contradiction:
Improvesettings informationVSAvoidoperator expertise requirement
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent applies local quality by positioning specific configuration information and controls in proximity to their corresponding physical machine components in the augmented reality display. This spatial correspondence allows operators to understand the relationship between controls and machine parts intuitively, reducing the expertise required to manage settings efficiently.

Inventive Principle:
Principle #3Local quality
