Solution Overview

Problem

Existing laser machining technologies face challenges in achieving high-precision positioning of the laser head, as users often rely on visual recognition, which is inadequate for precise operations.

Innovation Solution

A method and system for positioning a movable head, which includes displaying a marking point on a target interface to represent the coordinate position of the movable head, and adjusting this marking point in real-time as the movable head is displaced, ensuring accurate alignment with machining elements input on the interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If visual recognition with naked eye is used to recognize laser head position, then the operation is simple, but the positioning precision is insufficient

Engineering Contradiction:

Improveoperation simplicityVSAvoidpositioning precision

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

A marking point is introduced as an intermediary visual element that maps the laser head position to the target interface. This marking point serves as a mediator between the physical laser head and the digital interface, allowing users to accurately perceive the laser head position without directly observing the laser head itself, thus resolving the contradiction between simple operation and precise positioning.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The laser head position is copied and represented as a marking point on the target interface. This virtual copy allows users to interact with and observe the position information in a simplified 2D interface while maintaining accurate correspondence with the physical 3D space, achieving both operational simplicity and positioning precision.

Inventive Principle:

Principle #26Copying

2Measurement precision

If real-time position mapping is implemented, then positioning accuracy is improved, but system complexity increases

Engineering Contradiction:

Improvepositioning accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system implements real-time feedback by continuously updating the marking point position on the target interface as the laser head moves. This feedback mechanism provides users with immediate visual information about the laser head position, enabling precise positioning control without requiring complex manual measurement or calculation systems.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces complex mechanical positioning measurement systems with a software-based virtual mapping system. The marking point on the target interface is generated and updated through software calculations rather than physical measurement devices, reducing mechanical complexity while maintaining positioning accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A method for positioning a movable head is provided, the method includes: displaying a marking point on a target interface in response to a request for obtaining position information of the movable head; the marking point characterizes a coordinate position of the movable head mapped to the target interface; and making the marking point displace on the target interface correspondingly when the movable head is displaced, to make the marking point fall on a machining element input on the target interface.
