Solution Overview

Problem

Current methods for positioning elements on a sacrificial panel during machining, such as suction cups or panels to be machined, are prone to incorrect placement, require significant operator experience, lead to long machine downtimes, and are imprecise, especially for irregularly shaped panels, resulting in increased costs and production delays.

Innovation Solution

A method involving reading positioning data, marking graphic or engraving signs on the sacrificial panel to guide the placement of elements, and using suction cups with a vacuum system to secure them, allowing for precise and quick positioning independent of operator experience, and enabling efficient reuse of the panel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual positioning is used, then operator flexibility is maintained, but positioning precision deteriorates and machine downtime increases

Engineering Contradiction:
Improveoperator flexibilityVSAvoidpositioning precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent introduces positioning signs as an intermediary element between the operator and the element to be positioned. These signs provide visual guidance and reference points on the sacrificial panel, enabling operators to accurately place elements without requiring extensive experience or complex automated systems. The positioning signs act as a mediator that translates complex positioning requirements into simple visual cues.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Speed

If semi-automatic positioning with laser pointer is used, then positioning speed is improved, but positioning reliability deteriorates due to element movement

Engineering Contradiction:
Improvepositioning speedVSAvoidpositioning reliability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-marking positioning signs on the sacrificial panel before element placement. These signs remain fixed on the panel surface, providing stable reference points that do not move during the positioning process. This eliminates the reliability issue of laser pointers by establishing permanent visual markers that guide element placement throughout the operation.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If no positioning reference is provided, then device complexity is reduced, but positioning precision deteriorates significantly

Engineering Contradiction:
Improvepositioning system complexityVSAvoidelement placement precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent extracts the positioning reference function from complex automated positioning systems and implements it through simple visual markers directly on the sacrificial panel. By separating the reference marking function from the positioning execution, the system achieves high precision without requiring complex positioning mechanisms, controllers, or sensors.

Inventive Principle:
Principle #2Taking out (Extraction)

4Manufacturing precision

If multiple positioning adjustments are made, then positioning precision is improved, but machine downtime increases

Engineering Contradiction:
Improvepositioning precisionVSAvoidmachine downtime
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The positioning signs are prepared in advance on the sacrificial panel, allowing operators to directly place elements in the correct position without iterative adjustments. This preliminary preparation of reference markers eliminates the need for multiple positioning attempts and reduces machine downtime while maintaining high positioning precision.

Inventive Principle:
Principle #10Preliminary action
