Solution Overview

Problem

Existing machines for working wood panels face issues with suction cups moving from their assigned positions, leading to potential damage and increased operational costs due to incorrect positioning and the need for manual interventions.

Innovation Solution

A machine with a blocking and releasing device featuring pins that orient and secure the device on a sacrificial panel, allowing for vacuum retention and easy coupling, which includes making corresponding openings on the panel for the pins to ensure stable positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If suction cups are positioned manually on the sacrificial panel, then the positioning process is simple, but the suction cups can move from their assigned positions during operation

Engineering Contradiction:
Improvemanual positioning simplicityVSAvoidposition stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The blocking and releasing device is divided into separate components: a main body and pins that can be inserted into holes in the sacrificial panel. This segmentation allows the device to be easily positioned while the pins provide secure anchoring to prevent movement during operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Holes are pre-drilled in the sacrificial panel at the desired positions before the blocking and releasing devices are installed. This preliminary action enables quick and accurate positioning of the devices without requiring complex alignment procedures during installation.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If suction cups are secured to the sacrificial panel, then positioning stability is improved, but the time required for installation and removal increases

Engineering Contradiction:
Improveposition stabilityVSAvoidinstallation and removal time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The blocking and releasing device incorporates pins that can be easily inserted into and removed from holes in the sacrificial panel. This dynamic design allows for quick installation and removal while maintaining secure positioning during operation, reducing downtime between work cycles.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the blocking and releasing device is permanently fixed to the sacrificial panel, then position stability is maximized, but the adaptability to reposition or remove the device is reduced

Engineering Contradiction:
Improveposition stabilityVSAvoidrepositioning capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The pins act as intermediaries between the blocking and releasing device and the sacrificial panel. They provide secure mechanical connection when inserted into the pre-drilled holes, ensuring position stability during operation, while allowing the device to be easily removed and repositioned by simply extracting the pins, thus maintaining adaptability.

Inventive Principle:
Principle #24Intermediary (Mediator)
