Solution Overview

Problem

Existing horizontal machining centers face challenges in removing a single pallet without disrupting the vacuum supply, leading to inefficiencies during pallet change cycles.

Innovation Solution

The integration of an energy supply interface on the pallet carrier, which provides vacuum and other working media independently of the machining center, allowing for seamless pallet removal and introduction while maintaining vacuum supply during pivoting and turning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If a single pallet is removed from the horizontal machining center, then the pallet change cycle time is reduced, but the vacuum supply to the pallet is interrupted causing workpiece securing issues

Engineering Contradiction:
Improvepallet change cycle timeVSAvoidvacuum supply continuity
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

A portable power supply interface is introduced as an intermediary device that temporarily provides vacuum and other working media to the pallet during the transition phase when it is removed from the machining center. This interface travels with the pallet on the pivot arm, ensuring continuous vacuum supply throughout the pallet change operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The power supply connection transitions from a static connection to the machining center to a dynamic connection that moves with the pallet. The portable power supply interface is positioned on the pivot arm and moves synchronously with the pallet during pivoting and turning operations, maintaining continuous supply despite positional changes.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the power supply interface is attached to the pallet carrier, then continuous vacuum supply is maintained during pallet operations, but the device complexity increases

Engineering Contradiction:
Improvevacuum supply continuityVSAvoidpallet carrier system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The portable power supply interface is designed to provide multiple functions through a single integrated unit: vacuum supply, pneumatic supply, hydraulic supply, and electrical signal transmission. This multi-functional approach consolidates what would otherwise require separate systems for each working medium.

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

Solution Approach 2:

The power supply interface utilizes flexible connections including hoses and cables that can bend and extend as the pallet moves through its range of motion. These flexible elements allow the interface to maintain connections during dynamic operations without requiring rigid mechanical linkages.

Inventive Principle:
Principle #30Flexible shells and thin films

3Adaptability or versatility

If flexible supply lines are used to connect the interface to the stationary power supply, then the interface can move with the pallet carrier, but the risk of line collision and damage increases

Engineering Contradiction:
Improveinterface mobilityVSAvoidline collision risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The supply lines are routed through the third dimension by positioning them within the structural framework of the pivot arm. The hoses and cables are channeled through designated pathways and protective conduits that elevate them above the pallet's path of motion, preventing collision while allowing the interface to move freely with the pallet.

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

Solution Approach 2:

The flexible supply lines are nested within protective conduits and structural elements of the pivot arm assembly. The hoses are routed through hollow sections of the arm structure, and cables are contained within protective channels, providing mechanical protection while maintaining flexibility and movement capability.

Inventive Principle:
Principle #7Nested doll (Nesting)
