Solution Overview

Problem

Existing manufacturing systems face inefficiencies due to the coupling of production stations and work processes with conveyor devices, leading to waiting times and overcapacity, which hinder the flow and acceleration of workpieces within a manufacturing plant.

Innovation Solution

A manufacturing station with station-bound transport means for production load carriers, allowing decoupling from conveyor devices, enabling flexible and multifunctional production load carriers that can be reloaded, processed, and transported between workstations, with a sequential transport system adapted to work cycles, and a storage option for buffering and optimizing production flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If production stations are coupled with conveyor devices, then material transport is ensured, but waiting times occur and overcapacity is created

Engineering Contradiction:
Improveproduction flowVSAvoidwaiting time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system segments the production flow by introducing station-bound transport means that operate independently from the external conveyor system. Each production station has its own dedicated transport capacity, allowing workpieces to be processed without waiting for conveyor availability. This segmentation eliminates the coupling between stations and conveyor devices, resolving the waiting time issue while maintaining continuous production flow.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The station-bound transport means prepares and positions workpieces at each production station in advance, ensuring that material is ready before processing begins. This preliminary action eliminates waiting times by ensuring that workpieces are available exactly when needed at each station, without requiring synchronization with external conveyor schedules.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If production stations are coupled with conveyor devices, then material transport is ensured, but overcapacity is created

Engineering Contradiction:
Improveproduction flowVSAvoidmaterial usage
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

By segmenting the transport system into station-bound units, each station processes workpieces independently without requiring excess material buffering. The localized transport means delivers exactly the required material quantity to each station, eliminating overcapacity and unnecessary material usage while maintaining continuous production flow.

Inventive Principle:
Principle #1Segmentation

3Loss of time

If station-bound transport means are introduced, then waiting times are reduced, but device complexity increases

Engineering Contradiction:
Improvewaiting timeVSAvoidtransport system
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The station-bound transport means is designed as a universal, multi-functional unit that can serve multiple production stations. This modular design reduces overall system complexity by using standardized components across different stations, rather than requiring custom complex conveyor systems for each station. The universal transport unit handles both material delivery and positioning functions.

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

4Adaptability or versatility

If production load carriers are made flexible and multifunctional, then production flexibility is improved, but device complexity increases

Engineering Contradiction:
Improveproduction flexibilityVSAvoidload carrier
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The production load carrier is designed as a universal platform that can accommodate different workpiece types, sizes, and configurations. This multi-functional design allows the same load carrier to be used across multiple production stations and for different production runs, improving flexibility without requiring complex specialized carriers for each application. The standardized interface simplifies handling while maintaining adaptability.

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