Solution Overview

Problem

Existing shoe manufacturing assembly lines lack flexibility, as they are not adaptable to produce various shoe types or structures efficiently, leading to increased production time and costs due to rigid setups and high labor and maintenance requirements.

Innovation Solution

A modular installation with multiple islands, each equipped with specific machines for preparation, machining, and finishing, along with a mobile frame and actuation device, allowing for flexible operation and reduced handling, enabling the production of different shoe types with real-time monitoring and synchronization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional assembly line is used for shoe manufacturing, then production speed can be maintained, but flexibility to produce different shoe types is lost

Engineering Contradiction:
Improveflexibility to produce different shoe typesVSAvoidproduction speed
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The assembly line is divided into multiple independent workstations (islands), each capable of performing specific operations. This segmentation allows different shoe types to be produced simultaneously at different stations, providing flexibility while maintaining overall production throughput through parallel processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each workstation is designed with universal capabilities to handle multiple shoe types and operations. The workstations can be reconfigured or reassigned to produce different shoe models, allowing the same production line to accommodate various product lines without complete retooling.

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

2Ease of manufacture

If highly automated manufacturing equipment is used, then labor costs are reduced, but maintenance costs and complexity increase

Engineering Contradiction:
Improvelabor cost reductionVSAvoidmaintenance requirements
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The system incorporates self-monitoring and self-adjustment capabilities at each workstation, allowing the equipment to detect and correct minor issues without external intervention. This reduces the need for complex maintenance systems while maintaining operational efficiency and reducing labor requirements.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manufacturing system uses adjustable parameters and settings that can be modified through simple interfaces rather than requiring complex mechanical reconfiguration. This allows easy adaptation to different shoe types while maintaining manageable system complexity and reduced maintenance needs.

Inventive Principle:
Principle #35Parameter changes
