Solution Overview

Problem

Current methods cannot automate the production of an endless strip from multiple metal sheets, requiring manual manufacturing steps due to the inability to bend and weld multiple sheets simultaneously.

Innovation Solution

A method involving a removable connecting element to form a composite panel from multiple metal sheets, which can then be processed automatically, using tension belts to shape and weld the sheets into an endless strip.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple metal sheets are processed manually to form an endless strip, then manufacturing flexibility is maintained, but productivity is low and automation is not achieved

Engineering Contradiction:
Improveproduction efficiencyVSAvoidautomation capability
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The metal sheets are divided into individual units that can be independently handled and connected. Each sheet is processed separately through the forming device, and connecting elements are used to join them into an endless strip, enabling automated high-speed production while maintaining flexibility in sheet selection and arrangement.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Connecting elements serve as intermediaries between individual metal sheets. These elements facilitate the automated connection process by providing standardized interfaces that can be quickly joined and disconnected, enabling the transition from manual to automated manufacturing while maintaining production flexibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Extent of automation

If metal sheets are welded together to achieve desired strip length, then the endless strip can be formed, but the process requires manual operations and cannot be fully automated

Engineering Contradiction:
Improveautomation capabilityVSAvoidprocess complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The system is designed to automatically perform forming, positioning, and connecting operations without manual intervention. The connecting elements are automatically positioned and joined to metal sheets through the forming device, enabling the process to serve itself and achieve full automation while managing complexity through standardized procedures.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention changes the connection method from permanent welding to removable connecting elements that can be automatically attached and detached. This parameter change in the joining mechanism enables automated operation while reducing process complexity through reversible, standardized connections that are easier to control mechanically than welding processes.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If a single metal sheet is processed, then the existing method works, but it cannot produce endless strips from multiple sheets

Engineering Contradiction:
Improvecapability to process multiple sheetsVSAvoidmanufacturing simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The forming device is designed with universal capabilities to process multiple metal sheets through the same automated sequence. The device can handle different sheet configurations and lengths by using interchangeable connecting elements, maintaining manufacturing simplicity while achieving versatility in producing endless strips from multiple sheets.

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

Solution Approach 2:

Metal sheets are prepared in advance with connecting elements attached to their edges before entering the forming device. This preliminary action of pre-assembly simplifies the manufacturing process by reducing the complexity of in-line operations, while enabling the system to handle multiple sheets efficiently through standardized pre-prepared components.

Inventive Principle:
Principle #10Preliminary action
