Solution Overview

Problem

Modern tire-producing plants face the challenge of increasing flexibility to quickly change the type of tire produced from one batch to another without idle time, particularly in managing different sizes and types of annular anchoring structures.

Innovation Solution

A method and plant design that involves two storage and transport lines for annular anchoring structures, allowing for the simultaneous management of different sizes and types of bead cores and filling inserts, enabling seamless transition between tire batches by preparing and feeding the correct anchoring structures to the bead-forming machine during production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single storage and transport system is used for annular anchoring structures, then the device complexity is low, but the adaptability to produce different tire batches is reduced

Engineering Contradiction:

Improveability to change tire type between batchesVSAvoidnumber of storage and transport lines

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The storage and transport system is divided into two separate lines: a first storage region with a first transport line and a second storage region with a second transport line. Each line is dedicated to storing and transporting specific types or sizes of annular anchoring structures, allowing independent management and quick switching between different tire batch requirements without interfering with each other.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bead-forming machine acts as an intermediary that receives annular anchoring structures from either the first or second storage region through their respective transport lines. This intermediary position allows the system to flexibly select and feed the appropriate anchoring structures for different tire batches, enhancing adaptability while maintaining organized storage and transport operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If production switches between different tire batches, then market responsiveness improves, but idle time increases without proper preparation

Engineering Contradiction:

Improvecontinuous production capacityVSAvoididle time between batches

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The second storage region is prepared in advance with annular anchoring structures for the next tire batch while the first batch is being produced. The second transport line is ready to immediately supply these pre-prepared anchoring structures to the bead-forming machine when the current batch completes, eliminating idle time and ensuring continuous productivity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The dual storage and transport system enables continuous useful action by ensuring that while one batch is being produced, the next batch's components are being prepared and positioned. The bead-forming machine can continuously operate without interruption as annular anchoring structures are always available from the appropriate storage region, maintaining constant production capacity.

Inventive Principle:

Principle #20Continuity of useful action

3Ease of operation

If multiple types of annular anchoring structures are managed in one system, then the quantity of components is consolidated, but the ease of operation decreases

Engineering Contradiction:

Improveease of switching between anchoring structure typesVSAvoidtotal number of anchoring structures to manage

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The system segments the management of annular anchoring structures by type or size across two separate storage regions. Each region stores specific varieties, allowing operators to easily access and switch between different types by simply selecting from the appropriate storage region without dealing with the complexity of managing all types in a single location.

Inventive Principle:

Principle #1Segmentation
