Solution Overview

Problem

Existing apparatus for post-treating tires after vulcanization are costly to manufacture and require complex arrangements for supporting and sealing tires during cooling, with multiple movable parts increasing structural complexity and sealing requirements.

Innovation Solution

The apparatus features stationary and positionable receiving areas for tires, supported by hydraulic clamping wheel plates, allowing for efficient sealing and cooling with a simplified design that minimizes movable parts and uses a modified press discharger for loading and unloading from one side, with compressed gas supply through stationary support elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple movable receiving devices are arranged to be pivotable relative to an axis of rotation, then several post-treatment locations are made available and charging at the same location is made possible, but the device complexity and manufacturing cost increase

Engineering Contradiction:

Improvenumber of post-treatment locationsVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of making the receiving devices movable and pivotable, the invention inverts the approach by making the receiving areas stationary and using a positionable handling device to move the tires between them. This reduces mechanical complexity while maintaining the capability to service multiple tires simultaneously.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The invention divides the system into stationary receiving areas and a separate movable handling device. This segmentation allows the receiving areas to be simple, fixed structures while the handling device handles all the movement and positioning, thereby reducing overall device complexity.

Inventive Principle:

Principle #1Segmentation

2Productivity

If multiple movable receiving devices are used, then post-treatment of multiple tires is enabled, but the manufacturing cost increases

Engineering Contradiction:

Improvepost-treatment capacityVSAvoidmanufacturing cost

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The invention inverts the conventional approach by making receiving areas stationary rather than movable. This dramatically reduces manufacturing costs while maintaining the ability to process multiple tires through the use of a positionable handling device that moves tires between stationary receiving areas.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The positionable handling device serves multiple functions: it transports tires between receiving areas, positions tires for post-treatment, and can service multiple receiving areas sequentially. This multi-functionality maintains productivity while reducing the need for multiple specialized devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Force

If support elements are made positionable to adapt to tire geometry, then adequate clamping forces are available, but the number of movable structural elements increases

Engineering Contradiction:

Improveclamping forceVSAvoidnumber of movable parts

Core Design Contradiction:

ForceVSDevice complexity

Solution Approach 1:

Instead of making support elements positionable, the invention inverts the approach by making the receiving areas stationary and using a positionable handling device to bring tires to the correct position. This reduces the number of movable parts while maintaining adequate clamping forces through the stationary receiving area design.

Inventive Principle:

Principle #13The other way round (Inversion)
