Solution Overview

Problem

Industrial vehicle tire owners face the challenge of extending tire life due to high costs, making it impractical to invest in specialized tire repair machines that are typically cost-effective only for tire repair shops, as these machines need frequent replacement with different tire types.

Innovation Solution

A machine with adaptable moulds, hydraulic and pneumatic systems, and a touch-screen control panel for hot tire repair, featuring movable and pivoting moulds, hydraulic actuators, and electric/pneumatic power for efficient repair across various tire types, allowing for sporadic use and cost-effective maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a specialized tire repair machine is purchased, then tire repair capability is improved, but the cost of the machine and equipment increases

Engineering Contradiction:
Improvetire repair capabilityVSAvoidcost of machine and equipment
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The machine is designed with multiple interchangeable nozzles that can adapt to different tire types and profiles. The stationary support with dihedral angle and replaceable nozzles allows a single machine to perform repair operations on various tire configurations, making it universally applicable rather than requiring separate machines for each tire type.

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

Solution Approach 2:

The machine structure is divided into modular components: a stationary support, a mobile support, and interchangeable nozzles. This segmentation allows the expensive machine body to remain while only relatively inexpensive nozzles need to be replaced when changing tire types, reducing the overall cost burden.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a tire repair machine is purchased, then tire repair function is improved, but the machine would need to be substituted every time the owner changed the type of tyres

Engineering Contradiction:
Improvetire repair functionVSAvoidadaptability to different tire types
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The machine incorporates a set of nozzles with different profiles that can be interchanged on the stationary support. This allows the same machine to accommodate multiple tire types and profiles without requiring complete machine substitution, achieving multi-functionality in a single device.

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

Solution Approach 2:

The machine features a mobile support that can move horizontally to adjust the position of the tire, and interchangeable nozzles that can be rotated or replaced to match different tire profiles. These dynamic adjustments allow the machine to adapt to various tire types while maintaining repair functionality.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If sophisticated equipment with different moulds is used, then repair precision is improved, but the ease of operation decreases due to complexity

Engineering Contradiction:
Improverepair precisionVSAvoidease of use
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The complex molding system is segmented into a stationary support with fixed dihedral angle and interchangeable nozzles. This segmentation allows the precision-critical components (nozzles) to be replaced independently while the main structure remains simple and easy to operate.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mobile support provides dynamic horizontal movement to position tires accurately, while the interchangeable nozzles can be quickly swapped to match different tire profiles. This dynamic capability achieves precision without requiring complex fixed infrastructure for each tire type.

Inventive Principle:
Principle #15Dynamics
