Solution Overview

Problem

Existing vulcanization devices suffer from uneven tire vulcanization due to large temperature differences within the vulcanizing bladder, leading to degraded quality and difficulty in maintaining the heating device components.

Innovation Solution

A vulcanization device with an electromagnetic induction system to rotate the air outlet member, driven by a permanent magnet and armature winding, which circulates high-temperature gas medium for uniform temperature distribution, and a compact heating assembly design with a deflector shield to enhance heat exchange efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If an internal heating device is used to heat the gas medium in the vulcanizing bladder, then the vulcanization process can be performed, but the temperature distribution becomes uneven and the device is difficult to maintain

Engineering Contradiction:
Improvetemperature uniformityVSAvoidmaintenance difficulty
Core Design Contradiction:
TemperatureVSEase of repair

Solution Approach 1:

The heating device is extracted from the internal structure and relocated to the external environment. The heating assembly is now positioned outside the vulcanizing bladder, with heating elements that extend through the mold to heat the gas medium from the exterior, making the device easier to maintain and repair while improving temperature uniformity

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The gas medium itself serves as an intermediary carrier of heat. Instead of direct contact heating from internal elements, the heating assembly heats the gas medium which then circulates and distributes heat uniformly throughout the vulcanizing bladder, solving both the temperature uniformity and maintenance difficulty issues

Inventive Principle:
Principle #24Intermediary (Mediator)

2Temperature

If the gas medium is heated by an internal heating assembly, then vulcanization can proceed, but the gas medium circulation flow is poor and temperature differences are large

Engineering Contradiction:
Improvetemperature uniformityVSAvoidvulcanization efficiency
Core Design Contradiction:
TemperatureVSProductivity

Solution Approach 1:

The heating system is made dynamic by enabling movement of the heating assembly relative to the mold and vulcanizing bladder. The heating assembly can be adjusted to different positions and angles, allowing optimal heat distribution patterns that enhance gas medium circulation and temperature uniformity while maintaining high vulcanization efficiency

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The heating approach transitions from a single-point internal heat source to a multi-dimensional external heating system. The heating assembly incorporates heating elements that radiate heat in multiple directions and dimensions, creating more uniform temperature distribution and improving gas medium circulation throughout the vulcanizing chamber

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
