Tire Vulcanization Sensor Wiring via Segmented Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire vulcanization devices face challenges in accurately determining the state of a tire during the vulcanization process due to indirect detection methods for temperature and pressure, and they require complex wiring operations when replacing molds.
Innovation Solution
A tire vulcanization device with sensors installed on the mold and connectors that allow for easy connection and disconnection of lead wires, enabling direct data acquisition from sensors embedded on the tire molding surface, and simplifying the wiring process by allowing lead wires to move with the mold components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a temperature sensor is embedded in the vulcanization mold to directly detect tire temperature, then measurement precision is improved, but device complexity increases due to complicated wiring operations
Solution Approach 1:
The lead wire system is segmented into two separate connectors: a mold-side connector attached to the vulcanization mold and an in-container connector attached to the vulcanization container. This segmentation allows the lead wire to be disconnected when the mold is removed, eliminating the need for complex rewiring operations while maintaining direct temperature detection capability.
Solution Approach 2:
The connector system is designed to be dynamically connectable and disconnectable. The mold-side connector and in-container connector can be freely connected when the mold is installed and disconnected when the mold is removed, allowing the wiring system to adapt to the changing operational state without requiring complex permanent wiring.
2Measurement precision
If lead wires are wired to the vulcanization mold to connect temperature sensors, then measurement precision is improved, but ease of operation deteriorates due to complicated wiring work required during mold replacement
Solution Approach 1:
The lead wire connection is divided into two independent connector components that can be separately attached and detached. This segmentation transforms the complex task of rewiring the entire lead wire system into a simple connector attachment/detachment operation, dramatically improving ease of operation during mold replacement.
Solution Approach 2:
The mold-side connector is pre-installed on the vulcanization mold and the in-container connector is pre-installed on the vulcanization container before the actual sensing operation. This preliminary preparation eliminates the need for complex wiring work during mold replacement, as operators only need to simply connect the two pre-prepared connectors.
3Device complexity
If indirect detection methods are used for temperature and pressure, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
A lead wire acts as an intermediary element, transmitting electrical signals from the temperature sensor embedded in the vulcanization mold directly to the detection system outside the container. This intermediary connection enables direct tire temperature measurement while keeping the complex sensing components isolated within the mold, effectively resolving the contradiction between measurement precision and device complexity.

AI summary
In a mold of a tire vulcanization device, a sensor is installed in a state exposed on a tire molding surface, a connector is installed in a state exposed on an attachment surface, the sensor and the connector are connected by a lead wire extending through an interior of the mold. In container components, an inner connector is installed in a state exposed on an opposing surface, and a lead wire connected to the inner connector is extended through an interior of the container components toward an exterior of the container components.
