Solution Overview

Problem

Conventional spring vents for tire vulcanizing molds are difficult to maintain due to damage of engagement parts during valve structure replacement, leading to increased maintenance costs and decreased work efficiency.

Innovation Solution

A spring vent design featuring a spherical stopper with an elastic hole and plane surfaces, allowing the stopper to be easily deformed and restored for replacement without damaging the sleeve, enabling easy coupling and decoupling of the rod from the sleeve.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the engagement parts are damaged using a tool to remove the stopper, then the stopper can be removed from the casing, but the casing and valve structure are damaged and cannot be restored

Engineering Contradiction:
Improvevalve structure replacementVSAvoiddamage to casing and valve structure
Core Design Contradiction:
Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The valve structure is segmented into separate components: the valve body and the stopper. The stopper can be independently removed from the casing by deforming it elastically, while the casing and valve body remain intact and undamaged. This allows the stopper to be replaced without damaging other components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The stopper's physical state is temporarily changed by applying elastic deformation to reduce its diameter, allowing it to pass through the outlet of the casing. After removal, the stopper returns to its original shape. This parameter change enables easy removal and replacement without damaging the casing.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the entire mini vent is replaced due to damage, then the valve structure can be restored, but maintenance costs increase and work efficiency decreases

Engineering Contradiction:
Improverestoration of original shapeVSAvoidwork efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The design allows only the stopper component to be replaced independently, while the casing and valve body remain in use. This segmentation enables partial replacement rather than complete replacement, significantly improving work efficiency and reducing maintenance costs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The stopper's elastic properties allow it to be temporarily deformed for removal and then restored to its original shape after replacement. This parameter change capability ensures the stopper can be easily replaced and restored without replacing the entire mini vent system.

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If the stopper is made with a diameter greater than the outlet, then the valve structure is prevented from separating, but the stopper cannot pass through the outlet for replacement

Engineering Contradiction:
Improveprevention of separationVSAvoidreplacement of stopper
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The stopper's diameter is dynamically changed by applying elastic deformation during removal. The stopper is temporarily compressed to a smaller diameter to pass through the outlet, then returns to its larger original diameter to prevent separation when installed. This parameter change enables both secure installation and easy replacement.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The stopper transitions between two states: a larger diameter state for preventing separation during normal operation, and a smaller deformed state for easy removal and replacement. This dynamic state change allows the stopper to fulfill both functional requirements.

Inventive Principle:
Principle #15Dynamics

AI summary

A spring vent for a tire vulcanizing mold comprises: a sleeve having a flow path vertically passing therethrough; a head opening/closing an inlet at an upper end of the flow path; a rod comprising a bar-type body formed below the head and disposed along the flow path and a stopper formed below the body to be hung to an outside of an outlet at a lower end of the flow path; and a spring inserted into the body. The stopper of the rod is formed to have a spherical shape. An elastic hole having an open bottom is formed in the stopper.
