Solution Overview

Problem

Existing mobile vulcanizing presses face challenges with compactness and ease of handling due to protruding tie bolts, limited pivoting range adjustments, and increased setup times, making them less suitable for mobile applications with limited installation space.

Innovation Solution

A mobile vulcanizing press design featuring pivotable tie bolts with elastic latching means that can be easily adjusted and secured without additional tools, allowing for compact configuration and efficient handling, with features like flush box arrangements and integrated heating plates to optimize space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If tie bolts are permanently attached to the bottom box, then the vulcanizing press maintains structural stability, but the installation space requirement increases and mobility decreases

Engineering Contradiction:
Improveinstallation spaceVSAvoidstructural stability
Core Design Contradiction:
Volume of moving objectVSStability of the object's composition

Solution Approach 1:

The tie bolt system is segmented into removable and fixed parts. The tie bolts can be completely detached from the bottom box when not needed, separating the securing function from the base structure. This allows the press to have a compact configuration during transport while maintaining full securing capability during operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tie bolt arrangement transitions from a static permanent attachment to a dynamic removable configuration. The tie bolts can be quickly attached and detached without tools, allowing the system to adapt between mobile (bolts removed) and stable (bolts attached) states based on operational needs.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If locking pins and cotter pins are used to secure pivoting range, then the tie bolts maintain fixed positioning, but the adjustment time increases and tool requirements increase

Engineering Contradiction:
Improveadjustment easeVSAvoidsetup time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The locking function is extracted from complex multi-component systems (locking pins, cotter pins) and integrated directly into the tie bolt design through self-latching mechanisms. This eliminates the need for separate locking components and their associated assembly steps, allowing quick adjustment without tools.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The tie bolts incorporate self-latching and self-locking features that automatically secure themselves in the desired pivoting position without requiring external locking components or tools. The user simply positions the bolt, and the self-latching mechanism maintains the position, enabling tool-free adjustment.

Inventive Principle:
Principle #25Self-service

3Length of stationary object

If nuts and tie bolts protrude beyond the cope surface, then the securing mechanism provides adequate clamping force, but the overall dimensions of the vulcanizing press increase

Engineering Contradiction:
Improvepress dimensionsVSAvoidclamping force
Core Design Contradiction:
Length of stationary objectVSStrength

Solution Approach 1:

The tie bolt and nut assembly is nested within recesses in the cope and bottom box surfaces. When secured, the components sit flush with or recessed into the surfaces, similar to nested dolls where one object fits within another. This maintains adequate clamping force through the securing mechanism while eliminating protrusions that would increase overall press dimensions.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

The invention relates in particular to a mobile vulcanizing press (20) comprising a bottom box (22) and a top box (21), which can be arranged one above the other with material V to be vulcanized in between. The bottom box (22) and/or the top box (21) has/have at least one first bolt receiving section (32a), in which a tension bolt (11) can be pivotally located and at least one detent point (35a) is located on the bottom box (22) or the top box (21), such that a detent means (14) of the tension bolt (11) can engage in the at least one detent point (35a) in at least one predetermined pivoting position of the tension bolt (11).
