Solution Overview

Problem

Existing mold release lubricant application equipment for glass bottle forming molds only addresses the blank mold, neglecting the need for lubrication on both blank and blow molds, which is crucial for smooth glass bottle formation and releasability.

Innovation Solution

A comprehensive mold release lubricant application equipment that includes separate application portions and control mechanisms for both blank and blow molds, with transport mechanisms and sensors to ensure uniform lubrication and detect abnormalities, ensuring effective lubrication on both mold types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mold release lubricant is applied only to blank mold, then blank mold lubrication is achieved, but blow mold lubrication is neglected causing poor releasability

Engineering Contradiction:

ImprovereleasabilityVSAvoidcoverage of mold types

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The lubricant application equipment is designed to serve multiple mold types (blank mold and blow mold) through a unified system. The transport mechanism moves the lubricant application device between different mold sections, enabling the same equipment to perform lubrication functions on both blank molds and blow molds, thus achieving versatility and improving releasability across all mold types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If separate application portions are added for both blank and blow molds, then comprehensive lubrication is achieved, but device complexity increases

Engineering Contradiction:

Improvelubrication coverageVSAvoidnumber of application portions

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Instead of implementing completely separate lubrication systems for blank molds and blow molds, the patent merges both functions into a single integrated equipment. The transport mechanism combines the movement functions for both mold types, and the control portion统一管理 the lubrication process for both blank and blow molds, reducing overall system complexity while maintaining comprehensive lubrication coverage.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The lubricant application device is designed as a multi-functional unit that can service both blank molds and blow molds. By making the application portion universal rather than specialized for each mold type, the patent reduces the total number of components needed while ensuring both mold types receive proper lubrication.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Manufacturing precision

If transport mechanism moves lubricant application part among multiple sections, then uniform lubrication is achieved, but operation time increases

Engineering Contradiction:

Improveuniformity of lubricationVSAvoidapplication cycle time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The transport mechanism is designed to move the lubricant application device continuously or periodically between different mold sections without idle interruptions. The control portion coordinates the movement and application timing to ensure continuous lubrication coverage across all sections, maintaining uniformity while minimizing non-productive time through optimized motion sequences.

Inventive Principle:

Principle #20Continuity of useful action
