Solution Overview

Problem

The separate production and processing of preforms into containers, along with the associated storage and transportation, lead to inefficiencies, damage, and contamination, resulting in increased costs and reduced quality.

Innovation Solution

An integrated container treatment system that synchronizes the operations of an injection molding machine for producing preforms and a blow molding machine for forming containers, eliminating the need for intermediate storage and transportation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If preforms are produced and processed separately in time and location with intermediate storage and transportation, then production flexibility is improved, but preform damage and contamination occur

Engineering Contradiction:

Improveproduction flexibilityVSAvoidpreform quality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines the preform production machine and container treatment machine into a single integrated system where preforms are produced and immediately processed without intermediate storage or transportation. This merging eliminates the quality deterioration caused by separate production and processing while maintaining production flexibility through coordinated operation of both functions within the same system.

Inventive Principle:

Principle #5Merging (Combining)

2Productivity

If preforms are stored as bulk material in a storage unit, then production continuity is improved, but storage and transportation costs increase

Engineering Contradiction:

Improveproduction continuityVSAvoidstorage and transportation costs

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The integrated system enables continuous production and processing of preforms without interruption for storage or transportation. The preform production machine and container treatment machine operate in a continuous flow, eliminating idle storage periods and associated costs while maintaining production continuity through direct transfer between processing stages.

Inventive Principle:

Principle #20Continuity of useful action

3Ease of manufacture

If preforms are transported to the container treatment machine, then production separation is improved, but contamination risk increases

Engineering Contradiction:

Improveproduction separationVSAvoidcontamination

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

By integrating the preform production machine and container treatment machine into one system, the patent eliminates the need for transporting preforms between separate facilities. This merging removes the contamination risk associated with transportation while maintaining the functional separation of production and treatment operations within the same protected environment.

Inventive Principle:

Principle #5Merging (Combining)
