Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing preform supply devices for blow-molding of thermoplastic containers face inefficiencies due to time-consuming adjustments required for accommodating different preform formats, leading to potential stoppages and difficulties in repeatable adjustments.

Innovation Solution

A file-forming slide device with adjustable guiding elements mounted on support plates, utilizing quick-release fasteners and ball locking mechanisms, allows for rapid detachment and reattachment of guiding elements to adapt to various preform formats without requiring extensive re-adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If guiding elements are made adjustable to accommodate different preform formats, then adaptability is improved, but device complexity and adjustment time increase

Engineering Contradiction:

Improveadaptability to different preform formatsVSAvoidcomplexity of adjustable guiding elements

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The guiding elements are divided into modular components that can be independently adjusted and positioned. Each guiding element can be segmented into adjustable parts that work together to accommodate different preform formats without requiring complete reconfiguration of the entire system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The guiding elements incorporate dynamic adjustment mechanisms that allow for quick repositioning between different formats. The adjustable components enable the system to adapt its configuration dynamically rather than requiring static reconfiguration for each format change.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If guiding elements are made adjustable for different preform formats, then versatility is improved, but adjustment time and productivity are reduced

Engineering Contradiction:

Improveadaptability to different preform formatsVSAvoidproduction efficiency during format changes

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The guiding elements are designed with pre-configured adjustment positions and standardized mounting features that allow for rapid repositioning. Adjustment mechanisms are prepared in advance with clear positioning references, enabling operators to quickly switch between formats without extensive measurement and alignment work.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Traditional manual adjustment mechanisms are replaced with faster-acting systems such as quick-release clamps, cam locks, or tool-free adjustment devices. These mechanical substitutions reduce the time and effort required to reposition guiding elements compared to conventional bolt-and-nut adjustment systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If multiple adjustment operations are required for format changes, then adaptability is improved, but adjustment difficulty and downtime increase

Engineering Contradiction:

Improveadaptability to different preform formatsVSAvoidease of adjustment operations

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Multiple adjustment operations are merged into integrated adjustment mechanisms. The guiding elements are designed so that adjusting one parameter automatically adjusts related parameters, or multiple adjustments can be performed simultaneously through a single operation, reducing the number of discrete steps required.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The guiding elements incorporate universal adjustment features that can accommodate multiple preform formats using the same adjustment mechanism. A single adjustment system performs multiple functions, allowing operators to switch between different formats using the same procedure and components rather than requiring format-specific adjustment operations.

Inventive Principle:

Principle #6Universality (Multi-functionality)
