Solution Overview

Problem

Current filter devices for plasticized molding materials, particularly those using recycled plastics, face challenges with high contamination levels, leading to lengthy downtimes and reduced productivity due to the need for manual intervention and high acquisition costs of complex filtration systems, making the use of recycled materials less attractive and less energy-efficient.

Innovation Solution

A filter device with a movable housing system that allows for automatic and quick release of the filter element for cleaning or replacement, reducing downtimes and increasing energy efficiency by enabling continuous filtration without manual handling, and incorporating a temperature control system to solidify impurities with the filter element for easy removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a filter device with manual filter element replacement is used, then the filtration function is provided, but the downtime increases and productivity decreases due to manual intervention requirements

Engineering Contradiction:
ImproveproductivityVSAvoiddowntime
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The filter device enables automatic filter element replacement without manual intervention. The system includes automated mechanisms that allow the filter element to be replaced by the machine itself during operation, eliminating the need for operators to manually handle hot viscous molding material and reducing downtime associated with manual filter changes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The filter device is designed to maintain continuous filtration operation. The automated filter replacement system allows the filtration process to continue without interruption or minimal interruption, as the filter element can be replaced while the machine operates or with automatic restart capabilities, thereby maintaining continuous productive action.

Inventive Principle:
Principle #20Continuity of useful action

2Reliability

If complex filtration systems are used to handle high contamination levels, then the filtration effectiveness is improved, but the acquisition costs increase

Engineering Contradiction:
Improvefiltration effectivenessVSAvoidacquisition costs
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The filter device is divided into modular components including the filter housing, filter element, and automated replacement mechanism. This segmentation allows for a cost-effective design where each component can be independently manufactured and replaced, reducing the overall acquisition cost compared to complex integrated systems while maintaining filtration effectiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system handles high contamination levels through parameter changes in the filtration process rather than through complex hardware. This includes adjusting filtration speed, pressure differentials, and using replaceable filter elements with optimized pore structures that can be quickly changed, achieving effective filtration without expensive complex systems.

Inventive Principle:
Principle #35Parameter changes

3Ease of repair

If filter cleaning is performed manually, then the filter element can be maintained, but the downtime increases significantly

Engineering Contradiction:
Improvefilter maintenanceVSAvoiddowntime
Core Design Contradiction:
Ease of repairVSLoss of time

Solution Approach 1:

The filter device enables automatic filter element replacement without manual intervention. The system includes automated mechanisms that allow the filter element to be replaced by the machine itself during operation, eliminating the need for operators to manually handle hot viscous molding material and reducing downtime associated with manual filter changes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system is designed with pre-positioned filter elements and automated replacement mechanisms that are prepared in advance. When filter cleaning or replacement is needed, the system can quickly switch to a pre-prepared filter element, minimizing the downtime required for maintenance operations.

Inventive Principle:
Principle #10Preliminary action

AI summary

A filter device for plasticized molding material includes a filter housing and a filter element arranged in the filter housing. The filter housing has at least two housing elements movable relative to each other. A drive is provided, via which the housing elements are movable between an open position and a closed position. The filter element is at least partially released in the open position of the housing elements and can preferably be taken out of the filter housing.
