Solution Overview

Problem

Current disposable filtration devices are limited to smaller filter elements and lack integration into automated processes, necessitating a need for a ready-to-use, partially or fully automated filtration device suitable for large-scale operations, especially in commercial pharmaceutical production.

Innovation Solution

An automated disposable filtration device equipped with sensors and control devices connected to an external monitoring and control system, allowing for continuous process parameter monitoring and control, including flow, pressure, and venting, to facilitate partially or fully automated filtration processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If disposable filtration devices are used for large-volume filtration processes, then filtration capacity is improved, but automation capability deteriorates

Engineering Contradiction:
Improvefiltration capacityVSAvoidautomation capability
Core Design Contradiction:
Quantity of substanceVSExtent of automation

Solution Approach 1:

The disposable filtration device is designed with multiple integrated functions including filtration, venting, sensor integration, and control capabilities. The device can handle both small and large volume filtrations, and supports both manual and automated operation modes, making it universally applicable across different filtration scenarios and eliminating the need for separate automated systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Area of stationary object

If filter size is increased for large-volume filtration, then filtration area is improved, but device complexity deteriorates

Engineering Contradiction:
Improvefiltration areaVSAvoiddevice complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The filter element is divided into multiple smaller filter units arranged in a grid pattern within the disposable device. Each filter unit can be independently manufactured and then assembled into the complete filtration device. This segmentation allows for large total filtration area while maintaining manufacturing simplicity and enabling modular assembly without increasing overall device complexity.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If manual operation is used for disposable filtration devices, then ease of operation is improved, but process reliability deteriorates

Engineering Contradiction:
Improveease of operationVSAvoidprocess reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The disposable filtration device is equipped with sensors that continuously monitor process parameters such as flow rate, pressure, and filtration status. These sensors provide real-time feedback to an external control system, which can detect deviations from normal operation and automatically adjust or alert operators. This feedback mechanism maintains process reliability while preserving the simplicity of disposable device operation.

Inventive Principle:
Principle #23Feedback
