Solution Overview

Problem

Filter press systems in industries like food and pharmacy face contamination issues due to products being pressed into seal grooves, leading to reduced seal effectiveness and frequent, costly cleaning needs.

Innovation Solution

A plate component with a firmly integrated seal made from a different thermoplastic material, eliminating grooves and providing an escape volume to distribute pressure, ensuring a continuous, contamination-free surface for enhanced sealing without gaps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If seals are installed in grooves on filter plates, then sealing effectiveness is improved, but contamination occurs when products are pressed into the grooves

Engineering Contradiction:
Improvesealing effectivenessVSAvoidcontamination
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts and eliminates the groove structure from the filter plate design. Instead of placing seals within grooves, the seals are now integrated directly into the plate component without any groove structures, thereby removing the source of contamination while maintaining sealing functionality

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The seal and plate component are merged into a single integral structure. The seal is firmly connected to the plate component, forming an integrated system where the seal extends from the contact surface into the plate volume, eliminating the need for separate groove installations and reducing contamination risk

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If seals are installed in grooves, then sealing is achieved, but regular cleaning and seal removal are required

Engineering Contradiction:
ImprovesealingVSAvoidcleaning frequency
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The seal and plate component are merged into a single integral structure through firm connection, eliminating the need for separate installation and removal operations. This integration allows the seal to remain in place during cleaning operations, reducing maintenance downtime

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integral design allows the filter press system to be cleaned without removing the seal, enabling the sealing system to serve itself during maintenance operations. The seal remains functional while the surrounding surfaces are cleaned, eliminating the need for specialized seal removal and reinstallation procedures

Inventive Principle:
Principle #25Self-service

3Reliability

If seals are installed in grooves, then sealing is provided, but cleaning the grooves is expensive

Engineering Contradiction:
ImprovesealingVSAvoidcleaning cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The groove structure is completely extracted from the design, eliminating the complex cleaning operations required for groove maintenance. Without grooves, standard cleaning procedures can be applied to the entire surface without requiring specialized tools or procedures for confined spaces

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The integral seal design simplifies the overall system structure, reducing the need for expensive specialized cleaning equipment and procedures. The simplified geometry allows for more economical cleaning operations while maintaining sealing effectiveness

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Object-affected harmful factors

If a continuous surface is provided without grooves, then contamination is prevented, but seal integration complexity increases

Engineering Contradiction:
Improvecontamination preventionVSAvoidseal integration
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The seal and plate component are merged into a single integrated unit with the seal firmly connected to the plate. This integration achieves the continuous surface goal while managing complexity through unified manufacturing processes for the combined structure

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The plate component and seal are made from different thermoplastic materials with different elastic moduli, creating a composite structure that achieves both the continuous surface requirement and manageable integration complexity through material property optimization

Inventive Principle:
Principle #40Composite materials

AI summary

The present invention relates to a plate component for a filter press system made of a first thermoplastic material having at least one seal made of a second thermoplastic material for sealing a pressure-loaded chamber area, wherein the seal is fixedly connected to the plate component, and wherein the second thermoplastic material preferably has a different elasticity module, particularly a lower elasticity module, than the first thermoplastic material. The seal is provided, at least partially, in an area of a contact surface of the plate component for attaching the plate component to a further component of the filter press system, and extends, at least in part, into the plate component in a direction that is vertical to the contact surface.
