Solution Overview

Problem

Traditional stacked disk-type lenticular filtration systems are bulky, time-consuming to assemble, require expensive and heavy metallic parts, and need skilled operators for proper compression, leading to increased sanitization costs and environmental impact.

Innovation Solution

The introduction of disposable filter capsules with a fluid interconnect that eliminates the need for a separate sanitary housing, reduces part and labor costs, and features a connector with a sealing member and camming members to ensure proper sealing and easy connection of large-diameter filter capsules, reducing the reliance on operator skill and environmental impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional stacked disk-type lenticular filters are used with a sanitary housing and center rod compression system, then proper sealing and filtration function are achieved, but the system becomes bulky, heavy, and complex requiring skilled operator intervention

Engineering Contradiction:
Improvesealing reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system is divided into modular filter capsules that can be independently manufactured and assembled. Each capsule is a self-contained unit with integrated sealing features, eliminating the need for a separate sanitary housing and complex compression system. This segmentation reduces overall system complexity while maintaining sealing reliability through standardized connector designs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sealing features, connector elements, and filter media are merged into a single integrated filter capsule assembly. The connector incorporates sealing members and camming members in one component, eliminating the need for separate sealing elements and compression mechanisms. This merging simplifies the overall system while ensuring reliable sealing through the integrated design.

Inventive Principle:
Principle #5Merging (Combining)

2Strength

If traditional metallic parts and sanitary housing are used, then durability and sealing are achieved, but the system becomes expensive, heavy, and requires extensive sanitization

Engineering Contradiction:
Improvestructural strengthVSAvoidsystem weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The filter capsules are designed as disposable units that can be easily replaced rather than cleaned and reused. This eliminates the need for expensive sanitization processes and heavy metallic components. The disposable nature allows for lighter materials to be used, reducing overall system weight while maintaining adequate structural strength for the filtration function.

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

Solution Approach 2:

The material composition is changed from traditional heavy metallic parts to lighter, more cost-effective materials such as polymers or composites. These materials maintain sufficient structural strength for the application while significantly reducing weight. The parameter change in material selection also enables easier assembly and disposal, reducing operational complexity and environmental impact.

Principle #35Parameter changes

3Manufacturing precision

If a center rod with active follower is used for compression, then proper filter compression is achieved, but the system requires skilled operator training and time for assembly

Engineering Contradiction:
Improvecompression precisionVSAvoidassembly time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The filter capsules are pre-assembled with integrated sealing features and connector elements in a controlled manufacturing environment. The sealing members and camming members are positioned in advance during fabrication, eliminating the need for skilled operator intervention during assembly. This preliminary action ensures consistent compression precision while dramatically reducing assembly time in the field.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The connector design incorporates self-aligning and self-compressing features that automatically ensure proper sealing and compression without requiring skilled operator intervention. The camming members and sealing members are designed to engage automatically during capsule connection, providing consistent compression precision through the self-service mechanism while eliminating the need for trained operators.

Inventive Principle:
Principle #25Self-service

4Quantity of substance

If large diameter disk-type filters are used, then filtration capacity is improved, but connection and sealing become more difficult and require more force

Engineering Contradiction:
Improvefiltration capacityVSAvoidconnection ease
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The connector design shifts the connection interface to a smaller diameter portion of the filter capsule, away from the large diameter filter media area. This dimensional change allows for easier connection and sealing operations on the connector itself, while the large diameter filter capsules maintain their filtration capacity. The sealing action is concentrated at the connector interface rather than requiring force across the entire large diameter.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The sealing members and camming members are concentrated at specific local areas of the connector rather than distributing force across the entire filter capsule. This local quality approach allows for effective sealing and connection at critical points while reducing the overall force required for assembly. The connector design creates localized compression zones that ensure proper sealing without requiring excessive force across the large diameter structure.

Inventive Principle:
Principle #3Local quality
