Problem

Existing ion exchange devices are not functionally reliable and cost-effective for a variety of applications, and often require significant modifications to systems for use with hydraulic and lubricating oils, water-glycol mixtures, and other coolants.

Innovation Solution

A flexible packaging system with a partially filled cavity and opposing end sections of varying permeability, containing ion exchange resin, allows for on-site treatment of fluids with reduced flow resistance and effective ion exchange, while being cost-effective and adaptable to different installation scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a rigid structure with uniform permeability is used for ion exchange devices, then manufacturing precision and structural stability are improved, but adaptability to different fluid types and installation scenarios deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptability to different fluid types
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The packaging is designed as a flexible container that can adapt its shape and permeability characteristics to match different fluid types and installation scenarios. The flexible structure allows the packaging to be configured with varying degrees of permeability in different regions, enabling effective ion exchange for diverse fluids including hydraulic oils, lubricating oils, water-glycol mixtures, and other coolants without requiring major system modifications.

Inventive Principle:
Principle #30Flexible shells and thin films

2Productivity

If the packaging is made fully permeable to fluid medium, then fluid flow and ion exchange efficiency are improved, but retention of active medium and structural integrity deteriorate

Engineering Contradiction:
Improveion exchange efficiencyVSAvoidretention of active medium
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The packaging is designed with non-uniform permeability characteristics, where different regions have different permeability levels. The end sections have higher permeability to facilitate fluid flow and ion exchange, while the jacket section has lower permeability to retain the active medium and maintain structural integrity. This local differentiation of permeability allows the packaging to simultaneously achieve efficient ion exchange and reliable active medium retention.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If the packaging is made flexible and adaptable, then ease of installation and versatility are improved, but manufacturing complexity and cost-effectiveness deteriorate

Engineering Contradiction:
Improveease of installationVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The packaging is segmented into distinct functional sections: end sections with higher permeability for fluid flow and ion exchange, and a jacket section with lower permeability for active medium retention. This segmentation allows each part to be optimized for its specific function while maintaining overall flexibility and ease of installation. The modular design enables the packaging to be manufactured cost-effectively in large quantities while remaining adaptable to different applications.
