Solution Overview

Problem

Existing fluid-conducting systems face issues with water accumulation, leading to corrosion, conductivity changes, and reduced service life due to both free and dissolved water, with existing dewatering devices being ineffective for dissolved water removal.

Innovation Solution

A dryer cartridge with a receiving chamber containing a drying agent, where the fluid flows through a wall surrounding the chamber, ensuring contact with the agent for effective removal of dissolved water, and optionally incorporating a filter medium and bypass system for enhanced performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional dewatering device with a small portion of hygroscopic material is used, then the device structure is simple and easy to manufacture, but it can only absorb free water at the bottom of the tank and cannot remove dissolved water effectively

Engineering Contradiction:
Improvewater removal effectivenessVSAvoiddevice structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The device is divided into multiple functional sections: a receiving chamber for the drying agent, a flow-through wall with specific flow patterns, and a connection head with connection opening. This segmentation allows each component to perform its specific function efficiently while maintaining overall system reliability for removing both free and dissolved water.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flow-through wall is designed with porous or permeable characteristics that allow fluid to pass through while contacting the drying agent in the receiving chamber. This enables the removal of dissolved water through the wall structure itself, enhancing water removal effectiveness without requiring complex additional components.

Inventive Principle:
Principle #31Porous materials

2Reliability

If the receiving chamber wall is made flow-through to enable fluid contact with drying agent, then dissolved water removal is improved, but the structural integrity and sealing complexity increase

Engineering Contradiction:
Improvedissolved water removalVSAvoidwall structure and sealing
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The flow-through wall is implemented locally in specific sections where fluid contact with the drying agent is most effective, rather than making the entire chamber wall permeable. This localized approach enables dissolved water removal while maintaining structural integrity and simplifying sealing requirements in other areas.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The flow-through wall acts as an intermediary structure that mediates between the fluid containing dissolved water and the drying agent in the receiving chamber. It allows selective passage of fluid while maintaining separation between the fluid environment and the drying agent containment, enabling effective dissolved water removal without compromising structural integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If a connection opening is added to the connection head for fluid communication, then fluid flow and drying effectiveness are improved, but the sealing requirements and manufacturing complexity increase

Engineering Contradiction:
Improvefluid processing efficiencyVSAvoidsealing and assembly
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The connection head is designed with multi-functionality, serving both as a mounting interface for the dryer cartridge in the housing wall and as a fluid communication pathway through the connection opening. This universal design enables fluid processing efficiency improvement while consolidating multiple functions into a single component, reducing overall manufacturing complexity.

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