Solution Overview

Problem

Existing immersion treatment systems are inefficient for treating workpieces of different sizes and shapes with varying treatment durations, leading to suboptimal treatment outcomes and increased costs.

Innovation Solution

A treatment station with a treatment container that can be flooded with a treatment fluid, featuring a closing device for access openings, a conveying device for workpiece movement, and installation elements to optimize fluid distribution and minimize fluid volume requirements, allowing for adaptable treatment processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If immersion tanks are used for treating workpieces, then treatment can be performed, but the system is inefficient for workpieces of different sizes and shapes and requires increased costs

Engineering Contradiction:
Improveadaptability to different workpiece sizes and shapesVSAvoidtreatment efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The treatment chamber is designed to be floodable with treatment fluid, transitioning from a static immersion system to a dynamic flooding system. This allows the same chamber to efficiently treat workpieces of varying sizes and shapes by controlling fluid introduction and removal, thereby improving adaptability without sacrificing productivity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the state of the treatment chamber between flooded and empty states to adapt to different treatment requirements. By controlling the presence and volume of treatment fluid, the system can optimize treatment effectiveness for different workpiece types while maintaining high productivity through rapid fluid introduction and removal

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If treatment chamber is flooded with treatment fluid, then comprehensive coverage of workpieces is achieved, but fluid volume requirements increase

Engineering Contradiction:
Improvetreatment coverage qualityVSAvoidfluid volume
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

Installation elements are strategically positioned within the treatment chamber to create localized fluid distribution zones. These elements ensure that treatment fluid is directed precisely where needed on the workpiece surface, achieving comprehensive coverage while minimizing the total fluid volume required in the chamber

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The installation elements are designed to facilitate self-distribution of the treatment fluid throughout the chamber and over the workpiece. This self-distributing mechanism ensures uniform treatment coverage without requiring excessive fluid volume, as the system uses the workpiece geometry and installation element arrangement to guide fluid flow naturally

Inventive Principle:
Principle #25Self-service

3Ease of operation

If access openings are left open for workpiece introduction and removal, then ease of operation is improved, but fluid leakage occurs

Engineering Contradiction:
Improveworkpiece access convenienceVSAvoidfluid sealing
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The access opening is divided into two distinct openings: a first access opening for introducing workpieces and a second access opening for removing workpieces. This segmentation allows the chamber to be sealed between treatment operations while providing convenient access during loading and unloading, resolving the conflict between operational ease and fluid sealing reliability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The closing elements are designed to automatically or pre-positioned seal the access openings before the flooding process begins. This preliminary sealing action ensures that no fluid leakage occurs during treatment, while the dual-opening design maintains operational convenience by allowing workpieces to be introduced through one opening and removed through another

Inventive Principle:
Principle #10Preliminary action
