Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the liquid passage is made very thin to achieve fine atomization, then the spray quality is improved, but the manufacturing difficulty increases and clogging risk increases

Engineering Contradiction:
Improveatomization finenessVSAvoidprocessing difficulty
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The liquid passage is divided into two segments: a first liquid passage with a larger inner diameter for bulk flow, and a second liquid passage with a smaller inner diameter for fine atomization. This segmentation allows each passage to be optimized for its specific function, avoiding the need to manufacture an extremely thin continuous passage that is difficult to produce and prone to clogging.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different sections of the liquid passage system have different inner diameters tailored to their specific requirements. The first liquid passage has a larger diameter suitable for its role in transporting liquid, while the second liquid passage has a smaller diameter optimized for fine atomization. This local differentiation of dimensions resolves the contradiction between achieving fine spray and maintaining manufacturability.

Inventive Principle:
Principle #3Local quality

2Manufacturing precision

If the liquid passage is made very thin to achieve fine atomization, then the spray quality is improved, but the clogging risk increases

Engineering Contradiction:
Improveatomization finenessVSAvoidclogging resistance
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The liquid passage is segmented into a first liquid passage with larger inner diameter and a second liquid passage with smaller inner diameter. The first passage serves as a bulk transport channel that is less prone to clogging, while the second passage provides the fine atomization function. This segmentation reduces the overall clogging risk compared to a single thin passage system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system employs different passage diameters at different locations: the first liquid passage has a larger diameter for reliable liquid transport, while the second liquid passage has a smaller diameter for fine atomization. This local optimization ensures that the critical atomization function achieves fine spray quality without requiring the entire passage system to be extremely thin, thereby reducing clogging susceptibility.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If a very fine liquid passage is used in the atomizing core, then the spray delicacy is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improvespray delicacyVSAvoidprocessing complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The liquid passage is segmented into a first liquid passage with larger inner diameter and a second liquid passage with smaller inner diameter. This segmentation allows the atomizing core to achieve fine spray through the second passage while the first passage handles bulk transport with simpler manufacturing requirements, thereby reducing overall manufacturing complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements different passage dimensions at different locations: the first liquid passage has a larger diameter for easy manufacturing and bulk flow, while the second liquid passage has a smaller diameter for fine atomization. This local differentiation enables fine spray delivery without requiring the entire atomizing core to be manufactured with extremely tight tolerances, thus reducing manufacturing complexity.

Inventive Principle:
