Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If material is sprayed from air in conventional aerial spraying, then material can be dispersed over a wide area, but material cannot be retained at intended place and dispersion state cannot be controlled

Engineering Contradiction:

Improvematerial placement precisionVSAvoidejection device complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The ejection device is segmented into multiple independent ejection units, each with its own biasing unit and guide unit. This segmentation allows independent control of material ejection at different locations and angles, enabling precise control over material dispersion patterns while maintaining manageable device complexity through modular architecture

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The guide units are designed to be swingable, allowing dynamic adjustment of ejection directions. This dynamic capability enables the system to adapt ejection angles in real-time to achieve desired material placement precision and control dispersion states on the ground surface, transforming a static spraying system into a dynamically controllable one

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If material is ejected in fixed direction, then device structure is simple, but material cannot be ejected to desired location

Engineering Contradiction:

Improveejection direction flexibilityVSAvoidguide unit structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The guide units incorporate swingable mechanisms that allow them to rotate and adjust their orientation. This dynamic feature provides ejection direction flexibility, enabling material to be directed toward various desired locations while maintaining a relatively simple base structure that can be scaled or configured based on specific application needs

Inventive Principle:

Principle #15Dynamics
