Solution Overview
Problem
Existing spraying apparatuses for irrigation lack the ability to dynamically adjust the shape and size of the liquid beam for varying irrigation needs, typically offering only a fixed pattern of distribution between soft and hard irrigation.
Innovation Solution
A spraying apparatus with a directing device that alters the impacting direction and area on the liquid dispensing element, allowing for multiple states of operation, including a central and larger circular impacting area, enabling both converging and diverging liquid beams, and intermediate shapes, achieved through a combination of a nozzle and deflecting unit within the liquid channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed liquid outlet configuration is used, then the device structure is simple, but the ability to adjust liquid beam shape and irrigation pattern is limited
Solution Approach 1:
The patent implements a directing device with movable components that can change position to alter liquid flow direction. The directing element can be positioned at different locations within the liquid channel to dynamically adjust the liquid beam shape between focused and divergent patterns, enabling adaptability without requiring multiple fixed outlets.
Solution Approach 2:
The directing device serves multiple functions: it can focus the liquid beam for hard irrigation, diverge it for soft irrigation, and potentially create intermediate patterns. This single multi-functional component replaces what would otherwise require multiple specialized outlets or nozzles, achieving versatility while controlling complexity.
2Adaptability or versatility
If a single liquid outlet configuration is used, then the device is easy to operate, but it cannot provide both soft and hard irrigation patterns
Solution Approach 1:
The directing device is designed to be movable or adjustable, allowing the user to change the liquid flow direction by repositioning the directing element. This dynamic adjustment mechanism enables switching between soft and hard irrigation patterns through a single operational action, maintaining ease of use while providing pattern variation.
3Adaptability or versatility
If the liquid impacts a central area of the dispensing element, then a focused liquid beam is produced for hard irrigation, but soft irrigation capability is reduced
Solution Approach 1:
Instead of requiring precise manufacturing of fixed impact areas, the patent uses a movable directing device that can be positioned at different locations within the liquid channel. By changing the directing element's position, the system dynamically controls where the liquid impacts the dispensing element, enabling selection between central impact (focused beam) and distributed impact (divergent beam) without complex manufacturing tolerances.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible irrigation by changing the liquid beam from focused to wide, accommodating different irrigation requirements, enhancing water distribution efficiency and coverage area.
Implementation Method 1
a directing device to direct liquid from the liquid channel in at least one impacting direction onto an or at least one impacting area at the inner side of the liquid dispensing element
