Solution Overview

Problem

Conventional sprinklers have difficulty adjusting the tightness and rebounding speed of their swing units, leading to uneven water distribution and reduced effectiveness over time, requiring costly and inconvenient replacement of springs.

Innovation Solution

A swing sprinkler design with a main body, driving unit, cover body, inner plate, and action unit allows for adjustable resilient unit tightness and rebounding speed through a mechanism of rotating the action unit to engage positioning ribs, preventing the resilient unit from rewinding and enhancing the sprinkler's spraying variability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a spring is used in the swing unit to provide resilient force for restoration and spraying, then the swing unit can restore and spray when struck by water, but the spring has a fixed elastic coefficient that cannot be adjusted, making it difficult to adjust the tightness and rebounding speed of the swing unit

Engineering Contradiction:

Improveadjustability of tightness and rebounding speedVSAvoidcomplexity of adjustment mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes the previously fixed spring system adjustable by introducing a dynamic adjustment mechanism. The user can rotate the action unit to change the pre-compression amount of the resilient unit, thereby dynamically adjusting the tightness and rebounding speed of the swing unit according to different irrigation needs.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the physical parameter of the spring system by allowing adjustment of the pre-compression amount. By rotating the action unit, the pre-compression amount of the resilient unit is changed, which directly alters the elastic force and rebounding speed, enabling parameter adjustment without replacing the spring.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the spring is used to restore the swing unit, then the swing unit can achieve circular spraying, but the spring becomes fatigued after certain use period, reducing rebounding speed and spraying effectiveness

Engineering Contradiction:

Improvespraying effectivenessVSAvoidservice life of spring

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent enables the user to maintain and restore the spraying effectiveness without professional service or replacement. By rotating the action unit, the user can re-compress the resilient unit to its original tightness, restoring the rebounding speed and spraying effectiveness, making the system self-maintainable.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent applies preliminary compression to the resilient unit during the adjustment phase. By pre-compressing the spring to the appropriate amount before use, the system ensures optimal rebounding speed and spraying effectiveness from the start, and can restore this preliminary compression state after fatigue occurs.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If the swing unit is struck by water to spray, then irrigation is achieved, but the fixed rebounding speed causes uneven water distribution in concentrated planting areas

Engineering Contradiction:

Improvewater distribution effectivenessVSAvoidspraying pattern variability

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent changes the rebounding speed parameter of the swing unit by adjusting the pre-compression amount of the resilient unit. Users can rotate the action unit to increase or decrease the pre-compression, thereby changing the rebounding speed and spraying pattern to match different planting densities and achieve effective water distribution.

Inventive Principle:

Principle #35Parameter changes

Applied Scientific Principles

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 adjustable water spraying patterns from concentrated to scattered, maintaining effectiveness over time without the need for spring replacement, enhancing user convenience and practicality.

Implementation Method 1

a resilient unit (14) is disposed onto the center axis (123)... the resilient unit (14) may be fatigue or if the user wants to adjust the tightness of the swing unit (12), the user can directly rotate the action unit (50) to drive the driving unit (20) and the inner plate (40), so that the driving unit (20) would rotate around the connecting stick (22) and the resilient unit (14) can be adjusted and tightened through the connecting board (23)

AI summary

A swing sprinkler includes a main body, a driving unit, a cover body, an inner plate and an action unit. The tightness of a resilient unit can be adjusted by the user through the action unit, and a secured positioning is formed by the engagement of restricting protruding ribs of the inner plate and positioning protruding ribs of the receiving space to prevent the resilient unit from rewinding after adjustment to effectively adjust the tightness of the resilient unit and swing unit, and increase variability, as well as practicability and convenience of the sprinkler.
