Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sprinkler deflectors result in significant splashed water during operation, leading to wastage and damage to vegetation and sprinkler components.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a deflecting surface is used to adjust the range of the liquid jet, then the range adjustment function is achieved, but significant splashed liquid is generated causing wastage and damage
Solution Approach 1:
The deflecting surface is segmented into multiple inclined surfaces arranged in sequence. Each inclined surface redirects splashed liquid at different angles, progressively guiding it back toward the liquid jet path rather than allowing it to splash away in random directions. This segmentation reduces liquid wastage while maintaining range adjustment capability.
Solution Approach 2:
The inclined surfaces act as intermediary elements between the liquid jet and the surrounding environment. Instead of the liquid jet directly splashing onto horizontal surfaces or components, the inclined surfaces mediate the liquid flow, redirecting it back into the jet path and preventing harmful splashing.
2Adaptability or versatility
If a deflecting surface is used to change the liquid jet range, then the adjusting function is achieved, but splashed liquid accumulates around the sprinkler causing damage
Solution Approach 1:
The deflecting surface is divided into multiple inclined surfaces that work in sequence. Each surface redirects splashed liquid at progressively different angles, ensuring that liquid is guided back toward the jet path rather than accumulating around the sprinkler head. This segmented approach prevents liquid damage to surrounding vegetation and components.
Solution Approach 2:
The inclined surfaces convert the harmful splashed liquid into a beneficial resource by redirecting it back into the liquid jet path. The splashed liquid, which would otherwise be wasted or cause damage, is instead recovered and reused, improving overall sprinkler efficiency.
3Adaptability or versatility
If a deflecting surface is used to adjust the liquid jet, then range control is achieved, but splashed liquid flows down through sprinkler components causing damage
Solution Approach 1:
The deflecting surface is segmented into multiple inclined surfaces that progressively redirect splashed liquid. This segmentation ensures that liquid flows in a controlled manner back toward the jet path rather than flowing down through internal components, preventing damage and maintaining reliability.
Solution Approach 2:
The inclined surfaces serve as intermediary structures that intercept and redirect splashed liquid before it can flow down through the sprinkler components. This mediation protects internal components from liquid damage while maintaining the range control function.
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
The solution effectively reduces splashed water, improving sprinkler efficiency and protecting components from damage by redirecting splashed liquid back into the main jet, thus enhancing water distribution and reducing maintenance issues.
Implementation Method 1
The guiding element is in contact with the liquid jet to direct splashed liquid from the deflecting surface back into the liquid jet
Implementation Method 2
the guiding element is resiliently biased against the nozzle body and/or a wall element of the holding structure adjacent to the nozzle body
