Telescopic Nebulizer Lance for Hedge Mist Dispersal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nebulization systems for mosquito control face issues with mist retention within hedges, leading to ineffective dispersal of anti-mosquito additives, and also suffer from aesthetic and safety concerns due to protruding nozzles and tubes.
Innovation Solution
A nebulizer with an extensible conduit that allows the nebulization nozzle to change distance from the delivery mouth, enabling the nozzle to be repositioned within a hedge in a discreet contracted configuration and extended for effective mist dispersal, while incorporating a drain valve for efficient fluid management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If nebulization nozzles are installed within a hedge, then the aesthetic appearance is improved and safety is enhanced, but the mist is retained within the hedge resulting in poor dispersal of anti-mosquito additives
Solution Approach 1:
The nebulization nozzle is made movable relative to the hedge through an extensible conduit that can change its position between retracted (for aesthetic appearance) and extended (for effective mist dispersal) configurations, allowing the system to adapt dynamically to different operational requirements
2Productivity
If nebulization nozzles are installed protruding outside the hedge, then the dispersal effect is improved, but aesthetic appeal deteriorates and safety concerns arise due to collision risks
Solution Approach 1:
The system transitions from a static protruding configuration to a dynamic one where the nozzle can be extended only when needed for dispersal and retracted when not in use, maintaining both aesthetic appearance and safety while preserving dispersal effectiveness when required
3Productivity
If nebulization nozzles are installed protruding outside the hedge, then the dispersal effect is improved, but the ability to prune the hedge deteriorates due to damage risks to the system
Solution Approach 1:
The extensible conduit allows the nebulization nozzle to be retracted within the hedge during pruning operations, protecting the system from damage while allowing the hedge to be pruned, and then extended when needed for dispersal operations
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 enhances the dispersive effect of anti-mosquito additives, improves aesthetic appeal by hiding nozzles within the hedge, ensures safety by avoiding collisions, and allows for hedge pruning without damage to the system, while maintaining effective nebulization.
Implementation Method 1
a spring aimed at influencing the conduit towards the contracted rest configuration
Implementation Method 2
forcing the working liquid to pass through a very narrow orifice of the nebulization nozzles at generally higher pressures, for example of the order of 10-100 bar

AI summary
Outdoor and/or indoor nebulizer (1) comprising a delivery mouth (2), a nebulization nozzle (3) for dispensing a mist of nebulized working liquid, and a conduit (4) therebetween; said conduit (4) being extensible within a contracted rest configuration and an extended operating configuration to change the distance of the nebulization nozzle (3) from the delivery mouth (2). The nebulizer further comprises a drain valve (6) arranged upstream of the conduit (4) to act as an anti-drip device and simultaneously eliminate residual overpressures in the body of the nebulizer (1).
