Weed Killing Applicator with Distributing Member for Uniform Fluid Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional weed killing devices using high temperature fluid suffer from non-uniform distribution of fluid pressure and temperature along the applicator chamber, leading to inconsistent application of heat, resulting in some weeds being killed while others survive.
Innovation Solution
Incorporating an elongated distributing member within the applicator chamber with strategically spaced and aligned distribution openings that redirect fluid flow to ensure even distribution of high temperature fluid across the chamber, maintaining consistent temperature and pressure for uniform application through discharge openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional applicator chamber with a single inlet is used, then the device structure is simple, but the fluid distribution uniformity along the chamber length deteriorates
Solution Approach 1:
The single inlet system is segmented into multiple inlets distributed along the applicator chamber. Each inlet supplies high temperature fluid to a specific section of the chamber, ensuring uniform fluid distribution along the entire length. This segmentation resolves the contradiction by accepting increased structural complexity to achieve the required fluid distribution uniformity.
Solution Approach 2:
Different sections of the applicator chamber are provided with locally optimized inlets positioned at specific locations. The inlet configuration is tailored to each section's requirements, with inlets arranged to direct fluid flow appropriately for that local region. This local quality approach ensures uniform fluid distribution while managing structural complexity through targeted rather than uniform modifications.
2Device complexity
If the inlet is positioned centrally and perpendicular to the chamber, then the device structure is simplified, but the fluid pressure and temperature uniformity deteriorates
Solution Approach 1:
The single central inlet is replaced by multiple inlets distributed along the chamber length. Each inlet is positioned to serve a specific segment of the chamber, ensuring that fluid pressure and temperature remain uniform throughout. This segmentation allows the fluid to be introduced at multiple points rather than one, maintaining consistent thermal and pressure conditions along the entire chamber.
Solution Approach 2:
Deflector plates are introduced as intermediary elements between the inlets and the fluid discharge openings. These plates redirect the incoming high temperature fluid flow to ensure even distribution across the chamber cross-section and along its length. The deflector plates act as mediators that transform the inlet flow pattern into a uniform distribution pattern, resolving the contradiction between simple inlet configuration and fluid uniformity.
3Area of stationary object
If fluid discharge openings are provided along the chamber, then weed treatment coverage is improved, but the fluid state consistency deteriorates
Solution Approach 1:
The fluid discharge system is segmented into multiple discharge openings distributed along the applicator chamber. Each opening is positioned to treat a specific section of weeds. The multiple inlets and deflector plates work together to ensure that despite the distributed discharge openings, the fluid maintains consistent state (temperature and pressure) at each discharge point, achieving both wide coverage and fluid consistency.
Solution Approach 2:
The system is designed to create equipotential conditions for fluid pressure and temperature throughout the applicator chamber. By strategically positioning multiple inlets and using deflector plates, the system ensures that all fluid discharge openings operate under similar thermal and pressure conditions. This equipotential approach allows consistent fluid state across all discharge points while maintaining wide treatment coverage.
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
This solution ensures that all discharge openings apply either liquid or vapor at a consistent temperature and pressure, effectively killing weeds uniformly across the treated area.
Implementation Method 1
the distributing member comprises at least one fluid inlet and a plurality of distribution openings in fluid communication with the applicator chamber
Implementation Method 2
applying the high temperature fluid to the weeds through a plurality of fluid discharge openings
Implementation Method 3
the fluid flowing from the discharge openings nearest to the inlet, which has taken the shortest route through the device and is therefore still relatively hot, will evaporate instantly upon exiting the respective opening
