Rotating Dispensing Nozzle Angling for Winter Service Liquid Spread
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dispensing devices for liquid substances in winter service vehicles typically achieve limited lateral spread patterns, often covering only one lane and failing to effectively cover wider areas such as parking spaces due to vertical application methods that lead to atomization and reduced range.
Innovation Solution
A dispensing device with a rotating dispensing element and a nozzle arrangement featuring nozzle outlets angled between 90° +/- 30° to the radial direction, aligned parallel or obliquely to the rotation direction, providing a pre-impulse for enhanced spread, allowing for an asymmetrical spread pattern of up to 10 meters or more by accelerating the liquid substance in the desired direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If vertical application method is used, then liquid is applied to the dispensing element, but lateral spread range is limited and atomization occurs
Solution Approach 1:
The liquid is applied to the dispensing element at a specific angle (90° +/- 30° to radial direction, parallel or oblique to rotation direction) before the dispensing element rotates, providing a pre-impulse in the desired dispensing direction. This preliminary angled application prevents atomization and enables the liquid to be distributed over a lateral range of 10 meters or more, resolving the contradiction between limited spread range and atomization harm.
2Area of stationary object
If rotating spreading disc is used, then brine can be discharged, but only one additional lane can be covered satisfactorily
Solution Approach 1:
The nozzle arrangement applies liquid asymmetrically to the rotating dispensing element, with nozzle outlets positioned and angled to create an asymmetrical spread pattern. This asymmetrical application, combined with the rotation direction, enables the liquid to be distributed over a width of 10 meters or more, covering multiple lanes and parking spaces simultaneously, thus resolving the contradiction between coverage area and dispensing efficiency.
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 enables a significantly wider and asymmetrical spread pattern, effectively covering multiple lanes and wider areas, including parking spaces, by optimizing the liquid distribution and preventing atomization, thus improving coverage and efficiency.
Implementation Method 1
The liquid substance to be dispensed experiences, on the one hand, an acceleration in the desired dispensing direction due to the rotation of the dispensing element
Implementation Method 2
