Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary fittings fail to produce carbonated liquids with high enough CO2 concentration and desirable jet patterns.
Innovation Solution
A sanitary fitting with a nozzle insert having a guide channel and baffle wall that swirls and expands the carbonated liquid, creating a high CO2 concentration and attractive jet pattern through an outlet opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a conventional nozzle design is used, then the device structure is simple, but the CO2 concentration in the dispensed liquid is insufficient and the spray pattern quality is poor
Solution Approach 1:
The nozzle is divided into separate functional components: a guide channel section and a baffle section. The guide channel directs the liquid flow, while the baffle creates turbulence and enhances CO2 retention. This segmentation allows each component to be optimized for its specific function, achieving high CO2 concentration without excessive overall complexity.
Solution Approach 2:
The baffle element introduces a new spatial dimension to the flow path by creating a perpendicular obstruction. This dimensional change forces the liquid to swirl and creates turbulence, which enhances CO2 concentration retention and spray pattern quality without simply increasing the size of existing components.
2Ease of operation
If the nozzle insert is fixed in the housing, then the manufacturing process is simpler, but the device cannot be disassembled for cleaning or maintenance
Solution Approach 1:
The nozzle is designed as a separable insert that can be removed from the housing. This segmentation allows the nozzle to be detached for cleaning and maintenance while keeping the housing structure relatively simple. The insert can be easily reinserted without complex assembly procedures.
Solution Approach 2:
The nozzle insert is extracted as a separate removable component from the housing. This extraction enables independent cleaning and maintenance of the nozzle without disassembling the entire device, improving ease of operation while maintaining simple manufacturing processes for both the housing and the insert.
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 the dispensing of carbonated liquids with enhanced CO2 concentration and an appealing spray pattern, improving both quality and aesthetics.
Implementation Method 1
the nozzle insert has a guide channel with a first diameter, with which the carbonated liquid can be guided to a baffle wall of the nozzle insert, so that the carbonated liquid can be swirled by the baffle wall
Implementation Method 2
an expansion chamber which is arranged downstream of the nozzle insert, wherein the expansion chamber has a second diameter which is larger than the first diameter of the guide channel
