Fluid Dispensing Rotor and Piston Mechanism for Consistent Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional beverage dispensers often dispense inconsistent amounts of syrup and carbonated water, leading to flavor inconsistencies in the drinks they produce.
Innovation Solution
A fluid dispensing system featuring a rotor and piston mechanism within a housing, where a motor rotates the rotor to align bores and apertures, allowing precise dispensing of predetermined amounts of fluids through a series of stops and seals, ensuring consistent fluid distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional metering device is used to control syrup and carbonated water amounts, then the device structure is simple, but the dispensing consistency deteriorates
Solution Approach 1:
The metering device is segmented into multiple independent components: a rotor with multiple bores, individual pistons for each bore, and separate inlet/outlet conduits. Each piston-bore combination independently meters a specific fluid (syrup or carbonated water), ensuring that the failure or variation in one segment does not affect others, thereby improving dispensing consistency while maintaining manageable complexity through modular design.
2Manufacturing precision
If a rotor and piston mechanism is implemented for precise fluid control, then dispensing precision is improved, but device complexity increases
Solution Approach 1:
Multiple metering functions are merged into a single rotating assembly. The rotor contains multiple bores (at least three) that are simultaneously metered by individual pistons, all controlled by a single motor-driven rotation mechanism. This consolidation achieves precise dosing for multiple fluids (syrup and carbonated water) through one integrated system rather than separate metering devices, improving precision while managing complexity through functional integration.
Solution Approach 2:
The metering process utilizes periodic rotation of the rotor to sequentially position different bores and their corresponding pistons at the inlet and outlet stations. Each complete rotation cycle meters predetermined amounts of multiple fluids in a repeating sequence, enabling precise control through rhythmic, periodic motion rather than continuous adjustment, which simplifies the control mechanism while maintaining high dosing precision.
3Stability of the object's composition
If multiple pistons and bores are used to dispense different fluids, then fluid distribution consistency is improved, but the number of components increases
Solution Approach 1:
The rotor assembly serves multiple functions simultaneously: it houses multiple bores for different fluids (syrup and carbonated water), contains individual pistons for each bore, provides sealing surfaces, and acts as the rotating carrier that sequences all metering operations. This multi-functional design ensures consistent fluid mixture composition by integrating all metering functions into one universal component system, reducing the need for separate dedicated devices for each function.

AI summary
An example apparatus includes a housing including an inlet and an outlet. The example apparatus also includes a rotor defining a bore. The rotor is disposed in the housing. The example apparatus further includes a piston disposed in the bore. A motor is operatively coupled to the rotor to rotate the rotor from a first position to a second position. The bore is to be in fluid communication with the inlet and the outlet when the rotor is in the second position.
