Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If concentrated substances are shipped in smaller portions, then shipping and storage space is reduced, but handling and dilution accuracy become problematic
Solution Approach 1:
The system pre-fills standardized receiving containers with precise amounts of concentrate before distribution to remote locations. This preliminary action ensures accurate dosing is performed centrally by trained personnel rather than at remote sites, maintaining dilution accuracy while enabling decentralized storage and use.
Solution Approach 2:
The system changes the state of the concentrate from requiring on-site dilution to being pre-diluted in controlled quantities. By transforming the concentrate into pre-mixed solution containers, the system eliminates the need for remote dilution operations while maintaining storage efficiency.
2Ease of operation
If untrained personnel are responsible for dispensing chemicals, then operational flexibility is improved, but safety and accuracy deteriorate
Solution Approach 1:
The system performs all critical dispensing operations in advance at a central location where trained personnel can ensure safety and accuracy. The pre-filled containers are then distributed to untrained personnel for simple, safe handling and application, eliminating complex chemical handling from remote sites.
Solution Approach 2:
The system uses disposable pre-filled containers that eliminate the need for complex, reusable dispensing equipment at remote locations. This simplifies operations for untrained personnel while maintaining safety, as each container is sealed and ready-to-use without requiring handling of concentrated chemicals.
3Ease of operation
If bulk fluids are shipped to facilities, then dispensing simplicity is improved, but storage requirements and space consumption increase
Solution Approach 1:
The system segments bulk fluid into multiple standardized, smaller receiving containers that are pre-filled with precise amounts of concentrate. This segmentation allows facilities to store only the quantities needed for immediate use rather than maintaining large bulk storage tanks, reducing overall storage space requirements.
Solution Approach 2:
The system changes the storage parameter from large-volume bulk storage to multiple small-volume pre-filled containers. This parameter change enables facilities to maintain simpler dispensing operations while dramatically reducing the total storage space required for chemical inventories.
4Volume of stationary object
If concentrates are dispensed for dilution at various locations, then storage space is reduced, but mixing accuracy and consistency deteriorate
Solution Approach 1:
The system performs the mixing action in advance at a central location with controlled conditions and trained personnel. The pre-filled containers contain concentrates that have already been accurately measured and prepared, eliminating variability in mixing accuracy that would occur if dilution were performed at multiple remote locations.
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 system provides precise and consistent mixing of additives with base ingredients, reducing the risk of chemical miscombination, minimizing waste, and preventing theft by controlling dispensing operations through a controller.
Implementation Method 1
The additive can be flowed through the vacuum manifold and into the VBA. In the VBA, the additive can be mixed with water or other base ingredient
Implementation Method 2
As the additive is flowed through the vacuum manifold, vacuum pressure in the pressure manifold can be measured by a pressure sensor
Data Source
AI summary
Systems and methods are disclosed to mix a base ingredient, such as water, with an additive, such as a cleaning concentrate. A dispensing system of the disclosure can include a container filling apparatus. The container filling apparatus can include one or more source containers that contain an additive to be mixed with water or other base ingredient. The container filling apparatus can include a vacuum manifold and a Venturi body assembly (VBA). The additive can be flowed through the vacuum manifold and into the VBA. In the VBA, the additive can be mixed with water or other base ingredient, and output to a receiving container. As the additive is flowed through the vacuum manifold, vacuum pressure in the pressure manifold can be measured by a pressure sensor. A controller can input pressure data from the pressure sensor over the course of a dispense event. Over the course of a dispense event, flow of additive can be varied or modulated based on the pressure data. The flow of additive can be provided, as controlled by the controller, in a sequence of pulses. The length of a pulse, in a dispense event, can be adjusted based on observed pressure data in prior pulses.
