Modular Fluid Dispenser with Swappable Bottles and Vacuum Break Port
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand sanitizing dispensers are inflexible in terms of fluid type, positioning, and refill management, as they often require constant monitoring and are limited in their ability to be easily moved or refilled, and lack universal compatibility with different fluids.
Innovation Solution
A modular fluid dispensing system featuring a rigid bottle with a vacuum break port and swappable base units that can be easily refilled and mounted on various surfaces, including walls and floors, equipped with sensors for touch-free operation and LED lighting, and a secure attachment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hand sanitizing dispensers are wall mounted or placed on floor/table, then they can be positioned for use, but they become difficult to move and cannot be relocated to optimal locations
Solution Approach 1:
The dispenser is divided into separate components: a base unit that can be mounted or placed, and a removable bottle assembly. This segmentation allows the bottle to be easily swapped between different locations or dispensers, providing positioning flexibility while maintaining stable installation where needed.
Solution Approach 2:
The mounting system incorporates reversible attachment mechanisms that allow the dispenser to be dynamically repositioned. The base unit can be securely mounted to walls, tables, or floors, yet the modular design enables easy relocation by removing and reattaching the base unit to different surfaces or locations.
2Quantity of substance
If free-standing dispensers are made bulky to contain sufficient fluid, then they can hold adequate hand sanitizing solution, but they become difficult to move
Solution Approach 1:
The fluid storage is separated from the dispensing mechanism. The bottle contains the bulk fluid storage capacity, while the base unit houses the pump and control components. This segmentation allows the bottle to be lightweight and easy to move, yet still provide adequate fluid capacity when installed in the base unit.
Solution Approach 2:
The heavy components (pump, motor, control electronics) are concentrated in the base unit, while the bottle remains lightweight. This local concentration of mass allows the dispenser to be stable when mounted, yet the bottle can be easily replaced or moved without the burden of the entire dispenser's weight.
3Adaptability or versatility
If dispensers use collapsible bags for fluid storage, then they can accommodate refills, but they require constant monitoring and replacement by employees
Solution Approach 1:
The bottle is pre-filled with hand sanitizing solution before installation. The threaded cap with integrated seal and puncture mechanism is pre-configured to automatically initiate dispensing when the bottle is screwed onto the base unit, eliminating the need for manual refill operations and monitoring.
Solution Approach 2:
The dispenser system automatically manages fluid dispensing through sensor-activated pump operation. The vacuum break port automatically allows air entry when fluid level drops, preventing vacuum lock without manual intervention. This self-regulating system eliminates the need for constant employee monitoring and manual refilling.
4Reliability
If dispensers are designed for specific fluid types, then they can optimize dispensing performance, but they lack universal compatibility with different fluids
Solution Approach 1:
The bottle design features standardized threaded caps and seal configurations that are compatible with multiple fluid types. The pump system is designed to handle various viscosities and fluid properties, allowing the same dispenser hardware to reliably dispense different fluids such as hand sanitizer, liquid soap, lotion, or other personal care products.
Solution Approach 2:
The dispensing system can adjust pump parameters (flow rate, pressure, dispensing duration) to accommodate different fluid viscosities and properties. This parameter adjustment capability maintains reliable dispensing performance across various fluid types while preserving universal compatibility.
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 modular system allows for easy refilling, flexible positioning, and universal compatibility, ensuring continuous availability of hand sanitizing solution while providing touch-free dispensing and alerting users when refills are needed, enhancing user convenience and hygiene.
Implementation Method 1
The dispenser may include a vacuum break port to replace the fluid in the bottle during dispensing to prevent formation of a vacuum.
Implementation Method 2
A pump may be used in the dispenser to initiate flow from the bottle and out through a nozzle in response to a command received from a sensor.
Implementation Method 3
The bottle may be installed onto a threaded fastener including a puncturing taper to break the seal of the bottle.
Implementation Method 4
light emitting diodes (LEDs) are provided to convey information to a user, illuminate an area for safety, or for aesthetic purposes
Implementation Method 5
the dispenser uses a light sensor to detect and activate in response to the presence of a hand of a user to enable touch-free operation

AI summary
A modular fluid dispensing system includes a rigid bottle and multiple swappable base units. The modular fluid dispensing system includes a bottle housing to house a rigid bottle, a dispenser to dispense the fluid, and an attachment mechanism to reversibly affix the modular fluid dispensing system to a support structure. The bottle housing includes a threaded fastener to form a seal with the rigid bottle and a puncturing taper to puncture a seal of the rigid bottle. The dispenser includes a pump to initiate flow of the fluid from the rigid bottle and out a nozzle in response to a command signal from a sensor. The dispenser also includes a vacuum break port to allow an external fluid to replace the fluid in the bottle and prevent formation of a vacuum.
