Refillable Spray Head With Electric Pump for Creamy Product Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging and dispensing devices for liquid or semiliquid products are limited by the need for pressurized propellant gas, which restricts their use to liquid products only and prevents refilling when the gas supply is exhausted, and cannot handle creamy products due to insufficient pressure for expulsion.
Innovation Solution
Incorporating a miniature electrical transfer pump between the first and second reservoirs, powered by an electrical power supply and controlled by control means, allows for product transfer and refilling of the movable spray head, enabling operation without propellant gas and accommodating a wider range of product viscosities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pressurized propellant gas is used to transfer product from the second reservoir to the first reservoir, then liquid products can be dispensed, but the device cannot operate when gas supply is exhausted and cannot handle creamy products
Solution Approach 1:
The patent replaces the propellant gas system with an electric pump system. The pump uses electrical power to drive a rotor that creates centrifugal force to transfer product from the second reservoir to the first reservoir, eliminating the need for pressurized gas and enabling continuous operation without gas supply limitations.
Solution Approach 2:
The patent uses centrifugal pumping action where the rotating impeller creates hydraulic flow to move the product. The pump utilizes fluid dynamics principles to transfer creamy or viscous products through the coupling means, replacing the pneumatic pressure system with a hydraulic-mechanical system.
2Ease of operation
If a valve system is interposed between the second reservoir and the first reservoir for product transfer, then product can be controlled to flow, but the device becomes complex and cannot refill when gas is exhausted
Solution Approach 1:
The patent replaces the complex valve system with a simpler electric pump system. The pump uses electrical control to manage product flow, eliminating multiple mechanical valves and their associated complexity while maintaining controlled refilling capability through electronic switching and pump control.
Solution Approach 2:
The device enables self-refilling by automatically activating the pump when the spray head is coupled to the base. The system self-regulates the refilling process without requiring manual valve operation, reducing mechanical complexity while improving ease of operation.
3Quantity of substance
If propellant gas pressure is used to expel product, then liquid products can be dispensed, but creamy products cannot be expelled due to insufficient pressure
Solution Approach 1:
The patent replaces gas pressure expulsion with electric pump-driven expulsion. The pump uses mechanical rotation to directly move product from the reservoir, providing sufficient force to expel creamy and viscous products that cannot be handled by propellant gas pressure alone.
Solution Approach 2:
The pump creates hydraulic flow through centrifugal action, generating the necessary pressure and flow to move products of varying viscosities. This hydraulic-mechanical system replaces the pneumatic system, enabling handling of higher viscosity creamy products.
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 device to function independently of propellant gas, allowing refilling and expanding its application to semiliquid and creamy products by ensuring continuous operation and efficient product transfer.
Implementation Method 1
a miniature electric pump, known as the transfer pump, powered by an electrical power supply means and controlled by control means is interposed between the first and second reservoirs to allow product to be conveyed through the coupling means
Implementation Method 2
a substantially cylindrical intermediate spool which is slideably mounted and is elastically returned by a return spring in the bore of the female member, said spool being able to move between a rest position to which it is returned elastically in the bore of the female member
