Removable Foam Cup Coupling for Spill-Proof Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foam dispensers lack a convenient and spill-proof mechanism for dispensing foam into a removable cup, and they do not allow for easy modification of foam characteristics such as taste, texture, and smell.
Innovation Solution
A foam dispenser with a removable cup that serves as a cap when not in use, which can be rotated to attach to a pumping device for dispensing foam, and includes interchangeable cartridges for modifying foam characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If foam is dispensed into a removable cup, then user convenience and customization are improved, but spillage and preservation issues worsen
Solution Approach 1:
The cup is designed to serve dual functions: as a dispensing receptacle during operation and as a protective cap when not in use. The cup includes an inlet that can be coupled to the pumping device for dispensing, and the same cup can be inverted to cover the container opening for preservation, eliminating the need for separate cap and cup components.
Solution Approach 2:
The cup is designed to fit over the container opening when inverted, creating a nested configuration where the cup serves as both a dispensing component and a protective cover. This nesting arrangement ensures spill-proof operation while maintaining ease of use.
2Adaptability or versatility
If interchangeable cartridges are added for modifying foam characteristics, then adaptability and customization are improved, but device complexity worsens
Solution Approach 1:
The foam modification system is segmented into interchangeable cartridges that can be independently attached and removed. Each cartridge contains specific modifiers (colorants, flavorings, fragrances) that can be selected based on desired foam characteristics, allowing customization without permanently complicating the device structure.
Solution Approach 2:
The cartridges serve as intermediary components between the pumping device and the foam generation process. These removable cartridges introduce modifiers into the foam stream without requiring permanent integration into the device, maintaining simplicity while enabling adaptability.
3Ease of operation
If the cup is designed to rotate and couple to the pumping device, then ease of operation is improved, but manufacturing precision requirements worsen
Solution Approach 1:
The attachment mechanism combines a threaded connection for secure coupling with a rotational motion for user-friendly operation. The inlet of the cup includes threading that mates with the pumping device, allowing the cup to be attached by simple rotation rather than requiring precise alignment, thus balancing ease of operation with manufacturing feasibility.

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 spill-proof operation and allows users to easily change the visual, olfactory, and taste characteristics of the foam by using interchangeable cartridges, enhancing user convenience and customization.
Implementation Method 1
The inlet may also include a porous member, such as a mesh
Implementation Method 2
an air chamber to inject air into the liquid to convert it to foam

AI summary
A foam dispenser may include a container having an interior for storing a liquid, a pumping device positioned in the container for converting the liquid into a foam, and a removable cup. The cup may include an interior to hold the foam, a primary opening for pouring the foam from the cup, and an inlet that is separate from the primary opening. The inlet can be attached to the pumping device during operation of the foam dispenser to receive the foam from the pumping device into the cup. The cup can be detached from the pumping device when the foam dispenser is not in use.
