Refillable Syrup Bin with Self-Closing Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverage machines require large single-use bags for syrups, leading to minimum quantity purchases and increased costs, especially for low-volume users, limiting the availability of fresh and diverse ingredients.
Innovation Solution
A beverage dispenser with refillable ingredient bins featuring a self-closing silicone seal and twist-lock mechanism to prevent leakage, allowing for direct addition and dispensing of ingredients without bags, and accommodating a sloping bottom and removable lid for efficient ingredient flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If large single-use bags are used for syrups, then the beverage machine can be filled with ingredients, but minimum quantity purchases are required and costs increase for low-volume users
Solution Approach 1:
The syrup storage system is segmented into reusable bins that can be filled with small quantities of syrup multiple times, replacing the single large bag system. This allows low-volume users to purchase smaller amounts of syrup repeatedly rather than being forced to buy large quantities in single-use bags.
Solution Approach 2:
The invention replaces expensive single-use large syrup bags with reusable bins and small refillable syrup containers. The reusable bin infrastructure is invested once, then small, inexpensive syrup refills are used repeatedly, eliminating the need to continuously purchase expensive large single-use bags.
2Productivity
If large single-use bags are used for syrups, then the beverage machine can operate, but availability of fresh and diverse ingredients is limited
Solution Approach 1:
The reusable bin system serves multiple functions: it can store different types of syrups and ingredients, accommodate various container sizes and types, and work with different syrup viscosities. This universal system replaces the single-function large bag design, enabling greater ingredient diversity and freshness.
Solution Approach 2:
The system allows changing parameters such as syrup type, volume, and frequency of replacement. Users can switch between different syrup varieties and adjust refill frequencies based on usage patterns, enabling greater adaptability and ingredient diversity compared to the fixed large bag system.
3Ease of operation
If refillable ingredient bins are used, then single-use bags are eliminated and ingredient management improves, but leakage may occur when bins are disconnected
Solution Approach 1:
The bin outlet incorporates a self-closing seal that automatically closes when the bin is disconnected from the beverage machine, preventing leakage without requiring manual intervention. The seal mechanism self-activates based on the disconnection event, providing reliable leakage prevention while maintaining ease of operation.
Solution Approach 2:
The self-closing seal is positioned and configured to close the bin outlet before any leakage can occur during disconnection. This preemptive sealing action cushions against the potential harmful effect of leakage, ensuring that syrup does not spill when the bin is removed for refilling.
4Reliability
If a self-closing seal is added to the bin outlet, then leakage is prevented during disconnection, but device complexity increases
Solution Approach 1:
The sealing function is extracted as a separate, dedicated component (self-closing seal) that can be independently designed and maintained. This modular approach allows the seal to be optimized for reliability while keeping the rest of the bin structure simple and easy to manufacture.
Solution Approach 2:
The self-closing seal acts as an intermediary element between the bin outlet and the external environment. It provides a simple mechanical interface that automatically seals the outlet when disconnected, adding minimal complexity while effectively preventing leakage without requiring complex control systems or mechanisms.
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
Eliminates the need for single-use bags, enabling fresher and more diverse ingredient usage by allowing direct refill and dispensing, reducing costs and improving ingredient management for users.
Implementation Method 1
Each refillable ingredient bin includes a self-closing seal located at a bin outlet to prevent leakage of the beverage ingredients from the bin outlet when the refillable ingredient bin is disconnected from the mixing portion
Implementation Method 2
the ingredient bin has a sloping bottom to direct ingredients in the ingredient bin toward the bin outlet
