Dual-Flow Refrigerator Dispenser Connector for Fast Tandem Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fluid dispensing systems in refrigerators are limited by low flow rates due to in-line filters, requiring additional reservoir tanks that restrict flow when removed, and lack flexibility in dispensing options.
Innovation Solution
A dual outlet fluid dispensing system with a reservoir tank and plumbing tube, featuring a tank dispense valve and connector that allows for dual tandem flow rates, enabling fast or slow dispensing based on user needs, even when the reservoir tank is removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a reservoir tank is used to increase flow rate, then volumetric output is improved, but device complexity increases
Solution Approach 1:
The patent combines the reservoir tank flow path and the plumbing tube flow path into a single connector that merges both streams. This merging allows the system to achieve high volumetric output by combining flows from both sources while maintaining a relatively simple overall device structure through integration rather than addition of separate complex subsystems.
2Reliability
If a seal is added at the tank port to maintain flow when tank is removed, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent removes the seal component from the tank port assembly entirely. Instead of adding a seal to maintain flow consistency, the system is designed to function with or without the reservoir tank present, using the connector's internal geometry to manage flow from the plumbing tube independently when the tank is removed, thereby achieving reliability without the added complexity of sealing mechanisms.
3Adaptability or versatility
If dual outlet configuration is implemented to provide fast and slow flow options, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements adaptability through dynamic flow path configuration rather than fixed dual outlets. The connector's internal geometry allows the flow paths to adapt based on the presence or absence of the reservoir tank and the positioning of the tank dispense valve, providing both fast and slow flow options through a single integrated structure rather than requiring separate fixed outlet configurations.

AI summary
A fluid dispensing system, including a reservoir tank in fluid communication with a tank port; a reservoir tube having a first end in fluid communication with the reservoir tank; a tank dispense valve in fluid communication with the second end of the reservoir tube; a plumbing tube; and a connector having a first input defining a first channel, a second input defining a second channel, and an outlet. The first input is in fluid communication with the tank dispense valve, the second input is in fluid communication with the plumbing tube, and the outlet is positioned proximate the second channel at an output point. The first channel and the second channel are sized to provide a first fluid flow rate from the tank dispense valve to the output point that is greater than a second fluid flow rate from the plumbing tube to the output point.
