Refrigeration water dispensing system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current water dispensers in refrigeration appliances lack efficient methods for controlling and delivering water at varying temperatures, limiting user options for ambient, cold, and mixed water outputs.
Innovation Solution
A water dispensing system featuring a three-way connector and valve actuator that directs water from an inlet source to both an ambient water holding portion and a cold water tank, allowing for the dispensing of ambient, cold, or mixed water temperatures through a three-way water control valve and dispenser actuator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a simple single-tank water dispenser is used, then the device complexity is low, but the temperature control capability is limited
Solution Approach 1:
The water storage system is segmented into two separate tanks: an ambient water tank and a cold water tank. This segmentation allows independent storage of water at different temperatures, enabling the dispenser to provide multiple temperature options (ambient, cold, and mixed) without requiring a single complex temperature control system. The segmentation resolves the contradiction by dividing the storage function while maintaining overall system simplicity.
Solution Approach 2:
The water dispenser achieves multi-functionality by combining two simple tank systems with a mixing mechanism. The system can dispense ambient water, cold water, or any mixture thereof, providing three temperature options from a relatively simple dual-tank architecture. This multi-functional capability improves adaptability without proportionally increasing device complexity.
2Measurement precision
If a dual-tank system with mixing capability is implemented, then the temperature control precision is improved, but the device complexity increases
Solution Approach 1:
The water dispenser incorporates a dynamic mixing mechanism that allows real-time adjustment of the water temperature by varying the proportion of ambient and cold water mixed. The mixing ratio can be dynamically controlled to achieve precise temperature settings, transforming a static dual-tank system into a dynamically adjustable temperature control system. This dynamic capability improves temperature precision without requiring complex refrigeration or heating systems.
Solution Approach 2:
A mixing chamber or mixing mechanism acts as an intermediary between the ambient water tank and cold water tank. This intermediary component combines water from both tanks in controlled proportions, enabling precise temperature control through simple mixing rather than complex thermal management. The intermediary mixing mechanism resolves the contradiction by providing temperature precision through a relatively simple additive process.

AI summary
A water dispensing system for use in a refrigeration appliance comprises a three-way connector operably coupled to an inlet water source and configured to direct incoming water from the inlet water source into an ambient water holding portion and a cold water tank and a water dispenser disposed on a front surface of a refrigeration chamber door. The water dispenser comprises a three-way water control valve configured to dispense water from the ambient water holding portion, the cold water tank, or a combination thereof, an actuator operable between a first position, a second position, and a third position, and a paddle configured to actuate the dispenser.
