Spiral-Guided Ice Maker Water Damper for Overflow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic ice makers in cooling appliances often experience water overflow and splashing, leading to malfunctions and physical damage due to limited user intervention and the formation of ice near or on the ice maker.
Innovation Solution
A cooling appliance equipped with a conical water damper above the ice maker, featuring a spiral guide and a collapsible design, along with a heater around the water supply pipe to prevent ice blockage, minimizes water overflow and splash by creating a vortex and directing water flow effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If water is supplied to the ice maker via a pipe, then the ice maker can be automatically filled with water, but water overflow and splashing occur causing malfunctions and physical damage
Solution Approach 1:
A water damper is introduced as an intermediary component between the water supply pipe and the ice maker. The damper includes a conical body with a spiral guide that controls water flow, preventing overflow and splashing while maintaining automatic operation. This mediator structure resolves the contradiction by enabling automation without the harmful water overflow effects.
2Reliability
If a water damper is placed above the ice maker to guide water flow, then water overflow is prevented, but the device complexity increases
Solution Approach 1:
The water damper is constructed from flexible silicone material, allowing it to be collapsible and reversible. This flexible shell design prevents water overflow while maintaining simplicity through material properties rather than complex mechanical structures. The flexibility enables the damper to adapt to different orientations without additional components.
Solution Approach 2:
The damper features a conical shape with a spiral guide formed as a curved protrusion on the inner surface. This curved geometry naturally guides water flow in a vortex pattern, preventing overflow without requiring complex mechanical guidance mechanisms. The spiral curvature efficiently directs water flow using geometric principles rather than additional components.
3Adaptability or versatility
If the water damper is made collapsible and reversible, then it can be used in both hemispheres, but the manufacturing precision requirements increase
Solution Approach 1:
The damper is made from flexible silicone material that can be collapsed and reversed without damage. This flexibility allows the same damper unit to be installed in either hemisphere by simply flipping it, with the spiral guide automatically orienting correctly. The material flexibility compensates for the lack of precise manufacturing tolerances required for rigid reversible mechanisms.
Solution Approach 2:
The damper transitions from a static rigid structure to a dynamic flexible structure that can change orientation. The collapsible and reversible design allows the damper to adapt its configuration based on installation orientation, achieving hemisphere compatibility through dynamic reconfiguration rather than precision-manufactured fixed structures for each hemisphere.
4Reliability
If a heater is coiled around the pipe to prevent ice blockage, then pipe reliability is improved, but energy consumption increases
Solution Approach 1:
Instead of heating the entire water supply system, a heater is applied only to the critical section where ice blockage is most likely to occur. This partial heating approach prevents pipe blockages while minimizing energy consumption by limiting the heated area to only what is necessary for reliable operation.
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
The solution effectively prevents water overflow and ice accumulation near the ice maker, ensuring stable operation and reducing the risk of malfunctions, with the reversible and collapsible water damper accommodating both hemispheres and the heater preventing pipe blockages.
Implementation Method 1
A guide is provided in the form of a protrusion on the inner surface the ice maker. The guide forms a spiral in a first direction which helps forming a vortex in the first direction
Implementation Method 2
a heater is coiled around the pipe so as to prevent blockage of the pipe by gradual formation of the ice inside the pipe
