Refrigerator Ice Dispenser With Single-Switch Ice Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current refrigerator dispensers require two separate steps and switches to select and dispense ice types, increasing complexity and component count, which can lead to higher costs and operational difficulties.
Innovation Solution
A single switch operation is used to select and dispense both ice types, with an integrated ice crushing device and automatic resetting switches, reducing the number of components and simplifying the control panel, while allowing for external switch placement to prevent accidental activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate switches are used for selecting and dispensing ice types, then the ice dispensing function is complete, but the device complexity and number of components increase
Solution Approach 1:
The patent combines the ice type selection function and the dispensing activation function into a single switch. When the user presses this integrated switch, it simultaneously selects the desired ice type (ice cube or crushed ice) and activates the dispensing process, eliminating the need for separate selection and activation switches.
Solution Approach 2:
The single switch is designed to perform multiple functions: it serves as both the selection mechanism for different ice types and the activation trigger for dispensing. The switch can be pressed once for ice cubes or twice for crushed ice, providing universal control for both dispensing modes through one component.
2Adaptability or versatility
If two separate switches are used for selecting and dispensing ice types, then the ice dispensing function is complete, but the ease of operation decreases due to multiple steps
Solution Approach 1:
The patent merges the selection step and the activation step into a single pressing action. Users no longer need to first press a selection button and then press a separate start button; instead, a single press of the integrated switch accomplishes both tasks simultaneously, making the operation simpler and faster.
3Ease of operation
If switches are placed inside the dispensing chamber, then the control is accessible, but the external container may accidentally touch and activate the switch
Solution Approach 1:
The patent extracts the switch from the dispensing chamber interior and relocates it to the exterior surface of the refrigerator door. This positioning ensures that the switch is easily accessible to users for intentional operation, while simultaneously preventing accidental contact by containers placed in the dispensing chamber, as the switch is now outside the chamber boundary.

AI summary
An operation method of a refrigerator, wherein the refrigerator comprises a storage space, an ice container (3) in the storage space (2), a dispensing apparatus (4) for dispensing ice from the ice container (4) to outside of the storage space (2), the dispensing apparatus being configured to dispense at least two types of ice; and a switch (5,6) for selecting the type of ice to be dispensed,characterized in that the method comprising: when the switch (5,6)is activated, the dispenser apparatus (4) dispenses the type of ice selected by the actuation of the switch (5,6), responsive to actuation of the switch (5,6).
