Solution Overview

Problem

Modern refrigeration appliances with ice and water dispensing units often require separate levers for different products, which can complicate user interaction and increase the need for selection icons and tactile switches, occupying valuable user-interface space.

Innovation Solution

An actuating mechanism on the exterior of the appliance that can be moved to multiple positions to trigger the release of different types of products, such as water or ice, from a single dispensing unit, using a switch to send signals to valves controlling product lines, reducing the need for multiple levers and selection icons.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate levers are provided for ice dispensing and water dispensing, then each product can be dispensed independently, but the device complexity and user interface space requirements increase

Engineering Contradiction:
Improveproduct dispensing capabilityVSAvoidnumber of levers and switches
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single actuating mechanism is designed to perform multiple functions by detecting different push positions. The mechanism can identify a first push position for ice dispensing and a second push position for water dispensing, eliminating the need for separate levers while maintaining product versatility

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the ice dispensing lever and water dispensing lever into one integrated actuating mechanism. This single mechanism includes a push button that can be pushed to different positions to trigger different dispensing functions, reducing the total number of components and simplifying the user interface

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple selection icons and tactile switches are added for different products, then product selection capability is improved, but the available user interface space is reduced

Engineering Contradiction:
Improveproduct selection capabilityVSAvoiduser interface space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The actuating mechanism serves as a universal control for multiple products. By detecting the specific push position (first position for ice, second position for water), it provides product selection capability without requiring separate buttons or icons for each product type

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention adds a dimensional aspect to the actuating mechanism by utilizing different push positions in the same physical space. Instead of requiring separate spatial locations for ice and water controls, the system uses positional variation (first position vs. second position) of a single button to differentiate between products

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

An appliance for dispensing product is provided including a storage compartment located within the appliance, a dispensing unit located on the exterior of the appliance including a dispensing outlet, and an actuating mechanism located on the exterior of the storage compartment. The actuating mechanism is configured to be moved from a neutral position to at least a first position and a second position. The first position is configured to trigger a release of a first type of product, and the second position is configured to release a second type of product, respectively, from the dispensing outlet. In one example, a switch can be provided to detect the position of the actuating mechanism, and each position triggers the release of a different type of product from within the appliance.
