Door end closure assembly with integrated user interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigeration appliances lack user-friendly control and information access, with controls often located internally and not easily accessible, failing to meet user demands for customization and functionality.
Innovation Solution
A door end closure assembly with an integrated user interface and handle that allows control of or provides feedback on the appliance's settings, featuring a user interface housed in an endcap with a labyrinth closure to prevent moisture infiltration, enabling users to control temperature, modes, and receive feedback without exposing the compartments to ambient air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If controls are located internally in the food compartments, then the appliance provides basic functionality, but the controls are not easily accessible and users cannot customize settings conveniently
Solution Approach 1:
The user interface is extracted from the internal compartment location and relocated to the external door surface. The door end closure assembly serves as a carrier that houses the user interface components (display, buttons, touch interface) on its outer surface, making them accessible to users without requiring door opening while maintaining separation from the food storage environment.
Solution Approach 2:
The door end closure assembly acts as an intermediary structure between the user interface and the refrigeration compartment. It provides a mounting platform for the user interface while maintaining environmental separation through the moisture barrier layer, allowing control functions to be accessed externally without compromising the sealed compartment environment.
2Ease of operation
If user interface is integrated into the door end closure assembly, then user interaction is improved, but moisture infiltration risk increases
Solution Approach 1:
A moisture barrier layer (flexible film) is introduced between the user interface assembly and the door end closure assembly interior. This thin film barrier prevents moisture and condensation from infiltrating the user interface electronics while allowing the interface to remain accessible on the external surface of the door.
Solution Approach 2:
The user interface assembly is nested within a recessed cavity in the door end closure assembly, with the moisture barrier layer forming an intermediate protective layer. This nested arrangement protects the user interface components from direct exposure to moisture while maintaining their external accessibility for user interaction.
3Adaptability or versatility
If separate doors are provided for freezer and fresh food compartments, then each compartment can be accessed independently, but the door structure becomes more complex
Solution Approach 1:
The door end closure assembly serves multiple functions: it provides structural closure for the door, houses the user interface components, and acts as a mounting platform for controls. This multi-functional design consolidates several elements into a single integrated component, reducing overall structural complexity while maintaining independent compartment access capability.
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
Enhances user interaction by providing accessible control and feedback on refrigeration settings directly on the door, improving user experience while maintaining compartment isolation and reducing moisture ingress.
Implementation Method 1
The board housing has a downwardly extending lip disposed about a periphery of the board housing and configured to be received into the outwardly opening groove of the endcap to provide therewith a labyrinth closure to restrict moisture infiltration into the interface cavity.

AI summary
A refrigeration appliance includes a compartment for storing food items in a refrigerated environment, and a door for engaging with an appliance body and selectively closing the compartment. The door has a front panel, a rear panel, and a door end closure assembly providing an end of the door. The closure assembly includes an endcap extending between the front panel and the rear panel and a user interface engaged with the endcap. The user interface is configured to allow control of or to provide feedback regarding one or more aspects of the appliance to the user. The endcap defines at least a portion of a handle gap configured to receive at least a portion of a user's hand to allow for selective opening of the compartment, and an interface cavity for receiving the user interface. The interface cavity is separated from the handle gap and closed by the user interface.
