Detachable Ice Discharge Duct for Easier Refrigerator Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The interior of a refrigerator dispenser is difficult to clean due to its non-visible and non-accessible design, making maintenance challenging for users.
Innovation Solution
The dispenser features a multi-section ice discharge duct system with coupling mechanisms that allow for the removal and attachment of sections, enabling easy access and cleaning by positioning parts of the duct system behind and in front of the door surface, along with a button and tray combination device for residue collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the ice discharge duct is designed as a fixed integrated structure, then the structural integrity and simplicity are improved, but the ease of cleaning and maintenance deteriorates due to non-visible and non-accessible interior
Solution Approach 1:
The ice discharge duct is divided into multiple detachable sections (first section, second section, third section) that can be separated from each other. This segmentation allows users to remove and clean each section individually, solving the problem of inaccessible interior while maintaining structural integrity when assembled.
Solution Approach 2:
The coupling mechanisms between duct sections are designed to be dynamically adjustable, allowing the duct to transition between a fixed integrated state for structural stability and a disassembled state for easy cleaning and maintenance.
2Ease of operation
If the ice discharge duct sections are made detachable with coupling mechanisms, then the ease of cleaning and maintenance is improved, but the device complexity increases
Solution Approach 1:
While segmentation inherently increases the number of parts, the coupling mechanisms are designed to be simple and intuitive, requiring minimal assembly steps. This reduces the practical complexity despite the modular structure, as each section can be independently cleaned and reassembled without complex procedures.
3Shape
If part of the ice discharge duct is positioned behind the door surface, then the aesthetic appearance and compact design are improved, but the accessibility for cleaning deteriorates
Solution Approach 1:
By segmenting the duct into sections positioned at different locations (some behind the door surface, some in front), the design maintains its compact aesthetic appearance while allowing front sections to be easily accessed and cleaned without compromising the overall compact structure.
Solution Approach 2:
The detachable coupling mechanisms enable dynamic reconfiguration of the duct sections, allowing users to access and remove sections for cleaning while maintaining the compact integrated appearance during normal operation.

AI summary
A dispenser and a refrigerator including the same are disclosed. The dispenser includes a first section of ice discharge duct that receives ice supplied from an ice supplier, a second section of ice discharge duct that receives the ice guided by the first section, and a third section of ice discharge duct that receives the ice guided by the second section. The third section guides the ice through an outlet positioned in front of a surface of a door of the refrigerator. The dispenser also includes a first coupling mechanism located at the second section and a second coupling mechanism located at the third section. The first and second coupling mechanisms are configured to engage and disengage with each other to enable removal of the third section from the second section and attachment of the third section to the second section.
