Refrigerator having a door
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator door designs often require multiple components for the foaming process, which can lead to leakage and a less integrated user interface and handle operation, compromising the compactness and visibility of the operation center.
Innovation Solution
The integration of a user interface electrical module, handle groove, and concave portion within a shared housing, allowing for a reduced number of components in the foaming process and enhancing the visibility and accessibility of the operation center by positioning them side by side along the handle groove within a visible boundary frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple components are used for the foaming process, then the user interface and handle operation can be implemented, but leakage of foaming liquid occurs and the operation center lacks compactness
Solution Approach 1:
The patent combines the user interface housing, handle housing, and operation center housing into a single integrated housing structure. This merging of multiple housing components into one unified structure eliminates the leakage issues associated with multiple separate components during the foaming process, while also achieving the desired compactness for the operation center.
2Ease of operation
If the user interface electrical module, handle groove, and concave portion are positioned separately, then each component can be implemented, but the operation center lacks visibility and accessibility
Solution Approach 1:
The user interface electrical module, handle groove, and concave portion are integrated into a single operation center housing, positioning them side by side along the depth direction. This spatial integration improves visibility and accessibility while maintaining a compact arrangement that avoids excessive complexity.
Solution Approach 2:
The components are arranged side by side along the depth direction of the handle groove rather than spreading them out in multiple directions. This dimensional organization optimizes the spatial arrangement for both accessibility and compactness.
3Ease of operation
If the handle groove and user interface are made larger, then user convenience is improved, but the door structure becomes more complex
Solution Approach 1:
By integrating the handle groove and user interface into a shared operation center housing, the structure achieves larger dimensions for user convenience while avoiding the complexity that would result from separate housings. The unified structure simplifies the overall door assembly.
4Ease of manufacture
If multiple separate housings are used for user interface and handle, then each function can be implemented, but the foaming process becomes more complex and prone to leakage
Solution Approach 1:
The patent consolidates multiple housing functions into a single integrated housing structure that accommodates the user interface electrical module, handle groove, and concave portion. This reduces the number of separate housings from multiple to one, simplifying the foaming process and eliminating leakage risks associated with multiple component interfaces.
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
This configuration reduces the risk of foaming liquid leakage, provides a more compact and integrated operation center, and allows for a larger length of the handle groove and user interface, improving user convenience and the overall design of the refrigerator door.
