Refrigerator Inner Door Assembly for Full Door-Guard Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerators limit access to all door guards by requiring the main door to be opened, which results in inefficient cool air preservation and restricted access to stored food.
Innovation Solution
A refrigerator design featuring an inner door with a rotating opening and an outer door that can be opened independently, allowing access to all door guards without opening the main door, utilizing injection-molded inner panels with accommodation grooves and extrusion-molded installation members to enhance assembly and minimize cool air release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the main door is opened to access all door guards, then all door guards become accessible, but cool air is released and refrigeration efficiency decreases
Solution Approach 1:
The door system is divided into two independent segments: an inner door providing access to door guards and an outer door for the storage compartment. This segmentation allows the inner door to be opened independently to access door guards without opening the outer door, thus preventing cool air release while maintaining access to stored food.
2Ease of operation
If a subsidiary door is added to access door guards, then access to door guards is improved, but only some door guards are accessible
Solution Approach 1:
The door guards are arranged in multiple dimensions on the inner door surface, allowing all door guards to be accessible when the inner door is opened. The inner door acts as an independent access plane, enabling full access to door guards without requiring access through the outer door or leaving any door guards inaccessible.
3Ease of manufacture
If the inner panel is injection-molded with accommodation grooves, then assembly is enhanced and manufacturing is simplified, but manufacturing precision requirements increase
Solution Approach 1:
The accommodation grooves for installing door guards are pre-formed during the injection molding process of the inner panel. This preliminary action integrates the door guard installation features into the main manufacturing process, eliminating separate assembly steps and reducing the need for post-manufacturing adjustments, thereby simplifying assembly while maintaining reasonable precision requirements.

AI summary
A refrigerator provided with an inner panel molded through injection molding while an accommodation groove in which an installation member is accommodated is formed at the inner panel, and as a gasket is installed at an installation groove of the installation member, the use of a complex mold such as a slide core is minimized while making it easy to install the gasket at the inner panel.
