Solution Overview
Problem
Existing refrigerator moisture retention systems require complex assembly procedures and non-woven frameworks, which complicate the integration of moisture-permeable structures and can lead to humidity imbalances.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a non-woven framework and frame fixing are used to assemble the moisture permeable film, then the moisture retention effect can be achieved, but the assembly procedure becomes complex and the integration difficulty increases
Solution Approach 1:
The patent integrates the moisture permeable film directly into the storage box structure by forming a hollow cavity within the box body or cover. The regenerated cellulose is contained within this cavity, eliminating the need for separate non-woven frameworks and frame fixing assemblies. This merging of the film support structure into the box itself simplifies the overall assembly while maintaining moisture retention functionality.
Solution Approach 2:
The hollow cavity acts as an intermediary structure that holds the regenerated cellulose moisture permeable film in place without requiring external frameworks. The cavity provides structural support and positioning for the film, serving as a mediator between the film and the box structure, thereby simplifying integration.
2Ease of operation
If a non-woven framework is used to support the moisture permeable film, then the film can be assembled, but the support structure adds unnecessary complexity
Solution Approach 1:
The patent extracts and eliminates the non-woven framework from the assembly by directly incorporating the regenerated cellulose film into the hollow cavity of the storage box. The framework function is taken out and replaced by the cavity structure itself, simplifying the support structure while maintaining film assembly capability.
Solution Approach 2:
The hollow cavity serves multiple functions: it provides structural support for the moisture permeable film, defines the storage space, and enables direct integration of the film without additional frameworks. This multi-functionality eliminates the need for separate support structures, reducing overall device complexity.
3Stability of the object's composition
If the moisture permeable film is assembled with a frame, then the structure can be formed, but the seamless mounting requirement increases process difficulty
Solution Approach 1:
The patent merges the frame structure with the storage box by forming the hollow cavity as an integral part of the box body or cover during the same manufacturing process. This eliminates the need for seamless mounting of separate frames, as the cavity and box are manufactured as one piece, reducing process difficulty while maintaining structural integrity.
Solution Approach 2:
The hollow cavity is pre-formed during the manufacturing of the storage box itself, before the moisture permeable film is installed. This preliminary action of creating the cavity structure during box fabrication eliminates the need for subsequent frame assembly and seamless mounting operations, simplifying the overall manufacturing process.
