Solution Overview
Problem
Existing refrigerator designs face challenges in efficiently adjusting humidity levels and maintaining installation stability due to the connection method of the cover to the beam, which can lead to issues with cover motion control and requires costly replacements if the hanging hook is damaged.
Innovation Solution
A refrigerator design featuring a detachable hanging hook that can be fixed to either the front or rear housing of the beam, allowing for easy replacement of the hook without altering the beam structure, and an installation mechanism that ensures stability and ease of assembly, including a clamping system for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hanging hook is fixed to the beam using a permanent connection method, then the installation stability is improved, but the ease of repair deteriorates because the entire beam must be replaced when the hook is damaged
Solution Approach 1:
The connection system is divided into separate components: the beam, the hanging hook, and a detachable connection mechanism. This allows the hook to be replaced independently from the beam structure, resolving the contradiction between installation stability and ease of repair.
Solution Approach 2:
The connection between the hanging hook and beam is made dynamically adjustable through a detachable mechanism that provides stable connection during use but allows easy disconnection for replacement. The connection can be engaged or disengaged as needed, transforming a static permanent connection into a dynamic reversible one.
2Ease of repair
If the hanging hook is made detachable for easy replacement, then the ease of repair is improved, but the reliability of the connection deteriorates
Solution Approach 1:
The connection mechanism transitions from a static permanent connection to a dynamic reversible connection that maintains full structural integrity when engaged. The detachable design includes locking features that ensure the connection is as reliable as permanent connections during the operational phase.
Solution Approach 2:
The hanging hook is designed as a replaceable component that can be easily swapped out when worn or damaged, while the main beam structure remains intact. This allows the inexpensive hook to be replaced rather than replacing the entire expensive beam assembly.
3Stability of the object's composition
If the hanging hook is fixed to span across the connection slit between front and rear housings, then the structural stability is improved, but the device complexity increases and installation becomes more difficult
Solution Approach 1:
Instead of requiring the hanging hook to span the entire connection slit between front and rear housings, the connection mechanism is localized to specific engagement points. The hook connects to the beam structure at discrete locations without needing to bridge the gap between housings, simplifying the overall structure.
Solution Approach 2:
The hanging hook connection is extracted from the beam structure as a separate detachable component. This allows the hook to be installed and removed independently without affecting the beam's internal structure or the connection between front and rear housings, reducing device complexity.
Applied Scientific Principles

Function Achieved in This Case
Facilitates control over the cover's motion, allows for convenient installation and removal of the hanging hook, and maintains installation stability even if longitudinal distances change, reducing the need for costly beam modifications and ensuring reliable humidity adjustment.

AI summary
A refrigerator includes a box body having a storage compartment and a beam spanning a front end of the box body. The beam includes a front housing, a rear housing and a heat-insulation material located in a chamber delimited by the front housing together with the rear housing. A cover is located in the storage compartment. A hanging hook is configured to hang and connect a front end of the cover. The hanging hook includes an installation portion to be inserted into the beam in a forward and backward direction. The hanging hook and the beam can be conveniently installed in and removed from the refrigerator, and if the hanging hook is damaged, only the hanging hook needs to be replaced.
