Refrigerator Drawer Supporting Frame With Elastic Fixer Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerators experience trembling and noise when drawers are inserted or pulled out due to their design, which affects the stability and quiet operation of the appliance.
Innovation Solution
A supporting frame with an elastic connector and fixer mechanism is integrated into the refrigerator's inner case, allowing the frame to be securely installed and guiding drawer movements, reducing trembling and noise through elastic deformation and a fixing groove system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a drawer is formed as a separate part from the inner case, then the drawer can be detached and moved freely, but the drawer trembles from side to side and makes noise during insertion and removal
Solution Approach 1:
A supporting frame is introduced as an intermediary component between the inner case and the drawer. This frame includes guide ribs that engage with grooves on the drawer, providing lateral guidance and stability during movement while allowing the drawer to remain detachable. The supporting frame acts as a mediator that enables both freedom of detachment and operational stability.
2Stability of the object's composition
If a supporting frame is added to guide drawer movements, then drawer stability is improved, but the device complexity increases
Solution Approach 1:
The supporting frame is segmented into modular components: a main frame body, separate guide ribs, and attachment fixers. This segmentation allows for easier manufacturing, assembly, and maintenance while achieving the required guidance function. The guide ribs can be positioned and adjusted independently to provide optimal lateral guidance without requiring a completely rigid complex structure.
3Stability of the object's composition
If the supporting frame is firmly fixed to the inner case, then the supporting frame stability is improved, but the installation process becomes difficult
Solution Approach 1:
The fixers that attach the supporting frame to the inner case utilize elastic deformation properties. During installation, the fixers can be temporarily deformed to facilitate insertion into mounting holes. Once installed, the elastic material provides continuous restoring force that maintains a firm, stable connection. This dynamic approach allows easy installation while achieving firm fixation.
Solution Approach 2:
The fixers change their physical parameters (shape, position) during installation. They are designed to be deformable under installation force, allowing them to be inserted into mounting holes, and then they elastically recover to their original shape, creating a secure mechanical interlock. This parameter change enables both easy installation and firm fixation.
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
The solution effectively reduces drawer trembling and noise during insertion and removal, enhancing the stability and quiet operation of the refrigerator by using an elastic supporter and guide ribs to stabilize the supporting frame within the installation groove.
Implementation Method 1
the fixer being deformed when pressurized by the projection and restored to an original state when the pressure from the projection is released
Implementation Method 2
an elastic connector connecting the guide rib to the insertion projection. The elastic connector may be elastically deformed as the insertion projection is pushed upwards by pressure from the projection

AI summary
Provided is a refrigerator having a supporting frame whose installation structure is enhanced. The refrigerator includes an inner case defining a storeroom and having a projection formed to protrude to the inside of the storeroom, a drawer arranged to be inserted or pulled out from the storeroom, and a supporting frame arranged in the storeroom to guide movements of the drawer, and installed at the projection, wherein the supporting frame includes a fixer arranged on a side of the supporting frame to prevent the supporting frame from deviating from the projection, the fixer being deformed when pressurized by the projection and restored to an original state when the pressure from the projection is released.
