Refrigerator Drawer Guide Structure for Lateral Shake Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerator drawer type storage spaces with roller members often experience right and left shaking phenomena when their width does not match the refrigerator's main body, leading to inconvenience during drawing in and out.
Innovation Solution
Incorporating shaking prevention members between receiving and fixing members, which include rollers that perform rolling motions to guide and stabilize the drawer's movement, preventing lateral shaking and ensuring smooth sliding in and out operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If drawer type storage spaces are made wider to increase storage capacity, then storage space is improved, but right and left shaking phenomenon occurs causing operational problems
Solution Approach 1:
The patent introduces guide members as intermediary components between the drawer and the refrigerator body. These guide members include shaking prevention members that mediate the interaction between the wide drawer and the fixed structure, preventing lateral shaking while allowing smooth drawing and pushing operations.
Solution Approach 2:
The shaking prevention members are designed to preemptively counteract the lateral shaking force before it can affect drawer operation. By providing opposing reactive forces through the guide members, the system prevents the harmful shaking motion that would otherwise occur during drawer manipulation.
2Ease of operation
If roller members are used to enable drawer movement, then ease of operation is improved, but right and left shaking phenomenon occurs reducing reliability
Solution Approach 1:
The patent divides the support function into multiple independent guide members positioned at different locations along the drawer. Rather than relying on a single roller member, the system segments the support function across multiple contact points, each providing localized guidance and shaking prevention.
Solution Approach 2:
The guide members serve as intermediary components between the roller members and the refrigerator body structure. These intermediaries transmit and control the forces between moving and stationary parts, ensuring stable operation while maintaining ease of movement.
3Adaptability or versatility
If drawer width does not correspond to refrigerator main body width, then adaptability is improved, but shaking phenomenon occurs affecting stability
Solution Approach 1:
The guide members are designed with universal functionality to accommodate drawers of various widths. The shaking prevention members can adapt to different drawer dimensions while maintaining their stabilizing function, making the system versatile for different drawer configurations.
Solution Approach 2:
The guide members provide dynamic adaptation to different drawer widths through their geometric design. The shaking prevention members automatically adjust their positioning and contact points based on the drawer width, maintaining stability without requiring precise pre-matching of dimensions.
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 prevents right and left shaking, making the drawer easier to use, extending the life span of rollers, and improving the reliability and performance of the drawer's sliding mechanism, especially for wider drawers.
Implementation Method 1
a first roller mounted on the receiving member and performing a rolling motion along the fixing member when drawing in and out the receiving member; a second roller mounted on the fixing member and performing a rolling motion along the receiving member
Implementation Method 2
shaking prevention members provided between the receiving member and the fixing members and performing a rolling motion by contacting the receiving member or the fixing members when drawing in and out the receiving member to prevent a right and left shaking phenomenon

AI summary
Disclosed is a refrigerator comprising a main body provided with a freezing chamber and a refrigerating chamber; a receiving member provided to be able to be drawn in and out to the main body and receiving foods; fixing members disposed on right and left sides of the receiving member and supporting the receiving members; entrance guide members provided between the receiving member and the fixing members and guiding sliding movement of the receiving members; and shaking prevention members provided on right and left sides of the receiving members and preventing a right and left shaking phenomenon of the receiving members. With the present invention, a shaking phenomenon is prevented in drawing in and out a receiving member, so convenience of use may thereby be improved.
