Solution Overview
Problem
Conventional drawer assemblies in refrigerators require manual force for operation and lack stability during the closing process, resulting in an unsatisfactory user experience.
Innovation Solution
A drawer assembly with a damping reset unit comprising an elastic member and a damping member that allows automatic closing without external force, featuring a telescopic piston rod and locking structure to control the rebound speed and position, ensuring smooth and stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a roller-slideway structure is used for the drawer assembly, then the structure is simple, but manual force is required for operation and stable operation cannot be ensured
Solution Approach 1:
The elastic member (spring) automatically pushes the drawer body back to the closed state without requiring manual intervention. The system serves itself by using the stored elastic potential energy to perform the resetting function, eliminating the need for user effort during the closing process.
Solution Approach 2:
The damping member dynamically adjusts the reset speed of the elastic member through adjustable damping force. This allows the system to transition from a static roller-slideway structure to a dynamic system that can control the speed and smoothness of the drawer movement, ensuring stable operation throughout the closing process.
2Extent of automation
If an elastic member is used to drive the drawer body to reset, then automatic closing is achieved, but the reset speed may be too fast causing vibration and noise
Solution Approach 1:
The damping member acts as an intermediary between the elastic member and the drawer body. It mediates the force transmission by providing adjustable damping that slows down the reset process, reducing vibration and noise while maintaining the automatic closing function. The damping member controls the rate at which the elastic member's force is applied to the drawer body.
3Speed
If the elastic member has high elasticity for fast resetting, then automatic closing speed is improved, but the drawer body may experience sudden movement and potential damage
Solution Approach 1:
The damping member provides dynamic control over the reset speed by adjusting the damping force. This allows the system to maintain high reset speed while ensuring smooth operation throughout the closing process. The damping force can be adjusted to match the elastic force, preventing sudden movements and potential damage to the drawer body or surrounding components.
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 enables the drawer to close automatically without manual force, improving user experience by reducing vibrations, noise, and potential damage, while maintaining smooth operation and stability.
Implementation Method 1
a reset unit (300) which comprises an elastic member (321) that drives the drawer body (1) to reset from an open state to a closed state
Implementation Method 2
a damping member (330) that reduces the reset speed of the elastic member (321)
Implementation Method 3
a piston rod that is telescopic relative to the housing along a push-pull direction of the drawer body and generates damping with the housing when it telescopes

AI summary
A drawer assembly and a refrigerator, the drawer assembly comprising a drawer body, a slideway assembly for pushing and pulling the drawer body, and a damping reset unit matching the drawer body and being arranged on the sliding channel assembly, the damping reset unit comprising an elastic member for driving the drawer body to reset from an open state to a closed state and a damping member for reducing the reset speed of the elastic member. A refrigerator is provided with the drawer assembly. The arrangement of the damping reset unit enables the process of closing the drawer body to not require the application of external force during the entire process, and the arrangement of the damping member makes the rebound process of the drawer body much gentle, avoiding the vibration, noise, and damage that may be produced during rapid rebound.
