Refrigerator Rack Buffer Members to Reduce Vibration and Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerators with racks for wine bottles experience vibration and noise due to the transmission of vibrations from the compressor and fan through support protrusions, which affects the stability and quiet operation of the appliance.
Innovation Solution
The implementation of buffer members made of elastic materials, such as rubber, are placed on the support protrusions to elastically support the rack, reducing vibration transmission by creating a spaced separation between the rack and the inner sidewalls, using various shapes like straight, L-shaped, and T-shaped buffer members with seating grooves and locking parts to secure the rack in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the rack is directly supported on the support protrusions, then the structural support is strong and stable, but vibration from the compressor and fan is transmitted to the rack generating noise
Solution Approach 1:
The patent introduces buffer members as intermediary elements between the support protrusions and the rack. These buffer members absorb and dampen vibrations while still providing structural support, thereby reducing noise transmission without compromising the strength of the support system.
Solution Approach 2:
The buffer members are pre-installed on the support protrusions before the rack is placed. This beforehand cushioning prepares the support system to absorb vibrations before they can be transmitted to the rack, preventing noise generation while maintaining support integrity.
2Object-affected harmful factors
If buffer members are added to reduce vibration, then noise is reduced, but the device complexity increases
Solution Approach 1:
The buffer member is divided into distinct functional segments: a mounting portion that attaches to the support protrusion, a cushioning portion that absorbs vibrations, and a rack-contacting portion that interfaces with the rack. This segmentation allows each part to perform its specific function efficiently while keeping the overall design simple and modular.
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 buffer members effectively reduce vibration transmission to the rack, enhancing the stability and quiet operation of the refrigerator, ensuring that wine bottles or other items are stored more stably and with reduced noise.
Implementation Method 1
buffer members formed of an elastic material and disposed on the support protrusions to separate opposite side ends of the rack from the support protrusions
