Cantilevered Bracket for Washing Machine Vibration Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machine designs experience vibration and movement issues due to the use of fixed corner brackets, which cause the apron to flex and the machine to 'walk', negatively impacting consumer perception and reliability.
Innovation Solution
A bracket system with a first plate cantilevered from a second plate, where the second plate is fixed to the apron, providing a sturdy connection between the sub-washer unit and the apron while allowing for deflection to reduce vibration transfer, featuring a triangular shape and a cavity for mounting the sub-washer unit's mount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed corner brackets are used to attach the sub-washer unit to the apron, then the sub-washer unit is securely mounted, but the apron flexes and the washing machine moves or walks during operation
Solution Approach 1:
The bracket uses a flexible metal plate structure that can deflect under load. The plate is designed to be flexible enough to allow controlled deflection during washing operations, absorbing vibration and preventing the washing machine from walking, while still providing secure mounting support.
Solution Approach 2:
The bracket changes the physical parameters of the mounting system by using a plate with specific flexibility characteristics. The plate's deflection capability is tuned to allow controlled movement that absorbs vibration energy, transforming the rigid mounting system into one that can dynamically respond to operational forces.
2Object-generated harmful factors
If a flexible bracket is used to reduce vibration, then vibration transfer is reduced, but the mounting strength and rigidity may be compromised
Solution Approach 1:
The metal plate is designed with specific geometric characteristics that provide flexibility for vibration reduction while maintaining sufficient structural strength. The plate's dimensions, thickness, and material properties are selected to achieve the optimal balance between flexibility and strength.
Solution Approach 2:
The bracket employs a composite structure combining the flexibility of a metal plate with the strength of mounting features. The plate can be integrated with other components or materials to enhance both its flexibility and structural strength simultaneously.

Function Achieved in This Case
The bracket system effectively reduces vibration and movement between the sub-washer unit and the apron, enhancing the stability and reliability of the washing machine by providing a robust and compliant connection.
Implementation Method 1
The first plate is cantilevered with respect to the second plate when the second plate is fixed to the apron... effectively reduces vibration and movement between the sub-washer unit and the apron

AI summary
A bracket for mounting a sub-washer unit of a washing machine appliance includes a first plate spaced apart from a second plate along a vertical direction. The first and second plates may be formed from a continuous piece of material. The second plate is fixable to an apron of the washing machine such that the first plate is cantilevered with respect to the second plate when the second plate is fixed to the apron. A related washing machine appliance is also provided.
