Front-Load Washer Raised Tub Structure for Easier Laundry Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Front loading type laundry treating machines have a low entrance, making it inconvenient for users to load and unload laundry, and existing solutions do not effectively address the need for improved user convenience and inner spatial efficiency.
Innovation Solution
A laundry treating machine design that includes a housing with a raised entrance space between the washing tub and the installation surface, supported by a lightweight upper base that only supports the tub and its components, allowing for a movable body to be inserted for easier access, and anti-vibration members to reduce noise and vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entrance is lowered to improve user convenience for loading and unloading laundry, then ease of operation is improved, but the machine occupies more floor space and inner spatial efficiency deteriorates
Solution Approach 1:
The patent raises the entrance vertically by positioning the washing tub above the installation surface and providing a support structure underneath, allowing users to load/unload laundry at a higher, more convenient level without increasing the machine's footprint on the floor
2Ease of operation
If a heavy support structure is used to raise the washing tub to improve user convenience, then ease of operation is improved, but device complexity and weight increase
Solution Approach 1:
The support structure is divided into modular components including an upper base, lower base, and side frames that can be assembled separately, reducing manufacturing complexity and allowing for easier installation while still providing the necessary structural support to raise the tub
Solution Approach 2:
The patent employs composite construction combining metal frames with plastic or composite panels for the bases, achieving the required strength and rigidity to support the tub while keeping the overall weight and complexity manageable
3Object-affected harmful factors
If vibration isolation components are added to reduce noise and vibration, then harmful factors are reduced, but device complexity increases
Solution Approach 1:
Anti-vibration members are positioned as intermediary elements between the support structure and the washing tub, acting as a mediator that absorbs and dampens vibrations generated during washing operations, thereby reducing noise transmission to the surrounding environment
Solution Approach 2:
The anti-vibration members are integrated into the support structure design itself rather than being separate add-on components, allowing the structure to provide both mechanical support and vibration isolation functions through its inherent design
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 design enhances user convenience by allowing easy loading and unloading without bending, improves inner spatial efficiency, and reduces noise and vibration through the use of anti-vibration members and a lightweight structure.
