Drawer Washer Cabinet Composite Structure for Lower Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drawer type laundry treating apparatuses are heavy, costly to manufacture, and require extensive assembly time due to their metal-based construction, making them inconvenient for users and costly to produce.
Innovation Solution
A laundry treating apparatus with a cabinet comprising a first frame and a second frame made of metal, a base panel made of a lighter non-metal material, and a cover made of metal, where the base panel, supports, and the frames are integrated through injection molding to reduce weight and manufacturing costs, and the use of plastic for upper bodies to further minimize weight and enhance assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the cabinet is made entirely of metal materials (frame and base panel), then the strength and durability are improved, but the weight and manufacturing cost increase significantly
Solution Approach 1:
The cabinet uses a composite construction where the frame is made of metal material for strength, while the base panel is made of nonmetal material (such as plastic) to reduce weight. This composite approach allows the cabinet to maintain structural integrity while significantly reducing overall weight and manufacturing cost compared to an all-metal construction.
2Stability of the object's composition
If the cabinet is made entirely of metal materials, then the structural stability is improved, but the manufacturing cost and assembly time increase
Solution Approach 1:
The cabinet uses a composite construction where the frame is made of metal material for strength, while the base panel is made of nonmetal material (such as plastic) to reduce weight. This composite approach allows the cabinet to maintain structural integrity while significantly reducing overall weight and manufacturing cost compared to an all-metal construction.
3Strength
If metal plates are fixed to metal frames to form the cabinet, then the structural strength is improved, but the assembly time and manufacturing complexity increase
Solution Approach 1:
The cabinet uses a composite construction where the frame is made of metal material for strength, while the base panel is made of nonmetal material (such as plastic) to reduce weight. This composite approach allows the cabinet to maintain structural integrity while significantly reducing overall weight and manufacturing cost compared to an all-metal construction.

AI summary
A laundry treating apparatus includes a cabinet with an outlet, a drawer drawn out from the outlet, and a tub inside the drawer, providing a space for storing water and having an inlet on its upper surface. A drum rotatably mounted inside the tub includes an inlet on an upper surface for receiving laundry inside of the drum. A cabinet includes a first frame made at least in part from metal and including a first outlet, a second frame made at least in part from metal, spaced apart from the first frame along a moving direction of the drawer, and including a second outlet, a base panel made of a nonmetal lighter than metal, fixed to the first and second frames, and forming a bottom surface of the cabinet, and a metal cover fixed to the first and second frames and forming an upper surface and both sides of the cabinet.
