Solution Overview
Problem
Laundry treatment apparatuses for drying suffer from noise leakage due to their lightweight plastic bases, which lack sound insulation, and adding a double-layered metallic structure increases weight and corrosion risks.
Innovation Solution
A laundry treatment apparatus with a soundproof panel made of metallic material at the bottom, incorporating a bead structure for enhanced rigidity and a sound absorption material like polyethylene terephthalate (PET) to minimize noise without increasing weight or cost, while maintaining the existing base structure and components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a double-layered metallic structure is used for the base, then sound insulation performance is improved, but weight increases and corrosion resistance deteriorates
Solution Approach 1:
The base is divided into two distinct layers: a plastic base layer providing structural support and a metallic soundproof panel layer providing noise insulation. This segmentation allows each layer to perform its specialized function without the drawbacks of a full metallic construction, achieving sound insulation while maintaining light weight and corrosion resistance.
Solution Approach 2:
The base combines plastic material and metallic material in a composite structure. The plastic layer provides corrosion resistance and light weight, while the metallic panel provides sound insulation. This composite approach resolves the contradiction by integrating the advantages of both materials without the disadvantages.
2Object-affected harmful factors
If a double-layered metallic structure is used for the base, then sound insulation performance is improved, but manufacturing complexity increases
Solution Approach 1:
By segmenting the base into separate plastic and metallic layers with distinct functions, the design simplifies the overall structure compared to a complex full metallic double-layered construction. Each layer can be manufactured independently using optimized processes for that material.
Solution Approach 2:
The metallic soundproof panel is applied locally only where sound insulation is needed, rather than constructing the entire base from complex double-layered metallic structure. This local application reduces manufacturing complexity while achieving the sound insulation goal.
3Weight of stationary object
If the base is made of plastic, then weight is reduced, but sound insulation performance deteriorates
Solution Approach 1:
The composite base structure combines plastic and metallic materials, where the plastic layer maintains light weight and the metallic panel provides sound insulation. This resolves the contradiction by allowing the base to be lightweight overall while still achieving adequate noise insulation through the metallic layer.
Solution Approach 2:
The base is segmented into a plastic structural layer and a metallic soundproofing layer, allowing each material to perform its strength. The plastic provides light weight and structural support, while the metallic panel specifically addresses sound insulation where needed.
