Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry treatment apparatuses have a low ability to remove dust and occupy excessive space due to the large dimensions of their bases, which complicates integration with other household appliances.
Innovation Solution
A compact base design featuring a housing with a dust suction assembly that includes a dust collection port and an air return port, allowing for internal circulation of gas to transfer dust from a cleaner to a dust suction assembly, enhancing dust removal efficiency while reducing overall size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a base for laundry treatment apparatus is designed with traditional structure, then it can accommodate the apparatus, but the base occupies excessive space and has large dimensions
Solution Approach 1:
The dust suction assembly is nested within the cleaning cavity of the base, with the dust collector positioned inside the cavity and the dust suction port extending outward. This nested arrangement allows the base to accommodate the dust removal functionality without increasing its external dimensions, effectively reducing the overall volume while maintaining adaptability for integrating with laundry treatment apparatus.
Solution Approach 2:
The dust suction assembly utilizes the vertical dimension by positioning the dust collector at the bottom of the cleaning cavity and extending the dust suction port upward toward the cleaner. This dimensional arrangement optimizes space utilization within the base, allowing compact integration without compromising the ability to connect with laundry treatment apparatus.
2Productivity
If a dust suction assembly is added to the base, then dust removal efficiency is improved, but the structural complexity increases
Solution Approach 1:
The base's cleaning cavity serves dual purposes: it accommodates the cleaner during operation and houses the dust collector for dust storage. The air circulation system also performs multiple functions by guiding air from the dust suction port through the cleaner to the exhaust port, enabling both dust removal and air circulation. This multi-functionality reduces structural complexity while maintaining high dust removal efficiency.
Solution Approach 2:
The dust suction assembly is merged with the base structure by positioning the dust collector within the cleaning cavity and integrating the air circulation pathways. The dust suction port, cleaner, and exhaust port are connected through a unified air flow path, combining dust collection, filtration, and exhaust functions into a single integrated system that reduces overall structural complexity.
3Speed
If the dust collector is positioned close to the dust suction port, then the air circulation path is shortened, but the dust collection effectiveness may be compromised
Solution Approach 1:
The dust suction port is positioned at a specific location on the cleaner that optimizes dust intake, while the dust collector is positioned at the bottom of the cleaning cavity to maximize dust settlement. The air circulation path is designed with appropriate length and configuration to ensure sufficient residence time for dust particles to be drawn into the cleaner and collected, balancing air circulation speed with dust collection effectiveness through localized optimization of component positions.
