Solution Overview
Problem
Existing vacuum cleaners use a single dirt separator for all cleaning tasks, which can be either too large and cumbersome or too small with poor separation efficiency, making certain cleaning tasks difficult.
Innovation Solution
A vacuum cleaner with multiple cleaning tools, each equipped with a different type of dirt separator, such as cyclonic, non-cyclonic, filter, mesh screen, inertial, and gravitational separators, allowing for selection of the best suited tool for specific cleaning tasks, along with varying suction nozzles and dirt-dislodging elements for enhanced performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large dirt separator is used, then dirt capacity and separation efficiency are improved, but weight and ease of operation deteriorate
Solution Approach 1:
The dirt separator is divided into multiple detachable components including a collection chamber, separation mechanism, and housing. This segmentation allows users to detach and empty just the collection chamber without handling the entire cleaning tool, reducing the effective weight during operation while maintaining large dirt capacity.
Solution Approach 2:
The collection chamber is designed as a separate, removable component that can be easily detached from the main body. This extraction of the dirt storage function allows users to remove only the necessary weight (the filled collection chamber) while keeping the separation mechanism and other functional components in place, thereby improving ease of operation without sacrificing dirt capacity.
2Reliability
If a large dirt separator is used, then separation efficiency is improved, but device complexity increases
Solution Approach 1:
The dirt separator employs a segmented design where the collection chamber is separate from the separation mechanism. This modular approach simplifies the overall device complexity by allowing each component to be optimized independently - the separation mechanism maintains high efficiency while the collection chamber simply stores dirt, reducing the complexity of integrating both functions in a single monolithic structure.
Solution Approach 2:
By extracting the collection chamber as a separate component, the patent simplifies the device complexity. The separation mechanism remains relatively simple in structure, and the collection chamber is a straightforward storage container. This separation avoids the complexity of designing a single integrated system that must simultaneously perform both separation and storage functions with optimal efficiency.
3Ease of operation
If a small dirt separator is used, then ease of operation is improved, but separation efficiency and dirt capacity deteriorate
Solution Approach 1:
The dirt separator is segmented into a compact separation mechanism and a detachable collection chamber. The separation mechanism can be designed to be relatively small and lightweight for easy maneuverability, while the collection chamber provides the necessary dirt capacity. This segmentation allows the main body to remain compact and easy to operate, while still achieving high separation efficiency and adequate dirt capacity through the separate chamber.
Solution Approach 2:
By extracting the collection chamber as a separate component, the patent enables the main separation mechanism to be designed for optimal ease of operation with reduced size and weight. The collection chamber, which contributes to dirt capacity, is detached from the operational weight, allowing the cleaning tool to be maneuverable while still providing large dirt capacity when the chamber is attached and filled.
4Weight of moving object
If a small dirt separator is used, then weight is reduced, but separation efficiency deteriorates
Solution Approach 1:
The dirt separator is segmented into a lightweight separation mechanism and a separate collection chamber. The separation mechanism can be optimized for minimal weight while maintaining high separation efficiency through efficient design of the separation elements. The collection chamber, which adds weight, is detachable, allowing users to carry only the lightweight separation mechanism when dirt capacity is not immediately needed, thus improving ease of operation without sacrificing separation efficiency when the chamber is attached.
Solution Approach 2:
By extracting the collection chamber as a separate component, the patent allows the separation mechanism to be designed with minimal weight while maintaining high separation efficiency. The collection chamber, which contributes to overall weight, is removed from the permanent structure, enabling the cleaning tool to operate in a lightweight state when the chamber is detached, while still achieving high separation efficiency when the chamber is attached for tasks requiring dirt collection.
