Nested Cyclone Bin Assembly for Compact Vacuum Hose Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning apparatuses, such as vacuum cleaners, face challenges in design where the cyclone bin assembly is difficult to detach and handle separately from the suction hose, leading to increased size and potential for hose damage during use.
Innovation Solution
A surface cleaning apparatus design featuring a removable cyclone bin assembly with a nested suction hose connector, allowing the cyclone bin assembly to be separated from the suction hose connector, and automatically connecting to the tangential air inlet of the cyclone chamber, reducing the overall size and protecting the hose from impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the cyclone bin assembly is integrated with the suction hose connector, then the apparatus structure is compact, but the cyclone bin assembly becomes difficult to detach and handle separately
Solution Approach 1:
The suction hose connector is divided into two separate components: a fixed portion attached to the main body and a removable portion attached to the cyclone bin assembly. This segmentation allows the cyclone bin assembly to be detached and handled independently while maintaining a compact integrated structure when assembled.
Solution Approach 2:
The removable portion of the suction hose connector is nested within the cyclone bin assembly, with the downstream end of the connector positioned inside the dirt collection chamber. This nesting arrangement reduces overall apparatus size while enabling separate handling of the cyclone bin assembly.
2Ease of operation
If the suction hose connector is exposed on the exterior, then it is easily accessible, but it becomes vulnerable to impact damage
Solution Approach 1:
The suction hose connector is positioned within the protective enclosure of the cyclone bin assembly, which serves as a cushioning structure. This pre-positioning protects the connector from external impacts and damage while maintaining its functional accessibility through the cyclone bin assembly's air inlet.
3Device complexity
If the cyclone bin assembly is permanently attached to the suction hose connector, then the structure is simplified, but the cyclone bin assembly cannot be removed for cleaning or maintenance
Solution Approach 1:
The connection between the cyclone bin assembly and suction hose connector is made dynamic rather than static. The removable portion of the connector allows the cyclone bin assembly to be easily attached and detached, enabling maintenance and cleaning while keeping the overall structure simple.
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
This design enables easier handling and manipulation of the cyclone bin assembly without the suction hose, reduces the apparatus's size, and protects the hose from damage, while maintaining efficient air flow and dirt collection capabilities.
Implementation Method 1
The rotation of the air in the cyclone results in some of the particulate matter in the airflow stream being disentrained from the airflow stream
Implementation Method 2
The rotation of the air in the cyclone results in some of the particulate matter in the airflow stream being disentrained from the airflow stream
