Solution Overview
Problem
Existing handheld vacuum cleaners have weight distribution issues, leading to user discomfort and increased risk of wrist injury, along with airflow inefficiencies due to the placement of heavy components and long air passage lengths.
Innovation Solution
The suction motor is positioned ahead of the handle, and the battery is placed behind it, with the suction motor located above the dust separation unit, minimizing the air passage length and preventing airflow discharge towards the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the airflow generator and power supply are disposed right over and under the handle, then the center of gravity concentrates on the handle, but this causes inconvenience for user and may injure the user's wrist
Solution Approach 1:
The airflow generator is repositioned from a vertical arrangement (over the handle) to a horizontal arrangement (in front of the cyclone separator along the longitudinal axis), changing the spatial dimension of component layout. This dimensional shift moves the center of gravity forward, distributing weight away from the user's wrist while maintaining compact overall structure.
2Device complexity
If the airflow generator is disposed behind the cyclone, then the structure is simplified, but the air channel becomes necessarily long causing large flow loss
Solution Approach 1:
The conventional arrangement of placing the airflow generator behind the cyclone separator is inverted by positioning it in front of the cyclone along the longitudinal axis. This inversion shortens the air channel length and reduces the number of flow direction changes, thereby minimizing airflow loss while maintaining structural simplicity.
3Volume of moving object
If the airflow generator is disposed right over the handle, then the structure is compact, but the discharged air directly touches the user's hand
Solution Approach 1:
The airflow generator is extracted from its position directly over the handle and relocated to a position in front of the cyclone separator. This extraction removes the source of discharged air from proximity to the user's hand, eliminating the harmful effect of hot or high-velocity air contacting the user while preserving device compactness through optimized spatial arrangement.
