Wireless Vacuum Cleaner Gyro Assembly for Lower User-Sensed Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The user-sensed weight of wireless vacuum cleaners is increased due to the gravity acting on the suction motor, making it inconvenient for users to handle them, and existing devices do not effectively address this issue.
Innovation Solution
A user-sensed weight reduction device is introduced, featuring a rotatable assembly that accommodates motors and batteries, generating angular momentum to reduce the perceived weight of the vacuum cleaner's top portion through a gyro effect, allowing for easier handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the suction motor is disposed on top of the suctioning pipe, then the structural compactness is improved, but the user-sensed weight increases due to gravity acting on the motor
Solution Approach 1:
The patent introduces a counterweight assembly that includes a balance weight disposed opposite to the suction motor across the rotational axis. This balance weight generates a counterbalancing moment that offsets the gravitational torque produced by the suction motor, thereby reducing the user-sensed weight at the top of the suctioning pipe while preserving the compact top-mounted configuration
2Duration of action of moving object
If multiple large-capacity batteries are accommodated for long-term use, then the duration of action is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple batteries (first battery and second battery) into a single integrated battery assembly housed within the handle. These batteries are electrically connected in series or parallel configuration and mechanically integrated with a unified support structure and connection interface, reducing the number of separate components and simplifying the overall device architecture while extending operational duration
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
The device enhances user convenience by reducing the effort required to hold the vacuum cleaner, enabling users with insufficient wrist strength to handle it for extended periods, and allows for long-term use with multiple large-capacity batteries.
