Vacuum cleaner device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cordless vacuum cleaners often require users to assume unnatural positions due to unbalanced weight distribution and fixed handle configurations, leading to user fatigue and difficulty in reaching various surfaces, especially vertical ones.
Innovation Solution
A vacuum cleaner device with a rotatable handle unit that can adjust to different angles relative to the suction and collection unit, utilizing a rotation unit that separates the weight of the motor and battery across both sides, allowing for balanced weight distribution and ergonomic use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the motor unit and collection container are positioned in correspondence with the handle to allow dual mode use, then the device can be used as a traditional broom, but the user's arm has to support most of the weight causing fatigue
Solution Approach 1:
The device is divided into separate functional modules: a power supply unit (battery), a motor unit, a collection container, and a handle unit. These modules can be independently positioned and configured, allowing the heavy components to be distributed away from the user's arm while maintaining dual-mode functionality through the modular architecture
2Device complexity
If the handle, motor unit, and collection container are positioned in a fixed manner, then the structure is simple, but the user has to assume unnatural positions to reach various surfaces
Solution Approach 1:
The handle unit is made rotatable relative to the motor unit through a rotation unit, transforming the fixed positioning into a dynamic, adjustable configuration. This allows the user to adapt the device orientation to reach various surfaces while maintaining structural simplicity through the modular design
3Adaptability or versatility
If a hinge is introduced between the dust collection unit and motor unit to allow rotation, then the device can adapt to different positions, but the motor unit is positioned above the handle making the device heavy and difficult to use
Solution Approach 1:
The rotation capability is achieved through a dedicated rotation unit that connects the handle unit to the motor unit, rather than using a hinge between the motor and collection container. This segmentation allows the heavy motor and collection container to remain positioned together away from the user's arm, while the handle remains lightweight and easy to hold
Solution Approach 2:
The rotation unit acts as an intermediary mechanism between the handle unit and the motor unit, enabling angular adjustment without requiring the motor to be positioned above the handle. This intermediary structure transmits the rotational motion while maintaining optimal weight distribution
4Adaptability or versatility
If an electric rotation device is used to connect the handle and suction body, then rotation is enabled, but all weight is concentrated on one side making it uncomfortable for the user
Solution Approach 1:
The device architecture segments the heavy components (motor unit and collection container) from the handle unit, with the rotation unit providing the connection. This segmentation ensures that the battery-powered handle unit remains lightweight and easy to hold, while the motor and collection container are positioned together on the opposite side, creating balanced weight distribution
