Vacuum Cleaner Wheel Display for Visible Drive State Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners have low visibility of operation states, making it difficult for users to perceive errors or wheel driving states, and battery detachment is inconvenient, leading to potential damage or inefficient cleaning.
Innovation Solution
A vacuum cleaner with a display unit on each wheel to show operation state information, including rotation direction, and a detachable battery with a rear attachment that adjusts the center of gravity for improved stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display unit is provided in the main body, then the operation state can be displayed, but the visibility is low and requires user's excessive concentration
Solution Approach 1:
The display unit is moved from the main body to the wheels, changing the spatial dimension of information display. This allows the display to be positioned at a more visible location that naturally catches the user's attention during operation, eliminating the need for excessive concentration to perceive operation states
2Reliability
If the battery assembly is provided in the cleaner body, then the vacuum cleaner can operate, but it is inconvenient to detach the battery assembly
Solution Approach 1:
The battery assembly is segmented from the main body through a detachable connection structure. This allows the battery to be easily removed and reattached while maintaining secure connection during operation, resolving the contradiction between operational reliability and ease of battery handling
3Extent of automation
If the wheels are automatically driven by a driving device, then the vacuum cleaner moves automatically, but the user may not perceive the driving state of the wheels
Solution Approach 1:
The display unit on the wheels provides real-time feedback about the wheel's driving state, rotation direction, and operation status. This visual feedback mechanism allows users to automatically perceive the driving state without requiring additional attention or concentration
4Loss of information
If the display unit is provided on each wheel, then the operation state information and rotation direction can be displayed, but the device complexity increases
Solution Approach 1:
The display unit is designed as a multi-functional component that simultaneously displays operation state information, rotation direction, and other wheel status data. This universal display approach consolidates multiple information functions into a single component, reducing overall device complexity while maintaining comprehensive information visibility
