Vacuum Cleaner Wheel Display for Visible Driving and Error Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners have low visibility for operation state display, making it difficult for users to perceive errors or driving states, which can lead to damage or ineffective cleaning, and battery replacement is inconvenient due to the integrated battery assembly.
Innovation Solution
A vacuum cleaner with a display unit on the wheel that shows operation state information, including power status, rotation direction, and obstacle detection, using sensors and a controller to control the display and driving unit, and a detachable battery with improved mounting for easier access and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display unit is provided in the main body, then the structure is simple, but the visibility of operation state is low and user perception is difficult
Solution Approach 1:
The display unit is moved from the main body to the wheel, changing the spatial dimension of the display location. This allows the display to be positioned where it can be easily seen by the user during operation, significantly improving visibility without adding complex internal structures to the main body.
Solution Approach 2:
The wheel serves as an intermediary carrier for the display unit. Instead of directly integrating the display into the main body, the patent uses the wheel as a mediating element to hold and position the display unit, achieving better visibility while maintaining structural simplicity.
2Ease of operation
If the battery assembly is integrated in the cleaner body, then the structure is stable, but the battery replacement is inconvenient
Solution Approach 1:
The battery assembly is segmented from the main body structure, allowing it to be independently removed and replaced. This segmentation enables users to easily access and replace the battery without disassembling the entire cleaner, improving operational convenience while maintaining overall structural integrity through proper connection interfaces.
3Productivity
If the wheels are automatically driven by a motor, then the cleaning performance is improved, but the user cannot perceive the driving state
Solution Approach 1:
The display unit on the wheel provides real-time feedback about the driving state to the user. It shows information such as motor operation status, battery level, and driving mode, allowing users to monitor and understand the automatic driving process while maintaining high cleaning performance.
