Robot vacuum cleaner incorporating a detachable hand vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot vacuum cleaners are limited in their ability to access and clean raised surfaces such as stairs, shelves, and walls, requiring a separate handheld vacuum cleaner for these tasks, and their airflow performance is not optimal.
Innovation Solution
A robot vacuum cleaner design that integrates a handheld vacuum cleaner with a mobile base, where the handheld vacuum cleaner has its own rechargeable batteries for independent use and shares power with the mobile base when engaged, optimizing airflow performance and simplifying the power supply system by eliminating batteries from the mobile base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile base incorporates batteries for autonomous operation, then the robot vacuum cleaner can operate independently, but the device complexity and manufacturing cost increase
Solution Approach 1:
The handheld vacuum cleaner's battery system serves dual purposes: it powers the handheld unit during individual use and simultaneously powers the mobile base when docked together. This multi-functional design eliminates the need for separate batteries in the mobile base, reducing device complexity while maintaining autonomous operation capability.
Solution Approach 2:
The patent merges the power supply systems of the handheld vacuum cleaner and mobile base into a single integrated battery system. The electrical connectors establish a shared power circuit where the handheld unit's batteries supply both units when engaged, simplifying the overall power supply architecture.

3Reliability
If a mouthpiece with brush roller is added to the mobile base, then the suction quality improves, but the device complexity increases
Solution Approach 1:
The patent removes the complex mouthpiece with brush roller from the mobile base design. Instead, the handheld vacuum cleaner's nozzle directly engages with the mobile base's suction opening, achieving effective dust pickup without the additional complexity of an integrated brush roller system in the base.
4Adaptability or versatility
If the handheld vacuum cleaner is designed for individual use with separate batteries, then it can operate autonomously, but the power supply system becomes more complex
Solution Approach 1:
The handheld vacuum cleaner's battery system serves dual purposes: it powers the handheld unit during individual use and simultaneously powers the mobile base when docked together. This multi-functional design eliminates the need for separate batteries in the mobile base, reducing device complexity while maintaining autonomous operation capability.
