Solution Overview
Problem
Existing robotic vacuum cleaners require users to handle the entire device to replace the suction mouth, making it cumbersome and unhygienic, and there is a need for improved cleaning efficiency based on different floor types.
Innovation Solution
A robotic vacuum cleaner with a fluidically interchangeable suction mouth upstream of the suction opening, allowing users to choose from various suction mouths suited for specific cleaning tasks, such as hard or non-hard floors, with modular design and interchangeable lips for optimized performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the suction mouth is made interchangeable upstream of the suction opening, then the cleaning efficiency for different floor types is improved, but the device complexity increases
Solution Approach 1:
The suction mouth is separated from the main vacuum robot body into an independent, interchangeable component. This segmentation allows the suction mouth to be exchanged based on different cleaning tasks (hard floors vs. non-hard floors) without replacing the entire robot, thus improving adaptability while managing device complexity through modular design.
Solution Approach 2:
The vacuum robot is designed with a universal mounting interface that accepts different types of suction mouths for different floor types. This multi-functionality approach allows a single robot body to perform multiple cleaning functions by simply changing the suction mouth attachment, resolving the contradiction between versatility and complexity.
2Stability of the object's composition
If the entire vacuum robot must be handled to replace the suction mouth, then the structural integrity is maintained, but the ease of operation deteriorates
Solution Approach 1:
The suction mouth is designed as a separable module with a specific mounting interface on the robot body. This segmentation enables users to replace only the suction mouth component rather than handling the entire robot, significantly improving ease of operation while maintaining the structural integrity of the main robot body through the designed interface.
Solution Approach 2:
The suction mouth is extracted as an independent replaceable component from the integrated robot structure. This extraction allows users to easily remove and replace the suction mouth without disturbing the main robot body, resolving the contradiction between maintaining structural integrity and improving operational ease.
3Reliability
If the entire vacuum robot is handled for suction mouth replacement, then the connection stability is ensured, but the loss of time increases
Solution Approach 1:
The suction mouth is segmented as a separate module with a dedicated mounting interface. This segmentation enables quick replacement of the suction mouth without moving the entire robot, reducing the time required for replacement while ensuring connection stability through the designed interface mechanism.
Solution Approach 2:
The mounting interface for the suction mouth is pre-designed and prepared on the robot body, allowing for rapid attachment and detachment. This preliminary preparation of the interface structure enables quick replacements without time-consuming adjustments, resolving the contradiction between connection stability and replacement time.
