Solution Overview
Problem
Conventional vacuum cleaner robots face difficulties in navigating uneven surfaces, such as transitions from hard floors to carpets or door sills, due to their inability to overcome elevations, resulting in reduced dust pickup efficiency.
Innovation Solution
A vacuum cleaner robot with a height-adjustable floor nozzle that can pivot relative to its base, allowing it to adapt to different floor levels by increasing the distance between the nozzle and the surface, enabling the robot to move onto elevations and maintain effective suction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the floor nozzle is fixed in position relative to the base, then the structure is simple and stable, but the robot cannot overcome elevations on uneven surfaces
Solution Approach 1:
The floor nozzle is made dynamically adjustable relative to the base through a height adjustment mechanism. This allows the floor nozzle to change its position vertically, enabling the robot to adapt to uneven surfaces and overcome elevations such as carpet edges or door sills, while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the base is designed to be height-adjustable, then the robot can overcome elevations, but the overall device complexity increases significantly
Solution Approach 1:
Instead of making the entire base height-adjustable, only the floor nozzle is made locally adjustable. This localized adjustment approach allows the robot to overcome elevations by raising or lowering the floor nozzle independently, while keeping the base structure simple and stable, thereby reducing overall device complexity.
3Productivity
If a rotating brush roller is used for dust pickup, then the structure is simple, but dust pickup efficiency is limited
Solution Approach 1:
The invention combines a rotating brush roller with a motor fan unit to create a hybrid dust pickup system. The brush roller provides initial agitation and guidance of dust particles, while the motor fan unit generates strong suction to efficiently collect dust. This merged approach achieves high dust pickup efficiency while maintaining reasonable structural simplicity.
