Cleaning Robot Cover Hinge Without a Separate Rotating Shaft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleaning robot designs face issues with the limited size and strength of rotating shafts, leading to breakage and inconvenient installation, as well as noise and decoration challenges related to dust box and water tank coverage.
Innovation Solution
A cleaning robot design featuring a rotating component that forms a rotating pair with the machine body's mounting groove, eliminating the need for a separate rotating shaft and allowing for easy installation and reduced noise through a cover that opens and closes, with a fixing component for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotating shaft is used to hinge the dust box cover with the machine body, then the cover can be hinged, but the rotating shaft is prone to breakage due to limited size and high strength requirements
Solution Approach 1:
The patent removes the rotating shaft component entirely from the hinge mechanism. Instead of using a separate rotating shaft that passes through the transfer piece, the invention uses the outer wall of the rotating component itself to form the rotating pair with the mounting groove, eliminating the fragile rotating shaft and its associated through holes.
Solution Approach 2:
The patent combines the function of the rotating shaft with the outer wall of the rotating component. The outer wall directly forms the rotating pair with the mounting groove, merging what were previously separate components (rotating shaft and rotating component housing) into an integrated structure that improves reliability.
2Ease of operation
If a rotating shaft with through holes is used for hinging, then the cover can be connected, but the installation process becomes inconvenient and complex
Solution Approach 1:
The patent eliminates the need to install a separate rotating shaft through multiple holes. By using the outer wall of the rotating component to directly form the rotating pair with the mounting groove, the installation process is simplified to merely positioning the rotating component, removing the complex shaft insertion steps.
3Object-affected harmful factors
If the dust box and water tank are exposed, then the structure is simple, but noise from vibrations is increased and appearance is degraded
Solution Approach 1:
The patent makes the cover serve multiple functions: it acts as a decorative element to improve appearance, functions as a noise reduction component by shielding the dust box and water tank from vibration noise, and maintains structural simplicity. The cover is fixedly connected to the rotating component, integrating these functions into a single component.

AI summary
A cleaning robot includes a machine body, a rotating component, and a cover. The machine body defines a mounting groove. The rotating component includes an outer wall, and at least a part of the outer wall is jointed with the mounting groove to form a rotating pair. The cover is fixedly connected with the rotating component, and the cover is capable of cooperating with the machine body in an opening and closing manner.
