Pool Cleaner Track Lap Structure Prevents Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pool cleaning robots experience issues with the track coming loose during operation, which affects their reliability and smooth movement on underwater and wall surfaces.
Innovation Solution
A pool cleaning robot with a track lap structure, featuring a wheel with a track lap structure and a first engaging structure, where the track is sleeved outside the wheel and engaged with the first engaging structure, and an anti-detachment structure on the inner surface of the track prevents the track from detaching, forming a limiting structure that fixes the track's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a track is used to drive the pool cleaning robot to move reliably and smoothly, then the robot's movement reliability is improved, but the track may come loose during operation
Solution Approach 1:
The track lap structure features a nested configuration where the track is sleeved outside the wheel, and the anti-detachment structure on the track inner surface is lapped on the track lap structure. This nesting arrangement allows the track to be engaged with the wheel while maintaining a stable, loose-preventing configuration through the overlapping structural elements.
Solution Approach 2:
The track is divided into functional segments: the track lap structure portion that interfaces with the wheel, the anti-detachment structure on the inner surface, and the engaging structures (engaging teeth or grooves) that mesh with the wheel's corresponding features. This segmentation allows each portion to perform its specific function while collectively preventing the track from coming loose.
2Stability of the object's composition
If the track is engaged with the wheel to prevent detachment, then the track position is fixed, but the structure becomes more complex
Solution Approach 1:
The track lap structure merges multiple functions into a single integrated component: it provides the track's structural support, contains the anti-detachment structure, and interfaces with the wheel through engaging structures. This merging reduces the need for separate parts and simplifies the overall assembly while maintaining track position stability.
Solution Approach 2:
The track lap structure serves multiple purposes simultaneously: it acts as the track body, provides engagement interfaces with the wheel through grooves or teeth, incorporates the anti-detachment structure, and maintains the track's positional stability. This multi-functionality reduces the number of separate components needed in the wheel-track system.

AI summary
One or more embodiments of the present disclosure provide a pool cleaning robot with a track lap structure, including a cleaning body and a drive mechanism. The drive mechanism includes: a wheel, the wheel is rotatably arranged on the cleaning body, the wheel includes a track lap structure and a first engaging structure, the track lap structure and the first engaging structure are sequentially arranged in an axial direction of the wheel, so as to form a limiting structure on the wheel or between the wheel and the cleaning body; and a track, the track is sleeved outside the wheel, and at least part of the track is engaged with the first engaging structure, so that the track is driven by the wheel to move, where an inner surface of the track is provided with an anti-detachment structure, and the anti-detachment structure is lapped on the track lap structure. A position of the track is fixed by the cooperation of the anti-detachment structure provided on the inner surface of the track with the limiting structure, thereby avoiding the problem of loose track.
