Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool cleaning robots have a complex driving structure and limited cleaning functions, with separate transmission devices for driving wheels and cleaning brushes, restricting their application to only cleaning the pool bottom.
Innovation Solution
A transmission device that integrates a driving member, a first driven member, and a second driven member, allowing a single driving member to drive both a wheel assembly and multiple cleaning members, such as a ground and water surface cleaning brushes, through a system of gears and belts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate transmission devices are used for driving wheels and cleaning brushes, then the driving function is reliable, but the structure becomes complex
Solution Approach 1:
The patent combines the driving member and multiple driven members (first driven member for ground cleaning brush, second driven member for water surface cleaning brush) into a single integrated transmission device. The driving member's output shaft connects to both driven members through gear mechanisms, allowing one motor to power multiple functions simultaneously, thus simplifying the overall structure while maintaining reliable driving performance.
Solution Approach 2:
The transmission device is designed with universal functionality where a single driving member can drive multiple different cleaning members through different transmission paths. The first driven member drives the ground cleaning brush while the second driven member drives the water surface cleaning brush, enabling the pool cleaning robot to perform multiple cleaning functions with one integrated transmission system.
2Manufacturing precision
If separate transmission devices are used for driving wheels and cleaning brushes, then each component can be optimized independently, but the manufacturing cost increases
Solution Approach 1:
By merging the transmission functions into a single integrated device with one driving member and multiple driven members, the patent reduces the total number of motors and transmission components needed. This consolidation lowers manufacturing costs while the gear mechanisms maintain precise transmission ratios for each cleaning function, achieving cost-effectiveness without sacrificing component optimization.
3Device complexity
If the pool cleaning robot only cleans the pool bottom, then the structure is simple, but the cleaning function is limited
Solution Approach 1:
The pool cleaning robot is equipped with multi-functionality through the integrated transmission device that can drive both ground cleaning brushes for bottom cleaning and water surface cleaning brushes for surface cleaning. This universal transmission system allows the robot to adapt to different cleaning needs (pool bottom and water surface) without requiring separate specialized devices, thereby enhancing versatility while maintaining structural simplicity.

AI summary
The present invention relates to the technical field of pool cleaning robots, and in particular, to a transmission device and a pool cleaning robot. The transmission device includes a driving member, a first driven member, and a second driven member. An output end of the driving member is configured to be drivingly connected to a wheel assembly of the pool cleaning robot, so that the driving member is capable of driving the wheel assembly to rotate. The first driven member is drivingly connected to the wheel assembly. An output end of the first driven member is configured to be connected to a first cleaning member of the pool cleaning robot, and the wheel assembly drives the first driven member to rotate, so that the first driven member drives the first cleaning member to rotate. The second driven member is drivingly connected to the wheel assembly. An output end of the second driven member is configured to be connected to a second cleaning member of the pool cleaning robot, and the wheel assembly drives the second driven member to rotate, so that the second driven member drives the second cleaning member to rotate. According to the transmission device, only one driving member is needed to drive the wheel assembly, the first cleaning member, and the second cleaning member, leading to a simple structure. In this way, cleaning functions of the pool cleaning robot are diversified.
