Leak-Proof Garbage Basket Baffle for Water Surface Cleaning Robots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water surface cleaning robots experience garbage overflow and leakage from the garbage basket when moving backwards or stopping, affecting cleaning efficiency and user experience.
Innovation Solution
A leak-proof garbage basket with a rotatable baffle that closes the inlet when not in use, featuring a material density less than water, an air cavity, or a counterweight to facilitate quick return to the closed position, and a limiting feature to stabilize the baffle's rotation, ensuring the baffle protrudes above the water level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the water surface cleaning robot stops or moves backwards, then the robot can pause for operation or change direction, but garbage overflows from the garbage basket through the inlet
Solution Approach 1:
The baffle is designed as a rotatable component that dynamically changes its position based on water flow direction. During forward movement, water flow pushes the baffle to an open position allowing garbage collection. When stopping or moving backwards, the baffle rotates to a closed position preventing garbage leakage, thus adapting the structure's state to different operational phases
Solution Approach 2:
The baffle utilizes natural water flow and buoyancy forces to automatically rotate between open and closed positions without requiring external control systems. The counterweight and air cavity work together to create a self-actuating mechanism that responds passively to changes in robot motion state, eliminating the need for motors or sensors to control the baffle
2Object-generated harmful factors
If a rotatable baffle is added to the garbage basket inlet, then garbage leakage is prevented, but the device complexity increases
Solution Approach 1:
A counterweight is attached to the baffle structure to provide rotational moment that opposes the buoyancy force. This counterweight mechanism enables the baffle to rotate reliably between positions and maintains stability in the closed position, preventing garbage leakage while using only passive mechanical elements without complex actuators
Solution Approach 2:
The baffle structure incorporates an air cavity in specific locations to generate buoyancy force only where needed. This localized application of buoyancy, combined with the counterweight, creates a balanced system that achieves reliable rotation and positioning with minimal structural complexity

Function Achieved in This Case
Prevents garbage leakage effectively, maintaining cleaning efficiency and enhancing user experience by ensuring the baffle quickly returns to a closed position, even when the robot is stationary or moving backwards.
Implementation Method 1
A density of a material of the at least partial area of the leak-proof baffle is less than a density of water
Implementation Method 2
the leak-proof baffle is provided thereon with an air cavity
Implementation Method 3
The leak-proof baffle is provided thereon with a counterweight, and on a condition that the leak-proof baffle is at the first position, the counterweight is positioned below a rotation center axis of the leak-proof baffle

AI summary
Disclosed herein are a leak-proof garbage basket and a water surface cleaning robot. The leak-proof garbage basket comprises a body with an inlet, where the body is provided thereon with a leak-proof baffle rotatably connected with the body and disposed close to the inlet, when being in a first position, the leak-proof baffle closes at least a partial area of the inlet. The garbage basket has a novel structure where a leak-proof baffle is disposed at the inlet, which can effectively prevent garbage in the garbage basket from overflowing through the inlet of the garbage basket on a condition that the water surface cleaning robot is stopped or moved backwards, and thus accomplish the objective of preventing garbage leakage, guarantee the cleaning effect of the water surface cleaning robot, and improve the user experience.
