Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underwater cleaning devices face issues with debris accumulation at the filtering layer, leading to blocked filtering holes and insufficient water flow into the pump suction assembly, which affects wall and slope climbing performance and user experience.
Innovation Solution
A cleaning device with a filtering assembly that includes a cover part pivotally connected to the filtering box, allowing it to switch between states to cover or expose a flow guiding opening, ensuring adequate water flow to the main water pump, even when the filtering layer is clogged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filtering layer is used to filter debris from water, then the filtering effect is improved, but the filtering holes become blocked when debris accumulates, reducing water flow to the pump
Solution Approach 1:
The patent divides the water flow path into two separate channels: one through the filtering layer and another through the flow guiding opening. This segmentation allows water to flow through multiple paths simultaneously, ensuring that if the filtering layer becomes blocked, water can still reach the pump through the alternative path, thus maintaining productivity while preserving filtering effectiveness
Solution Approach 2:
The flow guiding opening acts as an intermediary alternative path for water flow. When the filtering layer is blocked by accumulated debris, the flow guiding opening serves as a mediator that redirects water flow to the pump, preventing the blockage from completely stopping water circulation and maintaining system operation
2Reliability
If the cover part covers the flow guiding opening to maintain filtering, then water flow through the pump is reduced, but the pump suction assembly cannot generate sufficient pushing force for wall climbing
Solution Approach 1:
The cover part is designed to be movable rather than fixed, allowing it to dynamically adjust its position. It can pivot between covering the flow guiding opening to maintain filtering during normal operation and opening it to expose the opening when additional water flow is needed for wall climbing, thus adapting the system state to different operational requirements
Solution Approach 2:
The water flow path is segmented into two independent routes: through the filtering layer for normal cleaning operation and through the flow guiding opening for enhanced pumping during wall climbing. This segmentation allows the system to optimize for different functions by selectively using each path without compromising the other
3Force
If the cover part is opened to expose the flow guiding opening to increase water flow, then the pushing force for wall climbing is improved, but debris can enter the pump suction assembly
Solution Approach 1:
The flow guiding opening is designed with specific local characteristics including its position, size, and shape that optimize water flow while minimizing debris entry. The opening is strategically located and dimensioned to allow sufficient water passage for pumping power while maintaining a configuration that naturally prevents or reduces debris accumulation and entry into the pump
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the stability and performance of the cleaning device by maintaining sufficient water flow for wall and slope climbing, improving user experience by ensuring consistent operation even when the filtering layer is partially blocked.
Implementation Method 1
When the cleaning device is entirely located underwater, gravity of the adjustment part is greater than a buoyancy force
Implementation Method 2
When the cleaning device is entirely located underwater, a buoyancy force applied to the adjustment part is greater than gravity
