Pool Cleaner Yaw Navigation for Faster Sidewall Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool cleaners are inefficient and time-consuming when traversing vertical pool walls due to continuous ascending and descending, and struggle to effectively navigate obstacles, leading to suboptimal cleaning of pool surfaces.
Innovation Solution
A pool cleaner equipped with sensors to detect yaw and orientation, a steering module that can independently drive interfacing elements, and a controller to manage cleaning paths with non-vertical yaw segments, allowing for efficient movement along sidewalls while maintaining contact and minimizing turns, and optionally utilizing a jetting module and maneuverable handle for obstacle bypassing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pool cleaners are programmed to climb walls continuously until reaching the water line followed by descent back to the floor, then the pool surfaces can be cleaned, but the cleaning process becomes time-consuming
Solution Approach 1:
The pool cleaner dynamically adjusts its cleaning path based on real-time sensor feedback. The controller modifies the cleaning pattern to include horizontal segments at different elevations, allowing the cleaner to traverse walls more efficiently without continuous ascending and descending, thereby reducing cleaning time while maintaining comprehensive coverage
Solution Approach 2:
The invention introduces horizontal cleaning segments at multiple elevations along the pool wall, adding a horizontal dimension to the traditionally vertical cleaning path. This multi-dimensional approach allows the cleaner to cover wall surfaces more efficiently by moving laterally across walls at different heights rather than repeatedly climbing and descending
2Reliability
If pool cleaners traverse vertical pool walls using continuous ascending and descending, then wall surfaces can be cleaned, but the process is inefficient
Solution Approach 1:
The cleaning system dynamically adapts its motion pattern by incorporating horizontal traversal segments at various wall elevations. The controller receives sensor data and adjusts the cleaner's path in real-time, enabling efficient wall surface coverage through a combination of vertical and horizontal movements rather than repetitive climbing cycles
Solution Approach 2:
The invention maintains continuous cleaning action by introducing horizontal cleaning segments that allow the cleaner to traverse wall surfaces laterally without interrupting the cleaning process. This eliminates idle time during transitions between vertical climbing and descent phases, keeping the cleaning action continuous and productive throughout the operation
3Reliability
If pool cleaners are designed to climb vertical walls, then wall cleaning is achieved, but navigation around obstacles becomes difficult
Solution Approach 1:
The pool cleaner incorporates sensors that provide real-time feedback about obstacles detected on the pool wall. The controller processes this feedback information and dynamically adjusts the cleaning path to navigate around obstacles, enabling the cleaner to maintain wall cleaning coverage while adapting to various wall features such as spot lamps, return jet outlets, and ladders
Solution Approach 2:
The cleaning system dynamically modifies its traversal pattern in response to detected obstacles. The controller adjusts the horizontal and vertical movement segments to create obstacle-bypassing paths, allowing the cleaner to maintain comprehensive wall cleaning coverage while successfully navigating around various wall-mounted features
4Reliability
If pool cleaners perform vertical travelling in imaginary vertical boxes or strips, then wall cleaning is systematic, but the number of turns increases
Solution Approach 1:
The invention replaces the traditional vertical box-strip pattern with a multi-elevation horizontal segment approach. By introducing horizontal cleaning paths at different wall elevations, the system maintains systematic coverage while reducing the frequency of turns needed to transition between cleaning segments, thereby simplifying the overall cleaning pattern
