Solution Overview

Problem

Wireless pool cleaners are difficult to remove from water after a cleaning cycle due to the absence of a cord for extraction and lack of communication with the user when submerged.

Innovation Solution

A self-propelled pool cleaner that identifies a removal area near the waterline and stops there, allowing easy retrieval by the user without tools, using onboard sensors and navigation systems to determine the optimal location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If pool cleaners operate autonomously without cabling, then productivity is improved, but loss of information deteriorates due to inability to communicate with user when submerged

Engineering Contradiction:
ImproveproductivityVSAvoidcommunication with user
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The pool cleaner is equipped with communication systems that provide feedback to the user throughout operation. The system transmits status information, cleaning progress, and operational data to the user's mobile device or control interface, enabling two-way communication even when the cleaner is submerged and operating autonomously.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

A wireless communication intermediary (such as a transmitter or communication module on the cleaner and a receiver/app on the user's device) mediates the information exchange between the submerged cleaner and the user. This intermediary system allows data transmission through water and air interfaces, maintaining communication capability without requiring physical cabling.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A self-propelled pool cleaner may be operable in a swimming pool or spa. The self-propelled pool cleaner may identify a removal area in the swimming pool or spa and stop at the removal area. In certain circumstances, the removal area identified by the self-propelled pool cleaner may be in proximity to a waterline of the swimming pool or spa. Optionally, the removal area may be a generally horizontal surface.
