Solution Overview

Problem

Manual spreading of reagents in swimming pools results in uneven distribution and consumes time and labor due to the need for a circulation system to disperse the reagents, which is inefficient.

Innovation Solution

A liquid storage assembly with a flexible liquid storage unit and a one-way valve liquid filling nozzle that allows for controlled discharge of reagents, integrated with a spreading mechanism to ensure even distribution and reduce manual labor.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual spreading of reagent is used, then labor and time are consumed, but the reagent distribution is uneven

Engineering Contradiction:
Improvereagent distribution uniformityVSAvoidspreading efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The pool robot autonomously performs the reagent spreading task without requiring manual intervention. The robot navigates the pool and automatically dispenses reagent through its spreading mechanism, enabling self-service operation that eliminates manual labor while ensuring uniform distribution through programmed movement patterns

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical spreading with an automated robot system that uses mechanical propulsion and controlled reagent dispensing. The robot employs a spreading mechanism with controlled nozzles and a navigation system to automatically distribute reagent uniformly throughout the pool, substituting human labor with an automated mechanical-electronic system

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If circulation system is used to disperse reagent, then reagent distribution is improved, but time and labor are consumed

Engineering Contradiction:
Improvereagent distribution uniformityVSAvoidspreading time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The robot performs reagent dispensing directly at the source rather than relying on subsequent circulation to distribute the reagent. By pre-positioning the reagent delivery mechanism and actively dispensing it throughout the pool, the system eliminates the time-consuming circulation phase required after manual spreading

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The pool robot autonomously executes the complete reagent distribution process without requiring activation of the pool's circulation system. The robot's integrated navigation and dispensing systems enable it to independently perform the spreading task, eliminating dependency on the circulation system and reducing overall time consumption

Inventive Principle:
Principle #25Self-service
