Solution Overview

Problem

Existing devices for dispensing solid compounds into liquids require human intervention or a pre-existing liquid circulation zone, limiting their autonomy and adaptability.

Innovation Solution

A floating, energy-autonomous device that regulates the flow rate of dissolved solid compounds based on sensor measurements and wireless communication signals, allowing it to dispense chlorine or bromine into liquids without a pre-existing liquid circulation zone, using a circulation circuit, pump, power supply, and control module to optimize delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a device uses a pre-existing liquid circulation zone for dispensing solid compounds, then the dissolution rate can be controlled, but the device cannot be used in locations without such circulation zones

Engineering Contradiction:
Improvelocation flexibilityVSAvoidcirculation system requirement
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary pump system that creates its own local circulation zone around the dispensing device. This mediator component enables the device to function independently without relying on pre-existing pool circulation systems, thereby achieving location flexibility while managing complexity through a dedicated circulation module.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The dispensing device is designed with universal applicability by integrating a self-contained circulation system that can operate in various pool configurations regardless of existing circulation infrastructure. The device performs multiple functions: dispensing solid compounds, creating local circulation, and adapting to different installation locations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Extent of automation

If manual control mechanisms are used for adjusting dissolution rates, then device complexity is reduced, but human intervention is required for adaptation

Engineering Contradiction:
Improveautomatic dissolution rate controlVSAvoidcontrol system complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent implements automatic control through feedback mechanisms that monitor dissolution rates and adjust dispensing parameters accordingly. Sensors detect the state of the liquid medium and provide feedback to the control system, which automatically adjusts the pump operation and compound release rate to maintain optimal dissolution conditions without human intervention.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The device is designed to self-regulate its operation by automatically adjusting dissolution rates based on real-time conditions. The integrated control system monitors and adjusts parameters without requiring external manual control, enabling the device to serve itself and adapt to changing conditions autonomously.

Inventive Principle:
Principle #25Self-service

3Productivity

If high dissolution rates are used for shock chlorination, then treatment effectiveness is improved, but energy consumption increases

Engineering Contradiction:
Improvedissolution rateVSAvoidpump energy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent employs dynamic adjustment of the circulation pump operation to match the required dissolution rate. The system can operate at high speeds when rapid dissolution is needed for shock treatment, and automatically reduces speed during maintenance phases. This dynamic operation optimizes the balance between productivity and energy consumption based on real-time treatment requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device implements periodic operation patterns with distinct high-intensity phases for shock chlorination followed by lower-intensity maintenance phases. This periodic action allows the system to achieve high dissolution rates only when necessary, thereby reducing overall energy consumption while maintaining treatment effectiveness during critical periods.

Inventive Principle:
Principle #19Periodic action
