Solution Overview

Problem

Conventional well systems rely on pressure switches that do not provide robust management, control, or protection and require physical inspection for adjustments, lacking remote monitoring and management capabilities.

Innovation Solution

An Internet-enabled well management system with a controller that communicates with a backend system and client devices, enabling remote monitoring, configuration, and control of the well pump and pressure tank, including features like energy-saving options, diagnostics, alerts, and customizable access permissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a pressure switch is used to control the well pump, then the system maintains pressure within a configured range, but the system lacks remote monitoring and management capabilities

Engineering Contradiction:
Improvepressure maintenanceVSAvoidremote monitoring
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

A wireless communication module is introduced as an intermediary between the pressure switch/control system and remote user devices. This module transmits system status data (pressure readings, pump operation state) and receives remote commands wirelessly, enabling users to monitor and control the well pump system from distant locations without adding complexity to the core pressure control function

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The control system is segmented into independent functional modules: a pressure sensing module, a control module, and a wireless communication module. This segmentation allows the pressure maintenance function to operate independently while the communication module provides remote monitoring capabilities, resolving the contradiction by separating these functions into distinct components that can work simultaneously

Inventive Principle:
Principle #1Segmentation

2Device complexity

If physical inspection is required for system adjustments, then the pressure switch provides simple control, but the system lacks protection and management features

Engineering Contradiction:
Improvecontrol mechanismVSAvoidpump protection
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system incorporates feedback mechanisms where sensors continuously monitor pressure levels, pump operation status, and system parameters. This data is processed by the control module to automatically adjust pump operation, provide protection against abnormal conditions (such as excessive pressure or dry running), and communicate system status remotely. The feedback loop enables sophisticated protection features while maintaining simple local control through the pressure switch

Inventive Principle:
Principle #23Feedback

3Productivity

If the pump runs continuously to meet demand, then water supply is adequate, but the pump operational lifetime decreases

Engineering Contradiction:
Improvewater supplyVSAvoidpump lifetime
Core Design Contradiction:
ProductivityVSDuration of action of stationary object

Solution Approach 1:

The pressure switch and control system operate the pump in periodic cycles rather than continuously. The system maintains pressure within a configured range by cycling the pump on and off based on pressure thresholds, which reduces wear and extends pump lifetime while still meeting water supply demands through the pressure tank that stores pressurized water during pump operation

Inventive Principle:
Principle #19Periodic action

AI summary

A well management system provides Internet-enabled monitoring, configuration, and control of a well system that includes a pump (120) and a pressure tank (130). A controller (110) is operatively coupled to the pump. The controller controls the pump based on pressure readings from a pressure sensor (112) to maintain a configured pressure range within the system. The controller can communicate with a management system via a communications network. The management system is further in communication with one or more client devices (160), which may be associated with a homeowner, a service provider, a manufacturer, or the like. Via the management system, the client devices can receive information from the controller and send commands to the controller.
