Solution Overview

Problem

Existing electronic controller modules (ECMs) for sump pumps are independent of the sump pump system, leading to electrical connection issues and are not water-resistant, making them prone to damage during installation or accidental submersion.

Innovation Solution

An integrated electronic controller module within the sump pump electrical cord, featuring a water-resistant housing with sensors, processors, and visual and audible alarms, which eliminates the need for separate electrical connections and provides real-time monitoring and feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If an independent electronic controller module is used, then the sump pump system can be monitored and controlled, but electrical connection issues occur between the pump, switches, and controls

Engineering Contradiction:

Improvemonitoring and control capabilityVSAvoidelectrical connection reliability

Core Design Contradiction:

Extent of automationVSReliability

Solution Approach 1:

The electronic controller module is integrated into the power cord of the sump pump, merging the control function with the power supply component. This eliminates separate electrical connections between the pump, switches, and controls, resolving the connection reliability issue while maintaining automation capability.

Inventive Principle:

Principle #5Merging (Combining)

2Extent of automation

If an independent electronic controller module is used, then the sump pump system can be monitored and controlled, but the module is not water resistant and may be permanently damaged if accidentally dropped into the sump pump pit or basement

Engineering Contradiction:

Improvemonitoring and control capabilityVSAvoidwater damage susceptibility

Core Design Contradiction:

Extent of automationVSObject-affected harmful factors

Solution Approach 1:

The electronic controller module is integrated into the power cord, which is inherently more protected from water exposure compared to independent modules that can be accidentally dropped into the sump pit or basement. The power cord's routing and positioning provide natural protection while maintaining monitoring and control functions.

Inventive Principle:

Principle #5Merging (Combining)

3Extent of automation

If an independent electronic controller module is used, then the sump pump system can be monitored and controlled, but numerous electrical connections must be made between the pump, switches, and controls

Engineering Contradiction:

Improvemonitoring and control capabilityVSAvoidelectrical connection complexity

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The electronic controller module is integrated into the power cord, combining the power supply and control functions into a single unit. This eliminates the need for multiple separate electrical connections between the pump, switches, and controls, significantly reducing installation complexity while maintaining full monitoring and control capability.

Inventive Principle:

Principle #5Merging (Combining)
