Solution Overview

Problem

Sump pumps experience wear and tear due to frequent cycling, and there is a need for effective monitoring and control systems to prevent potential failures and maintain optimal operation, especially when not in routine use.

Innovation Solution

An apparatus comprising a housing with a switch, an arm, and a rod, where the arm and rod move between positions to actuate the switch, with a counter to track usage and a secondary float for backup monitoring, allowing remote control and monitoring through a server and user computing device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the sump pump is cycled on and off frequently to respond to fluid level changes, then the pump can effectively maintain fluid levels, but the switch experiences increased wear and reduced lifespan

Engineering Contradiction:
Improveswitch lifespanVSAvoidpump cycling frequency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies preliminary action by implementing a delay mechanism that prevents immediate pump cycling. When the float switch triggers pump activation, a timer component introduces a predetermined delay period before the pump can be reactivated, even if the fluid level condition remains unchanged. This preliminary timing action reduces the frequency of switch operations and extends switch lifespan while still maintaining effective fluid level control over time.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the sump pump runs continuously to prevent fluid accumulation, then fluid levels are maintained, but energy consumption increases and pump lifespan decreases

Engineering Contradiction:
Improvefluid level controlVSAvoidpump energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action through intermittent pump operation based on fluid level conditions. The float switch mechanism allows the pump to run only when fluid reaches a predetermined level, then stops when the level recedes. This periodic on-off operation maintains reliable fluid level control while minimizing energy consumption compared to continuous operation, as the pump activates only when necessary rather than running constantly.

Inventive Principle:
Principle #19Periodic action

3Reliability

If monitoring components are added to track pump operation and provide alerts, then pump maintenance can be improved, but device complexity increases

Engineering Contradiction:
Improvepump maintenanceVSAvoidmonitoring system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies feedback through a monitoring system that tracks pump operation cycles and provides alerts when maintenance is needed. A microcontroller or programmable logic controller counts pump activations and monitors operational parameters, then communicates maintenance status to users via LED indicators, display screens, or remote communication interfaces. This feedback mechanism improves pump maintenance reliability by enabling proactive service while adding only moderate complexity through standard electronic monitoring components.

Inventive Principle:
Principle #23Feedback

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution reduces wear on the switch, provides reliable monitoring and control, alerts users to potential issues, and ensures the sump pump operates correctly even when not in regular use, extending its lifespan and maintaining fluid levels effectively.

Implementation Method 1

The arm magnet includes first and second opposed surfaces and an edge surface. The rod carries a float and a rod magnet. The rod magnet includes a facing surface. As the rod moves from the first rod position to the second rod position, the edge surface of the arm magnet is configured to move across the facing surface of the rod magnet, thereby moving the arm from a first arm position in which the arm does not actuate the actuating tab to a second arm position in which the arm actuates the actuating tab

AI summary

An exemplary apparatus includes a switch, an arm, and a rod. The switch is housed by a housing and includes an actuating tab. The arm is housed by the housing and carries an arm magnet. The arm magnet includes first and second opposed surfaces and an edge surface. The rod carries a float and a rod magnet. The rod is movable between a first rod position and a second rod position at which the rod magnet is in the housing. As the rod moves from the first position to the second position, the edge surface of the arm magnet is configured to move across a facing surface of the rod magnet, thereby moving the arm from a first arm position in which the arm does not actuate the actuating tab to a second arm position in which the arm actuates the actuating tab.
