Solution Overview

Problem

Existing sump pump systems often rely on a single float switch for controlling the pump's operation, which can lead to failure if the switch malfunctions, resulting in incomplete liquid removal from the sump.

Innovation Solution

The implementation of a dual connector assembly and two vertical float switches, each with a unique configuration and power connection, ensures that the sump pump can operate even if one float switch fails, by providing a redundant mechanism for powering the pump.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single float switch is used to control the sump pump, then the device complexity is reduced, but the reliability decreases because the system fails if the single switch malfunctions

Engineering Contradiction:
Improvesystem reliabilityVSAvoidconnector assembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The connector assembly is segmented into multiple independent electrical connections (first and second float switches) that can independently control the sump pump. This segmentation allows the system to maintain functionality even if one connection fails, thereby improving reliability without requiring a completely complex redundant system design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dual connector assembly serves multiple functions: it provides primary control through the first float switch, backup control through the second float switch, and maintains a unified connection structure to the sump pump. This multi-functionality allows a single connector assembly to handle both normal operation and failure scenarios.

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

2Reliability

If a dual float switch system with redundant connections is implemented, then the reliability improves by providing backup control, but the device complexity increases due to additional connectors and wiring

Engineering Contradiction:
Improveoperational reliabilityVSAvoidelectrical connection complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the first and second float switch connections into a single integrated dual connector assembly. This combining approach consolidates multiple electrical connections into one unified component structure, reducing the overall complexity that would otherwise result from having separate connectors and wiring harnesses for each float switch.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The dual connector assembly is designed to handle multiple electrical connections simultaneously while maintaining a unified structure. It provides both primary and backup control pathways through the first and second float switches respectively, allowing the same connector assembly to serve multiple operational functions without requiring proportionally complex wiring for each function.

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

3Reliability

If redundant float switches are added to prevent pump failure, then the reliability improves, but the ease of operation decreases due to more complex installation and maintenance

Engineering Contradiction:
Improvesystem continuityVSAvoidinstallation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By merging the first and second float switch connections into a single dual connector assembly, the patent simplifies the installation process. Instead of requiring separate installation procedures for multiple independent connectors, the unified assembly can be installed as one unit, reducing the complexity of installation and maintenance operations.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present application generally relates to a sump pump system configured for use in a sump that may contain liquid. In one embodiment, the system includes a sump pump, first and second vertical float switches having respective piggyback end plugs, and a dual connector assembly comprising first and second electrical connectors. Male connection points of each of the vertical float switch end plugs are plugged into respective female connection points of the first electrical connector, which terminates at a single male connection point plugged into an AC power source. The second electrical connector has a single female connection point and terminates at two male connection points. The sump pump is plugged into the single female connection point of the second electrical connector, and the two male connection points of the second electrical connector are plugged into the respective female connection points of the two piggyback end plugs.
