Solution Overview

Problem

Septic systems with grinder pump systems can experience unexpected failures due to power outages or mechanical malfunctions, leading to wastewater overflows into structures, and existing alarm systems may provide false security or fail to alert homeowners in time.

Innovation Solution

A passive overflow discharge system that includes an auxiliary storage tank or leach field system, which diverts wastewater away from the primary tank using manually or automatically operated valves, preventing overflow without electrical power and providing temporary protection until the primary system is restored.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a grinder pump system is installed to pump wastewater away from the structure, then the septic system can effectively remove wastewater, but the system may fail without warning due to power outages or mechanical malfunctions, leading to wastewater overflow into the structure

Engineering Contradiction:
Improvewastewater removal capabilityVSAvoidsystem failure risk
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent installs an auxiliary overflow discharge system that is pre-configured to activate automatically when the primary grinder pump fails. The system includes overflow outlets positioned at strategic levels and auxiliary discharge pathways that are ready to divert wastewater before it overflows into the structure, eliminating the need for preliminary detection or user intervention.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an auxiliary overflow discharge system as an intermediary between the primary grinder pump and the structure. This intermediate system includes overflow outlets and alternative discharge pathways that capture and redirect wastewater during pump failures, preventing direct contact between wastewater and the structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If float switch alarms are installed to detect high wastewater levels, then early warning of pump failure can be provided, but the alarm system can fail due to power loss or electrical faults, providing false security

Engineering Contradiction:
Improvefailure detection capabilityVSAvoidelectrical component vulnerability
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces electrical alarm systems with a purely mechanical overflow protection system. The mechanical overflow outlets and passive discharge pathways operate based on physical principles (gravity flow, pressure differential) rather than electrical components, eliminating susceptibility to power loss, electrical faults, and false alarms while providing continuous protection.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The overflow discharge system is designed to activate automatically based on physical conditions (wastewater level reaching overflow outlets) without requiring external power, control systems, or user intervention. The system self-regulates by diverting flow through passive mechanical pathways when needed.

Inventive Principle:
Principle #25Self-service

3Reliability

If a passive overflow discharge system is installed to prevent wastewater overflow during pump failures, then protection is provided even without electrical power, but the system requires additional components such as auxiliary storage tanks or leach field systems

Engineering Contradiction:
Improveoverflow protection during power failureVSAvoidsystem component quantity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates the overflow protection function directly into the existing septic system infrastructure by incorporating overflow outlets into the septic tank and connecting them to alternative discharge pathways. This merging approach combines multiple functions (wastewater storage, pump operation, and overflow protection) into a unified system, reducing the need for separate auxiliary components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The auxiliary discharge pathways and overflow outlets serve multiple functions: they provide overflow protection during pump failures, offer alternative discharge routes during maintenance, and can handle increased flow during peak usage periods. This multi-functionality reduces the need for dedicated auxiliary storage tanks or separate emergency systems.

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