Solution Overview

Problem

Conventional septic systems face inefficiencies in waste decomposition due to enzymes settling and insufficient treatment time, leading to incomplete waste breakdown and potential sewage backup during power outages.

Innovation Solution

The septic system incorporates an aeration subsystem that breaks molecular bonds of enzymes and injects oxygen into liquid waste, creating an 'enzyme feeding frenzy' for enhanced decomposition, and includes a control subsystem for efficient operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If enzymes are added to liquid waste for decomposition, then waste breakdown is improved, but enzymes settle to the bottom of the tank and fail to reach floating waste material

Engineering Contradiction:

Improvewaste decomposition efficiencyVSAvoidenzyme distribution uniformity

Core Design Contradiction:

ProductivityVSStability of the object's composition

Solution Approach 1:

The patent employs mechanical agitation devices such as mixers or aerators that create vibrations and turbulence in the liquid waste. This mechanical energy prevents enzymes from settling by continuously moving them throughout the tank, ensuring they remain in contact with floating waste material for effective decomposition.

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The patent utilizes pneumatic agitation systems that introduce air bubbles into the liquid waste through diffusers or spargers. The rising bubbles create upward currents that counteract enzyme settling, while the hydraulic mixing action distributes enzymes uniformly throughout the tank volume, maintaining contact with waste material.

Inventive Principle:

Principle #29Pneumatics and hydraulics

2Productivity

If septic systems are designed for waste treatment, then waste disposal is improved, but insufficient treatment time leads to incomplete waste breakdown

Engineering Contradiction:

Improvewaste treatment capacityVSAvoidenzyme action time

Core Design Contradiction:

ProductivityVSDuration of action of moving object

Solution Approach 1:

The patent implements continuous aeration and mixing systems that maintain constant oxygen supply and enzyme-waste contact throughout the treatment period. This continuous action prevents treatment interruptions and ensures enzymes remain actively engaged with waste material for the entire retention time, maximizing decomposition efficiency.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The patent modifies operational parameters such as increasing dissolved oxygen levels through enhanced aeration, adjusting pH levels to optimize enzyme activity, and controlling temperature within optimal ranges. These parameter changes accelerate enzymatic reaction rates and extend the effective action period of enzymes on waste material.

Inventive Principle:

Principle #35Parameter changes

3Loss of energy

If power is removed from treatment systems, then energy consumption is reduced, but sewage backs up due to lack of pumping

Engineering Contradiction:

Improveenergy consumptionVSAvoidsewage flow continuity

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

The patent designs the system with passive gravity-based flow mechanisms and float-operated valves that automatically regulate sewage flow without requiring powered pumps. The system uses the natural hydraulic gradient and buoyancy forces to maintain continuous sewage movement, eliminating the need for electrical power while ensuring reliable flow continuity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent incorporates surge tanks or expansion chambers that provide a buffer volume to accommodate flow variations. These pre-designed cushioning elements absorb temporary flow increases or decreases, maintaining stable sewage movement through the system even when powered components are not operating, thereby preventing backup conditions.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A system and method includes an aeration subsystem that excites enzymes in the liquid waste passing through the septic system along with a bypass system that directs liquid waste during power outages. The bypass system utilizes a mechanically activated bypass valve moved by a float. The aeration subsystem includes a compressor section that compresses the liquid waste. The method includes mixing enzymes into the fluid waste material, compressing the fluid waste material with the compressor, injecting air into the compressed fluid waste material, and determining whether the fluid waste material is at a desired cleanliness, and if not, recirculating the fluid waste material through the compressor.
