Innovation Solution

Implementing an infiltration system management process that utilizes leading indicators to monitor and adjust operational parameters such as air flow, water flow, carbon introduction, and temperature, using sensors and an infiltration system manager to optimize soil moisture content, aeration, and microbial interaction, thereby enhancing treatment efficiency and preventing bioclogging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If infiltration systems operate continuously to treat water, then treatment efficiency is maintained, but bioclogging accumulates and reduces hydraulic conductivity

Engineering Contradiction:

Improvetreatment efficiencyVSAvoidhydraulic conductivity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system implements periodic air injection cycles into the infiltration field to prevent bioclogging. Air is injected at scheduled intervals to oxidize organic matter and maintain pore space, allowing continuous water treatment while periodically restoring hydraulic conductivity without system shutdown

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

Air is introduced as an intermediary substance to oxidize bioclogging matter. The air injection system acts as a mediator between the water flow and bioclogged zones, delivering oxygen to breakdown organic accumulation and maintain system performance

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If air flow is increased to prevent bioclogging, then hydraulic conductivity is maintained, but energy consumption increases

Engineering Contradiction:

Improvehydraulic conductivityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system applies partial air injection rather than continuous high-volume air flow. Air is injected at lower rates and shorter durations during critical periods when bioclogging is most likely, maintaining hydraulic conductivity with reduced energy input compared to continuous operation

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

Air injection is applied preemptively before severe bioclogging occurs. The system monitors conditions and injects air to prevent organic matter accumulation, requiring less energy than remediation after clogging establishes

Inventive Principle:

Principle #10Preliminary action

3Productivity

If monitoring and control systems are added to manage infiltration parameters, then system performance is optimized, but device complexity increases

Engineering Contradiction:

Improvetreatment efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system incorporates sensors that monitor water level, air flow, and operational parameters, feeding this data back to a controller that automatically adjusts air injection and water distribution. This closed-loop feedback optimizes treatment efficiency while automating complex control functions

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The control system serves multiple functions: monitoring water levels, controlling air injection timing and duration, regulating water distribution, and preventing bioclogging. This multi-functionality consolidates several control tasks into a single integrated system, managing complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Infiltration system management and operation is provided using leading indicators. These leading indicators may be sensed at various locations and compared to a target value or range or other criteria when making adjustments to blower, vacuum, pump, or valve operation of an infiltration system. Other operational components or parameters may also be adjusted when considering one or more leading indicator. For instance, sacrificial carbon sources may also be added or replaced based on the status of a leading indicator and its comparison to a target value or range.
