Solution Approach 1:

The system enables automated self-monitoring of material levels through IoT sensors that continuously track tank contents and automatically generate transfer alerts and maintenance notifications without human intervention, allowing the holding tank system to serve itself

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual monitoring and control mechanisms are replaced with electronic IoT sensors, wireless communication modules, and automated processing systems that transmit data remotely and trigger alerts, substituting mechanical/manual operations with electronic automation

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

2Loss of time

If remote monitoring is implemented, then maintenance timeliness is improved, but device complexity increases

Engineering Contradiction:
Improvemaintenance response timeVSAvoidmonitoring system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

IoT sensors and wireless communication modules serve as intermediaries between the holding tank and remote monitoring systems, enabling distant observation and control without requiring complex direct integration between all system components

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The monitoring system is designed to perform multiple functions including material level detection, transfer alert generation, maintenance notification, and data logging within a single integrated platform, reducing overall system complexity through functional consolidation

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

3Stability of the object's composition

If automated material transfer control is implemented, then material level balance is improved, but device complexity increases

Engineering Contradiction:
Improvematerial level balanceVSAvoidcontrol system complexity
Core Design Contradiction:

Solution Approach 1:

The system continuously monitors material levels and automatically compares readings against predefined thresholds, triggering automated transfer alerts and notifications when levels require adjustment, creating a closed-loop feedback control mechanism that maintains material level stability

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system proactively generates transfer alerts and maintenance notifications before material levels become critical, allowing preventive action to be taken in advance to maintain optimal material balance and prevent overflow or depletion conditions

Inventive Principle:
Principle #10Preliminary action

AI summary

Methods and systems for remotely monitoring and controlling holding tank subsystems. One system includes an electronic processor communicatively coupled to a memory. The electronic processor, through execution of the instructions stored in the memory, is configured to receive tank data associated with a first holding tank of a holding tank subsystem. The tank data indicates a material level of a material stored in the first holding tank. The electronic processor is also configured to compare the material level to a material transfer threshold. The electronic processor is also configured to, in response to the material level satisfying the material transfer threshold, control the holding tank subsystem to transfer at least a portion of the material in the first holding tank to the second holding tank as a transfer event.
