1Ease of operation

If manual setup procedures are used for pump control design, then ease of operation is reduced, but device complexity remains manageable

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pump control system automatically detects system parameters, performs self-configuration, and executes self-commissioning without requiring manual setup procedures. The controller autonomously identifies pump characteristics, system resistance curves, and operational parameters through integrated sensors and algorithms, eliminating the need for manual intervention in the setup process.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary automatic detection and configuration actions before the pump enters normal operation. The controller pre-configures operational parameters, establishes control strategies, and validates system integration during the initial startup phase, so that the pump is fully ready for operation without requiring subsequent manual adjustments.

Inventive Principle:
Principle #10Preliminary action

2Extent of automation

If automatic self-driving capabilities are implemented, then extent of automation is improved, but device complexity increases

Engineering Contradiction:

Solution Approach 1:

The pump controller integrates multiple functions including automatic parameter detection, system characterization, control strategy generation, and operational optimization into a single multi-functional device. This universal controller can adapt to different pump types, system configurations, and operational requirements without requiring separate dedicated systems for each function.

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

Solution Approach 2:

The patent introduces an intelligent controller as an intermediary between the pump motor and the hydraulic system. This controller mediates the automatic detection of system parameters, processes sensor data, executes control algorithms, and adjusts motor operation accordingly, thereby enabling self-driving capabilities while managing complexity through a centralized control architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 1:

The system implements sensorless feedback control by monitoring electrical parameters (current, voltage, power factor) and using these measurements to infer mechanical system state. The controller continuously adjusts motor operation based on feedback from power consumption patterns and electrical characteristics, maintaining optimal performance without requiring direct mechanical sensors for position or speed detection.

Inventive Principle:

AI summary

An automatic self-driving pump system features a pump/motor/drive detector and an automatic self-driving and control design/setup module. In operation, the pump/motor/drive detector receives sensed signaling containing information about a pump/drive for operating in a hydronic pump system, e.g., stored in and sensed from a signature chip or barcode installed that can be scanned by a scanner, and provides corresponding database signaling containing information about parameters for providing automatic pump control design, setup and run to control the pump/drive for operating in the hydronic pump system, based upon the sensed signaling received. The automatic self-driving and control design/setup module receives the corresponding database signaling, and provides control signaling containing information for providing the automatic pump control design, setup and run to control the pump/drive for operating in the hydronic pump system, based upon the corresponding database signaling received.
