Innovation Solution

A system for intelligent control of yard maintenance that includes sensors, a smart watering pump, and a user terminal for remote operation and programming, allowing for adaptive and automated watering based on real-time data and predefined schedules, with the ability to coordinate with robotic rovers and other maintenance tasks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual monitoring and management of growing conditions is used, then system complexity is low, but labor intensity and time consumption increase

Engineering Contradiction:
Improvemanual laborVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The watering pump automatically monitors its own operational parameters (runtime, water usage) and calculates maintenance intervals without external intervention. The system self-manages watering operations based on sensor data, reducing the need for manual monitoring and management while maintaining simplicity for the user.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors growing conditions through sensors and uses this feedback to automatically adjust watering operations. The processing circuitry receives sensor data, determines when watering is needed, and controls the pump accordingly, creating a closed-loop system that reduces manual intervention while managing complexity through automation.

Inventive Principle:
Principle #23Feedback

2Productivity

If automated watering control is implemented, then productivity and efficiency improve, but device complexity increases

Engineering Contradiction:
Improvewatering efficiencyVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into a single integrated watering pump unit: water delivery, operational monitoring, data calculation, and maintenance scheduling are all merged into one device. This integration improves productivity by automating these functions while managing complexity through consolidation rather than proliferation of separate components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The smart watering pump serves multiple functions: it delivers water, monitors its own operational parameters, calculates runtime and water usage, determines maintenance intervals, and communicates with sensors and user terminals. This multi-functionality increases productivity by consolidating tasks while the universal design manages complexity through a single versatile device rather than multiple specialized components.

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

3Ease of operation

If remote control capability is added, then ease of operation improves, but device complexity and communication requirements increase

Engineering Contradiction:
Improveremote controlVSAvoidcommunication system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The gateway serves as an intermediary between the watering pump and the user terminal, handling communication protocols and data transmission. This mediator approach improves ease of operation by enabling remote control while managing communication complexity by isolating it to a dedicated intermediate device rather than requiring complex communication capabilities in the pump itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If maintenance interval calculation is automated, then reliability of maintenance scheduling improves, but processing requirements and device complexity increase

Engineering Contradiction:
Improvemaintenance scheduling accuracyVSAvoidprocessing circuitry complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The processing circuitry continuously monitors operational parameters and preliminarily calculates runtime and water usage data in real-time. By performing these calculations continuously and maintaining running totals, the system is prepared to determine maintenance intervals immediately when needed, improving reliability of scheduling while managing processing complexity through incremental updates rather than complex batch processing.

Inventive Principle:
Principle #10Preliminary action
