Innovation Solution

A distributed yard maintenance management system that utilizes a robotic rover and networked sensor and task performance equipment, with processing circuitry for data processing and control, to monitor and adjust growing conditions across defined zones, enabling remote and local management for optimal vegetation care.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If manual monitoring and adjustment of growing conditions is performed, then system complexity is low, but labor intensity and time consumption increase significantly

Engineering Contradiction:
Improveautomation of monitoring and adjustmentVSAvoidsystem complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The system enables self-service automation where sensors automatically monitor growing conditions and the controller automatically adjusts task performance equipment based on sensor data, eliminating the need for continuous manual intervention while maintaining optimal vegetation care

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The controller serves multiple functions by receiving data from various sensor types (moisture, light, temperature) and controlling different task performance equipment (irrigation, lighting, heating), creating a universal management system that handles diverse gardening tasks through a single integrated platform

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

2Productivity

If distributed control system is implemented, then coordination efficiency of sensor and task performance equipment improves, but device complexity increases

Engineering Contradiction:
Improvecoordination efficiencyVSAvoiddistributed control complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The control system is segmented into distributed components including individual sensors placed throughout the garden, a central controller, and separate task performance equipment, allowing each component to operate independently while contributing to overall system coordination efficiency

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The distributed control system implements feedback loops where sensors continuously monitor growing conditions and transmit data to the controller, which then adjusts task performance equipment based on the received information, creating a responsive coordination mechanism that optimizes vegetation care

Inventive Principle:
Principle #23Feedback

3Ease of operation

If remote monitoring capability is added, then manual interaction is reduced, but system complexity and cost increase

Engineering Contradiction:
Improvemanual interaction requirementVSAvoidremote management complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The controller acts as an intermediary between sensors and task performance equipment, processing sensor data and generating control signals automatically, which enables remote monitoring capability without requiring complex direct connections between all system components

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A system may include sensor equipment, a local yard maintenance manager and a remote yard maintenance manager. The sensor equipment includes one or more sensors disposed on a parcel of land. The local yard maintenance manager may be disposed proximate to the parcel and configured to interface with the sensor equipment to monitor growing conditions on the parcel. The remote yard maintenance manager may be disposed remotely with respect to the parcel and configured to interface with the sensor equipment.
