Solution Overview

Problem

Conventional garden and houseplant probes are analog devices that lack automation and require manual operation, while automated watering systems are time-based and lack precision, making it difficult for gardeners to manage soil conditions and plant care effectively, especially for novice gardeners and those desiring organic and climate-friendly practices.

Innovation Solution

An automated plant probe system that communicates with a mobile device to determine local planting conditions and provide recommendations on planting, maintenance, and care, including sensors for moisture, pH, and growing media, with modules for weather, succession planting, and home automation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If conventional analog probes are used to measure soil characteristics, then the device structure is simple, but the automation level is low and requires manual operation

Engineering Contradiction:
Improveautomation levelVSAvoiddevice structure
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical probe operation with automated electronic sensing systems. Multiple sensors (moisture, temperature, pH, light) automatically collect soil characteristics without manual intervention, and the system processes data to generate care recommendations, eliminating the need for manual reading and interpretation of analog gauge readings

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

Solution Approach 2:

The probe system integrates multiple sensing functions into a single device, measuring moisture, temperature, pH, and light characteristics simultaneously. This multi-functional approach automates comprehensive soil analysis that would otherwise require multiple separate manual measurements, increasing automation while consolidating device functions

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

2Measurement precision

If time-based automated watering systems are used, then the operation is automated, but the precision of soil condition management is low

Engineering Contradiction:
Improvesoil condition measurement precisionVSAvoidgardening efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The system continuously monitors soil characteristics through multiple sensors and uses this real-time feedback to dynamically adjust care recommendations. Unlike fixed time-based schedules, the system responds to actual measured conditions, providing precise control over watering, fertilizing, and lighting based on current soil state rather than predetermined timing

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent implements dynamic adjustment of gardening parameters based on real-time sensor data. The system adapts watering, fertilizing, and lighting recommendations according to measured soil moisture, temperature, pH, and light levels, allowing flexible response to changing conditions rather than rigid time-based schedules

Inventive Principle:
Principle #15Dynamics

3Reliability

If multiple sensors and modules are integrated into the plant probe system, then the measurement precision and automation level improve, but the device complexity increases

Engineering Contradiction:
Improveplant care recommendation accuracyVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the complex probe system into modular functional components: moisture sensors, temperature sensors, pH sensors, light sensors, communication modules, and processing units. Each module performs a specific function, and they are integrated through standardized interfaces, allowing the system to achieve high reliability through multiple measurements while managing complexity through modular design

Inventive Principle:
Principle #1Segmentation
