Solution Overview

Problem

Existing garden watering controllers are complex and time-consuming to program, with user interfaces that are difficult to use, and they do not adapt well to changes in daylight hours or weather conditions, requiring frequent adjustments to maintain optimal watering times.

Innovation Solution

A tap-mountable garden watering controller unit with remote control capabilities via a network, featuring a battery-powered electrically operated valve that stores a watering schedule and enters a sleep mode to conserve battery life, with a manual override for immediate watering and automatic adjustments based on geo-location data and weather conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a programmable timer-based system is used, then watering can be automated at specific times, but the system becomes complex and time-consuming to program

Engineering Contradiction:
Improvewatering automationVSAvoidprogramming complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The system automatically determines optimal watering times by monitoring weather conditions and soil moisture levels, eliminating the need for users to manually program complex schedules. The controller self-adjusts based on environmental sensors, making the system both automated and simple to use.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system incorporates sensors that continuously monitor soil moisture and weather conditions, providing feedback to the controller which automatically adjusts watering schedules. This closed-loop feedback mechanism replaces manual programming with intelligent, condition-based automation.

Inventive Principle:
Principle #23Feedback

2Reliability

If fixed programmable schedules are used, then watering occurs at predetermined times, but the system cannot adapt to changes in daylight hours or weather conditions

Engineering Contradiction:
Improvewatering schedule consistencyVSAvoidenvironmental adaptation
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The watering schedule is dynamically adjusted based on real-time weather data and soil moisture readings. The system transitions from static predetermined times to flexible, condition-responsive scheduling that adapts to changing environmental conditions while maintaining reliable watering.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Environmental sensors provide continuous feedback on weather conditions and soil moisture, enabling the controller to automatically modify watering schedules in response to actual conditions rather than following fixed predetermined programs.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If the controller continuously monitors conditions and allows remote adjustments, then adaptability improves, but battery consumption increases

Engineering Contradiction:
Improvewatering control flexibilityVSAvoidbattery consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The controller performs monitoring and communication in periodic cycles rather than continuously. It checks soil moisture and weather conditions at scheduled intervals and only communicates with the remote device when adjustments are needed, significantly reducing battery consumption while maintaining adaptability.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system autonomously monitors conditions and makes routine adjustments without requiring constant remote communication. It only engages the wireless communication module when user intervention is necessary, allowing continuous adaptability with minimal energy expenditure.

Inventive Principle:
Principle #25Self-service
